The Big Bang Dilemma with Neil deGrasse Tyson

Are we rethinking the Big Bang? On this episode, Neil deGrasse Tyson and comic co-host Chuck Nice explore features of the James Webb Space Telescope, magnetism and how the aurora borealis works, and if the Big Bang is being debunked.
Learn how the JWST is more than just its pictures. What bands of the electromagnetic spectrum can the it see in? Find out about William Herschel and his discovery of infrared light. How does the JWST avoid detecting itself? Learn about features to keep the JWST cool and infrared-free.
Will Earth’s poles flip? We discuss Earth’s precession (wobble), bob, and flip. Learn about the magnetic poles. Does your compass actually point to the magnetic north pole? Are the north pole and the magnetic north pole the same thing? Why do we even have a magnetic field? Discover Earth’s molten core, creating a dynamo, and why dead planets like Mars don’t have one. How often do Earth’s magnetic poles flip? Find out what magnets and aurora borealis have to do with each other. Will something bad happen if the poles do flip?
We explore the frontier of scientific research and what ideas are being contested. We walk through the scientific process and experimentations. What are the core tenets of the Big Bang Theory? Could the Big Bang just be a small piece of a bigger theory? Learn about Vulcan, the hypothetical planet pulling on Mercury that was invented to save Newton’s Laws. When Einstein’s relativity came along, why didn’t Newtonian physics go away? All that and more on another episode of StarTalk!

Just to be clear for anyone wondering. North and south polarity are naming conventions. Historical South magnetic pole = north polarity Historical north magnetic pole = south polarity However, if you have a compass needle that points to the Historical North Magnetic Pole ( which is the South Polarity Pole ) you could arbitrarily say that the needle is of south polarity and thus it is pointing to a north polarity pole, therefore the Historical North Magnetic Pole becomes of North Magnetic Polarity. All these are arbitrary naming conventions.

[@martynelson6164]

Thank you! I was going to comment but found your reply and it's spot on. North is just a term to indicate direction with nothing to do with polarity. The compass is a tool. If the magnetic pole flipped tomorrow we would just start painting the other end of the needle. North would remain in its traditional location.

Dear Startalk, love your show please do keep up, way more worthy than another 100th "reality" shows and it cold be a long list of those. A couple of thoughts from me though, The Big bang Theory TV series I believe brought people closer to science that is after all not that boring but instead can be very exciting. Question here, I know I'm not an exclusive member just yet (though considering), regarding the Big Bang that was confirmed and widely accepted, in the process, has it been "investigated" what caused it in the first place? If you could tell in percentage points at what percentage scientists "focus" on answering the how and the why, such as 50-50? The reason I'm asking is that I've worked in improving in many different fields and surely the first step to understand the how, but my favourite is still the 5 Why, to find any root cause for any plausible cause. Shall we focus on the why the big bang happened? What chemical or other actions-reactions resulted to we all be here today? Being an Atheist myself this could probably clear the GOD question as well for many people. Thanks and Peace

[@BariumCobaltNitrog3n]

You realize no one knows that right? What caused the Big Bang (if there was such a thing) implies a cause, a trigger, a before. Imagine waking up in a car not knowing where you are, going 100 down the highway, and from looking out the window for one minute, you are asked where you "started" your trip a month ago. You don't know what country you're in, what a car is and why you are in the back seat with no driver. Some say God is driving, others insist it's Mohammed or Yahway or Bob. This is why I'm an Atheist, nature is too amazing to make up stories. No one knows what happened and there is no reason to think we should know.

Great content as usually, HOWEVER (I want you to hear the Neal way of saying and moving his hands at the same time ) If you can show that the way the measurement was done was flawed in some way, then naturally to data gathered from those experiments are more or less flawed, thus it is possible to change "existing physics". HOWEVER, for the most parts many of the measurements done are quite robust :D

[@codyj9983]

you missed the point that "experimentally verified science" doesnt get undone or thrown out when new ideas come along. If the experiment was found to be flawed in some way then it would be not have been "experimentally verified science".

[@LorielStarkWinterfell]

You are correct sir! Didnt think it that way. I was more just pointing out untill the flaw was found it was declared as such -> it makes objective truths. And when the experimental verified science turns out flawed more or less of the objective truths can/will change. The way NTD implied here was that what we allready established objective truths cannot be undone. But one last point. English isnt my first language so I might have understood that part incorrectly.

[@jazzcatt]

Wow @StarTalk I can't believe you didn't mention the magma extrusion where seafloor spreading at divergent plate boundaries happens. When lava is extruded at any mid-ocean ridge, the rock it forms becomes magnetized and acquires the magnetic polarity that exists at the time the lava cools. As the crust moves away from mid-ocean ridges, it contains a continuous record of the Earth's changing magnetic polarity. What I find cool is that they can get a pretty close approximation of how often the polar shift has happened in the past.

I’m curious about the magnetized portion of the core. Can the portion of the core that is hotter than the Curie temperature be magnetized? (Maybe the Curie temperature is higher with pressure?) If not, then the magnetized volume would be near the interface bet the core and the crust (or mantel). Also, temperature would be part of the complex dynamics of magnetic pole movement.

[@Silverorient]

When we see the distant infra red images of early galaxies, is it possible the dispersed dusts and elementary scattering of that/those early galaxies already have contributed to galaxies that appear near in distance and time to us? Or are there other sources of the elementary particles/waves that celestial objects close to us are formed from? Light from early galaxies is fastest thing that reaches us or it's effects I.e the big bang expansion and cooling forming elements that make up celestial objects close to us and even the elements that make up our planet..

William Herschel, an astronomer best known for discovering Uranus, made significant contributions to astronomy, including the discovery of infrared radiation. His work required foresight in terms of developing innovative observational techniques and equipment, such as his large reflecting telescopes, which enabled him to explore the cosmos in unprecedented detail.Comparing foresight between William Herschel and Neil deGrasse Tyson is a bit challenging as they operated in different eras and contexts. Herschel's foresight was crucial in advancing observational astronomy during his time, while Tyson's foresight lies more in his advocacy for science education and public engagement with scientific ideas instead of actually making any groundbreaking discoveries.

[@paramjotkaursodhi2408]

As explained by NDT that after the big bang the entire universe was primordial soup, I would like to add that it stayed in this manner for about 3 hundred thousand years after the big bang. We can't see before this as the all known forces of the universe were merged into one as the temperature was too hot so no photons could have ever travelled without colliding with electrons. In conclusion a major part of the Universe's history has been lost up to that time. Hope all queries about this are solved.

For the compasses, isn't it just more likely that they put an N and painted the south pole of the compass magnet red as a way to describe which way its pointing rather than describing the pole of the magnet itself.

Amazing episode! Thank you so much!!

Awesome episode again. Always quality content! I hope you get to cover these prevailing internet solar storm news or whatever. Just to give people the basic science facts about the Solar Storm minus the hype.

Badass images is an understatement from what we actually accomplished with Newton's laws of physics and gravity. Im so proud of NASA for the great James Webb Telescope, and also Space X too! What they are capable with so many smart minds that have come together is incredible.

Neil and Chuck are my favorite YTers to learn from. ❤

Amazing episode! The only thing I would love to have had more deeply explained was: how long does this magnetic flipping take to occur and what are the consequences of it for us humans, especially concerning our current technologies. And, by the way, also many species of animals rely on the magnetic poles for navigation and orientation, so it would impact the migratory movements of huge populations across the world and probably that is not something to be overlooked!

It takes a very long time, last I looked like 100s of thousands of years. There was a worry at one point about the field being down altogether for a time. But more recently evidence suggests that doesn't happen. It weakens a bit, but not enough to cause trouble. If we got a solar storm while it was weak that could cause more damage then it normally would, but that's about it. Otherwise it basically won't affect us in any real way. As for animals, that is more interesting. But it happens slowly. So they seem to be able to adopt to it. This wouldn't be the first time it has flipped. And we have evidence suggesting animals have navigated this way for millions and millions of years. So neither this form of navigation, nor the flip are new. Which suggests it won't have a large impact on these animals. Maybe when combined with humans impact for some it could be a straw that broke the camels back kind of situation. But overall, they won't likely care.

I think on the outer rim of our actual (not observable) entire universe, if you could travel much faster than light, you would find the carcasses of old heat deaths. Random quantum fluctuations create new big bangs and these push the old ones out even further, so that you'd never know they were there before. At some point in time (probably an unimaginably distant future) i think there will be another big bang, which will push the contents of the universe out to the outer edges of the entire universe, and it will just keep happening. Eventually i'd guess that there'd be two big bangs very close to eachother and simultaneously. But this would take an even more gargantuan period of time... A period of time so big it doesn't even bare thinking about. 10 to the power of a number that wouldn't even fit on the screen, years most likely. Just something i've been thinking about recently.... The universe leaving growth rings, like a tree.

Weird take... And I love it. I've daydreamed similar thoughts. 👍🏼

9:30(ish) - i just realized the link between "F=ma" and "e=mc²"...Force and Energy are kinda similarly defined, equals mass, times how fast something is moving (capped at Speed of Light)

I loooovvvveeeee long explainers!!!! Thanks a ton!!!!!!!!

[@Dan-id1rq]

Very nice explanation ❤

NDT has the most infectious laugh!!! Love ❤ this video!

28:55 Neil talks about how huge Mars's volcano is, but with Mars's lower gravity it can be taller. 38% is the mass on Mars vs Earth. Ojos del Salado (6,793ft / 1.286553 mile) tallest volcano on Earth. Olympus Mons (14 miles) height Also 435 miles across at base.

I fall asleep to you guys every night! Thank you for awakening the inner brainiac in me ❤
