Ask Science@lemmy.world•What is the limiting constraint on space based kinetic weapons in the present and future?English
3·2 days agoRods from God deliver the energy of about 12 tons of TNT.
For comparison:
The British used 12 ton “Tallboy” bombs, carried by Lancaster bombers, in WWII against submarine pens.
The “Little Boy” nuke delivered the energy of 15,000 tons of TNT.
Some modern ICBMs carry 10 warheads, each of which delivers the energy of 475,000 tons of TNT.
One benefit of dropping a tungsten telephone pole from orbit is that there’s no good way to stop it, because its just a chunk of metal moving very fast. Hitting it with a missile might scratch the paint, but won’t significantly alter its course.
The main drawback is the expense of getting them into orbit. Falcon 9 can lift 2 of them if the poles are cut in half to fit under the fairing, at a cost of about $70 million. That does not include rocket engines, fuel, and targeting computers needed to get those 2 tungsten rods out of space and onto target.

27·24 days agoIDK, I think we’ve seen adequate evidence that a lot of people out there are unswayed by facts and logic, and many of the ones who can be reasoned with are vulnerable to sophistry, sealioning, and other bad faith propaganda/debate techniques.
Even an informed public seems incapable of making good decisions.

RFK’s idea about how to make America healthy seems to be to kill everyone who isn’t already immune to the viruses that vaccines protect against.
If the only people who survive & breed are the ones who don’t need expensive medical care, then over time the population’s profit margin increases.

Also, we’re kind of already there, the main difference seems to be that we’re not sacrificing nobles en-mass (yet).
The wiki article makes it sound like a custom born of perceived resource scarcity where they would send some people away so the rest could have more.

Explain Like I'm Five@lemmy.world•Why is China selling US treasury bonds worrying?English
11·2 months agoUSA has been allowed to roleplay as world police using other people’s borrowed money to supplement oil revenue to pay for their army.
China’s push toward electrification & USA’s recent self-goals undermine the world order that USA has been perched on top of since WWII.
If the rest of the world collectively decides they’ve had enough of USA’s bullshit, they can just choose to stop lending money for nonsense like a dozen aircraft carriers full of F-35’s.
Among the consequences of living in such a world, is the various regional hegemonies would need to arm themselves to police their own backyards. Pakistan and India. Saudi Arabia, UAE and Iran. Russia and EU. If they all got a cut of the global military production that today arms USA, would they use it against each other?
