I understand that, and will take note on that. What I meant was that the difference is negligible small. What happens to these 61,605,000 j/kg if this small object annihilates with another small object of antimatter, and their masses converts into electromagnetic radiation? Gone with the...

Yes. And as times goes by this small little difference grows, and turns into a huge difference. If I were a salesman of universes, I would take different prices for universes with different overall energies. How do I sell universe A and B, what do I tell my customers? “Well universe A...

Imagine a universe A, containing only two identical heavy planets situated at an almost infinite distance from each other. Imagine another universe B, containing only two identical lighter planets situated at an almost infinite distance from each other. In both cases the gravitational...

Increased gravitational PE between the planet and the box, yes. When the box is gone, or part of it, what happens to the PE? Who can now benefit from the PE?

The boxes is not isolated systems themselves, so the energy contained in the boxes are part of the energy of the systems. When the experiment starts there is a difference between the energy in system A and B, because the planet in system B has more mass. That difference should always be the...

If we think of two isolated systems, A and B, existing side by side, the proportion of the energy between those systems should always stay the same. Here is a thought, that I would like some comments on: System A contains a planet, and the advanced civilisation on this planet, have created...

Hi. I am a little confused about this: If I throw a stone straight upwards from the surface of the Earth, with the escape speed of 11,2 km/s, assuming that no air or other particles gets in the way, and waited for a very, very long time, the velocity of my stone (and the Earth in the...

Thanks for your reply! Since the star and the planet has a very small effect on each other after all, during very long time, they would be drawn towards each other because of gravity, stronger and stronger, resulting in a big collision, that would result in more heat in that universe. But...

Hi. Imagine a closed physical system (a universe) with only one star like our Sun, and one planet like our Earth, but so far away from each other, that the gravity from both matters only has a very small effect on each other. There is a (almost maximum) gravitational potential energy...
