Concerning the speed of light and space travel:

When looking at the idiot box, the image is moving from the screen to my eye at the speed of light.

There is an amount of time - albeit infinitesimal - that it takes the image to get from the tube to me.

When we’re looking at, for instance that new earth-like planet, what we’re actually seeing is an image - or snapshot of time - from 20 years ago.

Whatever we see actually happened 20 years ago. Assuming the planet is 20 light years away.

So it is not incomprehensible in my mind that one day we’ll look at that planet and see the launch of a spacecraft. Directly next to the launch pad, we’ll also see a large neon sign that says, “A delegation from our planet will arrive at your door in 3, 2, 1...”

This may seem jocular in nature, and it is. But I’m seriously wondering if I have the theory correct.
