Why did I add the single word "laboratory"? Because I could. No, actually because I saw the picture first on a very old monitor that left me confused as to what I was seeing and I misinterpreted it as a computer graphic rendition of events changing over time - hard to describe what I thought I was seeing, but as soon as I realized it was a photograph of a real physical space it snapped into making sense. That one word would have made it clear to me from the beginning. --Fitzhugh 06:37, 3 July 2006 (UTC)[reply]

Light[edit]

Is light classified as hypervelocity? It travels at a speed above 3,000 m/s but it is not matter. --GoOdCoNtEnT 17:10, 3 July 2006 (UTC)[reply]

I also saw how it says 3000m/s but then says 10000f/s, however 3000m/s is 9900f/s.

definition[edit]

Interesting article, but this article seems to define hypervelocity as over 3000 m/s and then over 2500 m/s. I'm confused by this? If no one is sure which to choose, I suggest choosing 2500 m/s since 3000 m/s is over 2500 m/s.

I think there are multiple valid definitions in the field... that's why the discrepancy. Lucifred (talk) 05:31, 12 June 2010 (UTC)[reply]

Inertial stresses where?[edit]

The article says: In particular, it refers to velocities sufficiently high that the strength of materials is very small compared to inertial stresses. I remember from Einstein's relativity ideas that no object can perform a test to discover its velocity; so therefore, what is the source of the inertial stress? - grubber 07:10, 21 January 2007 (UTC)[reply]

I think that refers to what happens on impact between two objects that are at hyperspeed compared to each other? -- Milo —Preceding unsigned comment added by 81.171.2.42 (talk) 16:18, 4 October 2007 (UTC)[reply]

Comment that "Objects Smaller than a Softball Cannot be Detected by Radar[edit]

This comment is false, and only particular radar systems cannot detect particular objects smaller than a softball. The ability of a radar to detect an object also depends on its shape and material properties, and not just the absolute size of the object. — Preceding unsigned comment added by 149.97.32.14 (talk) 18:12, 16 May 2016 (UTC)[reply]
