No. It is the mass that stays the same everywhere in the universe.
Energy and matter(mass) are not the same! Energy = mass x c^2 !
Mass is the quantity of matter. Even though matter contracts the mass remains constant.
Yes, matter and energy make up the physical universe. Matter refers to physical substances with mass and volume, such as atoms and molecules, while energy is the capacity to do work or produce motion. Together, matter and energy are the fundamental components that comprise the observable universe.
matter has mass and takes up space.matter

It depends on the context. One would be the mass.
No. It is the mass that stays the same everywhere in the universe.
All matter in the universe.
Only if your the comic book guy.
Thorium constitutes about 4E-8% of the visible baryonic matter of the universe by mass. Visible baryonic matter is about 4.9% of the total mass of the universe, as per the latest estimates. So the mass-percentage of thorium in the universe would be 4E-8 x 0.049 = ... very little.
Atoms make up most matter around us. In the Universe in general, it seems that atoms make up about 4% of the mass of the Universe. The remainder of the Universe mass is dark matter and dark energy - both of unknown composition.
The evidence for the existence of dark matter in the universe includes the extra mass of Galactic clusters discovered by Fritz Zwicky, and the spinning galaxies which rotate at the same speed as discovered by Vera Rubin.
Matter and energy, which according to E=mc2, are interchangeable.Another answer:To be technically correct, we are talking about mass, not matter. Einstein's equation e = mc2 does not necessarily mean that mass and energy are interchangeable - it means that they are the same thing. Mass is energy, and energy is mass. Its not an issue of converting from one to the other - its a matter of them being the same thing - just different frames of reference.
The mass of an object remains the same everywhere in the universe.
Energy and matter(mass) are not the same! Energy = mass x c^2 !
