Nothing, not even and including Light

Way cooler than dark matter, is antimatter. Something that we actually know exists.

Gah, why just antimatter? Why not go on with other antiparticles, such as positrons, anti-neutrinos, antiquarks, or even dark energy? I guess we're not sure that dark energy exists though.

All that is exactly anti-matter.

Ah, thank you for that. I'm quite new to the world of complex physics, just a few weeks in.

@Quietus: sorry, I gave the wrong meaning. I asked a friend of mine this weekend, a pulse of light is when it goes on and off, and on single flash is a pulse. A normal laser is continuous, but even if it was a pulsed laser, they just had to say the word 'pulse'. Laser is light anyway, so it might well be laser.
