Default 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.
