What is the moment of inertia of electric dipole? What do you mean by a chronometer? What is time? When did it come into existence? What is redshift? What is four-dimensional space-time? How is time a dimension when it is just the movement of matter?
What is the application of the photoelectric effect? What is redshift? Define a ray of light. Explain the difference between intensity and solar constant. What is the evidence that light is energy? What the speed of the dark? What is meant by the polarization of light?
Comparing these relations with the observed one derivedfrom the redshift of EXO 0748-676, we come to the conclusion that it is incorrectto say that EXO 0748-676 cannot be a strange star. Various strange star modelscan show that EXO 0748-676 could have a mass of (1.3 ~ 1.7) M and a...

20:26 Was Hubble the one to discover the redshift of galaxies?This was an error on my part; Hubble was using earlier work of Vesto Slipher on these redshifts, and combining it with his own measurements of distances using Leavitt’s law to arrive at the law that now bears his name; ...
Redshiftis a term used when astronomical objects are moving away from us and the light coming from those objects stretches out. Light behaves like a wave, and red light has the longest wavelength. So, the light coming from objects moving away from us has a longer wavelength, stretching to ...
