Does Light attract Light? Light is energy therefore E=mc^2. If it has mass it has gravity?
That's interesting. So if light doesn't have mass, it doesn't have gravity, right?
Correct. According to Einstein's theory of general relativity, mass and energy are two forms of the same thing. So an object with mass has gravity because it warps the fabric of spacetime. But since light doesn't have mass, it doesn't produce gravity in that sense.
