the intense pressure and heat would instantly kill you
It would take 120 years to go to the center of earth
the animal will go to the shelter or they go to the adoptian center.
no
The intense heat and pressure would destroy the grenade before it could detonate. If it could some how go off, there would be no effects worth noting. The grenade would not affect Earth any more than a firecracker could move a mountain.
As you go down below the surface, the force of gravity would decrease, because now part of the Earth is attracting you from above, and less from below. At the center of the Earth, gravity would be zero.
There is no real "center" of Earth, if you are talking about on the surface. Since Earth is a sphere, the only center it would have is the core, which is impossible to get to because it is completely liquid magma. The mantle will kill you if you go through the crust.
If th sun's gravity were to disappear, Earth would go off in a straight line into interstellar space.
We would go into the sun because we don't have any inertia.. We would die
Like Mars does? For the Earth to take that long would require a more distant orbit. The Earth would be a LOT colder.
All the planets would go out of their orbits and the Sun wouldn't warm the Earth, therefore erasing all life on Earth.
We cannot go to the center of the Earth because the extreme heat and pressure would be fatal to any living being. Additionally, the Earth's core is primarily composed of solid metal, making it physically impossible for us to reach it with current technology.
our sun and moon will go backwards in the sky
