Post The Science-and-Skepticism-i-est Images You've Got

"Extremely"?

This picture is fake. It it were real I would see stars in the background.

If it were real there would be a heck of a lot more space between the planets.

I believe David Hume is one of the ugliest people I've ever seen.

Why? Seems like a rather ordinary Scottish man of the low nobility in 18th century Scotland.

If it were real there would be a heck of a lot more space between the planets.

That and the Earth would be in the center like God intended.

Also looks flat from here.

Since Jupiter's red spot is 3 times the size of earth it does seem off but we have to account for the distance between earth and moon.

Exactly my point. The relative sizes in that movie are totally wrong when viewed from the perspective of the surface of Earth. 

If Jupiter were as close as our moon, it would fill the entire sky.

And float.

And we'd all be fried from the radiation.

If Jupiter were as close as our moon, it would fill the entire sky.

Why do you think that? How big do you think Jupiter is? How big do you think another Earth would look if it was as far away as the Moon?

[gmalivuk]

Jupiter is 43441 miles in radius (sorry, Google thinks I want miles because I'm in the US).
The Moon is 238900 miles away.
At that distance, that length covers about 10.5 degrees. So Jupiter would look to be about 21 degrees across.
The Moon is about half a degree across when viewed from Earth.
The Jupiter in the video looks to be about 45 times bigger in diameter than the Moon.

What part of the above is wrong? Or what important thing did I miss?

Edit: Even at perigee and accounting for Earth's radius, Jupiter would appear 23 degrees across at maximum. Which means that the full disc would fill 2% of the sky, in terms of the solid angle.

[gebobs]

Looks about right to me.

a=arctan(diameter/distance)

d(Jupiter)=140000km
D(Earth-Moon)=384000km

a=arctan(140/384)=20.0°

[gebobs]

They missed a couple.

Yeah Saturn woulda been cool.

[gebobs]

How big do you think another Earth would look if it was as far away as the Moon?

~2°

[Morvis13]

BTW, not a very good movie.

[gmalivuk]

It's hard with a "photograph" like that because photos can be very zoomed-in.

A US quarter held 27 inches from your eye would cover the Earth at the average distance of the moon.

A standard NBA basketball, with its center 2 feet from your eye, would cover Jupiter.

Relative to the usual things we see in the sky, sure that's big enough that you could figuratively say it fills the sky. It sure as hell would dominate everything else up there.

Today Valve announced the third game in the Half Life series. When I went for a nostalgic dive into the lore... I've found that this is the title of Gordon Freeman's PhD Thesis at MIT. Then I decided to actually try to understand what this means... Very interesting!
