300 million light years away. Space distance is always mind-blowing. We'd still never reach that galaxy alive if humans could travel 1 million light years in a calendar year. But there's plenty of areas of the Milky Way to explore. Someday. Maybe.

Cold truth there. Happens so often it's rare not to see it, unfortunately. Appreciate the insights.

In addition to a sense of humor, it also is a display of manufactured items to any otherworlders who may happen to see them. Did he include a sticker for Made On Earth or something?

Great insights, both.

What's the theory on how all the matter and energy prior to the BBT was first compressed into the size of a house (or whatever) to begin with? The rubberband theory? Where everything goes out and returns ... still need a starting point.

Does raise some interesting scenarios about independence. How independent is a colony on Mars when their spaceships, etc. are all created on Earth?

Amazing video.

"... received a mediocre reception upon release and was nowhere near the influential masterwork that’s now considered to be one of the greatest science fiction movies of all time." Ha. I could tell five minutes into the first time seeing it that it was going to be great.

Very cool.

8 - 10 years of vigorous testing sounds more likely.

3 billion times the mass of the sun would go beyond hole and into black abyss.

Go Elon, go.

New information on roughly half a billion stars in our Milky Way. There has to be a fair number of solar systems with planets among those. The odds that Earth hosts the only life forms within our galaxy have got to be microscopically small. Toss in a billion other galaxies all with their own...

Make it profitable to mine in space and see how our capabilities grow exponentially.

All this technology and humans are just as vulnerable as the dinosaurs were.
