A "hollow Earth" theory posits that the planet Earth has a hollow interior and probably a habitable inner surface. Although at one time adventure literature made this idea popular, the notion now receives little support; direct observation refutes it; substantial geodetic evidence has long since controverted it and the scientific community dismisses it as pseudoscience.

No, it is a solid / liquid ball of rock and metal. Crust (solid), mantle (semi-solid), outer core (liquid), inner core (solid). The easiest way to prove this is to listen for earthquakes. When an earthquake happens, shockwaves pass through the earth in a very predictable way, dictated by the density and type of material they pass through. These can be picked up or "listened" to using a device called seismometer. If the earth where hollow, the "patterns" these quakes produce would be completely different to what we see.
The other proof is of the earth where hollow, (say only the crust existed), the mass and hence the gravity would be a tiny fraction of what we have, about 1 hundredth of a gravity. With this gravity, there would be no air, and therefore I would not be here to write this answer!!

The earth is a solid mass. At one time the whole earth was liquid. As it cooled, the outer surface hardened and wrinkled. The center is still liquid. The liquid nearest the surface is melted rock(lava), which comes to the surface during volcanic eruptions.
When a ball of liquid material spins in space, the heavier materials come to the surface, making it seem that the earth's core might be of lighter material. To contradict that, on earth we have gravity which would draw the heavier materials to the center.
Drilling can never prove to us just what is in the center because the heat is so intense that no drill would stand up against it.

This is one of those questions a person may answer for themselves, but they need to accept the conclusion, because it is not what is taught in schools today.
Determine the acceleration values for a mass, were it dropped at different locations within our planet. Determine the acceleration value of a dropped mass at the 0.717 location from the core point of our planet, and then at the 0.716 location. At the last location, were a mass dropped there, it would accelerate beyond the speed of light in one second. In our sun the distance is 400 miles.

Stick to science please! The earth is definely NOT hollow. Lots of work going on to get a good description. Very hot crystalised iron is a close approximation.

No. There is a network of really big caverns near the surface, but the earth has a nickel-iron core and a molten 'mantle' of basalt.

Nope the Earth's layers are the crust, the mantle, the outer core and the inner core.

there's only one way to find out, you should get digging and prove everybody wrong.
It has been proven that the earth has a metalic core but don't let those heretic scientists stop you, you're onto a winner here, nobel prize material

not likely ...
simply because scientists and explorers have dug deep enough to reach the cores of the earth to prove this

Not exactly - it jas solid on top and liquid and gas in the middle.
