Science is mainly based on theories, and theories are based on other theories. What our knowledge consists of is theories implemented by people who base their theories on other theories. Most scientific knowledge is far from the precise truth. For example, how can we know much about dark matter, and why do we think that there is such a thing? Why did we define what is theoretically nothing? Scientists cannot wrap their heads around something that is technically nothing, but in reality, there has to be a nonexistence at some point.


What have we actually sent through the supposed mantle? We have read seismic waves, but how do we know that there isn't just a gas inside the Earth that acts the same as the molten lava and rock we think is inside the Earth? Do we even know that there is anything inside the Earth? Maybe it's like space, where energy endlessly flows outward. What we think is a liquid could be a gas, which seismic waves may move through the same way as they would move through a solid or a liquid.
