the world of physics and astronomy

ashtu sic kam bere tek mjeksia edhe ketu po hap nje teme ku mund te jene shrimet ne anglisht per ti dhene mundesi edhe atyre qe kane problem me shqipen qe te mund te marrin pjese...si dhe per te shtuar ndonje artikull qe mund ti beni thjesht copy-paste ne menyre qe ta lexoj gjithkush...nese eshte artikull i gjate ose ndajeni ne me shume postime ose shkruajeni nje pjese dhe jepni linkun per tjetren...

Question miremengjes scientic moderator

Here I bring my question. Would it be possible that a space could fill up with light at a point that no more light could fit in that space???

This is - to make my question more clear -, a space with light; you put more light and you continue adding light. Would exist a point in the time where you couldn't add more light into that space???

Waiting for answers

Light does not fit in a space. Light is made up of massless particles (photons) which move (at the speed of light ).

Space with light, hmmm. When you say a defined region in space, it could be open or closed space. If it is open then you could not "fill it up" with light, as light would just pass through. If it is closed then light would be absorbed, reflected, pass through the material defining this region in space. So as you see my friend the question does not make much sense. I hope though, that I make sense to you.
But keep wondering though, this is how people come up with new ideas.
PS: try to learn a little bit about the subject in question (light) before raising questions (makes it easier to explain).

could we say in this case that a "finite" space can be filled up with an "infinite" amount of light?

PS: if we would have to learn everything before raising questions, we would be MONKEYS still

Light can NOT fill up anything. Please learn what light is, then we can discuss about implications and speculations. I think it is basic knowledge.

With regard to the last quote, this is was what I said:

Where did I express that you must learn everything!
You kids, so much to learn and so eager to try and impress everyone.

First of all, I have to say that your last message has been truly dissappointing. Just know that my ignorance is compared to your prepotency. Thanks God we are not in the times when I would probably loose my head for saying "incongruences" or for not knowing something "basic" for others.

Please, don't bother yourself trying kids -like me- to understand Phisic affairs. For nothing in the world I wanted to waste your time. Anyway, I will continue wondering about the answers that you gave me in your first message:

According to the "basic knowledge" I remember that light is explained by two theories: In one hand, as a corpuscular phenomenon and in another hand, as an electromagnetic wave. Well, you say "light can not fill up anything" but you didn't say any conclusive reason. Also u said: "If it (space) is closed then light would be absorbed, reflected, pass through the material defining this region in space”. It makes me wonder why??? That space can’t be covered with a special “impervious” material, to reflect the light inside without any loss??? Something like optic fiber???; furthermore I don’t believe that light can’t be isolated into an empty “closed” space and to see what happens there.

Ok, maybe you would better understand if were in my position. It is pretty difficult to explain answers under "certain" conditions.
This (What light is) is something basic with respect to the discussion not with respect to me. You opened this discussion and as such it is expected that you know the basics of what we are trying to assert here. If you don't then it makes it difficult for others to explain their answers.
Here come some of the answers to what you wrote in the last message:

If you assume you have an enclosed vacum space, with material that is perfectly reflective (is possible) then the only way for the light to escape is through the same avenue that it enters. So you can not avoid this if you have an outside source. The only way to set up such conditions that you imply, will have to use an inside source. And if such then when light is produced will be absorbed again by the same material that is beeing used to released in the first place and will continue as such in a loop. So you can't "fill up" the space after all.
Does it make sense? Let me know...

Ok. I have a question. I have a hard time understanding the multidimesions or imagining the simplest example. Can anyone help with that or recomend any good books that would give me some kind of insight.
thanks

One example used to explain the space curvature is to imagine the 3-D space as 2-D flat space and imagine that we can't see above (Z-Direction) only left/right (x-y direction). And everything is flat. Then the 4th dimension would be the Z direction but we have no way of explaining (at the moment). We think there are many dimensions, we can use mathematics to describe them but physically I do not know any model that describes the 4th dimension and above (not including Time as a dimension).
Hope this makes sense.
