See backwards in time from the exact location I’m standing.
How did the Egyptians build the pyramids?
I’ll just visit Egypt and take a look back in time and see.
Location is problematic. The Earth rotates, moves through space and the continents move. Even if you manage to compensate for the first two, where you’d need to be in the present to see what you want to see in the past is almost certainly not going to be where you think it is.
Good point.
Let’s tie it to the object itself then rather than a physical location.
Look at any object and see it’s past as far back as you want.
Pick a brick somewhere in the middle and keep going back until the bricks past shows it getting stacked.
Would be pretty cool for things found in antique stores.
It’s not really a problem. The colloquial reference frame definitely does not move through space, and the continents don’t move fast enough to pose a problem. Just fix the reference frame to whatever’s underfoot and everything works how you would expect.

I love that the series Seven Days took this into consideration in its device.
The series is flawed in other ways, but that was neat.
