The asteroid has no weight because no gravity is acting on it.
This external retraction force is usually gravity acting on the weight of the load.
A. Gravitational lensing is when gravity in space acts as a lens.
In space an object maintains its orbit because of the force of gravity acting upon it.
Depending on the part of the cycle, gravity might be acting to accelerate the blade, or decelerate it.
The Blade had previously discovered that gravity between stars acted in a different way than within the star's gravity well.
As a blade sweeps through each cycle, gravity is acting on the blade.
There isn't a tell-tale rush of wind as the earth turns, because gravity is acting on the atmosphere as well.
Replies: Well, gravity acts on everything since it really acts on space itself!
The problem is that even 20 billion years is not enough time for gravity acting on ordinary matter to have caused the congealing of galaxies.
