Okay so when the sun becomes a red giant, they say the earth is going to be fried(burnt up). My question, were losing the moon, every year or so we lose it by 7 inches( I believe thats how it goes), has anyone taken into account the fact that orbits grow larger(or do they?) when they say this is going to happen?

Since when have they started measuring the moon distance to conclude that we are losing it??

PLEASE ANSWER ME THIS QUESTION so I can proceed in explaining how much it all matters.

all mass exerts a gravitational force, and the tidal bulges on the Earth exert a gravitational pull on the Moon. Because the Earth rotates faster (once every 24 hours) than the Moon orbits (once every 27.3 days) the bulge tries to "speed up" the Moon, and pull it ahead in its orbit. The Moon is also pulling back on the tidal bulge of the Earth, slowing the Earth's rotation. Tidal friction, caused by the movement of the tidal bulge around the Earth, takes energy out of the Earth and puts it into the Moon's orbit, making the Moon's orbit bigger (but, a bit pardoxically, the Moon actually moves slower!).

The Earth's rotation is slowing down because of this. One hundred years from now, the day will be 2 milliseconds longer than it is now.

Pro tip: The moon used to be phenomenally close to the Earth billions of years ago - it would have taken up most of the sky at night!

100% wrong. Hilarious

it certainly used to make up a large part of the ground...the leading theories for how the moon was formed is that some sort of impact broke it off of the earth at some point

You so sure about that?

I guess 15 times as large in appearance isn't MOST of the night sky, but pretty damn.

Lol, this.

And they register the moon potentially moving CMs in a years time, roughly.
