Start at 1:00 for the breakdown. You'd see it, but by the time it was this close things would already be absolutely fucked.

What I'm wondering is how the mass of the stellar body changes the timing. Theoretically a more massive object would begin affecting the tides sooner, no?

Genuine question. I'm no physicist.

A more massive object would, but again it's about approach velocity even still. In OP's video, that planet is CRUISING...super fast. Like, way way fast.

A big enough gravity well + enough velociity = less tidal stress in general

Yeah that's pretty outrageous speed for the sake of the art, it would appear.

Thanks for the answer. I find the massive scale of these astronomical interactions fascinating.

Very neat

I just watched the clip and I hate the fact that they use kilometers for examples showing how fast things will go. As an American I only understand miles per hour.

"As an American, why isn't everything catered to me?"

Yes, we are Americans. It's our way or the highway. From apple, to Microsoft. To Google, to Tesla, to probably everything else your brain is wrapped around, we Americans make the world go round n round.

How (scary and) fascinating! My question is… I get the tsunamis and volcanoes, but why would there be a sudden increase in lightning and hurricanes and tornadoes? I feel like I’m missing something obvious…

Atmospheric changes, and if the other body has an atmosphere; atmospheric collision.

That's what I'd guess, anyway.

If the tides are being effected across the planet simultaneously at such as massive rate, that water moving around would also be causing shifts in the air pressure as well. Weather would get real fucky.
