Po si mer, te kuptova drejte.
Por, problemi eshte se Darke eshte nje njeri i vetem, kurse te tjeret jane qindra. A nuk do shkonte me mire qe Darke te kishte nje teme dhe te bente pyetje atje?
Nuk eshte e hijshme te mohohet leximi i qindra vetave, per nje njeri te vetem.
Po qe se keni deshire te shkruani per Darke, nuk eshte gje e keqe, por, me poshte, nuk besoj se do jete lodhje qe ate qe keni shkruar ne anglisht, ta shkruani edhe ne shqip.
Mbi te gjitha kjo eshte gje e mire edhe per ju...lexoheni nga shume njerez.

Po citoj ato që tha Fizikanti
If you put enough photons in a box, you'll exceed the Schwinger critical field, and you'll start to see electron-positron pair production in the box. So the pressure will rise and the box will eventually explode.
So that was the answer of the original question by darke.

wowwwww that's really interesting!! ... and freespirit would be right... this could be related with what we have learnt about the "begining" from the point of view of Religion? the first Big bang could have happenned like this, couldn't it?

This has nothing to do with Big Bang theory. It is a whole different story how big bang might have occured or if it ever did. Most physicists believe that this has happened but it has not been proven yet. There are also other theories out there that explain how we got here, some of them plausible.
With respect to religion, it would be very ill advised to involve religion in the BIG BANG theory, as this scientific part of the forum would become philosophical at best.
Keep wondering...

I was re-reading all this above, and another question has come to my mind. It's about the light again... since the light contents energy... can the light exert a force on the matter? when the light hits against an opaque object and it's absorbed, that energy must go to some place, where does it go?

Light or photons exert a very small force on matter when they collide with it. Making use of this fact (conservation of momentum) many ideas have come to forefront on how to use it to build the next generation spaceship. The benefits are obvious:
1. No need to use propellant for acceleration.
2. Can reach very high speeds (predicted 1/10 the speed of light).
3. Clean.
4. Low risk level (with regard to propellant).

There are also disadvantages to this solution as you would need a source (the sun) which would have to be close enough (within solar system). A very large mirror would be required to obtain the necessary acceleration to make a mission feasible. Take a look at these websites for more info:

why a mosquito doesn't sink in the water and can walk in its surface?
