"Theoretical physicists have proposed many possible scenarios, from gravity being inherently classical to fully quantum, but the debate remains unresolved because we've never had a clear way to test gravity's quantum nature in the lab," s ... read more Reusable debris collector promises leap ...
Surface tension is like a "skin" of water. The "skin" is there because water molecules (分子) are drawn to each other. One example on the Earth is that some bugs (昆虫) can "walk on water". Most of the time, gravity is too strong and it breaks the "skin". But with zero ...

mass, so they should not be able to stay together. Mass, and consequently additional gravity, are missing to keep them from hurtling through space. The missing element which could explain the additional gravity is dark matter which astrophysicists have been trying to detect and determine its ...
A black hole is a spot in space that has(1)___ (power) gravity. Its gravity is so strong that it pulls everything nearby into it, stars, planets and other things. Black holes form when a star dies. When that happens, a huge amount of matter crowds into a very small space, (2)...
