Morto

I remember been taught at school that the electricity is a movement of electrons. Ok, it's nice and clear. But then I found out that the speed with which electrons are moving in a wire is millimiters per second. It doesn't make sense to me. So what is electricity if it's not a movement of electrons and what is the speed of it?

We could do multi-tasking as a world community. Instead we do zero tasking. No matter what you think about the origins of coronovirus we did nothing to prevent it from happening again. We didn't close markets selling wild animals and we didn't put in place stricter control over virus research. It's laughable even to mention other threats like unfrozen ancient bacteria.

There are 2 main theories on where coronavirus came from. One is from wet market selling wild anymals and the another one is from the laboratory conducting dangerous experiments on deadly viruses. Both are open and operated as if nothing has happened. But let's worry about frozen bacteria on the poles.

Does it matter if the water is salty or fresh? From the standpoint of finding some life forms?

Does all water in the Solar System have the same origin? Isn't it mindblowing than Jupiter's moon Ganymede is expected to have more water than the Earth?
