IMO, the claim the earth consists of a hard crust, then a layer molten material with solid ball in the middle, was invented by scientists for the purpose of explaining gravity.
So... volcanos
Just imaginary ya?

...If most of the inside of the Earth centre was just a mass of molten lava as claimed, the Earth would have split wide open eons ago by the massive pressures alone. Common-sense tells us that and we would be having more volcanic eruptions than we see today as the earths crust weakens over time.

I cant believe this thread is still going honestly....
And using Birds as his proof?
(sigh) Birds and planes both use wings for lift.......they get lift because gravity is pulling them down, and the drag and airflow from both sides of the wings keeps them in flight, fighting against gravity ...........
I know thats a really really simplistic view and laymans terms, but thats how it works.......
If there were no gravity or if gravity didnt pull down, they wouldnt "fly" they would float, another reason why vehicles (other than helicopters, quadrocopters etc) need to be aerodynamic in order to stay in flight.......for the same reason in space aerodynamics dont matter......
Again very very simplistic explanation...

Nothing floats in space... everything is affected by gravity in space
And there is no place in our solar system where something within that space isn't affected by gravity... Everything is pulled toward some celestial body without exception
And theres plenty of other countries that have been to space... Don't believe Nasa, that's fine... look to the other countries that have been to space
Clueless much?

Interesting...
This still involves gravity though... something that Tweedle-dee up there says is non-existent... because birds can fly
LMAO!!

Gravity pulls everything down... and everything resists it...
Why do I have to repeat myself?
Saying it's reality over and over, doesn't make it reality.
We've never gone into 'space'. Any claims that 'space' exists are from NASA, et al. Nobody else.
And if it was true, what could make gravity hold the moon, near Earth, if everything above Earth is 'floating' without any gravity?? How imaginary can this force be?? Are you serious?

When have you ever been pulled by a force, without feeling a pull? Never, right?

if gravity does not exert a force on objects [ as claimed by troll ] - why is it demonstrably easier and requires less WORK . look up the physics definition . to run down stairs - and more WORK and effort to run up stairs
