Is matter just condensed energy ?

since matter and energy are basically the same thing, and when you convert matter to energy, you release a vast amount for just little bit, I would say that is the logical conclusion.

so yes [:D]

A proton has a estimated half-life of 1032 years !

Isn't amazing that the energy packed to form a proton could be so stable and for so long ?

That is a source of great comfort to me.

It could be. The problem is how to condense it without other matter but with only energy; if we find a way then you would be absolutely right.

You just knot up the strings and you get a little ball of the stuff.

Ah yes. But they don't exist, yet  [:)]

Two photons can collide and create particles.  The most well known is probably gamma+gamma -> electron+positron pair.
...And its claws are as big as cups, and for some reason it's got a tremendous fear of stamps! And Mrs Doyle was telling me it's got magnets on its tail, so if you're made out of metal it can attach itself to you! And instead of a mouth it's got four arses!

Certainly. However the question was slightly different: not if energy can create matter but if matter itself is energy condensed.

Matter is essentially a form of localised energy and matter can be converted into energy ans energy into matter though interactions of various subatomic particles however when energy is converted into matter it is always in the form of particle antiparticle pairs which can easily convert back into energy when they meet.

I was responding to your statement that "The problem is how to condense it without other matter but with only energy"  Perhaps I should have made that clearer:)

Otherwise, I'm with science_guy in post No. 2 on this one:)

That is only in some GUT theories.

Protons are the lightest baryonic particles and so will not perturbatively (?) decay into other particles. Also, proton decay would go against the conservation of baryon number.

Some GUT theories go beyond the Standard Model and these break baryon number symmetry. This would allow the proton to decay via X-bosons and supermassive Higgs bosons. There have been experiments to look for this decay but so far no evidence of it has been found.

Recent experiments suggest that if protons do indeed decay, their half-life must be at least 1035 years.
