Seeing past 13.8 BILLION YEARS (The Big Bang) 🧐 w/Brian Cox #cosmology #bigbang

Is it possible that in the future we will be able to see past 13.8 Billion Years?
In this shorts clip Physicist Brian Cox and Joe Rogan discussed the possible scenario of seeing past the 13.8 Billion Years (or almost The Big Bang). By answering the question, Brian Cox explains that we currently cannot see light that was travelling from the time before 13.8 billion years ago because before that the universe was so hot that atoms couldn’t form. And there were only electrically charged particles existing, and it was too hot for electrons to orbit around nuclei. It’s almost like a Big Glowing Star. And when it was expanding, it cooled, past the point where the atoms were able to form.
In addition to that he adds that the most distant light we can see is something called “THE COSMIC MICROWAVE BACKGROUND RADIATION”, which was released 380,000 years after the Big Bang itself. And at that point it became transparent to see light in the Cosmic Time Scale. So therefore as the universe cooled down light could travel in straight light through the universe. But further back 380,000 years after the Big Bang we can’t see actual light coming from the Big Bang rather it’s possible to see it with Gravitational Waves.

I think the reason people admire Brian Cox is how he speaks so gently. He gives us a story, and able to explain complicated things easily

[hellnoo]

I'm jealous of the people who will exist in 5000 years or so, who will have figured out so much more than us

I adore Brian Cox, I have learned so much from him simply because of his patient quiet spoken clear way of explaining things so well. Thank you, you are one of the world's greatest treasures. ❤

I wish my brain worked well enough to understand how these guys come up with what it looked like before the Big Bang or the theories about the universe. Maybe one day they’ll come up with a visual representation of what they think to where I could understand it. It’s very intriguing and humbling. I wish I had that kind of brain

Everyone finds the Stars in the night sky interesting tho ive always found the darkness between them more interesting. The thought of infinite darkness/space is unfathomable.

Nobody can prove anything, so as long as you talk smart, you're fine

I have 1 question.

We say universe is expanding at some speed. But where the universe is expanding.

For example:- if we spill water on ground it will spread for a distance and it is spreading in ground right. So on what ground the universe is expanding

[fireiadmire]

How can you see all of that??.... fascinating 🤯😲

[louskunt]

Im getting up there and will be LONG gone by 2060, and im totally fine with it 😂

[varshavaghani]

How it's possible with gravitational waves can someone explain

[topcounts]

In 5 billion years we'll be able to see back 18.8 billion years

[murryburnett]

So if we can still see the light traveling in these straight lines. Why can't we look back to the convergence of all this energy at, say, 0, 0, 0. Then, see what is at this spot? Can you have a similar presentation on this.

Thank you Dr. Brian for sharing your knowledge and insights with us. You always make me feel better about our future 🌎💪 I hope you have a great rest of your y🌞

Those electrons orbiting the nucleus is making the nucleus decay

Ask him to clarify if he thinks the CMBR is a reflection back at observational devices from the center of the universe or just a really dense region of matter randomly in the universe that seems to be 13bn years old reflected back at observational devices roughly near the center the really dense region that wasn’t the beginning of the entire universe 😊

[Kadrimos]

Just a simple question:


Physically, what is heat composed of?

[GHOSTGHOST-jwmi]

Just to imagine what's passed the microwave background radiation if anything at all will we see other universes

[rocknral]

Well, now we've cleared that up....

[DrZaheerAbbas]

If CMB wouldn't have stretched that much we could almost see through CMB, or in Past if there were other technologically advanced Civilizations those were able to capture CMB at visible wavelengths must be able to see much more than we're right now .

[JCRFit]

Rogan waa hoping a grizzly bear can help with that
