The farthest thing we know of in the universe is the Cosmic Microwave Background at 46 billion light years away.

Proportionally speaking, how does that compare to the distance between the two farthest apart & smallest possible particles that are inside of a human?

I don't expect it to work completely 1 to 1 with the real solar system, obviously, but is there a decent sort of working, physical small scale model that recreates our solar system physics that I can learn about/watch a video of anywhere?

I'm debating with a Discord friend and I'm trying to gather video evidence. The best footage I could find of Earth's rotation is a video timelapse from 1990, which they say is suspicious because it's so old and that there hasn't been tons of footage of this since. The Discord friend has also sent me footage of the Earth NOT rotating from geostationary satellite footage, which they're also acting like is evidence for their side.

Anyway, I thought it would be easier to send tons of satellite footage of the Earth rotating, but I'm struggling a bit. I see for instance that there's a super high orbit satellite, TESS (which I wanted to use footage from because it's theoretically the clearest view of the Earth's movement being the farthest away from it), but I unfortunately couldn't locate videos of Earth taken from TESS or from other high-orbit satellites of the Earth that clearly show the Earth rotating.

As for the Earth orbiting the Sun, I honestly don't know where to begin in getting video evidence that 'proves' that path. Does such a thing exist? Is the Earth's orbit around the Sun even show-able by video?

Thanks!

I can't find this. Does my Google-fu just suck? I'm specifically trying to see what it looked like when Artemis II reentered and hit the atmosphere again, but from ground level.

I can only find POV videos.

I can find of course ground level videos of Artemis II after it's reentered and already inside of Earth's atmosphere and heading towards the ocean, but finding ground level videos of the moment Artemis II hits the atmosphere is what is hard to find for me.

Can anyone help? Thank you!

When I attempt this search, it looks like the most direct way to get from WI to FL via Amtrak it is to... take a bus from WI to the Chicago Amtrak and then start your Amtrak journey to Florida, since the Chicago Amtrak has some direct connections to FL cities.

Is there no really direct Wisconsin to Florida connection via Amtrak?

For instance:

If I'm looking across a football field at a building that has an open window... and I'm trying to see what is inside the window... then me taking one step to the right will barely impact my view of what is inside that window.

Meanwhile, apparently if you go even a single state west or east, you will gain a different view of the stars. Different stars will be visible to you based on your longitudinal position.

How is that possible? I feel like which stars are visible to me in the sky, with the closest star being 4.24 light years away (31,038,479,019,003,332 feet away) should barely be affected by me moving left or right by one state. That seems like the equivalent of me like moving my head a micrometer to 'get a different view of what's inside the open window across the football field', which I don't think should work to have an impact on what I can actually see.

But yet you will have a different view of which part of the 'star sky scroll' you are able to see just based on where you are positioned longitudinally. How is that physically possible?
