What keeps space empty?
Here we know about What keeps space empty really let’s know…
Space is not empty. A point in outer space is filled with gas, dust, a wind of charged particles from the stars, light from stars, cosmic rays, radiation left over from the Big Bang, gravity, electric and magnetic fields, and neutrinos from nuclear reactions.
As the book “Nothingness: The Science of Empty Space” by Dr. Henning Genz describes, space is also filled with two things we can’t directly detect: dark matter and dark energy.
Even if all these things could be removed and blocked out from a certain region of space, there would still be three things we could never remove according to Dr. Genz:
(1) vacuum energy,
(2) the Higgs field
(3) spacetime curvature.
