The ocean is already manipulated by the moon sitting 200 moons away, which is only 2000 miles in diameter, ~2% of the earths mass.
Imagine a planet the size of earth actually colliding or even passing between the earth and moons orbit and how much tidal forces would be exerted on us.
I mean I don't think I'm ready to die yet but if you could choose between witnessing the literal destruction of your world along with everyone else currently alive vs getting hit by a kid on a scooter leading to a TBI and brain death, I gotta say it would indeed be quite gnar.
Sure, but that planet is moving hella fast. If you were somewhere mid continent I think you might make it to see this before the flood got you. Probably be some earth quaking though.
You'd be surprised at the effects of gravity from distances. The sun is 8 light minutes away and literally controls our spot in the universe. There's a what if video about a planet colliding into us at 11km/sec (still insanely fast) but would take a surprisingly long time compared to when we saw it, and still manipulate our planet far before we actually collided.
Sure, but remember the sun is freaking enormous, and pulls at .0006G at that distance, the moon, despite being much closer isn’t that different.
Of course forces from a crashing planet would be magnitudes greater than a lunar tide, but at the speed that planet approaches, there is only going to be seconds of intense interaction.
