1. ### What is energy?

Isn't this the theory development one? sorry I'm getting tired. I think I'll just stick to talking in my own thread
2. ### What is energy?

Well I think Gravity is defined by time. What do you think of this If electron A exists only in probability to be found 50% of the time on the left of a line and 50% on the right of a line. Then just like everything in our universe time is relative, so if time is running at a higher frame...
3. ### What is energy?

In post 42 you say mass and energy are somewhat interchangeable In your Equation for kinetic energy you say mass must be non zero to travel the speed of light. But we actually know light has mass, if you put it into a box with perfect mirrors the photon would add mass to the box. Therefor We...
4. ### What is energy?

if the photon interacted with your skin didn't it have mass? If a photon is kept in a box of perfect mirrors, it has mass.
5. ### What is energy?

and to zoobyshoe, I think without mass motion can't give energy
6. ### What is energy?

So question from post 35, it would violate that equation, and the uncertainty principle? Also conservation of energy right?
7. ### What is energy?

Doesn't E=mc^2 say that something which has mass can't travel at the speed of light???
8. ### What is energy?

But a photon has E, E by definition represents all forms of energy does it not?
9. ### What is energy?

It wouldn't violate E=mc^2 ?
10. ### What is energy?

No I am asking, If you knew Where a photon was at a given time, and knew it's momentum to be c would that violate the laws of physics, other than the uncertainty principle
11. ### What is energy?

What are the observations of it's speed, I ask you ,You know it must exist somewhere in there in probability. So If it were possible, what would your calculations show, objevtively
12. ### What is energy?

ok sorry, got ahead of myself. But if you could measure that photon's momentum and place at the same time without interacting with it. Would it's M make it an impossibility?
13. ### What is energy?

If motion is energy then a PARticle of light travelling light speed would have infinite energy???? I think I just figured out why there is an uncertainty principle. Because if you know the exact position of that photon and know its exact speed(light) then it is disobeying the laws of...
14. ### What is energy?

photons are both a particle and an energy wave. Depending on the circumstances
