Talk:Cosmic ray

I'm pretty sure all or nearly all NASA articles are public domain, so it's fine to upload it, but please, give credit where it's due. --Larry Sanger


Cosmic rays were initially considered to come from some source other than the Sun. This was because the Sun was thought to emit little but visible light, and, of course, cosmic rays are isotropic and would arrive at Earth from all directions.

So what? Does all cosmic radiation originate from the sun? Why does it come from different directions, then?

That is not at all clear. -- malbi


If in the future, if cosmic rays were being used as Compact Disks(CD's), they will store over 10 gigabytes of information.

Apart from the grammar ("if in the future, if") this doesn't really tell me anything—how would one use cosmic rays as a storage medium? I assume the choice of CDs is arbitrary, as I don't see any immediate similarities between CDs and cosmic rays—if it is, the sentence could be rewritten to something like "If one were to use cosmic rays as a storage medium by (insert explanation here), one would be able to store approximately 10 gigabytes of information (per some unit).

This being the only content in the paragraph "Cosmic rays in tehnology" also seems to imply that use of cosmic rays as a storage medium is being seriously considered, if it isn't, perhaps it could be moved to something like "fun facts". -- 83.109.4.202

I must say, I agree with "malbi": the sentence "This was because the Sun was thought to emit little but visible light, and, of course, cosmic rays are isotropic and would arrive at Earth from all directions." is not clear.

Just today (November 3, 2004) there has been much learned about cosmic rays (see Reuters - "An international team of astronomers believe they have solved a mystery that has been perplexing scientists for 100 years -- the origin of cosmic rays.") I hope a knowledgable person in this area will incorporate information from this research soon. Thanks, Don Bailey, Colorado, USA

Why aren't these types of cosmic rays merged? lysdexia 19:40, 20 Dec 2004 (UTC)
