in your opinion how far off is the horizon in that image?Therefore the distance to the horizon is 0.81 miles.
Look at the horizon and the shadow of the "spaceship" in this pic or ANY moon landing pic for that matter....

Since the moon has no atmospherethere should be no refraction.
So there should be a clear, 360 degree horizon, 0.8 miles in distance, in every direction from where the guy is standing.
.....but that's the moon tho right?
14.7 psi...If an object is heavier than air it's falling to the ground.
If it's lighter than air it's gonna float up to the sky.
Where does gravity fit in? Oh right, it determines the weight of everything on earth right? .......like how humans weigh less on the moon because of less "gravity"?
can a helium balloon float into space?
how about a hydrogen balloon?
