Question: If 2 Black Holes Get Near Each Other, Can They Then Gravitationally Pull Matter Out Of The

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.

Galaxy-Inspired Bath Bombs

Galaxy-Inspired Bath Bombs

These galaxy-inspired creations are designed by licensed cosmetologist Heather Mcginley, who studied all natural and organic ingredients for about 10 years before deciding to make her own non-toxic products. When placed in water, the powdered balls unleash a delightful fizz and bubbliness, while also releasing soothing aromatherapy scents and turning your bath an exciting range of colors.

I remember first learning that you can cry from any emotion, that emotions are chemical levels in your brain and your body is constantly trying to maintain equilibrium. so if one emotion sky rockets, that chemical becomes flagged and signals the tear duct to open as an exit to release that emotion packaged neatly within a tear. Everything made sense after learning that. That sudden stability of your emotions after crying. How crying is often accompanied by the inability to feel any other emotion in that precise moment. And it is especially beautiful knowing that it is even possible to experience so much beauty or love or happiness that your body literally can’t hold on to all of it. So what I’ve learned is that crying signifies that you are feeling as much as humanely possible and that is living to the fullest extent. So keep feeling and cry often and as much as needed
