John Kettler Posted February 7, 2018 Share Posted February 7, 2018 We know that e=mc2, but if I want to convert energy into mass, presuming stupendous amounts of power are available, what does that equation look like, please?

A Canadian Cat Posted February 7, 2018 Share Posted February 7, 2018 m = e / c2 As in mass equals energy divided by speed of light squared. 0 Quote Link to comment Share on other sites More sharing options...
Sgt.Squarehead Posted February 7, 2018 Share Posted February 7, 2018 Or to put it another way, the power output of a couple of moderate sized black-holes would probably be enough to create a decent sized peanut. 0 Quote Link to comment Share on other sites More sharing options...

That‘s a good one. Absolutely true, but probably not very helpful. Reminds me to my Thermodynamics professor. After explaining for hours what entropy is, somebody asked „But what exactly is entropy now?“ The somewhat frustrated answer was: „I just explained that. Entropy is „integral dQ(reversible)/T“.

All I can do is flip variables around correctly. I am absolutely no help figuring out how to actually create atoms out of energy. 0 Quote Link to comment Share on other sites More sharing options...

Currently it is probably more important to learn how to do it the other way round safely, anyway. 1 Quote Link to comment Share on other sites More sharing options...

Regards, John Kettler E=mC2 is a derivative of E2=[(m2)(c4)]+[(p2)(c2)] I think you would have to have volumes of equations and transforms based on time, angles of movement and velocities of every quantum particle involved to achieve the answer... well there is no one equation. best answer goes to Sgt Squarehead. 0 Quote Link to comment Share on other sites More sharing options...
John Kettler Posted February 24, 2018 Author Share Posted February 24, 2018 IanL, Thanks. Was hoping it was simple, not least because I wouldn't know how to type a complex equation into my manuscript! Guys, The subsequent disussion--what I could follow of it--was most edifying.
