"The W and Z bosons decay to fermion-antifermion pairs." http://en.wikipedia.org/wiki/W_and_Z_bosons So, your Z boson only lasts "about 3×10−25 s"....
If particles and anti-particles annihilate each other and produce massless entities, like photons, it seems obvious that matter is made of such...
O.K. AN says that the universe will eventually end up as "Neutrinos, photons, electrons and possibly the lightest supersymmetric particle, if R...
Is Vern right? See http://photontheory.com/TheEvidence.html
Which particles are stable enough to last for eternity?
Is there any actual accepted answer to the question of what will be left over indefinitely as the universe expands indefinitely? Will it just be a...
Well, you said, "Who said otherwise? We'll probably end up with an extremely dilute gas of photons and electrons---each particle will be out of...
If fundamental strings are the fundamental entity of physical reality, and the universe eventually expands into a state of only photons, then it is...
I give up. You don't understand my point, and I still don't agree with you.:bawl:
Article II, Sec. 2 of the U.S. Constitution states:"The President shall be Commander in Chief of the Army and Navy of the United States, and of the...
Ditto.:D
It does matter. If you are not asking why to probe a deeper fundamental question, than you haven't made your point. I am not denying you can ask an...
Thanks for answering my question.:bugeye:
Please eliviate my confusion here. I thought all fundamental strings were photons, and that all particles are made of photons. Else, why would the...
So, what happens when a fundamental string colides with another fundamental string?
O.K.:D
You miss the point. Your question is less fundamental. The proposition that you can always ask why relates to an ever ending series of questions...
Nothingness would have always existed. And its existence would be something.
Why can't fundamental strings interact with other fundamental strings? That seems odd. If particles are made of fundamental strings, and particles...
So, a fundamental string can't interact directly with another fundamental string?
