The second largest component of the universe is dark matter. The truth is, we understand little of what it is, and more of what it is not.

What is Dark Matter? The second largest component of the universe is dark matter. The truth is, we understand little of what it is, and more of what it is not.

From dark energy and string theory to the end of the Universe, these are the unanswered cosmic conundra that are still baffling scientists.

If an alien in a galaxy 65 million light years away is looking at us through a telescope right now, then they are looking at dinosaurs.

If aliens are looking at us…

Funny pictures about If aliens are looking at us. Oh, and cool pics about If aliens are looking at us. Also, If aliens are looking at us.

Our Milky Way Galaxy: A Traveler's Guide (Infographic) Our home in space is a vast galaxy containing 400 billion suns, at least that many planets, and a black hole at the center.

An almost-equal mix of matter and antimatter annihilated away in the early Universe, giving rise to just a slight excess of matter over antimatter.

Where Is The Cosmic Microwave Background?

As the Universe expands and cools, unstable particles and antiparticles decay, while matter-antimatter pairs annihilate and photons can no longer collide at high enough energies to create new particles.
