The Earth as we know it
What would happen to the world as we know it if the earth were hollow below the crust, assuming it didn't collapse inwards?

Depends on how thick the crust was, and what it was made of.
There'd probably be no volcanoes.
Anything hitting it from space would probably go straight through.
Not been reading any of the "hollow Earth 'theories' " have you?

To some extent it is hollow, in that the core isn't solid.
Do you mean what would happen if the planet had always been hollow (unlikely due to the way it was formed but...) or if it suddenly became hollow?

if it suddenly became hollow, like a big balloon and then BP realised it was full of gas, they would drill deeper in the hopes of making an extra billionty billion quid next year. The main problem would be that when they hit the hollow bit, the Earth would shoot of into space in random directions, making a big farty noise, much like an untied balloon

Not quite sure how it would suddenly become hollow - which makes the question hard to answer. If it became hollow by some magical loss of mass, the impact could be quite devastating.
If it was more a case of all the core magma just poured out of a volcano, well it would kill off a lot of life in the area(s) directly. Vapourise billions of gallons of sea water, throw huge amounts of crap in to the atmosphere (Kyoto wouldn't be worth a damn) and we'd head in to full year winter (nuclear winter style) due to the sun light being severly restricted. There would then be crop failure, world wide famine and death with no doubt further death due to disease. Society would no doubt largely fall apart.
Beyond that...the coackroaches would rise up as the new supreme being on the planet

The Answer:
A hollow Earth would not have enough mass to hold on to an atmosphere by gravity, and all the surface water would boil away. If the crust had enough mass to make up for the hollow centre, there would be no magnetic field, which is generated by the Earth's liquid iron interior. Compasses wouldn't work, and some migratory animal species might get lost, but that would be the least of our worries as deadly radiation from the sun and outer space could then penetrate to the Earth's surface.
Volcanic eruptions and subduction of tectonic plates also play an important role in regulating the carbon dioxide levels in the atmosphere. Without these processes, plant growth could cease entirely because of all the carbon reaching the ocean floor through erosion, and the Earth would enter a period of deep freeze, deprived of the essential warming effect - and food supply - that carbon dioxide gives us now.
Plus coz it's so thin, just one jump would send us hurtling into space.... which sounds fun
There you go

You can perhaps see the point me asking about "how" it happened. If the mass remains, the gravitational effect of the "body" would remain the same as it is the mass not the distribution of the mass that's the issue.
