What is faster than light? Prove it. What is the dimensional formula of impulse? What is the energy of motion called? What are the types of luminescence? Explain clearly. How the light comes from the Sun to the Earth? What is redshift?
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?
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 ...
Jason Steffens is an assistant professor of physics and astronomy at the University of Nevada, Las Vegas. What does cosmological redshift do to light? The cosmological redshift is a consequence of the expansion of space. The expansion of space stretches the wavelengths of the light that is trav...
Comparing these relations with the observed one derived from the redshift of EXO 0748-676, we come to the conclusion that it is incorrect to say that EXO 0748-676 cannot be a strange star. Various strange star models can show that EXO 0748-676 could have a mass of (1.3 - 1.7) M ...
Redshifting and blueshifting usually result from a stellar object moving away from us or toward us, respectively, much like the Doppler shift of a siren as an ambulance passes us; around a black hole, they're also a consequence of the way extreme gravity warps time. Soon, the black hole...
Gravitational redshift Theelectromagnetic radiationof an object is stretched out slightlyinside a gravitational field. Think of the sound waves that emanate from a siren on an emergency vehicle; as the vehicle moves toward an observer, sound waves are compressed, but as it moves away, they are ...

Another theory is that perhaps physics just worked differently in the early universe. Yet another theory is reviving an older idea known as tired light. This theory, which challenges the concept of cosmic expansion causing redshift, posits that photons lose energy over time due to interactions wit...
