Best thread ever. Had to laugh a lot so far. Keep on going guys I just get more popcorn...

No, hot air balloons rise because there's cold air pushing them up. And you float because water is pushing you up. Wait... did you actually think that only planks of wood can push things up? Oh boy.

Water is pushing up things that float? Thats pretty dumb. Is it water pushing on each fish too? Is Gravity a constant force moving all the air with it - as we spiral through the Galaxy at 450,000 mph?

Constant velocity is undetectable between objects at that velocity. No force is needed to keep them together.

I lost my parents who were on a cruise when their ship fell off the edge of the world.

This can happen :/

Holy Medieval batman - you believe the world has an edge to fall off? Thats some archaic thinking.



It's incredible the stupid stuff you'll say, what a nutter

Yup as this chart clearly explains, gravity is a force but not a constant force - it's only there if you believe it in enough.

Yes. Water is pushing everything up, not just things that float. A rock that sinks in water still gets pushed up (just not enough to float) and will be lighter in water than in air. And air pushes things up too, which is why that same rock will be even heavier in a vacuum than in air. This magical force is called buoyancy, but it's actually gravity that's responsible for it.

You still haven't replied to the video that showed a rock falling in a vacuum chamber, by the way, despite your claims that it will float.

buoyancy is not a force in water that pushes things up - floaty objects simply dont have the density required to sink, are fish at 5000 feet deep - 5000 times stronger to resist this force?

also - which post is this video in you want me to see - but if a rock falls in a vacuum - sounds right - because the rock still has mass - things will not start floating around if you stop believing there is an invisible immeasurable but constant force pulling things to the earth and thinking they would just confirms how your concept of "No gravity" is only conceivable through the eyes of "There must be gravity - so how can there not be"? To know whether there is gravity or not - you really need to clear your mind and re-exam how things work, if your constrained by decades of your teachers telling you how to think, you will never see the misinterpretation.

So now you are about 2100 years behind.
