Shouldn't this be a redirect to rest mass? Keenan Pepper 06:26, 24 Mar 2005 (UTC)

Yes, yes it should. -lethe talk + 03:03, 16 April 2006 (UTC)
No, no it shouldn't. "Rest mass" is used to refer to a single particle or system at rest. "Invariant mass" is used to refer to a system of particles in motion, usually decay products. The rest mass of a single particle is also its invariant mass, but the two terms deserve their own discussions. Strait 18:56, 16 May 2006 (UTC)
Rest Mass currently directs to well click rest mass and see. This article discusses invariant mass and relativistic mass and describes rest mass as the same as invariant mass. I think this is the page you should be looking at. Jameskeates 13:12, 23 August 2006 (UTC)

[edit] This page is not needed?

I think that this page is not needed and should be merged with Mass in special relativity. Comments? Timb66 10:17, 28 May 2007 (UTC)

I thought so myself when I first saw it. But mass in special relativity became an experiment in popular science. I think this page should retain its conciseness, and correct message according to what is established today, for the physics student.
In fact, I would support copying everything from mass in special relativity that is relevant to today's physics to here. Thanks. Edgerck 22:59, 28 May 2007 (UTC)

I don't agree with maintaining two pages on essentially the same subject just to allow two different points of view to be expressed. Let's work to improve mass in special relativity (which i agree needs work). Timb66 09:28, 29 May 2007 (UTC)


This page is just redundant. I think that "mass in special relativity" is inclusive of relativistic mass and invariant mass. Explanation is already given in "mass in special relativity". The term invariant mass rises because of the special relativity. Thljcl (talk) 14:38, 22 April 2008 (UTC)
