Time Travel Proof
400 years ago a ruler in China died and was buried. The grave was sealed. In 2008 archaeologist examined the grave and unsealed it. They were very surprised to find a Swiss ring watch in the tomb. The ring watch with approximately 100 years old. No one is sure how it got in the two. For some this is evidence of time travel. That seems like a pretty unlikely explanation, but it is a very curious thing to find in the tomb of an ancient Chinese ruler.
I question whether this is proof of time travel or just prove that someone else had broken into the tomb, it still seems like an amazing find.
