Do we have any idea what the earth's core looks like.

No, it is more than that actually. The crust is "floating" on liquid iron and rock inside the Earth, which in part creates our magnetic field. The "ball of fire" as you mentioned may be how it is described, since the Earth is broken up into the inner core, outer core, and mantle. the inner and outer core are predominantly metal, while the mantle is mostly rock, which scientists believe contributes to the moving of the Earth's plates from magma being shot out of undersea volcanoes and moving the plates around.

The earth's core is composed mainly of nickel and iron at high temperatures and under extreme pressures. The outer portions of the core are likely in a liquid state but as the pressure increases toward the center, the metals transition to more of a solid state.

Theoretically the earth's core is made up of a solid iron/nickel mass. The Mantle is broken into two parts and upper and lower mantle. They are both viscious fluids (plastic like fluids) that are under extreme pressure and intense heat. The composition of the mantle varies but is generally on the iron rich side with things like magnesium, nickel, and other accesory minerals. The crust floats on on the upper mantle like a broken egg shell. It's composed of mostly silica and aluminum. The rotation of the earth around the iron/nickel core helps generate a magnetic filed that protects us from outer space.

The center of Earth consists of molten iron and nickel. about 5500 degrees celsius. In the very center the pressure is so high that the metals are probably solid.

I think so, it might be possible. I think earth is part of the sun because a ball of fire might belongs to sun, and who knows? It's my theory, however the planets are attracted to the sun because of the gravity, and where the lava comes from, through volcano when it is active. It may explain the earth shape is round.

No, its a superheated material, molten, kind of like lava, but under a lot of pressure. Not a big empty space with a fireball in it. But nobody could describe it exactly, since nobody or thing has ever been there. But they have a pretty good idea.

Although there are many theories, I read in a book called "Why arn't black holes black?" (It's just a title, not so much about black holes, just questions and answers about science) that it's still not known what exactly is at the Earth's core.

The earth's core is composed primarily of liquid iron.

Not fire. Molten stuff, iron mainly. Much hotter than any fire you ever seen.

its a liquid center of molten nickel and other disolved minerals under high amounts of pressure
