waleed123: No, He doesn't fuse to H... When heat and pressure surround many H atoms, they collide, making He, and the He makes Li, Be, and so on. And when two atoms fuse, it creates the energy that feuls the star.
Waleed, helium dosnt fuse into hydrogen. Hydrogen fuses into helium, helium fuses into another element, and so on, til lit hit iron, then the star gos Ka-boom. If big enough iron core it might maske a black hole.
star core makes helium that fuses to hydrogen that burns up
Zaddy23: Another theory, is that, stars burn hydrogen to fuse and make energy, but after billions of years, that energy gets used up. And there's nothing else to fuse, and stars burn out. Leaving an empty, cold, dark place... Lol And one more theory thats like those two, exept, at the end, galaxies and everything start accelerating back to a center point, called the big crunch...
Zaddy23: ell, there'a a bunch of theories... One of them, is that the universe is expanding, and everything is getting farther away from us, and from anything else in the universe. Then after a few billion years, the universe will be an empty, cold, dark place.
When a star goes nova, I noticed it explodes along lines commonly 45 degrees away from eachother, either straight up, up-right, right etc. Any idea what causes this? Also, what exactly causes the universe to "die" eventually?
Doolittle, just interpret it the way you want to. If you agree with Metaforce, then by all means do so. I made this save with my own interpretation, aka the timeline, but if someone else sees it in a different way, that's fine. Thank you and enjoy!
metaforce is right, gravitons were present at the big bang, creating gravity
