What is at the very core in earth? Could it be a fragment of a neutron the size of a car?

Question

The very core, ground zero of earth? The very core of the earth would have to be extremely dense and create a very acute gravitational field but doesn't extend out that far.. What is the substance? Could it be a small fragment of a neutron star which acted like a magnet and sucked matter to it....

Another question... The closer you get to the core of the earth does the gravity increase?

I believe the very center is a solid but everything around it is molten due to the extreme pressure.

The center of the earth doesn't lie a neutron star but perhaps a tiny fragment of one. Tiny as in the size of a small car. Over the billions of years that small, tiny, yet intensely gravatational object has attracted matter to it like a comet has done but on a much larger scale.

Answer 1

Neutron star matter is atomic nuclei (neutrons) squeezed so tightly together that there are no electrons (they've all been absorbed by protons, which is why they're neutrons). Such pressure can't even exist at the core of our sun, much less inside an itty bitty thing like the Earth. The core of the Earth is mostly molten iron. The closer you get to a massive object, the stronger the gravity. But once you get more than half way down to the Earth's core, there is more graviational mass above you than below you.

Answer 2

No. The gravity decreases as you get into the center of the earth. This is because more and more mass is on the other side of you (above) and this cancels out the pull from below. At the very center, gravity pulls in all directions with equal force, so it all cancels out. If there was a cavern there, one would be weightless at the center of the earth.

However, there is a lot of pressure in surrounding layers. That makes for a molten core (along with radioactivity). There is no way that a neutron star could have gotten into the Earth. The mass of a neutron star is at least a million Earths - 3 solar masses. If there was a neutron star at the center of the Earth, all of the planets and the Sun would revolve around the Earth. There is not enough mass in the Solar System for there ever to be a neutron star in it, unless it is a visitor from elsewhere in the Galaxy.

Answer 3

At the very center of the earth, there doesn't lie a star... why would you think that?

The earth began in the same manner of the star, though its components weren't massive enough as a whole to forumlate nuclear fusion--the main difference between a star (such as our sun) and a planet (such as our Earth). At the center of our Earth lies molten rock--it's not solid, for the temperature there is far too great (high temperature created from the pressure of top earth) for any form of matter to uphold a solid structure. All the heaviest elements on Earth lie at its center, one of these, iron, produces a magnetic field from within the core itself.

Answer 4

No. At the center of Earth is mostly iron and nickel. It's very dense and hot, but not nearly as dense as the material of a neutron star. I think you'd be interested in finding out about how our solar system formed, which is also the story of how Earth formed.

Answer 5

I think that it's a 'molten' iron core. that makes for a magnetic field.

There isn't the compression necessary to create a neutron star fragment. That's a BIG squeeze

Answer 6

1st Answer : not really. Gravitation of any body depends on its density and weight. So the heavier it is, the more gravity it has.
2nd Answer: Perhaps, but consider its weight!

Answer 7

It depends which car you are referring to...
My goodness, a neutron is a subatomic particle!

Answer 8

Isn't it just hightly condensed malten lava?

Answer 9
