How do a magnet do?

Fucking miracles.

And note that a changing b field moves electrons well guess what? Moving electrons electrons generate a b field. An electromagnet is just a coil of wire with current flowing through it.

At the atomic level electrons are whizzing around an atom forming little current loops. Some atoms have more flowing one way than the other (net angular momentum) and hence are magnetic.

Whats your take (simple) on the EM drive (or similar)?

Haha! You have been bamboozled by me, retarded magnet fag.

If i traveled back in time half a year would i be left sitting in empty space because the earth would be on the other side of the sun?

That it's bullshit. Sadly. If it did work it would completely change everything we know about physics but when it's between that and experimentalist fucks up, well you usually take the latter because it is far more common.

Remember the FTL neutrinos at CERN?

Well it looks like all the electric current is moving perpendicular to the B field lines. What is bamboozling?

Wouldn't you expect to travel along the same path in spacetime but backwards?

I.e since you never left the Earth as it went around the sun you wouldn't as you go backwards? Why do you think you are special that the laws of physics are not time reversible for yourself only?

Because leaving your place in time would mean leaving the current world you are in. If you travel in time how are you maintain physical proportion?

The fact that I wasted your time by asking how a magnet works when I already know how a magnet works! Trickery at it's finest.

That would then imply that he never actually time-traveled. Of course, I know that spacetime isn't an actual thing.

What if by traveling through time you were simply combining matter in a state which previously existed?
