Masteria Expansions, Names and the proof for each

I'm aware of this, but this sort of thing is a lot easier to suspend disbelief on.

Also: it could be argued that the time traveling matter could still be affected directly by forces of the Earth. Basically, even though the time traveling matter would basically jump from one time to another, the matter would still be affected by Earth's gravity, which would maintain it's physical location on the Earth, even in relation to the planet rotating beneath it.

You still have to deal with the fact that Helios Tower is like thousands of feet above ground level so if you respawned in the past at the exact same physical location you'd have quite a fall.
