Nasa simulation of falling into a black hole
You might also want a nice reminder of why the black hole looks like that: *related=https://videosift.com/video/Visualisation-of-a-black-hole-accretion-disk
(hint: as with many things Black Hole it looks like that but isn't actually like that)

Tesla Turbine
This is all true and it's a very cool turbine, but it doesn't scale up due to the forces on the disks.
Here's a nice explanation of how it works and why it won't scale: *related=https://videosift.com/video/Tesla-Turbine-The-interesting-physics-behind-it
Border Collie Disc Caddy
She does a lot of what a caddy does, so not deceptive imo. Just a technicality if even that…..
….after finally looking it up, I found I’m wrong twice.
1) singular of caddies is caddie, not caddy
2) it’s simply someone who is an attendant for someone playing golf (or it’s derivatives), so carrying the clubs/disks is apparently not a requirement.
I can admit I was w-w-w-wrong
I guess my title (not the original) is just a deceptive teaser headline kind of thing. Never played golf with either balls or discs, but I can recognize a smart dog.
Border Collie Disc Caddy
Absolutely yes.
My lab carried my disks, rags, place markers, and sometimes even my cigars in her backpack until she was paralyzed. She was my caddy.
My Shepherd would only chase the disk and “mark” where it stopped by touching it with his nose, but I never taught him to sit there so you had to watch him closely. He was not a caddy.
I’ve also known people who performed the same duties for friends, boyfriends/girlfriends, even for the “blind” disk golfer I played with a few times (he actually beat me). I’ve seen people tired of playing all day caddy for their friends quite often.
I’ve also seen caddies used in tournaments.
It’s not the norm, but it’s certainly not unheard of by any means.
Edit: is a caddy a prerequisite for it to be “golf”? If so, I guess there are a bunch of municipal bumpy ball whacking fields, but no municipal golf courses?
I will say, I’ve never personally seen electric disk golf carts.
So you're saying there actually are "disc golf caddies" that carry discs? Because if not, I think that's just a different category, and doesn't necessarily involve any carrying. Except when you give the mulligan signal.
Border Collie Disc Caddy
No, it’s “disk golf”. A separate entity from “golf”.
That’s like asking “is it really tennis if you play it on a table?”. It’s table tennis.
Is it really hockey if it uses air not ice? It’s air hockey.
Is it really a bicycle if it doesn’t move? It’s a stationary bicycle.
Is it really golf if you play it with a disc?
Border Collie Disc Caddy
Hmmmmm. Impressive, but is she really a caddie if she doesn’t carry the disks?
I had a shepherd that would find my disks, and a lab that would carry them in her backpack. Good times….good times.

I would be interested to see what would happen just before the disk stopped and suddenly there was no gravity. Even though it sounds like it's spinning faster I'm sure it's just because the edge of the disk is just closer to the mirror.
Suddenly without gravity would the energy cause the disk to rotate making it look like a ball floating in space or would it wobble and take off in one direction?
Could this even be done in space?
Are there any mathematicians in the audience tonight?
Are four questions in a row too much?
Homeless Teen Meets A Deaf-Blind Man...
I played a few rounds of disk golf with a blind guy, he kicked my ass.
