Weaponizing Black Holes

[@isaacarthurSFIA]

Author's Note There's an error at 10:40 - I flipped things around on black hole hawking radiation, energy/frequency is INVERSE to mass, wavelength is linear :) The previous discussion is right, just botched it there, sorry about that.

[@PrivateSlacker]

We'll forgive you.

[@jonathanentwisle6282]

If we're being nitpicky strictly speaking they still be technically x-rays I believe. The usual definition of gamma ray is originating in the nucleus. Hence we can x-rays of much higher energy than we are used to (see medical linear accelerators which operate at MeV energies) and gamma rays with energies much lower than we're used to (the thorium 229 clock transition is 10s of eV, which is a few nanometers in wavelength)

[@williammook8041]

Minimum mass black holes are 22 milligrams. Abou the weight of a mosquito. Arrays of them can dance around and do all sorts of things. Think of Cooper pairs of electrons and how they make superconductivity possible. So, you have two kugleblitz' interact in a way that extends their life, indefinitely. then you tickle them to get them to decay to produce a burst of energy. Now, a collection of these guys can store and process information. So, you could drop your troops in a sheet of engineered minimum mass black holes and every atom and its quantum state is stored in the sheet. You roll it up fire it at the planet, and tell the mechanism to eject your troops in the center of the Presidential Palace as its passing through. You can do other stuff with it too.

Hypothetical question based on my understand that two event horizons that overlap (touch) can't ever separate again: Imagine a 1 billion solar mass black hole (so the event horizon is massive and very gravitationally weak) is travelling at a velocity of 0.9c through empty flat intergalactic space, now imagine an identical 1 billion solar mass black hole travelling at 0.9c but in exactly the opposite direction so the two are heading roughly towards each other. The black holes paths, once all the space time warping is taken into account, aren't on a direct collision but the outer most edges of the event horizons will just 'clip' each other, ordinarily only overlap for a fraction of a nano second as these two bodies are travelling at such incredibly fast velocities and in opposite directions to each other. So firstly, am i right in thinking that if two event horizons overlap they can never 'unlap'. Secondly, what would happen to this incredible amount of momentum of each other the black holes? Would it just get instantly turned into gravitational energy? Bearing in mind when black holes normally merge it happens very slowly as black holes slowly move closer and closer together over millions of years giving of gravitational energy as that happens, so not in a fraction of a nano second as in this case. and thirdly, what would this look like? Would the event horizons remain fairly spherical and the radiated energy just insane or would they stretch and warp into a kind of long thin elastic event horizon as they shoot past each other and then over time slow down and snap back to each other?

Before watching the video, I just wanted to mention that I recently read some books where singularities were used as weapons by very advanced alien races. One was the most recent The Expanse series book _Tiamat's Wrath_ , where there was a sort of booby trap set up where once it was "tripped" extra matter was dropped into a rapidly spinning neutron star which then collapsed into a black hole and blasted intense radiation out of its poles. The other books were written by Greg Bear and while the weapons weren't exactly black holes, they were still of the "uber-massive" category (neutron stars). The books were _The Forge of God_ and _Anvil of Stars_ . Both very good books. In fact, Forge is arguably one of the best "world destruction" stories that I've ever read. The descriptions of the Earth as it literally blows up (a process which takes a long time before it reaches its spectacular fiery conclusion) and the characters you've come to know and love throughout the book dying as a result, are awesome. I highly recommend that book to anyone interested in movies like _independance Day_ and _War of the Worlds_ . It's sequel is pretty good and includes many more examples of using gravity wells as weapons, usually by dropping them into a planet's core along with another sort of catalyst mass which revolve around each other until combining with catastrophic results. Now...on to the video! ;)

The comments about "gamma ray mirrors", starting at about 22:57, overlook an important physical process, namely pair production. At energies above twice the mass of an electron - twice 511,000 eV, or 1.022 Mev - photons can produce pairs of electrons and positrons. A spherical mirror, full of gamma rays bouncing around, would soon be filled with electrons and positrons. If the mirror is made of matter, any positrons that would hit the walls of the mirror would then annihilate themselves and part of the mirror. If the mirror is made of antimatter, any electrons would do the same thing. If the mirror is made of some sort of electromagnetic field, then there would be all sorts of odd scattering processes involving gamma rays and positrons and electrons bouncing off each other, plus little explosions where the positrons and electrons annihilate each other and create photons of various frequencies. The gamma rays would tend to be turned into X-rays, and then UV, and then visible light as things scatter off each other. Add in a black hole that might absorb some of this stuff, and might build up some random rotation (angular momentum) and electric charge as things progress, and things get very messy indeed. en.wikipedia.org/wiki/Pair_production

I now have a powerful urge to snipe enemies with a bazooka.

[@nil981]

You do realize that Anti-Tank guided missiles (ATGM's) are a thing? With those you could snipe people from 5km away.

[@juanfernandez1696]

@@nil981 yes but Arthur mentioned bazookas so that's what I'm going with.

Patrick Milewski - But if you really want to kill him, use an AGM-114 Hellfire with a range of over 10 km...

Carry a missile silo armed with megaton warheads

[@ApophaticCartesian8]

Enjoyed the video greatly. You need to get all these episodes on DVD so I can buy them from you Isaac.

[@aitchpea6011]

Well, ain't that a coincidence. I'm a few chapters into David Brin's Earth as of last night! Really interesting story, can't wait to see what happens. In fact, what am I even doing here? I should be reading right now.

[@watcherquek263]

Brilliant story... and even gravity lasers...

This is the only channel I know where black holes can be sometimes be regarded as the "safer option".

[@malcolmkhummel3]

Happy Arthursday everyone!

[@thschnick]

Am I going to end up on a watch list for clicking this video?

[@WikiSnapper]

I want a list of all of your first rules of warfare. I think that would make for an interesting video in its own right.

[@suzumiyaharuhi3438]

Hi Issac, do you plan on making vids about sci-fi weapons? For instance, what would be the difference between the effectiveness of nuclear werhead and anti-matter warhead(like photon torpedos in Star Trek) in vaccum space?

[@xxheathenxx6402]

Really love these videos. keep em coming brotha!

[@elcanucktico]

This is one of SFIA's funniest episodes! Thank you.

[@fermibubbles9375]

"a black hole is essentially a flare" - yup, there is a step down descent chain from blazars - magnetars - quasars - XPINS/RRAPS - pulsars - solar flares

[@dracoexastra]

"I'm writing this episode way back in April.. " Isaac is a time traveler confirmed

[@JabroneyDirt]

Mr Arthur - Gives a 30 minute comprehensive presentation on the the physics of weaponizing Black Holes Me - ""Wait, what's the first rule of warfare?"

[@juanfernandez1696]

The sin-gun from the alpha centaury game comes to mind.

[@SkitterComic]

Just got Brin's "Earth" book on Audible! this channel is great for discovering new sci fi

[@AdredenGaming]

That's some rockin music at the end there :)

[@baldwinlagamy4027]

If I had a list of all of Isaacs’s “first rule of ware fare” rules, there would be a hell of a lot of #1 rules.

[@onyens22]

*_Oh boy, oh boy. Is that the sweet, sweet sounds of Stellaris I hear?_* Truly, the best science channel

[@1988thefreeman]

I got some coffee and some gingersnaps, I'm ready.

[@karm65]

setting range for the collision with a black hole fairly simple shoot the first one and adjust the velocity of the second to determine the distance of the impact.

[@whatisupmyfellowamericans8808]

No one: Literally no one: Absolutely nobody: The purest essence of nothing: Issac Arthur: *_Wet's weaponize some bwack howes!_*

[@francois-xavierdessureault8039]

I love your commitment to the "first rule of warfare" joke

[@antaresmc4407]

"While its easy to hide your troops inside a black hole, you cant deploy them from there, except as Hawking radiation" Everyone: haha good joke Me: *start thinking on a Hawking powerd Santa Claus machine*
