Yes i'm sure it is. I'm trying to understand if i have four dimensional space how to proceed correctly. My cat vector has to be, far as a know a basis vector, and the complex coefficients witch are...
So i have a four dimensional complex vector space ( L+ix , L+iy, L+iz, L+ig) can i choose a standard basis for it for ex: imagine that this are columns not rows ->
L+ix(1,0,0,0) + L+iy(0,1,0,0)+...
Hi recently i have try to learn for the expansion of the universe and one of the think which i don't understand is if i have two object (a and b) at fix distance between them 1000 m how this...
''r'' is gamma because the momentum is relativistic far as i know.
I'm beginner so i'm still learning. Sorry for that.
My question is if i'm moving at the speed of light what is my energy?
And also why me moving hypothetically with the speed of light is...
Hi to everyone. I want to ask something, if my rest mass is 81 kg and if i move with the speed of light, can i still use the formula for energy-momentum relation to calculate my energy?
''r'' is...

In theoretical physics, the problem of time is a conceptual conflict between general relativity and quantum mechanics in that quantum mechanics...
i meant that if i know the theory well, how i can calculate gravity, what is the method :)
Hi to everyone i'm a beginner in general relativity and i'm trying to understand which term in the theory gives the value for a surface gravity of a star?
Im little bit confused for now and this...
So what is going to be my speed as i' m going down to singularity? Is it going to be greater than the speed of light?
Is it possible a black hole to support an orbital speed behind the horizon bigger than the speed of light?
If i use this formulation it seems possible:
if M=1x10+40 kg. --> 2GM/c2 = Rs =...
Can a ball have a parabolic movement in the free space by simply throwing it?
Smaller black hole have less entropy and bigger temperature and vise versa.
Also more hottest object have more entropy and more temperature. My question is why the smaller black holes have more...
Does anybody can explain how the electron is able to emit and absorb the same (virtual) photon?
I know that but i think they are not the same beside that
Thanks for the help! In which circumstances we can say that energy density is the same as a pressure?
I'm looking for that kind of energy which can affect the space. Maybe this is a topic for another forum section.
Can you break the entanglement between two particles with just heat?
Can somebody tell me how can i calculate the total energy of a system, let's say a planet or a star?
Yes i did! I'm just wondering how i can represent this problem vie tensors i'm still in highschool. I have read about them. But i'm new and i don't understand them well.If you help that would be...
The force has direction and magnitude.
Let's put a ball in an empty space with a mass of 280 kg and a radius of 6 meters. Imagine that there is a elastic material that obey's Hooke's Law around this ball. The initial radial extent of the...
I don't understand if you are ok to explain?
Recent news !!! The linear density of the Black Hole (BH) is the maximum linear density you can have.
The formula: M/L < or = c2/2G
Some think that this is could be responsible for the...
