Hi, I wanted to ask a basic question. Can you travel in space using only electricity...? I mean, I only know rockets and Ion trusters. You need fuel for rockets and you need some kind of gas on Ion trusters that can be ionized.

Generally the problem is, that light doesn't have mass to manipulate, of course according to Einstein gravity can bend light

And then again... Can you tell me how gas can be ionized, that is converted to plasma?

And microwaves can make ions from any gas? Can it? Because I read that usually xenon is used

I wanted to ask about plasma propulsion engine. Plasma can be made by using radio waves. How this part of device looks like?(I know something, like an antenna, is used) I searched the net, but I didn't find anything. Thanks in advance. P.S Please explain as simple as you can

Which is more sensitive: eye or fingertips? P.S. touching or feeling

I don't think we can trap light because there can't be perfect angle so that light could come in and don't come out

Thanks. You helped a lot. But one more question... You said two atoms... It can be any material, could it?

Yep, the beginnig is easy, but the rest of it... not so much. For example what does it mean "lowest" energy, and does it have practical usage? I'm asking because there's almost no information in "my" language

Can someone basically explain what is zero point energy using simple english.

I heard that gravity can affect light (according to Einstein). So does it mean that all we can see is fake? We know that light comes to an eye in a straight line, but if gravity affects it, how can we be sure were seeing real things and not an illusion?

Stop electricity? Is it possible to stop electricity by stoping electrons with the magnetic field?
