i may like to explain a bit further about the Yin Yang philosophy. its basic concept is very simple: everything in the universe must exist in harmonic by having an "balancing object" which has the opposite characters. for example, man & woman, black & white, good & bad, born & death...

i think maybe quasar is the "balance object" to the BH. it's a harmonic concept of our universe, just like the Ying Yang in Taoism philosophy. tat's because quasar can emit very high energy and in the opposite the BH is absorbing i with an infinite gravitational force. btw, is the quasar also...

the answer is their time would be different due to time dilation.

that's not the problem of simultaneity. this problem can only be explained by general relativity law which we must include accereelation of speed into the consideration. if A is moving and B is standing still, it's certainly that A have to accerelate from 0m/s to a certain speed. tat's y we say...

why variable stars have various magnitudes? and y they are changing periodically?

do u mean the intensity of the wave? if yes, it's suppose to be the intensity of the flux.

just bear in mind that the speed of an electromagnetic wave must be constant. only its amplitude, frequency and wavelenght can be changed. however, the amplitude of a wave is not effected by its wavelenght or frenquency, while the wavelenght is inverse proportional to the frequency.

is that true that there is absolute energy? in my opinion, i think energy is relative as what i used to believe everything is relative except the speed of light.

TenaliRaman, in my opinion, every event in our world must has its cause(s) and it's happening by following the rules. even if i throw a dice, the forces and direction of my throwing are the causes of that event. and the result that will be shown on the dice must follow the law of physic, e.g...

sin(arcsin(x))=x true while arcsin(sin(x))=x is not true.

however, if my statement just now was true, since its size is infinity, how could we know it's expanding in a sphere shape? and not in a cubid or other geometry shape? i found there is a paradox here.

if yes? is that mean the universe is expanding from a singularity until infinity size in a sphere shape in my example?

e.g: if i say the size of the universe is infinity but its shape is a sphere. does it make sense?

until now, (unless someone can prove to me anything that cannot described with mathematics)i still believe that mathematics can represent everything. mathematics is just like the tool that the God used it to built the world. however, sometimes we cannot get the absolute value in our calculations...

does it make sense if i define that the shape of a circle is infinity, which i write its equation as: x^2+y^2 = ∞ i know that infinity means very very big until we cannot define how big is it. in this case, is the equation above still valid? can i still say that the shape of this...
