Only in Sci-fi perhaps. Seismology tells us that the earth gets denser in layers towards the centre. The mantle below the crust is molten rock. Below that the inner and outer core. The outer core is mre liquid than the mantle and is composed of different material. The inner core has so much pressure on it that it is in the form of a solid.
I thought dinosaurs lived at the centre of the earth?
I saw a film about it so it must be true - it was called 'Journey to the centre of the earth' so you cant have more proof than that.
It's only recently that the world has been hollow - the last hundred years or so. As we have taken oil and coal an' stuff out of the Earth it has got hollow an' allowed aliens in whov'e set up home in there an' they're burning the oil for light 'cos there's no real sun in there an' they have to come out now and again to get air to breathe and stuff to take back to their family of aliens an' that's when we see them in the sky before they go back in an' cover the holes with crop circle. And it's true.
So thats why we are running out of oil faster than projected some years ago, I thought it was just that the OPEC rules made it advantageous for oil producing countries to overstate their oil reserves.
