In physical cosmology, astronomy and celestial mechanics, dark energy is a hypothetical form of energy that permeates all of space and tends to increase the rate of expansion of the universe. Dark energy is the most accepted theory to explain recent observations and experiments that the universe appears to be expanding at an accelerating rate. In the standard model of cosmology, dark energy currently accounts for 73% of the total mass-energy of the universe.
What else can I help you with?
Can dark energy cause a supernova?
No. While scientists do not really know what dark energy is or how it works, they do know that its effects are only noticeable across great distances of hundreds of millions to billions of light years, the sorts of distances between galaxy clusters. An individual star is much to small for dark energy to affect its internal dynamics.
Is there dark matter inside a black hole?
It is currently unknown as scientists do not even know what dark matter is.
If there are the areas of 'nothingness' in outer space what actually is there?
These areas of "nothingness" are mostly empty space, with a few stray atoms and other particles. There is also evidence for something called dark energy, which is somehow connected to the expansion of space. Scientists still do no know what this dark energy is.
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.
How are stars dust and gas similar to dark matter?
The only similarity we know of is that they all seem to interact with gravity. Aside from that, scientists do not know what dark matter is.
What force do scientists such as Saul Perlmutter believe is counteracting gravity and allowing the universe to accelerate the rate of its expansion?
Scientists like Saul Perlmutter believe that dark energy is the force responsible for counteracting gravity and driving the accelerated expansion of the universe. This mysterious form of energy has a repulsive effect and is thought to make up a large portion of the universe's energy density.
Scientists are working to harness the geothermal energy?
I am a chemist, and I don't personally know of any scientists who are doing this. but some scientists I know are worried about this method. well as you probably know there are pro's and con's of using hydrothermal resources.
Can dark matter be harnessed as an energy source?
Currently, dark matter cannot be harnessed as an energy source because it does not interact with light or other forms of electromagnetic radiation. Scientists are still studying dark matter to understand its properties and potential uses in the future.
Dark energy is an unexplained force that is causing?
Dark energy is a mysterious form of energy that is causing the accelerated expansion of the universe. It is thought to make up about 68% of the total energy content in the universe, but its exact nature and origin remain unknown to scientists.
Why is dark energy so weak?
We do not know what dark energy is, so we can only theorize about its sources. However, if dark energy were much stronger than current observations estimate, life would not be possible. Therefore, we can say dark energy is weak in our Universe, because our Universe is capable of supporting life.
The exhaust from a car contains energy that cannot be used. scientists often refer to this energy that cannot be used as waste energy?
i don’t know
Is space formed by dark energy?
We do not know. Certainly current THEORIES suggest that dark energy is causing the universe to expand at a faster and faster rate. Its existence is postulated to explain why we can observe that the universe is expanding at an accelerating rate. However, we do not know what dark enery is (if it exists).
