If by "in Portal" you mean the game then no. His gravity solution would result in very crippled portals that would work nothing like the game. His solution of making potential energy absolute really goes against the spirit of what makes a portal a portal.

The answer is obviously A
B cucks are low IQ schizos

He is wrong, but he is welcome to make his own game that is wrong. And he is a B-tard lol. He should have just lead with that so I wouldn't have to watch any of it.

>>16867800
his gravity simulations are can only work if gravitons exist, and there is currently no evidence for the graviton. so, no, i do not believe his portal gravity simulations are correct.

did you stop watching right before he said "i think this graviton model sucks because gravity shadows are cringe, here's my cooler model that just keeps potential energy smooth"

>trying to mishmash classical field theories of gravity with geometry while also trying to completely bypass GR
nah, fuck off with this shit.

>>16869495
he didn't to relativity at all. Its all classical gravity.

The portals themselves are a fiction. I find the assertion stupid. The portals need not conserve anything other than the cube's position relative to the portal transition resulting in speedy thing in, speedy thing out.

We don't see gravity acting like magnetic lines ever. Not even during black hole mergers where frame dragging and gravity waves exist.

>a wind sucks at the yellow hole and out the blue because of the altitude pressure differential
That would seem likely.

Pretty much, the GR considerations are the most interesting part of portal physics.
As long as the portals are close enough together that we can assume gravitational acceleration to be constant, I don't think a floor-ceiling pair would pose any issues at all. Obviously you can't use one set of coordinates for the whole space but that's never been the case.

I think that's his point. Portals are presumably a relativistic phenomenon (something which causes previously separate points in spacetime to coincide and be passed through), so you can't avoid treating the problem as a fully-relativistic one. Guy in the OP is just sloppily grafting geometry concepts onto classical field theory.

I can't stop thinking about this video. What if our universe is full of wormholes? And they distort gravity, so we can't understand why and need to assume "dark matter". What if there's even an alien-build network of such wormholes? And the closest one isn't far away from our Solar system. Would be cool.
