RE: Heating up neutron stars with dark matter

in #steemstem5 years ago

I see, thanks for the clarification. All a big mystery to me, a bit like wizards of old wielding magic but you probably won't see it that way although complex mathematics might as well be spellcraft to those who ain't versed in it. I have read the craziest theories, among others one were , as the concept of time starts with the big bang (there is no framework before that) it would be (in theory) possible that half of everything was shot backwards in time from that moment but on all other accounts i have only read that time points forward only under any circumstance. Even once an article on how some supreme genius had succeeded (probably also in theory and math) to somehow propell data/information to the future but that it wouldn't be possible to do the same backwards either, which in essence came down to time travel might be possible but not to the past
... in theory :) 5am i should probably give it a rest , thanks for the reply

This is correct. Strictly speaking, the "before big bang" is undefined. Note that there are as well alternative cosmologies without a big bang.

Dwarf galaxy problem
The dwarf galaxy problem, also known as the missing satellites problem, arises from a mismatch between observed dwarf galaxy numbers and numerical cosmological simulations that predict the evolution of the distribution of matter in the universe. In simulations, Dark matter clusters hierarchically, in ever increasing numbers of halo "blobs" as halos' components' sizes become smaller-and-smaller. However, although there seem to be enough observed normal-sized galaxies to match the simulated size distribution, the number of dwarf galaxies is orders of magnitude lower than expected from simulation.
