Creating Mass from Energy: Understanding the Physics Behind It

[Arroiyyaan]

can mass be created from energy?

 

[SteamKing]

Not by humans, AFAIK.

can mass be created from energy?

Yes. For one example, a sufficiently high-energy gamma ray photon can under the right circumstances give up its energy to form an electron and an anti-electron. For another, high-energy collisions in particle accelerators routinely generate sprays of interesting particles of various masses.

And there's another way. A hot object has a very tiny amount of extra mass compared to an identical cold object. So you can create mass just by supplying heat energy to an object.

Is there yet another?Does a compressed spring have more mass than an identical one that is not.

It does indeed.
