StarTalk Podcast: Cosmic Queries - Black Holes & Dark Energy with Neil deGrasse Tyson, Part II

On this episode of StarTalk Radio, we bring you Part II of Cosmic Queries - Black Holes and Dark Energy. Neil deGrasse Tyson and comic co-host Chuck Nice are answering fan-submitted questions about what we know, and don’t know, about black holes and dark energy.
You’ll hear why a black hole’s consumption of matter does not overpower the evaporation caused by Hawking radiation. Neil tells us what’s actually “evaporating” during Hawking radiation. He also tells us two remarkable facts about black holes that are sure to blow your mind.
We discuss how a spy satellite accidently opened a new branch of astrophysics. Find out more about singularities. We investigate the singularity at the beginning of our universe and Neil explains when string theory needs to be brought to the table. Chuck shares how his son coined the word “ringularity.” We assess the possibility of black holes being used as an intergalactic highway system to connect one galaxy to the next.
Find out more about “white holes.” Discover more about supermassive black holes. We explore the nature of photons: how they can be pulled into black holes if they’re massless and why they travel along the fabric of spacetime. Adventure back in time to Sir Arthur Eddington’s expedition to uncover how light bends around the sun.
We ponder if dark energy and dark matter are “stuff” permeating from another universe into our own. Discover why light is trapped in our galaxy but gravity isn’t. We discuss the likelihood that intelligent life is more advanced than us. Lastly, Neil shares final thoughts on the delicate evolution of the tree of life.

I've never seen a more perfect blend of education and comedy. These two produce an excellent podcast together. There's a magic chemistry between Chuck and Neil. Chuck being afraid to put a finger in the belt as it was snapped was quite hysterical. "Gonna do this to my 5-yr old" - LOL

@@lonniecraig9074 depends on when you went to school. the term "black hole" was coined in 1967 and the first one was discovered in 1971. so, there is a possibility that your teachers didn't know what a black hole was when in your school. I don't know your age.

[@phonzy]

I UNDERSTAND WHAT CHUCK WAS SAYING, HE'S A GENIUS!!! We definitely need more minds like him in the STEM fields because I have no idea how he made that connection.

[@diphenhydramine6072]

I had a hypothesis that dark matter is a bunch of particles spread in different coordinates of the 4th dimension's axis and that's why it doesn't interact with itself. I also thought that it would have to mean higher that dimensions would give a gravitational effect on lower dimensions. But to hear Neil confirm that gravity can escape to other dimensions really helps my hypothesis.

[@kianwilliams1357]

You should ask Neil about your hypothesis for one of these cosmic queries episodes.

[@5jd1]

You are explaining photons here, the 4th dimension is time and photons travel on this in "Quantum Superposition" as explained at 28 minutes in. Hope that helps you with your theory. Dark matter being "Regular matter" that is effecting our universe from another "universe", while being undetected because light cannot pass this line, is actually a really really nice theory! yes but like 3 and 5 being the same, 4th being time between, "space-time" itself would be all of the 1st-2nd-3rd-4th-5th and 7th, with a 6thDimensional solution in between. Hope this helps too!

[@5jd1]

could we call the 6th dimensional, missing piece that our parallel "space times" are travelling on, "Dark Energy"? Come on Neil, lets get the board out!!!

3:53 Question: If a few black holes consume all the matter and they start evaporating can they feast of the vapor of the other black hole?

[@pulkitmohta8964]

That's a great question. Gotta get Neil's attention to this question

[@josepazsays]

Yes. But it's just so minimal, that it would take googol years to make a difference. A black holes will take so long to evaporate, that it might not even make a difference.

[@rager86]

13:38 I just imagined NDGT reacting exactly like this if Chuck was falling into a real black hole :’)

I’d love if you guys could do remixes of the most popular episodes of these and add in visualizations and direct references to literature that we could read more of on certain subjects Neil talks about

[@FanEAW]

Hey neil and "chuck", i love both of you as you both were huge influences in my life, i had previously planned to commit suicide until i found startalk and it influenced me into getting in physics in university. So thank you. The question is for a friend and me: since mars doesnt have an intrinsic magnetic field, if we start terraforming mars we need a few things: water (melting the polar ice caps, extracting deep underground water, or even knocling asteroids or meteors that contain water), heating the planet through mirrors or burning fuel to create greenhouse gasses (or importing them from earth), and finally you need to thicken up the atmosphere (greenhouses gasses help us in this case again) but at what point would you need giant electromagnets (or something similat) to create a planetary-wide magnetic field to hold this atmosphere? Could we in theory start exporting greenhouse gasses until a threshhold is reached for the mars atmosphere? Or do we need giant magnets from the get go?

[@thomaslane1547]

I'm not Neil, or even Chuck, but... I think we would need giant electromagnets or an equivalent, if only to protect us from solar radiation and cosmic rays. Glad you're still with us.

[@stephanienirenberg7426]

[@WilliamBurlingame]

This is a great series. I have a lot of new things to learn since I got my BS in physics in 1958. I didn't work in the physics field, but in the computer field as a programmer. New information in both fields is coming in faster than my old brain can handle it.

[@JA238979]

Good choice! New information is coming in faster than anybody can handle, so your brain is right to reject most of it. You might learn a lot by sharing your knowledge, if you want to. When I started with community college, I found that most of the professors were experienced people like you. I was too bad at calculus to consider a major in physics, but we all use physics every day.

17:32 What if a white hole IS the universe?

[@lonniecraig9074]

'I think thats called 'racisim ... :)

[@Stratonetic]

@@lonniecraig9074 No, that would be if I asked why there's so many black holes. Edit: But I think it goes noting that black holes are within the universe, there are many of them, they absorb things and naturally evaporate, now let's think of the opposite, something that is not within the universe, there's only a single one or none at all, they repel things and grow, a white hole. The only thing that I can think of that does this and continues to do so is the universe, there's no white holes that we see in the universe, we have not ever found evidence for one, so what if our universe is a white hole that is expanding, as it should do indefinitely if a white hole is truly the opposite of a black hole and there's evidence that our universe should expand forever. Perhaps every time a black hole absorbs something, a white hole is born in the multiverse, but not like it popped into existence next to our universe, but within that black hole that is within our universe, maybe our universe is one of many white holes in a black hole that absorbed something, whatever it was, in another dimensional plain, like how we live in a third dimensional plain, maybe a black hole in the fourth dimension contains the pocket of white holes that also includes us, or maybe our black holes creates fourth dimensional white holes that spawn 4D universes, which would mean a 2D black hole made our 3D universe. I really do hope we figure out more about black holes and why our universe exists within my lifetime.
