In which case, we seem back to having two things distorting spacetime. Could mass just be the momentum of massless particles going in really small circles such that you can pack them together and call them matter?
- gpderetta 8y agoSpace is distorted by the stress-energy tensor field. Mass is only a component of that.
- marcosdumay 8y agoIf you use "mass" to mean the rest mass of something. If you use it meaning the relativistic mass, it's the entire value, not a component. Yes, using it as the relativistic mass leads to confusing papers and equations, so it's better avoided. Yet, the press does that, what makes everything very confusing for lay people. I should have clarified that the OP usage of the term wasn't optimal (although common on the media he sees), but this following discussion about word definitions seems to be completely missing the point.

- starbeast 8y agoOh, cool, yep. I didn't know that's what they are. I have basically been wondering if all matter is variations of those.
- Retra 8y agoEnergy distorts spacetime. Mass only distorts spacetime because it is a form of energy. Light is also a form of energy.
