Bitcoin may show empirical evidence that travelling back in time will never have been possible.

-me, no earlier than 2023

I'm still pondering this, but it might have solid basis.

Say I go back to 2011 and buy/mine 1m bitcoin.

I then return to 2023 & disappear.

How would you know by looking at the timechain?

Or the chain splits into an alternate timeline with different hashes.

How would you know if the timeline split?

It would be hard to tell from this perspective.

This model assumes that time travel backwards was unique to one person. In that case, mining bitcoin early would have not likely been the best use of that power.

If backward time travel had been readily available, we would have known it by now.
