Is Time Travel Possible?

No, its just an arbitrary measurement. You could pick from infinite points and define time between any two of them. Doesn't matter.

If past present and future were all real, you couldn't drop the egg off the table and wind up with different states. It would simultaneously be on the table, the floor, and every possible point in between. It would't even be an egg...but a long column of egg-matter that streams from the table to the floor, existing at all points, past present and future, with equal fidelity.

Not that you could observe it...because the light in the room would also be simultaneously existing at every possible location, past present and future.

Reality would be like a camera on an infinite exposure, rather than recording a video.

No, I said they aren't real.

Something that used to be or will be reality...isn't yet. Or isn't anymore. Its not the same to say that reality is equivalent to reality that was or that will be. The only one that is actually real is...reality. The other concepts are things that don't exist or will exist (which is the same as not existing). This is not at all the same as actually existing. It exists or it doesn't. If the past and future exist...then of course they would have to be here. Now. All around us. Thats a condition of existing, no?

If they aren't here with us now, in existence, then of course that means they don't exist. Ask yourself...is the future here right now? The past? Of course not because if they were they wouldn't be the future and the past they'd be the present.

Existing is not the same as formerly existing. Or future existing. There is only now.

Which is why the egg can be in one place on another, but not in every place at the same time. It no longer exists in the past because the past doesn't exist. It doesn't exist in the future either, because the future doesn't exist. It exists now, and only now.

Because if it did, it wouldn't exist.

And this is more the way Sagan explains it. Sagan>Tyson

Sure we can. Just have to drag the present along with us as go. Which seems to be how the universe works by default.
