Actual Infinities

[Alex K]

Guys, answer me this.
If there's a planet 65million light years away, and they had a powerful telescope and could view our earth, would they see dinosaurs walking about right now?

Here's my take on that -

By asking the question: what happens right now 65 million light years away? you open a fantastic can of physical and philosophical worms. Strictly speaking, there appears to be no empirical way to demonstrate that what one would usually call the present, as well as the near past, have already occurred 65 million light years away, and therefore, we do not know. (This is connected to this crazy clock synchronization convention advanced creationists love, in which light speed towards us is infinite, and away from us 2*c. It is an unfalsifiable convention.)
Of course, the most parsimonious and occamy version is that indeed, we are not in a special place, and therefore we simply assume that everything in our time slice has already happened everywhere else, but if you examine this statement closely, it is questionable whether it actually means anything at all if according to current physics, there is no conceivable way to distinguish it from the situation where these remote things have not yet happened. You have to ask yourself - what does this statement actually mean - that something has already happened - for things that cannot in principle affect us, it is not clear at all if you ask me.

And if they recorded what they saw and played it back on massive Samsung lcd tv and we built a huge telescope to see them clearly as they have, would we also see the dinosaurs walking around our own earth on their tv?

Yes, that is philosophically unproblematic because it all happens in our past light cone - but I would rather ask our friends 32.5 million light years away for that favor, you'll get a bigger picture that way
