Video—What if there was a black hole in your pocket?
Could you survive being close to a black hole the size of a nickel? Seriously though, how grisly would your death be and what would such a phenomena mean for the future of the Earth?
A new video from the folks at Kurz Gesagt posted July 16 tries to answer those questions with some helpful animations. The video explores a few different assumptions, as the impact of the black hole would depend on whether its size was based on the mass or width of a nickel. Either way, if a black hole developed anywhere near you, you would certainly die, but the impact on the Earth would be drastically different.
The video argues that a black hole with the mass of a nickel would radiate away all of its mass almost instantly, leading to an explosion about three times bigger than the atomic bombs dropped on Hiroshima and Nagasaki combined. Needless to say, that would devastate a good portion of the Earth, but it's nowhere near as destructive as a black hole that's as wide as a nickel.
A black hole as wide as a nickel would be slightly more massive than the Earth, and would devour the entire thing, leaving nothing but a flat disk of hot rock in its wake. The black hole would then take the Earth's place orbiting around the sun, but not before sending several asteroids into the solar system to crash into various planets for the next few million years.
But you and the rest of humanity will be long dead by then, so what happens after that really doesn't concern us, right? Watch the video above to get a better sense of black-hole science and why we should thank our lucky stars that the likelihood of such an event happening on or near Earth is astronomically small.
Seriously, this is a fun, interesting animation, assuming that Black Holes are real.
Has Don Lemon been notified?
Look what the Black Hole in the White House has done to the country and the planet.
In the video, the narrator talks about a black hole with the mass of a nickel or the mass of the earth and the diameter of a nickel; all nonsense. A black hole would more likely have the mass of ten million suns and the diameter of an atom. The more they talk, the more scientists reveal they don't know what they're talking about.
Good Point. Thank God, that one lacks gravitas. . .
Here's another YouTube on the same subject, but a little less on the light side.
Nah, not for a long time. . . the Earth, probably, but the Sun wouldn't notice. The Earth would last quite some time and then the micro-black hole would orbit the sun, sweeping up debris for some time before it grew large enough to endanger the Sun.
Most people have difficulty with the idea of infinite mass in an infinitely small space. It is sometimes easier to give figures people can relate to easier to help them understand the concept.
A black hole is a mathematically defined region of spacetime exhibiting such a strong gravitational pull that no particle or electromagnetic radiation can escape from it.
Kinda reminds me of Detroit, Ferguson, Baltimore, etc
A teaspoon of black hole antimatter or matter would weigh more than a supertanker full of crude oî
600,000. long tonnes
120 times the size of my biggest freighter
I was just thinking of how one would put a black hole in one’s procket. There’s no surface to grasp to apply force upon, thus maneuvering it would be very problematic. . . You think stopping that super-tanker would be difficult, try stopping that black hole once you’ve got it moving!
Actually...no.
Instead, the sun would orbit the black hole at an amazing speed. From the perspective of the sun it would appear to take a long time for it to fall in but from our current perception of time, it would happen quickly.
The error of science is to grossly underestimate the mass of black holes; this explains such theories as dark matter and dark energy. Most matter in the galaxy is the black hole.
"Micro" black hole? Don't think so.
When we have caitlyn jenna honored as a courages national hero, ISIS murdering humans at an alarming rate, Absolute idiots running this country into the grave, the earth needs a good cleansing
Spaghettification!
Bttt
These are different scientists than the ones running CERN? Right? The ones running CERN have a complete upstanding of black holes and know there is zero risk of creating one and destroying anything or everything right?
That statue at CERN of the Hindu god of death Shiva dancing on the back of man - all a little scientist joke - right?
How can a black hole have a diameter of a nickle? I thought they were all infinitely small and infinitely dense? (With varying amounts of mass, of course.)
Thanks Swordmaker.
That was a good video. Ducks help explain everything.
I’d like them to do a video on white holes next. Also with ducks.
You are overlooking the massive radiation of propagandized media coverage. The cities you mention are more like pulsars. Still lethal if you get too close.
Nah...its thorns hammer, only smaller and heavier.
