There are two statements that sound simple, yet contain a richness of physical understanding in my Special Theory of Relativity.
They are as follows: (1) nothing travels faster than the speed of light, which is constant for everyone; and (2) the laws of physics are constant for everyone, regardless of whether they are in motion or not.
Now we know that the universe's maximum allowable velocity is the speed of light.
Exactly. One would expect the Flash to be able to break through this barrier as his speed increases, but that's not going to happen.
Newton's 2nd Law of Motion dictates that the faster he accelerates, the more difficult it gets for him to accelerate further..
Additionally, as the Flash approaches the speed of light, his mass increases as a result of Newton's 2nd Law of Motion. As a result, going faster becomes more difficult for him.
Yes! Finally, you understand. I'll close with one last example.
See you in a few years.
Consider the case of identical twins. Then, one of them promises his other twin that he will return from a trip to a faraway planet at the speed of light.
Good luck!
I'm stumped...but I think I know what it is. Because they traveled at the speed of light, the older twins are older than the younger ones.
Which of the twins do you think will be younger than the other?
Hey there, dude. I've come back! Woah! You appear to be much older than you really are.
Wow! You got it right! Time slowed down for him because he was traveling at the speed of light.
Yeah. Time seemed so slow here on Earth while you were travelling there in space.
