We've all got regrets, choices we made that we wish we could take back, that feeling

of, if I could just tell younger me to do this one thing differently.

But sci-fi stories have warned us about all the dangers of time travel.

You change one little thing in the past and centuries of history could unravel.

If you aren't careful, there might not be a future to go back to.

So maybe it's a good thing we haven't discovered the secrets of time travel.

Unless the truth is, we already have.

This is Supernatural, a Spotify original from Parkcast.

I'm your host, Ashley Flowers.

Every Wednesday I'll be taking a deep dive into a real unexplained occurrence to try and

figure out the truth.

You can find all episodes of Supernatural and all other Parkcast originals for free on

Spotify.

This week, I'm looking in to time travel, real cases of people who claimed to visit the

past and future.

I'll look at the evidence and try to figure out whether time travel is actually possible,

or at least whether we can prove it's impossible.

All that and more is coming up.

Stay with us.

Ironically, the concept of time travel has been around pretty much since humans started

keeping time.

The earliest time travel stories are from 400 BCE.
