I divide atoms into two different family, one is gas family other is solid
family. The difference is based upon there magnetic property. Yes two
solid and gas atom has opposite magnetic property like couples .
For eg imagine: gas atom is female atom and solid atom is male atom.

Sun core is made up of prefect gas atom and like wise
Earth solid core is made of prefect solid atom.

Let us imagine hydrogen atom is prefect gas atom.
Can you change this perfect gas atom into prefect solid atom???
Then which is prefect solid atom, atom present at solid core.
Can you change hydrogen atom into perfect solid atom??

That is can you add or mix hydrogen atom with our solid core of earth?
If you add then you can see the effect of anti gravity of hydrogen.

But when we add or mix hydrogen atom with core of sun, then you can see
the effect of gravity of hydrogen
