Also, if the planet has a higher mass, the escape velocity is greater, and fewer particles will escape.

The particle is therefore endlessly trapped, and cannot escape from the region of the Earth.

In this way, the uncertainty principle allows particles to escape from what was thought to be the ultimate prison, a black hole.

Evidently not a particle of gas was escaping through the rock.

The particles could not escape; some of their radiant energy could.

In a pure solvent particles can escape all over the surface of the liquid (see figure 6.34).

Some lead particles will escape from the bag later and be spread around the house.

Neither light nor particles can escape through this surface from the region inside, hence the name "black hole".

There is no other side- it's a celestial body with gravity so strong that not even light particles can escape.

At higher temperatures however, these particles can escape the well and the sharp definition between liquid and gas is lost.
