I created this thread mainly becuase I dont know much about these things but what are (ill put what I know next to them)-
Dark matter(a theoredical particle that allows for computer simulations of galazies to work, and can go thorugh all matter wihtout effect.)
Dark energy(anohter part of the dark matter theory that is basically invisible energy)
Anti matter(somehting that was around at the start of the universe that when it touches matter 'vapourises it' ans was blamed for Tunguska)
Phantom energy(I think this is the same as dark energy???)
