We’ve observed several of these objects as close as 3000 light-years away, and there could be up to 100 million small black
holes
just in the Milky Way galaxy.
Despite their large mass, stellar black
holes
only have a radius of around 300 kilometers or less, making the chances of a direct hit with us miniscule.
Still, the combination of how small they are and how vast the galaxy is means that stellar black
holes
don’t give us much to worry about.
But we still have to meet the second type: supermassive black
holes.
These giants have grown to immense proportions by swallowing matter and merging with other black
holes.
Unlike their stellar cousins, supermassive black
holes
aren’t wandering through space.
But before we judge them too harshly, black
holes
aren’t simply agents of destruction.
Far from being shadowy characters in the cosmic play, black
holes
have fundamentally contributed in making the universe a bright and astonishing place.
We then created holes, or apertures, that would lock in the rays of light and heat, distributing those silkworms on the structure.
But I think that's an Orwellian way of describing black
holes.
But if you record the voices of herders who carry spears and often hurt elephants in confrontations at water holes, the elephants will bunch up and run away from the hidden speaker.
Now, I know what you're thinking: "I know what a mole is, it's a small furry creature that digs
holes
in the ground and destroys gardens."
And they prefer crevices and grooves and holes, where they will be safe from being trampled or eaten by a predator.
I study blazars, supermassive, hyperactive black
holes
that sit at the centers of massive galaxies and shoot out jets nearby those black
holes
at speeds approaching the speed of light in a process we are still trying to completely understand.
What particle physicists are all desperately hoping for are signs of new particles, micro black holes, or maybe something totally unexpected emerging from the violent collisions at the Large Hadron Collider.
They were able to think outside the box because their box was full of
holes.
Eventually, the universe will run out of gas to form stars, and the stars themselves will run out of fuel and burn out, leaving the universe with only black
holes
in it.

holes
will evaporate, leaving a universe that is completely cold and empty.
1.3 billion years ago, in a distant, distant galaxy, two black
holes
locked into a spiral, falling inexorably towards each other and collided, converting three Suns' worth of stuff into pure energy in a tenth of a second.
I mean, you know, they're black
holes.
And on September 14 of 2015, just days after the detector had gone live, the gravitational waves from those colliding black
holes
passed through the Earth.
Allan Adams: So that's my very good friend and collaborator, Scott Hughes, a theoretical physicist at MIT, who has been studying gravitational waves from black
holes
and the signals that they could impart on observatories like LIGO, for the past 23 years.
For example, listening to gravity, just in this way, can tell us a lot about the collision of two black holes, something my colleague Scott has spent an awful lot of time thinking about.
SH: If the two black
holes
are non-spinning, you get a very simple chirp: whoop!
Two black holes, the densest thing in the Universe, one with a mass of 29 Suns and one with a mass of 36 Suns, whirling around each other 100 times per second before they collide.
Here's my colleague and one of the key members of the LIGO collaboration, Matt Evans, my colleague at MIT, addressing exactly that: (Audio) Matt Evans: The kinds of stars which produce the black
holes
that we observed here are the dinosaurs of the Universe.
They're these massive things that are old, from prehistoric times, and the black
holes
are kind of like the dinosaur bones with which we do this archeology.
The teeth of those ancient humans were riddled with
holes.
Ancient humans even made rudimentary drills to smooth out the rough
holes
left behind and beeswax to plug cavities, like modern-day fillings.
The more knowledgeable we become, the less likely we are to have invisible
holes
in our competence.
