Question

What is antimatter? How it is related to dark energy?​

Answer 1

Answer:

The dark matter left behind is colored blue and is determined by gravitational lensing measurements. ... Antimatter is just regular matter with a few properties flipped, such as the electric charge. For example, the antimatter version of an electron is a positron.

Answer 2

Answer:

Antimatter is the opposite of normal matter. More specifically, the sub-atomic particles of antimatterhave properties opposite those of normal matter. 

Antimatter is just regular matter with a few properties flipped, such as the electric charge. For example, the antimatterversion of an electron is a positron. They both have the same mass, but have opposite electric charge.

Nope. Dark matter and antimatter are two totally different and unrelated things. Dark matter is what scientists have called the mystery of what makes up the “missing” mass of the universe (galaxies should have way more mass than they do in order to retain their shape).
