SunlitZelkova Posted April 11, 2021 Share Posted April 11, 2021 If an asteroid roughly 75 x 100 meters was redirected to low Earth orbit, an uncrewed ABM laser station was built on it, war broke out, the mission control center was assaulted by special forces, and the asteroid-space station was commanded to enter the atmosphere of Earth, what would the damage look like? Assuming the asteroid is solid. Quote Link to comment Share on other sites More sharing options...

Assuming the asteroid is solid. Not a whole lot. Capturing it into Earth orbit deprived it of the absolute bulk of kinetic energy, and it would furthermore be lost during the protracted reentry compared to a head-on collision. Maybe a dozen megatons, likely much less. Quote Link to comment Share on other sites More sharing options...
ARS Posted April 12, 2021 Share Posted April 12, 2021 In a lot of sci-fi movies involving brain-machine interface, there's a concept where the memories of recently dead person can be viewed by doing whatever the tech the movie has (such as the one in 'The 6th Day' and 'GI Joe Rise of The Cobra'). Now, if a person die, does the brain (which works using electrical impulses) still have memories of the deceased person even after the electrical activity has ceased entirely? Like how a harddrive that stores the data of a computer (alive) is being plugged out of the system (dead) still retains it even without power? I'm not talking about the tech to view that memory, I'm talking about whether the (recently) dead person's brain still retains it's memories and knowledge?

While I admit I do not know for a certainty, I believe the answer is in a manner of speaking...yes. I say that because DNA alone retains a lot of info after people die. However memories are not like computer memories. I do not think they could be read scifi style. We are talking flesh and blood and synapses. If you want to read that, you would need to have perfected human engineering and cloning to god-tier levels. In short...perhaps if you had a healthy cloned body you could do a brain transplant...that's assuming the brain is still fresh and has not begun to rot. Time would be of the essence, just like organ donors. Most people are not eidetic memory holders, so the clone's past stored memories would likely be associative and emotionally triggered just like for normies.

DDE Posted April 12, 2021 Share Posted April 12, 2021 4 hours ago, ARS said: the brain (which works using electrical impulses) And that's the first problem. The brain is a complex electrochemical machine that needs to stay alive to remain viable. So I don't think it would be readable past the first several hours. Definitely not with sufficient quality for a belated upload. Quote Link to comment Share on other sites More sharing options...
kerbiloid Posted April 12, 2021 Share Posted April 12, 2021 (edited) Nobody even knows how exactly the memories are stored. They can just register electric activity of the brain regions corresponding to something, "rings of memory", etc. And even partially intercept visual signals from eye nerves to show a completely bad picture of the seen, and intercept muscular impulses, reading the words before the tomgue and the throat speak them. But how is the abstract infomation is stored is not known, Also it can actually be stored in some quantum form, not directly as the electric impulses which could be an interface between the hardware and the data, then it would be like reading data from HDD with an electric tester. Afair, conjoined twins with joint parts of brain, having survived till the speakable age, could "hear" thoughts of each other. But it's from a pop article.

Starhelperdude Posted April 12, 2021 Share Posted April 12, 2021 how deep can a digged hole in the earth be without it collapsing? (like earth and stone falling from the sides into it) Quote Link to comment Share on other sites More sharing options...
kerbiloid Posted April 12, 2021 Share Posted April 12, 2021 (edited) Max delta-height of trenches and mountains ~10 km, but caves are actually at ~1.5 km. The deepest hole ~12 km, but it's partially enforced with pipes. Edited April 12, 2021 by kerbiloid Quote Link to comment Share on other sites More sharing options...

And not in a good way. But, seriously. That was pretty much the last time we'll ever see a manned test flight of an orbital spacecraft. If anything goes wrong, well, we'll name a high school after you. John Young and Robert Crippen, those guys are legends. Quote Link to comment Share on other sites More sharing options...

StrandedonEarth Posted April 14, 2021 Share Posted April 14, 2021 I have to admit that General Atomics is a great name. It just smacks of pure 50's sci-fi. It would be awesome for that name to be a major player in space, up there with NASA, ULA, SpX, BO, NG, etc... Quote Link to comment Share on other sites More sharing options...

I mean, all those engine tests, suborbital hops and drawings of rockets are basically useless when you haven't even shown your capability to get to space?
