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.
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
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
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?
