Why is dark energy so mysterious? Because we can't measure it directly, we don't even know what it is made of, then formulating experiments to detect it and study its very nature is really challenging. Also, cu
“Everything you can see, everything you feel, everything you’re made up of, only makes up 5 percent of the universe, and the rest is this dark stuff.” “The big thing about it is that we can’t see it; it doesn’t interact with light,” says Ethan Brown, an Assistant Profess...
Dark energy has been described by some as having the effect of a negative pressure that is pushing space outward. However, we don’t know if dark energy has the effect of any type of force at all. There are many ideas floating around about what dark energy could possibly be. Here are ...
Shedding light on dark energy has been a bit of a challenge for today's astronomers. What dark energy actually is goes beyond our present scientific understanding. We know with some certainty that dark energy exists; we know how much of the universe is made up of it; we know the influence...
Why is dark energy so mysterious? Because we can't measure it directly, we don't even know what it is made of, then formulating experiments to detect it and study its very nature is really challenging. Also, current observations disagree with the value of the Hubble rate at the present ...
Why is the sun a source of non-ionizing radiation? Where does the energy in fission come from? Where does dark energy come from? What is dark energy made up of? What is nuclear energy? What is the basic unit of energy? What is the source of a magnetic field?
Unknown physics may help dark energy act as 'antigravity' throughout the universe What is dark matter? Dark matter is an invisible, mysterious substance that makes up more than 80% of the matter in the universe — but scientists aren't sure what it is. ...
By modern estimates, the universe is only about 5% regular matter and energy and about 27% dark matter, or more than five times as much. The remaining 68% of the universe is thought to be dark energy—a topic for another day. Credit: NASA's Goddard Space Flight Center The fact ...
Dark energy may be an inherent feature of the universe, or it could be something related to new and unknown particles or forces. It could also be a hint that Einstein’s theory of general relativity is not a complete description of gravity. ...
What is Dark Matter Made of? Keep in mind that dark matter is a theory. As telescopes got bigger and we observed more of the universe, we realized that there’s far more gravity in the universe than can be accounted for. What’s creating it? What is this strange, unseen, powerful stu...
