message: The references in this article refer back to this article and so provide no content. Whoever claims this is a real term should provide an actual external reference or this should be deleted. Joshua Davis 19:16, 13 November 2006 (UTC)
replies: text: Searching around a bit, I see that this is a real term(mentioned for instance in http://arxiv.org/abs/hep-th/9506082 and other Arxiv papers). So I retract my suggestion for deletion. However the links are still worthless so I am removing them. It would be nice if someone can provide a definitive source for the coining of these terms. Joshua Davis 04:09, 19 November 2006 (UTC)
thread_title:  Reference or delete

message: I think this article should be merged with Mass in special relativity for the following reasons:
* The concepts tardyon or bradyon are hardly used anywhere. Actually I have never seen them before.
* The meaning is completely identical to that of a massive particle, which is the common concept used.
* The article has very little content.

message: A Tardon is a particle that moves slower than light
A Taxion is a particle that moves at the speed of light
A Tachyon is a particle that moves faster than light.
All three words have the same origin, I believe somewhere vaguely in the Victorian era. - I believe they are Greek or Latin and I (originally) came across them many years ago in a non-fiction book on 
extra-terrestrial life and stellar exploration by Isaac Asimov.

text: Hi Lucien86, the above three concepts (I think you have typos, the first two concepts should probably be Tardyon and Luxon) are already mentioned in the article. The origin of the terms (i.e. Greek or Latin, Victorian era, etc.) should appear in the relevant articles bearing these names. But you first have to check this, before you add it to these articles.

message: Even if it were not in a dictionary yet, it still makes sense, since it's basic word composition.
Compare to tachycardia/bradycardia which have been similarly composed.  —Preceding unsigned comment added by 70.54.202.152 (talk) 22:37, 16 September 2008 (UTC)
thread_title:  basic word composition 

message: Is it? In the luxon disambiguation page, a luxon is defined as "a massless particle in relativistic physics". Surely, then, "massive luxon" is an oxymoron...? -Anagogist (talk) 12:01, 16 February 2012 (UTC)
thread_title:  "The existence of massive luxons is a controversial issue" 

message: It has been proposed that Properties of Bradyons (whose proposed deletion was contested) be merged to this article. It seems to me that Properties of Bradyons can't stand on its own as an article, but some of its content is worth keeping and merging. -Anagogist (talk) 12:14, 16 February 2012 (UTC)

message: Tweaked the top phrasing to distinguish the colloquial 'massive' (large) from the physics specific sense (massful):
The physics technical term massive particle refers to a massful particle which has real non-zero rest mass (such as baryonic matter), the counter-part to massless particle. LarryLACa (talk) 23:26, 12 September 2022 (UTC)
