It is, it must be stressed, just a theory.
It's possible that smarter people than me in the comments will explain why this is wrong.
However, it does neatly explain to me why time dilation happens, and why reality has a speed limit, which I find quite appealing.
In fairness, perhaps the only way to test it would be to try to go faster than the speed of light, and we have never gotten close to that speed.
The fastest a human has ever gone is 11,083 meters per second.
when NASA astronauts returned in a spaceship from the moon, it would require incredible amounts of energy to travel sea from our perspective.
If it is true though, it would provide firm evidence that our universe really was hyperbolic in nature, and sadly quash any hope of us travelling backwards in time at any point, so sorry time travel fans.
But at least we can console ourselves that although we probably can't travel to the past,
travelling through shortcuts to the future is definitely within the realms of possibility.
In this channel, we've talked a lot about time.
As black holes warp space around them, we've learned that time slows down.
We've discovered the time-influencing effects of gravity, and even how the James Webb telescope can peer through time to the distant past by taking advantage of the fixed speed of light.
All this makes sense so far, but what actually is time?
You can't taste it, touch it, or feel it.
Yet time has an unstoppable influence on us, and is pushing us forward whether we like it or not.
Doesn't something that impacts everything we do deserve some additional understanding?
I'm Alex McColgan and you're watching Astrum, and while this is an area that scientists have many theories about, I'd like to share with you today one model that might help you understand this mysterious concept that is ticking all around us.
By the end of this video, we are going to have a possible explanation for why time slows down as velocity increases, and why shapes warp when undergoing velocities close to the speed of light.
This video is a collaboration with my brother, based on recognised scientific theory, where we have taken scientific concepts and combined them into something you may not have seen before.
