Changes when the Earth has only an empty crust

Here is what will happen if the Earth is empty.

We have never made the journey to the Earth's core, but we are studying earthquakes and geomagnetic fields long enough to know what's inside the planet.

The core of the Earth is very thick and hot. But we don't always have to understand it. Learn how our Earth works requires a lot of time and gives rise to some strange hypotheses.

A scientist even concluded that Earth is a reverse sphere, with the entire universe hidden inside. Empty Earth is also in the ability list. But how will such a planet exist?

The answer is that it does not exist.

An empty Earth will collapse into and become a smaller sphere. Why? Because of gravity, one of the four fundamental forces of the universe. Gravity will collect every part of the crust into a block, turning the hollow Earth into an impossible hypothesis. But what's interesting in that hypothesis?

An empty Earth will collapse into and become a smaller sphere.

Let's assume, somehow, that the Earth's crust can float without collapsing into it. Oh, that's not very good for us. Most likely there will be no life on the planet. The first is because there is no atmosphere.

The Earth's atmosphere protects us from the solar wind and cosmic radiation. It needs magnetic fields and planet's gravity to stay the same. The magnetic field is produced from the Earth's core, which does not exist in an empty planet.

No core means no magnetic field, no magnetic field means the Earth will become a dead planet.

The hollow Earth will lose most of the mass, because most of the mass is concentrated inside the planet and mantle.

We are not talking about a few kilograms, as weight increases when you visit your grandparents last time, which is 5.9 trillion tons.

The hollow Earth will weigh less than 0.4% of its current mass. Gravity on an empty Earth will be so weak that it is not big enough to help you stand. You will fly into space, that is if you can survive the solar radiation.

Now, imagine that the Earth's mass and weight are not different from Earth in reality. We still have no atmosphere due to lack of geomagnetic fields, but at least we solve the gravity problem for you to stand on the planet.

The hollow Earth surface will be a very barren place. Drilling through the Earth's crust will be much more difficult because the crust needs to be formed from very dense material to compensate for mass.

When you dig through the 30km long crust and enter the planet, you will experience zero gravity. Because the gravity of the hollow Earth comes from the shell, gravity will destroy itself and no longer affect you. You will float, permanently inside the empty planet. Don't forget to wear a space suit. You will need it to provide oxygen and pressure to maintain respiration until you exhaust oxygen.

Drifting inside the Earth without wearing a space suit would be like stepping into a space vacuum. You will not want to experience it at all.
