@notenoughspacetalk: Join Brian Cox as he unravels one of the most mind-bending ideas in physics — what really happens at the speed of light. ⚡ In this fascinating talk, Brian explains how time itself slows down as you approach light speed, and at the speed of light, it effectively stops altogether. He explores how this bizarre consequence of relativity reshapes our understanding of motion, time, and the fabric of reality itself. With his signature wonder and clarity, Brian reveals why the speed of light isn’t just a number — it’s the ultimate speed limit of the universe. #BrianCox #SpeedOfLight #Relativity #TimeDilation #PhysicsExplained
Hypothetically if it was possible to travel 99.9% of the speed of light we could time travel into the future as the time of the traveller would be much slower compared to earth.

Wait if you have a machine that create a gravity 0 field around you you can do it no? you can speed to the speed of light 🤔

The speed of light is the clock speed of the processor that is determining our reality. As you approach the speed of light the fps of reality grinds to a halt. You experience no time. At much slower speeds you experience time at increasing rates. If you could stop physically in the universe you would experience time at the highest rate,

But then that means light years do not actually exist theyre just a way for us to percieve huge distances? Because a light years definition is that something going at the speed of light takes a year to reach from point a to point b but youre saying it would be like you wouldnt percieve time. Are you saying that u just wouldnt percieve it somehow or that the tile inbetween actually doesnt exist?

we need to travel at the speed of darkness it's faster than light

What about an exotic matter? Can exotic matter go in speed of light?

Just a quick one just to clarify you can travel at the speed of light if you have no mass but light is affected by gravity whether it be Earth gravity or a black hole's gravity , i thought gravity only affects mass.. therefore light has some sort of mass possibly? so you can,can you travel at the speed alight with mass. ? be it very little mass..YES..NO . Please enlighten me please further my education . Thankyou

so is "energy" completely quantifiable... are you/we sure
if the big bang came from "nothing" ... cant "something" contain more than we know

Makes me believe that light is the canvas and physical reality if moving “through it”

🤔 so you need mass to be like weight and apparent weight same only different 😈

#Darwins Evolutionary Theory Overlooks Any Higher Order. Science Chooses Not To Consider Any Other Order. It Is Incorrect To Theorise That Energy Is Followed By Matter Is Followed By Consciousness. Now Consider That Consciousness Is Followed By Energy Is Followed By Matter. Only Form Changes. This Is Our Tiny Conscious Universe.

well. you are wrong, you don't even get relativity correct or comprehend light has mass because it's matter. so yeah the speed limit of electron glow is just like the sound barrier and what you call time dilation drag is drag on photon. nothing more
