Unknown mysteries of our universe.

I like the way you can see panty lines on that famous film of bigfoot.

I don't doubt any of them except for maybe bigfoot/yheti and the loch ness. Ghosts are just energy, UFO/aliens...we can't be the only planet with sentient life .

Time travel - maybe when we break the speed of light

How ironic... To me it would seem the opposite. The Yeti/bigfoot and Loch Ness monster would seem the easieest to believe.
