So to be serious for a moment, now we are here:
- We don't know what dark matter is (it's undetectable matter that increases the mass of galaxies).
- We don't know what dark energy is (it's unexplained force that is the opposite of gravity, pushing galaxies apart).
- We are still investigating antimatter (which "annihilates" with normal matter to create light).
I want the scientists to decipher the mysteries of the Universe as soon as they can, preferably in my lifetime.
Right now I wonder, can light be split up into matter and antimatter?
