In the current paradigm of cold dark matter, then yes, dark matter is everywhere in space, and can pass through and inside your body. It must be so weakly interacting with normal matter that there is nothing to stop it. However, the answer to whether there is any dark matter inside you now turns out to depend strongly on what that dark matter is. Dark ...

Dark energy is a response of the GRT followers to that they can't explain the shape of galaxies. The Heaviside style GEM does indeed give the correct shape without adding a fix to nature to make the equations work.

The FLRW energy equation $$\left(\frac{\dot a}{a}\right)^2~=~\frac{8\pi G\rho}{3c^2}$$ gives a solution for the scale factor $a(t)~=~a_0(t)exp(t~\sqrt{\frac{8\pi G\rho}{3c^2}})$. We have here that the density $\rho$ is the density of energy in the vacuum of space. This is most often thought of as due to the zero point energy of quantum mechanics. The ...

I think there is no common explanation for this. Some people try to build some theories about that, but nobody can prove them. Every "beyond standard model" theory probably has it's own explanation for dark energy. One of them is still pretty interesting at least. I remember that Stanley Brodsky talked about that during the NED/TURIC meeting in 2014. He ...

To start with, the cosmological constant, vacuum energy, and dark energy are mostly used interchangeably in cosmology. This is because the cosmological constant is observationally indistinguishable from vacuum energy by the Einstein field equations. The term "dark energy" was, as far as I am aware, introduced when the expansion of the universe was observed ...
