Is Time Travel practically possible? If yes, do we really exist at present? are virtually living in the past? When we mention time travel to the past, does it refer to a travel within the earth or somewhere out there in the space?

Ok, so say you stopped every clock in the world and then restarted them after a year you'd live a year longer wouldn't you?

will make them not to attract to each other

If so, ask away! I love thought-provoking questions, whether it be related to physics, politics, philosophy, etc.

Imagine a hollow metal sphere studded with electromagnets, all with the same pole facing inward (like a ball with rods sticking in it). When the magnets were energized the fields would be constrained by the metal sphere and be forced to focus in the center. Under ideal conditions, since the fields have no mass could they be focused-like a 3-dimensional needle- to a point below the Planck Length and poke a hole into the 4th dimension? By 'focus' I mean since the like fields repel each other, they would be forced to point directly inward toward the center of the sphere. (this is a thought experiment so real engineering/materials considerations don't apply )


p.s. Yes, I know this is a crazy question

Shouldn't we be seeing the entire color spectrum like brown and pink since they are just light with different wavelengths from red, orange, yellow, green, blue, violet, purple?
