    Why do I find this terrifying but on the other hand after 65 years resident on earth it has never, as yet, altered my day to day life so I should just think about things without dwelling too much on the answer ☺

    It's a perfectly sensible question Denise.

    The point is that the planets - or our moon - ARE falling. But their forward velocity means they never reach the attracting mass.

    It's well explained by Newton's cannonball. A thought experiment that imagines a cannoball fired horizontally from a very high mountain. As the muzzle velocity increases to about 7,300 metres per second it never hits the ground and goes into orbit.

    Ok I have a question that I suppose I could look up but if gravity keeps us from floating away why do the planets and so on stay put? Why don't they just fall? Not that I know which way is down 🤔

    The Russians are small-minded. We have claimed the Sun.

    Yes, and it is possible that the Gas Giants harbour life. It seems that life is widespread throughout the universe. However, making the leap to intelligent life requires a huge amount of freak conditions.

    What if it came to earth from Venus and became us!

    It will be interesting to see how our 'enlightened' space-faring community react. However, some extremophile microbial lifeforms on Earth can tolerate space, so it may have originated on Earth.
