Semi retired old time computer nerd who started programming on a Commodore Pet.

Since I'm also active in the Physics forum I should add that I started as a theoretical chemist, moved into solid state photochemistry and finally worked in industry as a colloid scientist. I only became a full time computer nerd in 1997.

comment Electrical resistivity: the effect of adding electrons
You cannot add very much extra charge to the wire. An extra charges you add go to surface of the conductor so the surface charge density quickly builds to the point where field emission starts and the charge leaks off again. The effect on the resisitivity is likely to be immeasurably small.

comment Material with incredibly small young's modulus
Can you give us a bit more info about what constrains your choice. For example could you use a polymer gel? You can make these as strong or weak as you want. However their elastic limit is very small and they'll snap under relatively small deformations. You may also have problems with evaporation of the solvent.

comment Gedanken experiment: Does it collapse to a black hole or not?
Hi David. I've linked the question that I think is the most obvious duplicate of yours, though note that the question I've linked has itself been flagged as a dupicate of If a 1kg mass was accelerated close to the speed of light would it turn into a black hole?.

comment Can everything be described without anything needing to actually “bend”?
Hi Henrik. While it's always fun to try and think up new theories for why gravity works you really need to understand the current theories for your ideas to make sense. As it stands, your question is unanswerable because it's meaningless. You'd need to formulate your ideas in a more precise way for anyone to comment constructively on them. In particular you'd have to explain why your ideas are better than general relativity, which is going to be hard since GR does an awfully good job of explaining the universe.
