How do we really know for sure? We look in space for other planets but do we know for sure??

I'm glad someone else finally realized this.
There IS indeed a smaller planet inside the earth. This planet is comprised mostly of oil and we are sapping all of its natural resources. Eventually the people down there are going to rebel and it's going to spell armageddon for the earth.
Be prepared for this coming earthly civil war. Start preparing an emergency preparedness kit. And stock up on oil now.

As you can see from the introduction here http://en.wikipedia.org/wiki/Structure_of_the_Earth the inner configuration of the earth has *not* been determined with certainty. All of the "core" "mantle" answers - which seem *so* assertive - have *by no means* been proven. Quite a number of assumptions have gone into producing such a model, which may be accurate, but most likely is *far short* of describing the actual state of the interior of our planet. In other words, this model is our best guess - but it *is* only a guess.
If you're thinking of a Pellucidarian-type moon at the core, this is extremely unlikely. Not because the theory currently in favor is accurate, but because of the way that gravity works. Essentially, the "inner crust" would have to be strong enough to support the entire earth's mass - or at least the portion that is not part of any supposed internal world.
So, the answer is that it is possible, but *highly* improbable, that either a planet or a hollow core exist. Gravity (generally!) causes large masses to form solid spheroids, not hollow balls.
However, you should definitely read Edgar Rice Burrough's "Pellucidar" series, a few of which are free online.

The density of the earth as a total is less than that of the crust, so the density of mantle and core must be greater than the crust. Therefore, the earth can't be hollow.

Yes, we know for sure. Radar, seismographs, gravimetric studies, geological analysis - all prove that Earth has a solid iron/nickel inner core, surrounded by a molten iron outer core, surrounded by a molten rock mantle, surrounded by a cool rocky crust.

interesting thought, Einstein's thought of Relativity skill that gigantic gadgets alongside with planets and stars "bend" area like a ball on a blanket; producing a "dip" in what's asserted as Quantum fabrics. The distortion of Quantum fabrics is asserted to be the reason of the phenomenon we call gravity.

Yes dear, we really know for sure our planet has a solid iron core.

Earth is solid. Measurement of earthquake vibrations proves that. And measurements of the density based on gravity does too.
