yes, after 8 minutes

But will we feel the shift in gravity as the planet starts moving straight?

I know gravity moves at the speed of light. I’m just referring to the slight pull of the gravity and the sudden shift to traveling straight off instead of a circle.

All of that will only happen after 8 minutes, see this comment.
Earth has a circular orbit because space-time is curved by the mass of the sun. (Think of a large bowling ball on a trampoline, you can make a small ball travel in circles around it, and if there would be no friction, it would go on indefinitely.) When the sun’s mass suddenly disappears (by pure magic, as this would violate many laws of physics), spacetime would flatten out, at the speed of light.

What part of “I know gravity travels at the speed of light” do you not understand, to make you think you’re explaining something to me?

I really doubt we would notice, because then gravity would already feel different during the day and night. Technically the sun pulls us away from the Earth in the daytime and toward Earth at night. Also toward the east at sunrise and the west at sunset. I don’t think we ever feel this.

We are in “free fall” around the Sun so that’s why we don’t feel its pull of gravity.
You would similarly feel weightless if you were in an orbit around Earth.

This is the cutting-edge of my understanding so if I’m wrong somebody call me out, but I think because gravity is warping space-time and not actually pulling anything, we wouldn’t feel an inertia change. Our inertia would be maintained, but the space-time we’re going through would suddenly be shaped different, so we’d follow a new path

The part you’re missing is that earth isn’t a point in space. That’s why there’s tides caused by the sun (which are different than tides caused by the moon)
A person wouldn’t feel the difference, but the tides would slosh back when the solar gravity stops effecting them.

So would all the other planets, so there’d be a non-zero chance we’d smack into one of them. Most likely though we’d become a very, very cold rogue planet.

How do you figure? Space is fucking huge. I don’t see how any planets could collide.
