I have a time machine at home. It only goes forward at regular speed. It's basically just a box with the words "time machine" written on it in sharpie.

They have a volume in the sense that the event horizon has a diameter. We're not sure that an actual singularity can exist, because the volume within the event horiron is unobservable, it's effectively outside our universe.

A black hole need not have infinite density. All you need is for a given mass to occupy a volume smaller than its Schwarzchild radius (at least in the case of a non-rotating uncharged black hole). In fact supermassive black holes, such as those found in the centers of galaxies can have densities lower than that of water.

This is exactly how I always pictured it. Except this is only a projection into three dimension, the actual curvature is four-dimensional.

Taxonomically speaking, all modern birds are not just descended from dinosaurs, they ARE dinosaurs.

I'm ok through trig and Calc 1 through 3, right up until differential equations... then I sort of lose it.

I prefer them with the shells already removed so I can shove whole handfuls into my mouth at once.

Yes, in fact I've eaten whole baby octopi. I didn't much care for them, and the novelty wore off quickly.
