Not enough people talk about the fact that Leonardo da Vinci was gay. Like, he’s literally the father of modern technology and one of the smartest human beings to ever live and I never ever learned in school that he was gay. 

If all the LGBT people are as “DOOMED” as the bible thumpers think we are, hell, at least we’re in good company.

Question: If 2 black holes get near each other, can they then gravitationally pull matter out of the other black hole & back into “normal” space?

The short answer is no.

A black hole (in the traditional sense) is defined as an object that has collapsed so that its radius is equal to, or less than, the Schwarzschild of the object.

What does this mean?

Every object has a Schwarzschild radius; this is the point at which an object’s mass is so compressed that the gravitational influence overpowers the other forces of nature and it collapses to a singularity.

Of course, not every object is massive enough to collapse to its Schwarzschild radius. The Earth’s Schwarzschild radius, for example, is about the diameter of a small marble. If you were to apply enough energy to the Earth and compress its mass to that size, it would collapse to form a black hole. The same is true for humans, except I’d need to compress you to a point some 10-million times smaller than a marble in order to turn you into a black hole.

So, what is special about the Schwarzschild radius? This is the point at which the escape velocity for the object is equal to the speed of light. Obviously, since you can’t travel ,or faster than, the speed of light you can’t get out of a black hole neither can another black hole pull you out.

It’s important to realize that, outside of the Schwarzschild radius (also known as the event horizon), spacetime is normal. You can interact with a black hole in the same ways you interact with any other object of mass.

The hunter’s moon—also known as sanguine moon—is the first full moon after the harvest moon, which is the full moon nearest the autumnal equinox.

A rainbow was caught in the trail of an F-22 fighter jet. This picture was taken by Bernardo Malfitano. The low pressure around the body of the jet caused the water to condense and the angle of the sunlight was just right to make rainbow colors.
