is There Any proof Of The Hollow earth Theory

None.And it is not a theory, it is only a hypothesis ( it is a "let us suppose that..." statement).To be turned into a theory, it needs all kinds of other, weird hypotheses, such as a "metric" (rule to measure distances) that is very counter-intuitive.And of course, it would require drastic changes in the understanding of all kinds of other phenomena (for example, since the hollow Earth has no core, explaining Earth's magnetism gets very complicated).The biggest hurdle might be gravity. To explain gravity in a hollow Earth requires such a different mechanism that the Moon could not have any gravity (or, even worst, would have "negative gravity"). Or, since we know there is gravity on the Moon, then we have to conclude that the Moon is also hollow and that the whole universe is inside the Moon.But since we started with the hypothesis that Earth is hollow and the whole universe is inside Earth, then it cannot be inside the Moon.A sort of proof by contradiction against the idea of hollow Earth.

no it was disproved nearly a century ago

Absolutely none!!Sadly for this romantic concept, if today's believers are correct, the only thing that they would find there now are flying saucers.

No, and it is no theory, it is only a hypothesis. A theory is a hypothesis that is confirmed by having its predictions met by experiments - it "holds water". The Hollow earth claims are actually already wrong from the start, but that didn't stop people (eg, Newton calculated that the density of Earth below the surface must be higher than on the surface already before Edmond Halley created his hollow Earth model). A concave hollow earth (we are on the inside) theoretically working, but means actually just that you add a new level of sophistication to the existing laws of physics, a projection from our current universe to a concave one. There is no observation in physics, that is easier explained by a concave hollow Earth, if you would assume concave hollow earths as norm, many important discoveries would also maybe still waiting for being discovered, because of the additional sophistication - for example how Earthquakes can be recorded on the opposite side of Earth and what this means about the inside of Earth.It makes no sense - the same phenomena are much simpler when you have a solid Earth - eg why the sun sets and raises every day. Or why Venus has Phases.

You have several good answers, and I'll not add directly to them. Several point out that you've misused the word 'theory," where "hypothesis" is appropriate. I'd also point out that you've misused the word "proof." Theories can't be proven. Proof is in math, not science. One can proove a theorem, but theorem and theory are remarkably different words, even though they sound similar.
