Q & A

Q: Why can't we see gravity?
A: First of all, we can only see the light that is reflected from things (we don't see the thing itself), and gravity doesn't reflect light. Gravitational lensing, however, is the displacement of light due to the warping of space by a gravitational lens (a massive object in space that bends light that passes by it, due to the gravitational forces). This is a way that gravity can be "seen."
