Scale of the Universe

I love the end of it, just a big circle of random static noise. Looking at stuff like this always brings up the question of why does anything exist at all?

The counterpoint to that thought is why we should think non-existence is even possible. There doesn't seem to be any indication that nothing could exist other than our capacity to imagine it being so.

It's what's so annoying with people arguing about "something from nothing."

Even a vacuum has zero point energy. The idea that there could even be 'nothing' at any point in time is arguably a bigger leap of faith than the notion of some deity for whose sake it is being argued as a presupposition.

If something's not reachable with speed of light, it exists only in one's imagination.

If something's not emitting any information (black hole insides), it exists only in one's imagination.

Reachable with the speed of light from what inertial frame?

Also, there's been some interesting progress regarding information about the inside of the black hole possibly leaking out in the Hawking radiation.

The speed of light is the same in all inertial frames.
