Brian Cox - Is The Whole Universe Inside a Black Hole?

Brian Cox - Is The Whole Universe Inside a Black Hole?

Professor Brian Cox explains the science behind black holes and the beginning of the universe.
Virtually all cosmologists and theoretical physicists endorse the idea that our universe started with the Big Bang. However, problems with dark matter, dark energy, and cosmic expansion have some astronomers rethinking what we know about the early universe.

Our Universe appears to be expanding and cooling, having originated some 13.8 billion years ago in a hot Big Bang. However, it's plausible that what we see from inside our Universe is simply the result of being inside a black hole. This is one of the most fascinating, and yet least discussed, possibilities in modern physics.

Brian Cox and James Beacham discuss the possibility of our whole universe existing inside a black hole.

So if we are possibly existing inside a black hole, could it be that our big bang was actually the collapse of the star that created the black hole that we exist in?

[osylphx]

If this is true, then it's assumable that within each black hole observable to us, there is a "mini" universe (mini relative to us). Also, if this is true, it's further validates the concept of a fractal universe, whereby a universe contains multiple universes within it, and that universe is inside another universe along side other universes... bubbles within bubbles within bubbles, forever and ever... Love it!

Professor Brian Cox's voice has a supernatural ability to calm the human mind and melt away all the accumulated stress. That's why I like to listen to him and learn a lot of interesting information at the same time.

This is quite mind-boggling, and I can listen to Brian Cox talking about it all day. His way of presenting is quite mesmerising.

[OriginalPuro]

Brian Cox is a gem, a fantastic spokesperson for science and a great scientist.

Science is cool, but preserving the sanctity and greatness of the United States is cooler. Trump 2024.

Grappling with infinity is such a mind-breaking concept that we are not built for. Respect to all the scientists who try to understand our reality while knowing they will never be close to all the answers in any of our lifetimes.

[imanolherrero]

At the center of a black hole there is a singularity with "infinite density." What if the way in which we view infinite density is actually describing an infinite expansion of a universe at the singularity within the black hole? Mind boggling and thought-provoking video, thank you.

[chadx]

At the moment of the universe coming into existence, all the matter was packed tightly into a tiny amount of space. Sounds like a black hole to me!

[MrTorleon]

Brian Cox, one of the best, one of the most modest science communicators that we are fortunate to have around at this time - always interesting, always able to some how explain complex and difficult concepts in such a way that most of use will feel we have at least grasped something, to feel excited about :)
Now, if only the scientists could find an effective way to pack all the world advertising into a small space, and send it into a black hole - that would be a real achievement :)

"thank you for uploading these videos. Even if I'm having a hard night, I just put a relaxing astronomy video on and listen. It always makes my nights go much easier.

Thank you!!!"

[seneca]

I wonder why it is, then, that we have observed black holes. Does that mean there are black holes inside of black holes?

[CJB]

The idea of living in a black hole is oddly comforting. Who knows if it’s true. But the idea of near total destruction of matter and then reformation just jives well for me given how our earth has similar cycles in things like geology, the way life forms die and are distributed into the earth and eventually become other things. From a purely romanticized view of the universe, it warms my heart to consider that nothing is ever truly destroyed. 😊

[Martimus]

This idea could actually answer a lot of unanswered questions about the beginnings of the universe. A massive star collapses onto itself and creates a singularity. That singularity contains a huge amount of compressed mass and energy. The singularity was the foundation for the big bang. It's also the foundation for the creation of a black hole. As such, maybe what we describe as the big bang was actually the creation of a black hole from the inside. The transfer of mass and energy from the singularity into the black hole (our universe) would follow along with the principals of "conservation of energy" and "conservation of mass". Inflation would follow along with the growth of the black hole.

I have no clue whether or not there is any truth to this but it'll be interesting to hear future scientific debate on the subject.

[GlowboxD]

Been interested for years, but never really heard a discussion based solely around this concept. This was cool, and I can see, that the idea of chasing a horizon which is unknowable to us can be similar. It's a nice thought experiment, and if the math works too, well, there ya go. Thanks for the video.

Fascinating upload - incredibly complex ideas explained in ways that are actually understandable to we lesser mortals.

[stefanpolihronopoulos]

This made my heart race as I have have quietly harbored such a notion for many years, now.

[apolesse]

You’re the best thing to happen to you tube physics lessons!!

[nWbeatty]

binging universe/astro physic vids on here a long time.... This was thE coolest most interesting 10mins maybe, ever.

[ohraisins]

Brian is amazing! Personally, I think that the universe has always been around and black holes are its way of recycling and regenerating itself. Goodness knows where the matter that goes into a black hole goes, but it must go somewhere. That's my hypothesis with my google phd. :-)
