I think the continued existence of the time/thyme pun is the best evidence we have that time travel will never be invented.

P.S. Life tip:

1. Take the emblematic outfit of your given profession.

2. Affix a clock or image of a clock to that outfit.

3. You are now a Time (that profession).

Example:

1. Grab your apron.

2. Affix clock to apron.

3. You are now a TIME WAITER.
