  • I'm not really a physics guy (though i like cosmology), but as far as we know, the Universe is still expanding, at an accelerating rate. So the gravity field is increasing.

    With the volume of current Universe, there should be massive amounts of particles (positive energy) created, even more massive than at the Big Bang inflation.

    Why we don't see that?

    How this could be explained by this theory. Thanks anyone.

  • @ketanovas We sort of do see them. I believe the current dark energy hypothesis explains it best. The particles being created are only 'virtual'. They disappear back into the quantum flux nearly instantaneously. I don't think Inflationary Theory covers this. It's thought to have become an issue after the universe's expansion was great enough that dark energy effects override those of gravity. In areas where gravity is very strong, such as the in galaxies, the universe doesn't expand. The ...

  • @ketanovas ...expansion is between the large areas with lots of gravity. In other words, the space between galaxies is increasing. Not the space within the galaxies. Try searching YT for Lawrence Krauss' 'Life, the Universe, and Nothing'. He goes into some detail about what 'nothing' is to a physicist. It's not really 'nothing'. Sounds confusing, but watch the lecture. Hope it helps.

  • (6,90) They could behave like waves though ! :)

  • Thanks for uploading this :D
