It Doesn’t Matter. It’s Only Time.

I write a post each year on January 1. Sometimes these are personal, but this year, I want to talk about time.

I don’t believe in time itself. What I mean by this is that time is a reference frame and a useful tool, but it isn’t a real thing beyond that. Beginnings and ends are all relative.

As far as ends go, there are countless ways for human beings to go extinct. We could blow ourselves up with nuclear bombs. Climate change could lead to the planet being uninhabitable for humans. A near-Earth supernova could cause a mass extinction event and end human life.

Suppose, even, that this planet is in the Andromeda Galaxy, the closest to the Milky Way, approximately 2.5 million light years away.

This means that the light that these intelligent creatures are viewing is old. Very old.

They are seeing light from an earth that is nothing but distant history to us – the first appearance of the genus Homo.

They are seeing history.

They are seeing Earth’s past.

They won’t see today’s light for another 2.5 million years.

Kind of makes you feel insignificant, doesn’t it?
