Reply to How do the new generation of weight loss drugs (Semaglutide, tirzepatide) work and why are they seemingly so effective? by harpoonhambone
Specifically on the stomach the glp-1 receptors on the vagus nerve increase the stretch sensitivity of the stomach which then translates in lower muscle motility and acid secretion.
In the brain it seems to work both directory in indirectly through neuropeptide y and agouti related peptide. NPY is directly implicated with hunger via increase of agouti and also over expression of y is related to emotional (and physical) pain which a lot of people alleviate by over eating

Moreover by design the hydrogen fusing under certain geometries enhances the fission by a large factor.

Yes that’s why I had the “magic” crossed. Because it’s completely unfeasible. Even if we could make a one continuous strand of carbon nanotube cable that would have to be absolutely perfect in all its length. And when I say perfect I mean to the atomic level. A single misplaced atom cuts the tensile strength at less than half.
And that’s for a 35.000km single walled continuous carbon nanotube.
The longest we’ve made was 55cm.

It is but you can’t anchor one end of the cable at 250 miles because it will have to be moving compared to the ground at 28.000km/h (17.000+ mph) which means that you’d have a cable whipping around the earth at that speed. I mean the destruction would be monumental haha.
What you do is you anchor the cable at a geosynchronous orbit so it will be still compared to the earths surface at 35.000km away.
That’s a damn long cable lol.

200 miles? No. At 200 miles you need to orbit at 25mach. Try 35.000 km

That’s the whole point it won’t be billions of tons. Through magic advanced material technology it will be light.

Yes but 20 years ago it was 20 years away so the breakthrough in material science should be riiiiight around the corner.

So just that one tiny thing. Ergo not that sci-fi.
The article in a nutshell

Reply to Have you ever thought about what it sounds on jupiter by Western_Home6746
What does an explosion sounds like when it happens five feet away from you?
Well it doesn’t because the shockwave kills you way before the nerve signals have a chance to reach your brain and your brain to form the comprehension of sounds. So probably that.
