My time machine needs to know when it is

Instead of having the device determine the time it is sent to, have it leave something in place, that you can find in the present to determine exactly when in the past it traveled. This is best if ...

Theoretically, can time be controlled locally?

In modern physics, the only thing which is capable of altering the flow of time with respect to two points in space is gravity. In general relativity, the passage of time and gravity are inherently ...

Would experiencing Groundhog Day prove that life was a simulation just for you alone?

No. It would not prove that this was a simulation for you alone, as there are other strong possibilities. This is a simulation, but not for you. Your memory of previous loops are due to a bug. Where ...

How much should a nuclear explosion be slowed for its energy to be safely converted to electrical energy?

It's not that simple. A nuclear explosion is not a simple thing. It comes in phases. Those phases are, of course, separated by very small amounts of time. One phase is the release of gamma rays. You ...

My time machine needs to know when it is

You need to know when you are sending stuff, not how much time they stayed in the past (from their perspective). So sending clocks is a no-no. One way you could do it is by collecting air samples ...

Why can't time machines go back any further than year 1900 A.D.?

Y1900 problem. Time machine software has a bug that prevents it from correctly handling years before 1900. Despite all efforts, people still think it's a hardware issue.

Why can't time machines go back any further than year 1900 A.D.?
