    like the ocean wouldn't have have a current and would cause major tide waves?

    Without the moon, there would be no tides at all.

    Would there really be no tides without the moon? The sun exerts more gravitational force on the earth than the moon does. Tides would follow a different cycle, but I think we would still have them without the moon.

    This is Physics 101, or Astronomy 101. The highest tide of each 28-day lunar cycle takes place on the day that the moon's gravity pulls in roughly the same direction as that of the sun. If the moon went away, our highest tide would be equal to the difference between an average high tide and the highest tide of the month. In most places, that's only a few inches.

    Tides would certainly lack because of that. And actually the moon is moving away from us, so the tides are likely getting (very slightly!) weaker. As well (cool fact) after the moon moves so far away, there will no longer be any eclipses! OMFG! (this will take quite some time though...)

    Lol i should know this one i see it every day but is'nt it the more full the moon is the higher the tide? Also a high tide on a full moon will be followed by a low or neep tide? Or something along them lines.

    The two (or three) highest tides of each month are going to come on the days of the full moon and new moon. The lowest low tides are the same days. Half moons give you the smallest tides. In most locations, these variations are going to be noticeable only to those who pay close attention to such things.

    Worldwide, there are some rather drastic departures from the norm. In the Mediterranean Sea, the narrow Straight of Gibraltar restricts the tides to only an inch or two. At the opposite extreme, the shallow, funnel-shaped Bay of Fundy in Canada magnifies the tides to the point where the high water mark can be several hundred feet (horizontally) inland from the water line at low tide.

    Thanks notdeadyet interesting sub really. Like been said the moon is moving away from the earth so where will the moon ends up in the sun? And as the moon moves away will the earth loose its balancing force that keep us at this nice distance from the sun?

    The moon is migrating toward a slightly higher orbit, but has no massive source of energy to allow it to break free and escape. It should remain in earth orbit for many millions of years to come.

    Our big problem with the sun is going to come when the sun starts to expand greatly, which all stars do as they grow older. Eventually, everything on the surface of the earth will be burned up, and no life will be possible here. This is many millions of years in the future, so it's nothing for us to worry about. If the human race survives that long, we will have had to solve many other serious problems before that time comes.

    Also if there was no moon, it would be pitch black during night. Animal internal clocks would be completely different. The world would be 1000% different. It's a moot point.

    Will the earth loose its tilt and move more upright as the moon moves away?

    A little off subject this. The sun will swell and start to warm up the other plantets and there moons. This will take a long time in its selfs but which planets due to the warming will be able to support or evolve life?

    Not sure. The earth's axis has shifted before but we don't know the reasons for it. That's why coal has been found in Antarctica.

    Mars. Possibly some of the moons of Jupiter.

    So take it us human would have to planet hop till we came to the last one, do hope we've work out how to travel at speed of light or thats the end of us.

    Would the wind and weather be affect if there was no moon? Or it that driven by the sun?.

    without the moon there wouldnt even be the Planet Earth.. because the moon is a big chunk of the earth that got ripped off while the Earth was still cooling off

    That's one theory.
