Bobbywhy,
I did not find any restrictions in the forums guidelines in regards to the type of questions I was asking.
If my posting is inappropriate to the forum, I apologize.
I was looking for a lively dialog on the subject, with those who have a deeper understanding of GR, given the current...
Well, neutrinos fall into the category of hot dark matter. Their relativistic speeds and mass characteristics do not fit the models of cold dark matter. With cosmology defining the percentages of hydrogen, helium, and other trace metals at the Big Bang, and all other nuclear reactions within...
Well, not sure with your answer. If space between galaxies can expand outside the influence of matter, can it not contract or warp in the presence of matter. Isn't that what a gravitational field is compared to, a warping of space-time.
Most physicist's believe space is not empty, but a foaming...
It would be even more interesting if dark matter and dark energy, are related by the same property of space. Mass changing the properties of space in a way we observed as dark matter, and space outside of matter interactions, observed as an accelerating universe, we label as dark energy.
Ok, we have all read that space is expanding, especially in low mass areas between galaxies, as described by GR.
And that mass bends space, like seen in gravitational lensing.
My question is whether on larger scales and masses, like on the size of galaxies, space itself is warped?
The properties...
