Is dark matter baryonic? Why can't dark matter and dark energy be directly observed? Does a particle accelerator use dark matter? How much mass in the universe is dark matter? What is cosmological redshift? Is
The cosmological redshift is a consequence of the expansion of space. The expansion of space stretches the wavelengths of the light that is traveling through it. Since red light has longer wavelengths than blue light, we call the stretching a redshift. A source of light that is moving away ...
What is cosmology in philosophy? What is cosmological redshift? Does dark matter slow the expansion of the universe? Which theory of quantum gravity involves 10 dimensions? What is the equation for string theory? Which wavelength of light constitutes support for the expanding universe?

A lot of galaxies in a very small corner of the sky. Most of the color difference comes from “cosmological redshift”; the redder a galaxy is, the farther away it is. The first galaxies date to when the universe was a bit under an billion years old, with a redshift of a bit un...
Scientists are conducting studies to determine whether dark energy is consistent with the cosmological constant, a term Albert Einstein originally included in his equations to counterbalance gravity. Alternatively, dark energy may not be constant, but something that changes over the history of the univer...
Some scientists think that dark energy is a fundamental, ever-present background energy in space known as vacuum energy, which could be equal to the cosmological constant, a mathematical term in the equations of Einstein’s theory of general relativity. Originally, the constant existed to counterba...
This scenario, which may seem bizarre and may not be realizable in practice, clearly shows the essence of thermodynamic relativity. But it should not be confused with the scenario of temperature measurement in a cosmological scenario, in which the observer does not move inside the object under me...
The Webb has peered back about as far as is possible and found something that…..shouldn’t exist. According to existing cosmological theories, the universe is about ??13.787 billion years old. This is determined by the cosmic microwave background radiation and the universe’s expansion rate, ...
What we should highlight is its independence of any prior and dark energy model. With regard to this unique advantage, many analyses have demonstrated that the redshift drift is not only able to provide much stronger constraints on the dynamical cosmological models [26, 38], but also to solve...
