Its water going upwards.

My shower can do that if I point it in the right direction.

It’s water going up that is supposed to go down.

When your shower starts doing that, I’d suggest you call a plumber or exorcist.

EDIT: Actually, on reflection, they might have meant the force that the water experiences due to the effects of gravity, so the tweet may not be factually incorrect, just ambiguously worded.

f***ing hell I'm bored today

What Is Gravity?
Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun.

How to Calculate Force of Gravity
Quote:
One of the four fundamental physical forces, gravity influences every engineering enterprise humans have ever undertaken, especially in the realm of economics. Being able to calculate the force of gravity and solve related problems is a basic and essential skill in introductory physical science courses.

Things do have a gravitational force though, no?

No, not really. Gravity is the result of objects warping the fabric of spacetime (note, NOT space AND time). It's more geometry than a force. There are only three forces that we are aware of (I think), the weak and strong nuclear forces and the electro-magnetic force. All from memory, may not be entirely accurate. The thing that stuck with me is that gravity is not a force in the strict definition of the word.

No, NASA isn't wrong, they know gravity is not a force, they just don't explain it to people this way because frankly it doesn't matter on a day to day basis.

That's nothing compared to a baby pissing up into the air when you're trying to change its nappy.

No links before anyone asks.

Fair enough. My understand of the tweet was that it was what armchair linked, and what the Encyclopaedia Britannia and many other scientific explanations online outline, not that gravity is a force.

It’s completely ruined the clip for me now. I’m off to shake my fist at it.

It shouldn't, it's still a great clip. To all extents and purposes here on earth we can think of gravity as a force, I was just being ultra picky

4 fundamental forces.

3 incorporated into the Standard Model: weak/strong/em

1 not incorporated in SM: Gravity

What we experience as gravity is a manifestation of the interaction of spacetime and mass.

Nice waterfall, BTW. 👍
