Is the Big Bang Theory Wrong? | Neil deGrasse Tyson Explains...

Are we rethinking the Big Bang? On this explainer, Neil deGrasse Tyson and comic co-host Chuck Nice break down Big Bang skepticism and what’s going on at the frontier of astrophysics.

What are the core tenets of the Big Bang Theory? We explore the frontier of scientific research and what ideas are being contested. We also walk through the scientific process and experimentations. 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?

What bigger theory does the Big Bang fit into?

'Science is the only pursuit where you get bonus points for proving yourself wrong ' - Neil deGrasse Tyson
I was raised by a research scientist but I just love this concise phrasing of a familiar concept .

[NobbyYuri]

The way Neil made the connection of Einstein's Relativity Theory with Newton laws at the end made so much sense to me, never thought of that this way.

[MrAstrojensen]

When thinking about the universe, always remember this Neil deGrasse Tyson quote: "The universe is under no obligation to make sense to you."

[whitewalker]

Neil deGrasse Tyson is one of the scientists I can listen for hours and never get bored.

[JustinWillisDevilZ]

To me the big bang theory has always felt like a place holder until we really learn what happened.

Star Talk is the best show on all of YouTube 🙌

[allenloganson]

I'm so excited to listen to you, I was pushed through in school and have comprehensive problems with severe adhd and autism so if I'd known about your talkings would have been a tremendous help, which you are helping me now cause I still think about everything you cover and I will admit that I don't understand the math completely but I am just a big fan of everything you do.thanks for these videos

I wish I had more teachers like NDT growing up, his enthusiasm is contagious.

Things "observed" are often optical illusions. What seems factual is actually often incorrect. Train tracks "appear" to converge off in the distance but when one venturers out to the point of convergence one finds the tracks equally separated. One might think the train came from a single point. The only way to know for certain is to look further beyond the convergence point. Our technology can only look so far back and the illusion will always show a convergence even though there may be no actual convergence at all.

Neil makes it easy to understand. He has excellent communication skills, sense of humor

Star talk is educational and hilarious i love this channel 💪🏼👏🏼

My father came up with an excellent definition of absolute truth: "Absolute truth is that which, within a given system, occurs consistently over an infinite series of trials. Because it is impossible to do an infinite series of trials, it is impossible to have an absolute truth."
The truths from science can be inferred however, using the same principle of limits from the calculus: if there are enough consistent trials, then the truth may be inferred. Now truth becomes that which we currently know to be consistent; as soon as an inconsistency is found that can be replicated, we can justify moving on to a new truth.

"The virus is not transmissible airborne."
oop; new info:
"The virus is very transmissible airborne."

New replicable information; new truth.

One of the many reasons why I absolutely LOVE Star Talk!

Always delivering a thorough and eloquent DeGrASS(e) Kickin' to the turbulence social media poses!

Cheers to another brief journey through the cosmos (and mind) by our personal Astrophysicist ❤️🥂

I have a question, how about if the experiments are correct but our interpretation is wrong(in this case they fit the big bang) just like your example with planet Volcan. Don't you think that this could be a good reason for new theory? And what do you think is the appropriate way to do this?

[MJ-eqbw]

I'd love to have a chat with Neil. I have lots of questions to ask him. He makes everything so easy to understand. I just wish I had his intellect. What a legend!

[nikolatesla]

The data sometimes tells us what we expect to see. An example is in the early attempts to image DNA. We managed to snap a picture that fit the bill, but it later turned out that the substrate we'd put DNA on to image it happened to have an internal structure that looked a lot like DNA. The evidence we have shouldn't be thrown out, but the theory's we've placed around it should constantly be challenged.

[joanfregapane]

Great explanation! I love how Neil and Chuck help make physics entertaining and understandable!

[greenlee]

Dr. Tyson. I majored in engineering and have a minor in physics and math. I love your explanation of Newtonian physics and Einsteinian physics.
Even though I know all of this matter and energy cannot be created under classical physics, I believe there had to be a single point, i.e. big bang.
Please address the lasted JWST findings that suggests Galaxies older than our big bang.

Dear Neil: thanks for clarifying this discussion for us non-astrophysicists. I feel like when there is a big-scary-foundation-shaking debate in social media about the Big Bang, all I need is to do is ride it out for a little while, until you come up with a way to explain it to us in a way that we can learn. Much appreciated Sensei!
