  The Top New Videos list is always full of interesting, current videos. It is always recommended that you have a look through the Top New Videos, but also have a look at these:
  - Upcoming Unsifted Videos - active video submissions that neither are published to the front page nor archived to the submitter's personal queue
- Have you seen a really funny, surprising, scary, interesting, cute or in any other way extra good quality video?

Post it here, and share it with the large community of video-interested users. And - you are guaranteed to find more very good videos here already!
  Mind you, we only share videos you discover that someone else has made; if you "self link," by posting a video you have made, have posted or have interests in, you risk the ban hammer - read the posting guidelines before posting. The sift is NOT for promoting your own videos - it is for sharing videos others have made.

Neil deGrasse Tyson explains the Earth's ocean tides

Wow! I actually get to say NDT is wrong, and why!
Because the tide is not only affected by the moon’s varying gravity (its orbit is not a perfect circle) but also the sun, and they are not in a locked position, the bulge height (and slightly its position) varies. That’s why you have different tide levels and need a tide table to know how high (or low) any given tide will be. If he was correct, every high tide would be exactly the same height.
