Brian Cox - What's The Biggest Mystery in The Universe?

Brian Cox - What's The Biggest Mystery in The Universe?

English physicist and professor of particle physics Brian Cox explains some of the biggest mysteries in the universe.

Modern physics has given us a glimpse of what the true nature of the universe is. But there is still so much more to explore. One big mystery in science today is the The matter-antimatter asymmetry problem. But to better understand this complex issue we have grasp the nature of antimatter.

Brian Cox explains what antimatter is and how it's made at the LHC.

The Big Bang should have created equal amounts of matter and antimatter in the early universe. But today, everything we see from the smallest life forms on Earth to the largest stellar objects, is made almost entirely of matter. Comparatively, there is not much antimatter to be found. Something must have happened to tip the balance. One of the greatest challenges in physics is to figure out what happened to the antimatter, or why we see an asymmetry between matter and antimatter.

Our universe is a beautiful, elegant and strange, mysterious place at the same time. It has baffled curious minds since the very first humans gazed into the night sky and wondered what's out there.

While physicists can confidently say what happened a billionth of a second after the big bang, the vast majority of the universe remains unknown. In fact, we only understand about 5% of the total composition of the universe, which is ordinary matter. The other 95% which consists of dark matter and dark energy, remains in the realm of unexplained cosmic phenomenon.

It’s also the engineering that goes behind all of these discoveries, that amazes me.

The moment one thinks he understood something, the things become even more compelling.
That's the ever investigative nature of science that's fascinates me.
And accepting we don't know some things yet is a first step towards greatness.

[garypriestley]

There's a quote from the book "A Short History of Nearly Everything" by Bill Bryson that I love, "Two-thirds of the universe is missing from the balance sheet, we might as well call them DUNNOS - Dark Unknown Nonreflective Nondetectable Objects Somewhere" 😂

[bretta]

It's mind blowing how complex the LHC is.

[steeleye]

Our best theory atm is QFT which is based on a fabric of the universe having multiple values at every point in space and interacting. What is this fabric and what allows it to have values. And if you answered that, what would that thing be made of.

So the biggest mystery is that nothing is fundamental and components are made of other things for infinity. As well as going on for infinity in space and time as well. My head hurts, I'm gonna watch Love Island and have a nap.

Consciousness, the physics of consciousness is the greatest mystery that humbles all others

[abhorrentheathen]

I could listen to Brian Cox all day. He's so knowledgeable and his voice is as soothing as a Bob Ross video 😌

[henrikduende]

Something that bothers me a lot the older i get is the fact that like 99, 9 of us will never SEE What the universe looks like being IN the actuall universe. We see all these pics but we might not realise that we are like a grain of sand in size compared to the stuff in the pictures

[jakemoeller]

Particle Fever is one of my favorite documentaries! I am hoping that the LHC and future machines will unlock and showcase more of this beautiful universe.

[graceygrumble]

My brain hurts when trying to understand this, yet I still find the bits I can understand fascinating.

[markberman]

What if, in certain specific situations and places within the universe a spacecraft could scoop antimatter to recharge its engines and ride a wave path to the next scoop pathway like a gas station to get to a given far, far destination.

This would imply that antimatter exist and performs in some ways not yet understood, but is not unconquerable but can be used as fuel once we can find those place where it concentrates and build engines and craft the go beyond our current paradigms of understanding.

[sipplix]

I wonder if in the collision of matter and anti matter, a third neutral type of matter was created and as it built up it had a slight effect on the reaction between matter and antimatter causing an imbalance and leaving only a small amount of matter no antimatter and a large amount of this neutral matter?

[sinebar]

Dark matter is locked up in spacetime itself. Kind of the way photons are locked up in electromagnetism. Dark matter can't be observe directly. The only way to observe it is to create gravitational waves with enough energy, that it radiates dark matter in the form of gravitons or some other kind of particle. Anyway that's my theory on dark matter.

[frankjohnson]

B4 I start watching this one from Dr. Cox, I'm not sure which ONE is the biggest mystery but my top 3 are, what is dark matter? What is dark energy? And what exactly is gravity? ... I'm thinking that if we ever learn exactly what gravity is, the other 2 will fall into place also 🤔. I feel like Einstein's gravity may be as incomplete as Newton's was, compared to Einstein's. I'm no theoretical physist though.😐 2 cents worth...
If I HAD to pick one most mysterious mystery ofall, it would have to be, what exactly is gravity. 🙋My vote cast. And I think that once we figure that out, we would, very soon thereafter, have our way of getting around the universe VERY quickly, if not instantaneously...? 🤷
Navigation will be the challenge, certainly through space, maybe even time.

[grahamf]

When I was at school, we talked about “the fudge factor”. This was the number by which you had to multiply your answer, so that it matched the correct answer at the back of the text book. How do we know that dark matter and dark energy are not simply fudge factors, because our equations are slightly incorrect?

[teddyrwilliam]

Allways enjoy Brian videos very interesting more please

[shadowoffire]

We are at the very beginning of time for the human race. It is not unreasonable that we grapple with problems. But there are tens of thousands of years in the future. Our responsibility is to do what we can, learn what we can, improve the solutions, and pass them on. It is our responsibility to leave the people of the future a free hand. In the impetuous youth of humanity, we can make grave errors that can stunt our growth for a long time. This we will do if we say we have the answers now, so young and ignorant as we are. If we suppress all discussion, all criticism, proclaiming “This is the answer, my friends; man is saved!” we will doom humanity for a long time to the chains of authority, confined to the limits of our present imagination. It has been done so many times before.
It is our responsibility as scientists, knowing the great progress which comes from a satisfactory philosophy of ignorance, the great progress which is the fruit of freedom of thought, to proclaim the value of this freedom; to teach how doubt is not to be feared but welcomed and discussed; and to demand this freedom as our duty to all coming generations.
-richard p. Feynman

I suppose the biggest mystery in the universe depends upon whom one asks the question to or whom is asking the question.

[jasoncox]

I love watching anything about the universe with professor Brian Cox.ive watch of his space programs like wonders of the solar system and wonders if the universe the planets then universe worth watching

[oubliette]

do the numbers change with distance and duration? if the universe were half its current size further back in time and we were there to observe things would it still be 4 percent known 96 unknown?
