What percentage of the universe is matter?
It is believed that about 4% of the mass in the Universe is normal matter. About 23% is dark matter (matter of unknown composition), the remainder being something even more mysterious called dark energy. I suggest searching the Wikipedia for "dark matter" and "dark energy", for more details about both.
What force do scientists such as Saul Perlmutter believe is counteracting gravity and allowing the universe to accelerate the rate of its expansion?
Dark energy is the term to refer to the force that is causing an expansion of the universe to accelerate. It is estimated that the universe is 68.3 percent dark energy, 26.8 percent dark matter, and 4.9 percent ordinary matter.
Is the universe matter?
The Universe contains matter, energy, dark matter, dark energy, empty space - and of course, lots of structures made up of those.The Universe contains matter, energy, dark matter, dark energy, empty space - and of course, lots of structures made up of those.The Universe contains matter, energy, dark matter, dark energy, empty space - and of course, lots of structures made up of those.The Universe contains matter, energy, dark matter, dark energy, empty space - and of course, lots of structures made up of those.
Could astrophysics's dark energy simply be the invisible alternate universes created and inhabited by the what would have beens of all the choices we make during our lives?
A very deep question, but dark energy and dark matter are really only theories that attempt to explain the so-called "missing" energy and matter in the universe. Scientists first proposed these ideas because they noted the universe was expanding too rapidly for the matter that is within it. Dark matter and energy do not interact (or have minimal interaction) with normal energy and matter. So you could have dark matter flowing through you right now. Weird. In any case, if the energy and matter do not interact with normal matter and energy, how could they be alternate universes?
Which is thought to be more prevalent in the universe dark matter or dark energy?
Dark energy. The current estimates for the distribution of mass/energy in the Universe are approximately: 68% dark energy 27% dark matter 5% baryonic (i.e. "normal") matter
Can Astronomer's directly detect dark energy and dark matter?
Dark matter and dark energy have NOT been detected yet, so any ideas about detecting dark energy and dark matter, whether it be directly or indirectly, is speculation for now.
Is there dark matter inside a black hole?
It is currently unknown as scientists do not even know what dark matter is.
What kind of matter dominates in the universe today What kind dominated immediately after the big bang?
I think the question is a bit mixed up, but I think this is the answer. Scientists talk about "mass-energy" as a unified thing. Just after the Big Bang "energy", in the form of radiation energy, was dominant. However, today it seems that "mass" is the dominant form. In other words, "matter" now dominates the Universe. There is the complication of "Dark Matter" and "Dark Energy". Cosmologists still don't really know what these are. So that puts some uncertainty into this discussion of matter and energy. Some scientists believe that it is now "energy" that dominates, because of the discovery of Dark Energy. (Also, cosmologists think that both "matter" and "anti-matter" were created, but that there was a slight imbalance in favour of matter and the anti-matter seems to have been destroyed, leaving just "matter".)
How many dark matter can scientists see?
By definition, "dark" (look up what that word means!) matter can not be seen.
Where would you find visible energy and invisible matter in universe?
A good example of visible energy is found in the stars. An example of invisible matter is the "dark matter" that scientists believe surrounds galaxies. So, one answer to the question would be "in and around galaxies".
Why dark energy and matter does not obey standard physics and chemistry?
Standard physics and chemistry are based on the energy and matter that we know. We do not know much about dark energy or dark matter, but only that it may exist.
Compare the amount of visible matter in the universe with the total amount of matter and energy?
4% Visible Matter (Atoms) 23% Dark Matter 73% Dark Energy
