It seems that as Dark Energy increases, Dark Matter decreases astime goes on
After calculating the amount of Dark Energy there was in the past vs.
Dark Matter, that galaxies in the early universe had not only had less Dark Energy (as expected), but they also had more Dark Matter (not expected). Scientists thought that Dark Matter should remain more or less the same in magnitude, since it's supposedly a type of matter, while the Dark Energy component grows. But they're finding that the Dark Matter component might have been higher in the past than it is now. If that is the case, then Dark Matter cannot be a type of stable particle, it is just another form of fleeting energy like Dark Energy is. In fact, it would mean that theories such as Dark Fluid would be right, i.e. Dark Energy and Dark Matter are just two sides of the same coin, and when one goes down, the other goes up, and vice-versa. It also puts a kibosh on particle physics theories like Supersymmetry, as we'll never see superpartner particles like neutralinos or photinos, as the Standard Model is all that is necessary to explain the universe as it is now. With the Standard Model, the vacuum energy is all that is necessary to create the pushing effect of Dark Energy, and similarly the same vacuum energy would be all that's necessary to create the pulling together effect of Dark Energy.
