Class In Session As Planet X Starts It Off With Our Favorite Dense Objects: 

This is what happens when Two Black Holes Collide.

This is the animation of the final stages of a merger between two black holes. What is particularly interesting about this animation is that it highlights a phenomenon known as Gravitational Lensing.

What is Gravitational Lensing?

Mass bends Light. What? 

Yeah, mass can bend Light. The gravitational field of a really massive object is super strong. And this causes light rays passing close to that object to be bent and refocused somewhere else.

The more massive the object, the stronger its gravitational field and hence the greater the bending of light rays - just like using denser materials to make optical lenses results in a greater amount of refraction.

Here’s an animation showing a black hole going past a background galaxy.

This effect is one of the predictions of Einstein’s Theory of General Relativity

We don’t want to conquer space at all. We want to expand Earth endlessly. We don’t want other worlds; we want a mirror. We seek contact and will never achieve it. We are in the foolish position of a man striving for a goal he fears and doesn’t want. Man needs man!

As I Was Moving Ahead Occasionally I Saw Brief Glimpses of Beauty, Jonas Mekas (2000)

I was laughing so hard that’s why it’s so blurry, but I still kind of like it? I miss these guys and our late night adventures.

Sometimes I want to go up to the people who insist that feminism and progressive values are Ruining Science Fiction and remind them that their genre exists because a teenaged girl was stuck at a house party and decided that inventing science fiction sounded more appealing than yet another tiresome threesome with Lord Byron.

If Earth had Saturn’s Rings

From an excellent post by Jason Davis

From Washington, D.C., the rings would only fill a portion of the sky, but appear striking nonetheless. Here, we see them at sunrise.

From Guatemala, only 14 degrees above the equator, the rings would begin to stretch across the horizon. Their reflected light would make the moon much brighter.

From Earth’s equator, Saturn’s rings would be viewed edge-on, appearing as a thin, bright line bisecting the sky.

At the March and September equinoxes, the Sun would be positioned directly over the rings, casting a dramatic shadow at the equator.

At midnight at the Tropic of Capricorn, which sits at 23 degrees south latitude, the Earth casts a shadow over the middle of the rings, while the outer portions remain lit.
