It is the earth that moves. Not the stars. In video

1. Not earth, not Stars.. mind moving

[Bluetus]

2. That is really cool photography, and puts our tiny speck of the universe into perspective. But being pedantic,

the stars are all moving too. Everything in the universe is moving at an enormous rate, and other galaxies are moving away from us at something like 70 km per second per mega-parsec. That is to say, the farther away a galaxy is from us, the faster it is moving away from us. And the current consensus is that there is no force that will ever cause the universe to collapse.

3. "the stars are all moving too"

Indeed, they are. The entire universe is in constant motion.

It takes our Sun approximately 225 to 250 million years to complete an entire orbit around the Milky Way galaxy. The relative positions of the stars and constellations that we see are different than they were a few hundred years ago, and different from how they will appear a few hundred years from now...

Which is why astrology is truly ridiculous nonsense.

4. All that effort to set up the tripod and motors, and he films it with a phone.

It's a vertical strip on my screen occupying less than a third of the standard viewport.

5. Clink in the corner

Where it says YouTube snd see it full screen.

6. It's not a widescreen video -- period. It doesn't matter where or how you watch it.

It's still a vertical strip on the screen.

These Earth rotation videos are nothing new. The photographer ran the marathon, but stopped in the 25th mile.

7. Your screen name suits you.

9. Unnecessary nastiness. An obvious misinterpretation of an English language word.

8. each moves relative to the other n/t

[Bluetus]

10. Yes, everything is in motion reltive to everything else. But each object

is moving very rapidly outward from the center of the "big bang", regardless of other bodies.

As galaxies are in rotation, some of the bodies are moving outward faster than others at any moment. But in the long run, the consensus is that everything will just continue expanding outward. So if we want to visit other galaxies, we'd better do it soon.
