We don't understand why the fundamental constants of nature possess the values they are doing. Developments in particle physics advise some exciting approaches these inquiries might be answered; the obstacle is to search out experimental exams on the Tips.
Most galaxies remain generating new stars, but numerous Other people have already fatigued their source of fuel. 30 billion yrs from now, galaxies will be much darker and filled with lifeless or dying stars, so there will be considerably less planets able to supporting life mainly because it now exists.

This theory was born with the observation that other galaxies are shifting far from our individual at fantastic pace in all directions, as though that they had all been propelled by an ancient explosive pressure.
Distant radio galaxies, on the other hand, appear to get elongated and sometimes irregular structures. Additionally, for most distant radio galaxies, unlike those close by, the distribution of light tends to be aligned Using the pattern of the radio emission.
