No need to imagine. The Earth's rotation rate actually does make the stars look like this. That's why we have this image.

Chris, if your retinal afterimages last two hours, you should probably see an opthamologist. Most people's afterimages only last about half a second. If the Earth were rotating this far in half a second, well, I'm not good at math, but it would be pretty darn fast.

It's not my retinas that are involved, but my memory. I constantly notice the apparent rotation of the sky when I'm outside.
The only times I've seen star trails (or trails from any other object) in real time (as opposed to looking at a time lapse photogragh) was when I was following the advice of Timothy Leary. Perhaps that Rocky Mountain water is more potent than Coors lets on....

Sounds like your buzz hadn’t been killed yet Buzz Kill.
Just as zero is not equal to infinity, everything coming from nothing is illogical.
