Special Theory of Relativity
Kuvakäsikirjoitus Teksti
- 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.
