What is the nature of the dark energy?

Answer 1

The whole point of dark energy is that we can't see it. We have deduced that it must exist, because the amount of energy we can see is less than the total amount which we have calculated there ought to be based on our current theories about the nature of the universe.

The first thing to realise about this is that we therefore don't know for certain that dark energy exists at all - we might realise at some future point that our current theories about the nature of the universe were incorrect.

The second thing to realise is that by dark we pretty much mean "unknown". Therefore if we knew what the nature of it was, it wouldn't be dark any more......

Answer 2

The exact nature of this dark energy is a matter of speculation. It is known to be very homogeneous, not very dense and is not known to interact through any of the fundamental forces other than gravity. Since it is not very dense—roughly 10−29 grams per cubic centimeter—it is hard to imagine experiments to detect it in the laboratory. Dark energy can only have such a profound impact on the universe, making up 70% of all energy, because it uniformly fills otherwise empty space. The two leading models are quintessence and the cosmological constant.

Answer 3

Eleven answers and they are all wrong. There is no such thing as dark energy. It is dark matter, a substance that can't be seen because it reflects no light. It was proposed that 90% of the matter in the universe fell into that category, scientists felt that this matter should have enough gravitational influene to slow down the expansion of the universe, but it is not happening. They then proposed that there must be a source of dark energy causing the epansion, but this idea led nowhere.

Answer 4

Totally and absolutely unknown at this time. A few scientists are working to somehow relate it to what's commonly known as 'inflation' which was a brief period immediately after the Big Bang when universal space expanded faster than the speed of light. It's also known that at the quantum level what we call empty space is actually seething with energy. Maybe dark energy originates in that quantum realm too.

Answer 5

It depends on the intensity of the dark energy

Answer 6

No one has a clue. Be the first to come up with a provable answer and you'll be handed a Nobel Prize for Physics. Get to work. Immortality awaits you.

Answer 7

you have 2 really good answers here and I cant think of anything else other than "all returns to light". As the light is now shining on the many atrocities that are happening in our world there may soon be nowhere for it to be.

Answer 8

Answer that and a Nobel Prize is yours.
One of the reasons that science is fun is that there are loads of unknowns just waiting for someone to understand

Answer 9

to keep light energy company

Answer 10

You know, if it wasn't Scientists coming out with this stuff, it would be called religion!
