comment Can steel rods be welded using “cold”?
Thanks to both of you. I did not know about vacuum welding. I will have to find out more about the highest temperature limit for it. I'm still interested in the bec idea though and if it would work or not work for some reason. (Assuming you could cool the ends of the rods enough with future lasers)

Thankyou so no putting space ants in orbit around the focus point;-)

comment Time, space and matter? Apart from these what else could be in Universe?
I would have chosen spacetime, energy and gravity.

comment Black Hole - Between event horizon and singularity
I tend to think that any so call universe created would not be very energetic as I can't see how there could be any more energy/matter in it than had already fallen in. In my opinion any spacetime inside could not grow faster than light which would limit it's size.

Here's one source for you on the many solutions to Einstein's equations. news.nationalgeographic.com/news/2010/04/…

Thankyou. That will help me frame my next question.

What if the person was inside a steel box? Would there be a puff pastry point?

comment Would I get a shock from a Weyl fermion?
I'm getting a very strange picture of this. My understanding now is that you can have a current of energy, a current of charge, a current of spin, a current of holes? What gives the shock the anodization or the energy?

Then does that mean the current is nothing to do with the energy which moves a lot faster? en.m.wikipedia.org/wiki/Speed_of_electricity

How I understand "electrickery" is that electrons have a charge that flows as a current between electrons at c. Electrons move at a few meters per second or stay in the same place and jiggle. Electrons carry a current in the same sense as a human wave at a football game.
