anti-matter is formed because anti-quark is formed ...
i went down to cern last week and asked them how do they make anti-protons, the guy explained that its made by colliding two protons... tho he did explain, but i didnt understand him fully, he said something abt anti-quarks... can some...
I got this from a book anyway
An astronomer called William Herchel used some very accurate and sensitive mercury thermometer, he placed one in front of a spectrum of light and found that as he moved it across the bands of different colors from violet to red,the temperature rose.
this...
its my exam question.. i am not so sure... but i put it can't because sound is a wave of vibration which it can diffract but not interence... but i don't know.. can sound wave interference?
cheers
I don't much about it.. but according to Einstein's equation that E=MC squared which suggests that the mass is also a factor, therefore in theory that photon suppose not to have any energy but however... photon travels through the space without stoping..just like infinity.. does photon ever...
yes but nothing is definite... some how or some day we can
think about it... spacecraft is impossible back hundreds years ago.. people won't even think about it ..
long time ago.. people would think that travel faster than sound is impossible
but they all came possible
so don't...
