Watched it yesterday. YouTube did its best to make sure that I could not watch the video, but I persisted. Mostly had to let it play for an hour with the volume muted so it would load.

I got to watch it just in time before I had to leave, so I could not comment.

It's mostly stuff I've seen before, but still pretty cool.

The thing that always boggles my mind when pondering the UDF, is that we have don't know what these galaxies look like today. That's how they looked 13 billion years ago. Are they all burnt out now? Or did they morph into something that astronomers haven't even thought to conceive of yet? It would be incredible to take a snapshot of what the universe looks like "today".

Most likely a lot of the stars in each galaxy are already long dead/burnt out, or supernovae. Distances between them and us (from our perspective) would be different and the sky view would be unrecognizable. By the time their "current light" (if any is left) reaches us our sun will have been dead by about 8 billion years, the planet earth consumed by it's expansion. :(

So your saying our biological clock is ticking and we need to get out of this one-m-class-planet solar system!

Yup.

If we solved mortality tomorrow and you could "live forever" eventually the sun will swell a bit in a billion years and make this planet uninhabitable.

If we move the planet eventually the sun goes nova in another 5 billion years.

If we spread out and live on multiple worlds eventually their suns burn out too.

If we harness black holes to provide power, eventually they evaporate and the universe dies with whimper.

So we need to start figuring out how to get out of this universe so we can live long enough to find out why we're here, even if the reason is just randomness.

A billion years is still a wee bit off.

I'm realistic; just waiting for Betelgeuse to explode.

Everytime I watch these things I sit there and just think if we truly are alone...whats the point? :)

You are a fluke of the universe. You have no right to be here. And whether you can hear it or not the universe is laughing behind your back.

Then all we have left is to try our best to make each-other's meaningless short lived spin through a tiny part of reality a little more warm.

I love you personal brain care speciallist.
