“For example, as an object approaches the speed of light, time slows down.”
At this point in the discussion I usually lose interest because I never get a satisfactory answer, but here are some of my questions.
If it’s all relative out there, then if time slows down as an object speeds up, does time actually stop altogether at some point or do you have to keep recalibrating time?
How does light behave (how fast does it travel) if time slows down or speeds up? Or are we talking not about “time” per se but merely about the speed of light which was supposed to be constant?
Is time (as we generally grasp it) based on some particular speed of objects (say, subatomic particles or pick your brand of basis of matter)?
Is there any...”where” external to time? Can matter exist without time or in a state where time is much faster or slower than here?
If Einstein was correct and you traveled in a circle, you could get to where you started before you even left...
