MOND theory is so intersesting as well. First of all, the important point is the total garavitational acceleration, what i mean is that, we can not test MOND theor on Earth, the gravitational acceleration between Pluto and Mercury is higher than a0.Secondly, we don't see any dark matter affect...
"Questions about admission to Cornell University"
I will take my Bsc. in Physics next year. And I have already started to think about my Msc. degree. I m considering Cornell Univ. My cGPA will be like 3.40/4.00.However, my core courses averege is about 3.70/4.00. And I have strong...
"the mass of photon"
I definitely know that photons don't have any mass if it is moving with it's well-known speed. However, it has its rest mass. So my question is
The energy of photons depend on their frequencies, however the freq. may differ from photon to photon. So I think their rest...
After the supernova explosion, if the remaining (core of star) mass is 1.4 solar mass, the remnant becomes neutron star, if mass is less than this value, it becomes white dwarf. finally, if the mass of remnant is approximately 3 solar masses, the degenerate neutron pressure can not prevent to...
"Apparent magnitude" is a kind of brightness quantity. But as you guess, brightness depends on the distance between observer and a object. Apparent magnitude is just the brightness, when you observe it from the Earth with, or from space telescope from space. But be careful, its unit is not just...
"Missing Matter"
Heyy Dear friends,
I and two of my friends 'll start to make a new project based on "dark matter problem".We are trying to make a simulation on galaxies which have diffrent surface density that is one of the parameters we have to determine. There are also other parameters...
