Can we travel faster than the speed of light⁉️ Brian Cox #science #universe #physics

Can we travel faster than speed of light. Brian Cox explained Albert Einstein theory. Faster-than-light travel and communication are the conjectural propagation of matter or information faster than the speed of light. The special theory of relativity implies that only particles with zero rest mass may travel at the speed of light, and that nothing may travel faster. Related topics

I have heard a few different explanations on the speed of light speed limit but this might be one of the best, short and sweet.

If John Wick was casted in Interstellar.

I find Brian Cox impossible not to like. Am I alone in this?

Blessings! 🙏🏻

The man is so dedicated, he even went to outer space just to film this short.

I don't get the paint throwing example. Why would you see the paint on the wall before it was thrown if you could travel faster than light?

Such a cool kinda guy, I always like listening to his gentle way of explaining

However, there are regions where spacetime is gravitationally warped so as to prevent light from escaping. The inside of black holes break the speed of light.

I think that the current scientists don't dare to contradict Einstein. But one day into future someone will debunk Einstein's theory of relativity. Proving we can travel faster than the speed of light.

It's interesting that in quantum physics, 2 entangled particles, when separated, will mimic each other instantaneously, despite being separated. The 2 most successful scientific theories, quantum mechanics and relativity, are mutually exclusive and incompatible with each other.

Basically, reaction can't happen before action.

Any good equation is only a good interpretation of how we communicate to one another so each has a similar understanding.

[ProPyroPower]

traveling faster than light means youre no longer traveling through time itself..

[wolverinexo]

I think we could probably find a loophole.

[KARANVANIYA]

We can't reverse cause and effect. We only see them in wrong order at FTL speed.

[robertdeen]

If something did move faster than light, wouldn't we never see it?
Just like a plane at Mach+.
The plane will be gone before we hear it.
I think eventually, they'll come up with a way to go faster than light, but it'd only be relative to us, not a person or alien observing it.

Physicist: can we travel faster then light?

"You can't see the back of your own head - unless you're in a *really* small universe"

(Terry Pratchett, I think 😉)

But although I agree with Brian Cox' view seen from Einstein's theory, I have a feeling it actually *might* be possible to go beyond the speed of light.
However that would mean time travel, and since time has a very definite and irreversible direction (i.e. forward), the only way would be to jump ahead in time.
Thát way you can avoid a lot of the causality issues - like going back in time, preventing unwittingly that you could even exist in the present. Which would make you look rather silly indeed.

Not that long ago, people were also convinced we couldn't go beyond the speed of sound - and yet we did.
Since the speed of light isn't infinite, it is reasonable to say it can also be passed.
We don't know yet how, but in theory?... Yes, I would argue it can happen.

You cannot travel faster than the speed of light, otherwise you’ll get a speeding ticket.

It also would require an infinite amount of energy for even a massless particle (ex: photon) to move faster than c (3x10^8 m/s) based on special relativity and E= ymc^2 (where y is the Lorentz factor for speeds approaching c)
