Finally! A black hole that you can visit and survive!
Want a trip through a black hole without having to experience that pesky death? You’re in luck. There’s a special kind of black hole that’s not just survivable, but might get you to another time, or another universe.
Black holes are, traditionally, the scariest things in the universe. Huge, mysterious, inescapable, they wander through the universe and eat everything that gets too close. “Too close” is defined by their event horizon. This is the point at which they go dark, because it requires so much energy to escape them that not even light can get away. Since not even a photon can cross the barrier, no event that happens inside the horizon can ever have an effect on people outside.
Unless, something very odd was going on in the center of the black hole. Most black holes spin - this is something that was discovered way back in the 1960s by physicist Roy Kerr. It wasn’t exactly a shock, because most of the material that collapses into a black hole was already spinning. Sometimes, however, the spin on Kerr black holes goes a little above and beyond. Ever spun a glass of water, or soda bottle, so that the liquid inside swirls? Sometimes, if you spin it enough, the liquid actually parts, leaving a clear center and a spinning ring of water around it. The same kind of thing can happen in Kerr black holes. Instead of a singularity at the center, there’s a ring. And you can go through the open portion of that ring without touching the gravitational crush.
What’s on the other side? A lot of people have wondered. Some people think that these kind of black holes might be our key to time travel. They might be wormholes that let us hop between different points of the universe. Or they might be portals to different universes entirely. First we’ll have to find a few, and then we’ll need a few volunteers to go through. Preferably ones that haven’t seen Event Horizon.

It is my love of sci-fi, not science, that forced me to reblog.
Another time? Another universe?
you know what to do
I couldn’t get this .gif to work on my phone
The overworked Chinese laborer who made this phone after being kept awake for 46 hours, delirious with sleeplessness and her eyes stinging due to the toxins in the air around her would be rolling on the floor right now.
Mtumbe Ngoube, the 11 year old African girl who is being kept as a slave in the Congo, who spends all hours of the day digging up the minerals necessary to make that phone would be clapping for you right now if she had any arms. The militia cut them off.
THE PHONE WAS ALREADY BROKEN THE PHONE WAS ALREADY BROKEN STOP TRYING TO GUILT TRIP ME ITS NOT EVEN WORKING also how does the slave girl dig with no arms

remember when dirk drew this
reminder that this whole deal right here is 100% canon no joke
preparing for interviews. I believe they were masked during this particular one, but I wanted to draw their expressions.
sooooo, i got these today :)
Totally missed this earlier! Sorry!! Glad you like them though :)

Best kid ever.
Finally a kid doesn’t have to be saved
i made a new one bc the last one is hilariously outdated
