Neil deGrasse Tyson has jumped the shark.

He's a really smart guy who brings science to the masses in a way that the masses can understand. In a time when there is clearly a war being waged by certain politicians against science, that's a valuable thing. I'm not sure what's not to like about him.

sometimes he will tweet about how something in a sci fi movie is unrealistic as if the whole movie is based on fact.

YOU'RE TELLING ME THAT BACK TO THE FUTURE ISN'T REAL?????

Dude has been dead to me ever since he led the charge to delist Pluto from planetary status.

- The object must be in orbit around the Sun.
- The object must be massive enough to be rounded by its own gravity. More specifically, its own gravity should pull it into a shape defined by hydrostatic equilibrium.
- It must have cleared the neighborhood around its orbit

Sorry but Pluto needs to get his life together first. We start naming Pluto as a planet and then what other large orbital ice masses we letting in? Slippery slope.

Yeah but listen to this. Seriously.

If you completely shuffle a full deck of cards, it is virtually impossible that that order of cards has EVER been in existence in the history of decks of cards. Never have you EVER had the same deck of cards and you never will. And you have never had the same deck of cards as anyone in history. And you never will. Ever.

That's 52! (factorial) and it's a pretty big number.

Start by picking your favorite spot on the equator. You're going to walk around the world along the equator, but take a very leisurely pace of one step every billion years.

The equatorial circumference of the Earth is 40,075,017 meters. Make sure to pack a deck of playing cards, so you can get in a few trillion hands of solitaire between steps. After you complete your round the world trip, remove one drop of water from the Pacific Ocean.

Now do the same thing again: walk around the world at one billion years per step, removing one drop of water from the Pacific Ocean each time you circle the globe. The Pacific Ocean contains 707.6 million cubic kilometers of water. Continue until the ocean is empty. When it is, take one sheet of paper and place it flat on the ground. Now, fill the ocean back up and start the entire process all over again, adding a sheet of paper to the stack each time you’ve emptied the ocean.

Do this until the stack of paper reaches from the Earth to the Sun.

Take a glance at the timer, you will see that the three left-most digits haven’t even changed. You still have 8.063e67 more seconds to go. 1 Astronomical Unit, the distance from the Earth to the Sun, is defined as 149,597,870.691 kilometers.

So, take the stack of papers down and do it all over again. One thousand times more. Unfortunately, that still won’t do it. There are still more than 5.385e67 seconds remaining. You’re just about a third of the way done.
