So by definition your use of the term "dark energy" utterly erroneous and stupid because it could be "anything", including:...
You still do not get it.
The definition of dark energy is that it is the cause of the observed effect. That is the correct and intelligent definition.
We have a couple of good theories about what dark energy could be(and some not so good theories, e.g. look up dark fluid). Further empirical evidence will rule out some of these theories. Eventually the evidence will be strong enough so that a theory will be accepted as the best contender.
P.S. My personal opinion is that it will not be any of the current theories!
What pray tell (physically, as in actual physics) is a "repulsive term"?
Really simple, Michael Mozina: A replusive term is a term that produces a replusive force such as a physically, as in actual physics, non-zero cosmological constant.
Use of ordinary English would be something like "unknown acceleration, or "unexplained acceleration", not "dark energy'.
You would be right if your ignorance of the science had not blinded you to the fact that we do know things about the cause of this "unknown acceleration":
- It is very homogeneous.
- It is not very dense (roughly 10^−29 grams).
- It does not emit light: dark.
- The best theories to explain it treat it as an energy.
So a proper decription would be homogeneous, transparent,
dark energy. But people are lazy so they just use
dark energy.
You created a whole religion out of your own ignorance.
You created your personal religion out of your own ignorance.
Now 70+ percent of the universe is "dark energy" and most of the rest is "dark matter". I guess you guys just don't like to admit that the term "I don't know" is a valid scientific answer. You dreamed up mythical brand of energy that may or may not even exist. You did the same thing with exotic forms of mass that you now call "dark matter". The whole "dark" concept actually relates to your own human ignorance, not any actual property of the matter/energy itself.
Your ignorance is still deep and seems to be increasing
!
The fact is that dark energy and dark matter are scientists saying "we do not know fully
but this is what we do know".
As stated above dark energy is called dark energy because we know things about it (it is
dark and acts like
energy).
Dark matter is called dark matter because it is
dark and acts like
matter. The evidence is that dark matter is made of standard particles like non-baryonic matter. Examples of the standard non-baryonic particles are neutrinos and electrons. The usual particles proposed for dark matter come from extensions of the Standard Model, i.e. not that standard but definitely not exotic, e.g. have negative mass.
) could be a problem of GR on large scales.
