rgower · 6 months

Neil, creator of The Sagan Series here. This post isn't really a question but I hope it gets seen.

I literally just yesterday did a TEDx talk (my first time public speaking) about The Sagan Series and Carl Sagan's impact on my life. I was horribly nervous but while I was backstage pacing about, I thought to myself how important Sagan's message is compared to my momentary timidness. Slowly my nerves melted away, and the talk went swimmingly.

I've always felt immense responsibility "speaking on his behalf" and I suspect you've felt similarly with your reimagining of Cosmos. It's a lot to live up to, and I just wanted you to know that if you or your production team think I can help in any way, please let me know. Promoting science in the public eye with media has consumed my entire life lately, and I absolutely love doing it. I even branched out recently with The Feynman Series. Don't for a second think I haven't considered the idea of a Tyson series. Your words for science are too passionately infectious to go underappreciated.

A very sincere,

Reid Gower

If there is one single accomplishment you'd like to see in space exploration or discovery within your lifetime, what would it be?

WholeWideWorld · 4 months

Here is a compilation of the top questions and their answers so far:

Question	Answer
Since time slows relative to the speed of light, does this mean that photons are essentially not moving through time at all?	yes. Precisely. Which means ----- are you seated?Photons have no ticking time at all, which means, as far as they are concerned, they are absorbed the instant they are emitted, even if the distance traveled is across the universe itself.
What do you think it will take for the US to seriously reinvest in the space program?	A foreign threat. That seems to be the only thing around that motivates bickering political parties to act in harmony.
If you could add one course to a student's curriculum, what would it be?	Course title every university should offer: "How to tell when someone else is full of shit"
What never fails to blow your mind in physics?	1) The fact that an electron has no known size -- it's smaller than the smallest measurement we have ever made of anything. 2) That Quarks come only in pairs: If you try to separate two of them, the energy you sink into the system to accomplish this feat is exactly the energy to spontaneously create two more quarks - one to partner with each of those you pulled apart. 3) That the space-time structure inside a rotating black hole does not preclude the existence of an entire other universe. MindBlown x 3
Can we inspire more kids to pursue space-related science and research? If so, how?	Kids are never the problem. They are born scientists. The problem is always the adults. The beat the curiosity out of the kids. They out-number kids. They vote. They wield resources. That's why my public focus is primarily adults.
What is your favorite short science fact you like to tell people to really make them think?	That our bodies atoms are traceable to supernova stars that scattered their chemical enrichment across the cosmos, spawning the birth of star systems that contain planets, at least one of them containing life.
What do you consider to be your greatest accomplishment scientifically? In life as a whole?	Made a prediction some years ago that there were 10x as many galaxies in the universe than had then been catalogued. based on a careful review of observation bias in how people obtained data on the universe. The actual number turned out to be about 5x as many galaxies. I got the wrong answer but for the right reasons, and it stimulated much further work on the subject.
What seemingly far-fetched aspect of science fiction do you think humans will reach first? (For example: Time Travel, lightsabers, invisibility, etc.)	None of it. Not even the costumes.
When will Cosmos series 2 air, and will it air in the UK?	Thanks for asking. Spring 2012. On FOX network. Likely primetime. UK will likely follow shortly thereafter.
Will our minds ever be able to truly comprehend the vastness of the universe?	I lose sleep worrying that we, as a species, are indeed simply too stupid to figure out the universe. There's even some YouTubes of me offering this lament. I other words, we are not as candid as we should be about our neuro-biological limitations.
You've always been an inherently funny guy. Will that transfer to your take on Cosmos, or will you seek to emulate Sagan's more sober wonder?	Excellent question. Sagan's "sober wonder" was a fundamental dimension of Cosmos's gravitas. Something that we all in this new production deeply respect. But I can't be something I'm not. Nor should I be. So right now we are exploring the best mix of sober wonder, charming humor, and intellectual depth. I think we'll land in a new place, respectful of Carl's legacy, but allowing me room to express my pedagogical enthusiasm for the subject.
Do you agree with the idea (Carl Sagan was a proponent) that humans should prepare to, one day, forever leave the surly confines of Earth? In other words, should we plan to colonize other planets?	Because it would be fun. And because we will probably learn something new about ourselves and our own planet. But not as a place to escape from an incoming asteroid. For that I'd rather stay on Earth and deflect the damn thing.
Who are the unknown scientists of the 20th Century that people should know?	M. Burbidge, G. Burbidge, W. Fowler, & F. Hoyle. Google them.
If you could change one thing about how the sciences are taught to American children, what would it be?	Create a goal state for educational pipeline to see in broad daylight - some ambitious mission - like a voyage to mars - that is so compelling that the quality of your science teacher is irrelevant. Your consequent ambitions trump all other forces.
If you could impress one thing on young people today, what would it be?	That adults are not all they're cracked up to be. And most of them are wrong most of the time. This can be quite revelatory for a kid - often launching them on a personal quest of exploration, rather than of Q&A sessions with their parents.
What is your favorite sci-fi movie?	Three-way tie: The Matrix - The first one, of course. Contact Deep Impact. And classical have: 2001 A Space Odyssey.
What are your thoughts on the reports of neutrinos traveling faster than the speed of light?	Three options:1) Mistake in the data VERY DISTANT 2) New particle traveling backwards through time. No need to modify relativity. EVEN MORE DISTANT 3) Need to modify Relativity.
What is your opinion of the Symphony of Science videos?	Only when creative people take ownership of cosmic discovery will society accept science as the cultural activity that it is. And so I applaud all such efforts of artists.
What do you think will be the biggest scientific breakthrough upcoming in the next 50 years?	Life elsewhere in the solar system. Mars, most likely.
Have you fixed your time machine yet?	Yup. That's what happens when I let Stewie touch my stuff.
What is your favorite fact about the Universe?	That is will never end. That it's on a one way trip of expansion. Something that many find to be philosophically unsettling. My view is that if your philosophy is not unsettled daily then you are blind to all the universe has to offer.
If a taco and a burrito are traveling near the speed of light and collide, will the result be delicious?	The result would be an explosion large enough to destroy a small village. high speed collisions do that, whether or not they are made of Mexican food.
Your thoughts on the upcoming Cosmos series? And thanks for all you do, you are like a rockstar in our household!	Loooong overdue. Last one was 31 years ago. A generation, that it.
How was it being a guest star on The Big Bang Theory? Do you think the show hurts or helps the perception of physicists?	The funnest 24 hours I ever spent in my life. Flew to LA from NYC in the AM. Returned on the RedEye. It's mainstreaming the culture of science. Note to those who criticize it: Where were you when scientists were always portrayed as lab-coat donning crazy people hell bent on destroying the world?
If you appeared on the game show Jeopardy, how do you think you would do?	I've appeared on the Jeopardy board (a video clue) about three or four times. I think one was even a daily double. If I were a contestant, I'm sure I would make the first few rounds, but would surely lose in any tournament. The people who win these things have a different brain wiring than I have. Part of me echoes Einstein's edict: never memorize what you can look up in a book.
What one improvement would you make to the way our society as a whole approaches science if it were within your power?	Society needs to see science not as a luxury of funding but as a fundamental activity that drives enlightenment, economics, and security. Science agencies should never have to go hat in hand to congress. One idea would be for the USA (or any other country for that matter) to earmark 10% of its budget to R&D. Like a good startup company might do. That way everyone knows what to expect annually. And long term research projects will have some hope of funding stability.
Just checking in today me and the wife adore you and we are thankful for all you're doing for a better understanding of science. Cheers from Brazil.	Gotta love Brazil: Soccer. Mardi Gras. Thong bikinis. And the third largest aerospace industry in the world.
What do you think about Ancient Aliens?	It's what people say when they can't figure out how ancient humans accomplished something. Rather than say, "I'm too stupid to figure this one out on my own", they say, "I am smarter than these ancient humans, and since I can't figure out what's going on here, they must have had help from aliens." We need more hubris in this world.
What exactly do you do these days? Are you a fan of cats? What do you think of the current space-travel situation?	1) My life is not especially private of late. So everything you see me do it what I do.2) cats can be cute, and all. But in the end, I think there's no substitute for a dog. I walked dogs for money as a kid to pay for a telescope and my first SLR camera.3) Current space travel situation is fine, if you are not American.
Neil- As a new social studies high school teacher, how can I best impart a love and respect for science and the importance of learning to my students who see school as a waste of their time? I struggle with this aspect of teaching more than any other.	I thrive on exploring all the ways science impacts life, society, and culture. It's the founding principle of StarTalk radio: http://startalkradio.net/ So a goal as teacher, perhaps ought to include knowing as much as you possibly can about pop culture and referencing it at every turn as you teach the syllabus. I am there with my Tweets: http://twitter.com/#!/neiltyson Takes a while to build up that utility belt of songs, TV shows, harry potter, etc. But it pays great dividends.
What are you feelings on religion and the afterlife, and are you scared to die?	I remain unconvinced that anything other than rapid decomposition is the fate of my body and mind after death. I've accomplished enough in life so that I do not fear death. In fact, I've left instructions for my Epitaph - a quote from the educator, Horace Mann: "Be Ashamed to Die, Until You Have Scored Some Victory for Humanity". That's the creed I live by. And will die by.
Do you think that Humans in our lifetime will achieve the technology to be able to live forever? If so, what is your greatest dream that you may someday be able to do that we don't yet have the technology to do?	Yes, I think it's inevitable. But that would eventually make for a very crowded Earth. So perhaps that's what we need to jumpstart the space program. Would love to live long enough to know what dark matter and dark energy actually are.
I just want to say that I can't wait for your new Cosmos series. And I also love it whenever you appear on The Daily Show. That is all.	Thanks. We're all working hard on it right now. Except, at this moment, me.
When do you think we would be able to explore Europa, given the current pace and funding of space exploration?	Europa is not on the planetary scientist's priority list, for an obscure combination of reasons that relate to cost and whether we are technologically prepared to undertake such mission versus missions to other tasty targets in the solar system.
What do you prefer NASA to explore more of?	Asteroids that might one day hit us.
What is the simplest thing in your life that makes you happy?	Watching a person learn something new - not simply a new fact (those are cheap and easy) -- but achieve a new understanding for how the world works. That's the only reward a (true) educator ever seeks.
What is your opinion on the whole idea of the technological Singularity and do you think such a monumental leap in science and technology is ever likely to happen to the degree that Moore's Law supposedly dictates (according to Kurzweil)?	I find the entire movement to be entertaining, in spite of my skepticism that the singularity will have the meaning ascribed to it. I'm primarily pissed off that they stole a perfectly good word from black-hole physics.
What are some very interesting DIY science experiments that a person can do as hobby?	There's no substitute for Oobleck. Easy to concoct in the kitchen. Weeks of amazing experiments on the counter. Google it.
What issues or ideas keep you up at night? Also, are you a Queen fan?	That America has lost its technological and scientific compass. Gotta love Brian May and his PhD in astrophysics. First heard Bohemian Rhapsody on the radio when I was only half asleep. An incident like that can accidentally alter your brain wiring.
What is one of the most common misconceptions about space/time/astrophysics that you encounter, and how would you clear up that subject?	That the north star is the brightest in the night sky. I'd guess about 9 out of 10 people think this. But it does not require a grant from the National Science Foundation to learn the answer. The North Star is not even in the top 40 in the night sky. It's the 49th brightest star. Rather dull and boring by most measures.
What are your thoughts on cryogenic preservation and the idea of medically treating aging?	A marvelous way to just convince people to give you money. Offer to freeze them for later. I'd have more confidence if we had previously managed to pull this off with other mammals. Until then I see it as a waste of money. I'd rather enjoy the money, and then be buried, offering my body back to the flora and fauna of which I have dined my whole life.
What are you most proud of at the Hayden Planetarium? What current exhibit should a visitor absolutely not miss?	Birthing a scientific research department of Astrophysics. You don't see them but it's a thriving department with faculty, postdocs, graduate students, research publications etc. In this world administrative victories are always the greatest.
No question, I just want to say thank you for sharing your breadth of knowledge with us and the rest of the world while being generally cool about it.	it's really a two-way street. If people didn't enjoy it I wouldn't do it. I'd just stay home and work.
Hi Neil, I'm a massive fan! I'm currently a junior in college studying physics and want to pursue a PhD. Do you have any advice for the next generation of scientists like me?	There are street artists. Street musicians. Street actors. But there are no street physicists. A little known secret is that a physicist is one of the most employable people in the marketplace - a physicist is a trained problem solver. How many times have you heard a person in a workplace say, "I wasn't trained for this!" That's an impossible reaction from a physicist, who would say, instead, "Cool. A problem I've never seen before. Let's see how I can figure out how to solve it!". Oh, and, have fun along the way.
what is the key to rooting out the anti-science view in America, especially in regards to things like evolution and climate change?	I don't mind anti-science views. We've all bought into America being free - which means, above all else, freedom of speech. What concerns me is when those who are anti science, try to prevent others from doing science. When that happens, that's the beginning of the end.
What do you think about the state of science reporting? Is there more of a burden on the scientific community to articulate their findings to the media, or on the media to be more informed before they report? Or should one side just step up?	It's much better than a few decades ago - in quality and especially quality. Documentarians have raise the bar on the depth of science that gets talked about on television. And there's no end of science on line. In the 1970s you could go months before you saw any news or treatment of scientific discoveries. Now you're treated to them weekly, if not daily.
Holy crap. I don't know what to ask you but I.. I just wanted to say hi Neil.	Yo. I suppose you can live vicariously for these next few moments.
What do you think needs to be changed to the current education system in the US?	Not enough space or time here to rant on that one.
Hello! What inspired you to be an astronomer? How old were you when you decided to do this career path?	That's why I wrote this book: :"The Sky Is Not the Limit: Adventures of an Urban Astrophysicist" http://www.haydenplanetarium.org/tyson/buy/books/the-sky-is-not-the-limit it all started at age Nine. And it was the universe that called me.
If you think 5 and 10 years from now, what are you most looking forward to in science? Any expectations?	Cure for Cancer. Fully funded space exploration. Physics recognized as the foundation of chemistry. Chemistry recognized as the foundation of biology. And free market structured in a way that brings these discoveries to market efficiently and effectively.
Do ever feel pressured into being the figure-head for promoting people into supporting astronomy? That's how I view you. :D	No pressure at all. Instead, I feel compelled to get people to support science for their own survival.
Would you run for president?	No: [1] http://www.haydenplanetarium.org/tyson/read/2011/08/21/if-i-were-president
What do you think of the current downfall of the History channel and it's onslaught of psuedo-scientific programming on ancient aliens, monsters, ghosts and other ridiculousness?	Do we blame them or the viewers who watch it?
Do you believe that we will see civilian trips into space during our life time that aren't millions of dollars to book? How about a manned trip to Mars?	No. But millions of dollars is a good start. I'd buy a lottery ticket for that.
If there is one single accomplishment you'd like to see in space exploration or discovery within your lifetime, what would it be?	Search for aquatic life in the oceans of Jupiter's moon Europa.
You know what reddit is and are doing an AMA? Watch out guys, we're dealing with a badass over here.	I've always admired the intensity of arguments that unfold on these pages. Happy to partake, even if only briefly. In fact it is here that I must resume my day and part ways with the Redditverse. Farewell to all. Maybe we can do this once a month. In the meantime, my tweets are live: http://twitter.com/#!/neiltyson As always, keep looking up. -Neil deGrasse Tyson
How does it feel to be voted 'Sexiest Astrophysicist Alive'?	I always wanted to be respected for my mind...But seriously, it turned out to be much more harmless than I had feared. More a fun novelty than either a curse or a burden to carry
Hey Neil! Saw your post on Twitter (Il_Cattivo_666 on there) Following the massive downsizing of our space program here in America, who do you think is going to fill the gap that we've left, over the next 10 to 20 years? Will we see Russia re-emerge as the major space-goer? Or do you think the ESA will expand it's role in operating the ISS?	Forgive the cheap plug, but I just wrote a whole book on this, to appear in Feb 2012, titles "Space Chronicles". I originally called it "Failure to Launch" but the publishers nixed the title, citing it was too depressing. Here's the listing for a pre-order, if interested. http://www.amazon.com/Space-Chronicles-Facing-Ultimate-Frontier/dp/0393082105
What is your opinion about science/math education in high school? It seems to me like we emphasize far to much on facts that most people will never need, rather than encouraging people to think creatively and logically.	Agree 100%. Any time we are answer-driven rather than idea driven, we have lost the true meaning of education.
Who do you look up to?	My parents. Still alive and married 59 years.
What are you scared of?	I'm too rational to be deeply scare of anything. But I'm deeply worried for America.
Where are the aliens?	We are too stupid to interest them. So they go elsewhere.
Favourite Star Trek character?	I'm old-school: Kirk. Then Spock a distant second. Then the tribbles.
Don't really have much of a question, just wanted to say that you visited my undergraduate university (Western Kentucky University) and gave an electrifying discussion about how religion holds back scientific progress, while not making religion out to be the problem.	Just to be clear...It's not that Religion holds back science, it's that dogma-in-charge holds back science. And since Religion is a form of dogma (almost by definition of the word), then if religion is ever in charge of a political state, it will most assuredly hold back science.
What food do you never get tired of eating?	Strawberry Malt.
What is your favorite celestial body? Why? (BTW just have to say I <3 the vest)	Saturn. Without a doubt. Just one peek at it through a backyard telescope and you might just agree with me.
Is it possible for humans to ever discover the "edge" of the universe? Is there really any "end" to it?	No edge. Any more than the horizon at sea is an edge to the earth.
