Are hollow planets possible?

No. A planet-sized body that was hollow would be impossible, unless it was artificial. Most rocky planets have voids, but limited and prone to collapse if they get too big. And those are in the crust: deeper down nothing is solid.

Is Earth a hollow sphere or a solid sphere?

It is a flat solid sphere, hollow in the center.

What would be the weight of the body inside the earth if it were a hollow sphere?

Zero. If the earth is regarded as a hollow sphere, then the weight of an object below the surface of earth is Zero.

What happens if Earth is hollow?

If any significant portion of the Earth were hollow, the average density would be much lower than that of surface rocks. The only way for Earth to have the force of gravity that it does is for much more dense material to make up a large part of the interior.

Is there life in the center of the Earth?

These creatures of the deep are diverse, consisting of bacteria and other single-celled organisms called archaea. There are even multicellular animals miles below the surface, including tiny worms called nematodes.

Are we inside the Earth or on top of the earth?

Originally Answered: Do we live inside or outside the Earth? We neither live inside, not outside the Earth. We live on the surface of the Earth. Inside the Earth, their is molten rock and metal.

What is difference between hollow sphere and solid sphere?

In a hollow sphere all the small particles are located far away from its centre due to which its moment of inertia increases due to this it needs 50\% more torque and in case of solid sphere it has less moment of inertia so less torque required to rotate it to the same extent as that of hollow sphere.

When a solid sphere and a hollow sphere?

Since the moment of inertia of a hollow sphere is more than the moment of inertia of a solid sphere, hence we can say that the acceleration is greater for solid sphere than the hollow sphere. So the solid sphere reaches the bottom with greater speed. Hence the correct answer is option B.

When you move from equator to pole the value of mass of a body?

When a body is taken from equator to poles, its weight increases, because acceleration due to gravity increases.

Is there gravity in space?

In fact, a small amount of gravity can be found everywhere in space. Gravity is what holds the moon in orbit around Earth. Gravity, however, does become weaker with distance. It is possible for a spacecraft to go far enough from Earth that a person inside would feel very little gravity.

What would happen if the Earth was hollow?

A hollow Earth would be less than 0.4\% of its current mass. The gravity on a hollow Earth would be so weak, it wouldn’t be enough for you to stick to the planet. You’d fly away into space. That’s, of course, if you could make it through all the solar radiation.

What would happen to the Earth if it had no core?

No core means no magnetic field, and no magnetic field means that the Earth would be pretty dead. A hollow Earth would also lose a whole lot of mass, since most of it is accumulated in the planet’s inner part – the core and the mantle.

What would happen if the Earth had no magnetic field?

The atmosphere of the Earth protects us from solar winds and space radiation. But it needs a magnetic field and the planet’s gravity to keep it in place. The magnetic field is generated in the Earth’s core, which would be absent in a hollow planet. No core means no magnetic field, and no magnetic field means that the Earth would be pretty dead.

What if you drilled through the Earth’s crust?

Drilling through the Earth’s crust would be much harder, as it would have to be formed from a very dense material to make up such a mass. When you finally managed to dig through the 30-km thick crust (18-mile), and stepped into the interior of the planet, you’d experience zero-gravity.
