To solve the Crisis in Cosmology, astronomers are measuring the Hubble constant with magnetars, neutron stars with strong magnetic fields.

Astrophysical Masers, Megamasers, and their important role in astronomy
Masers are an example of how naturally occurring phenomena could create coherent and amplified radiation making them useful in astronomy
Gravitomagnetism: We may not need dark matter after all
Dark matter may not exist. Instead a phenomenon predicted known as Gravitomagnetism could explain the high rotation curves of galaxies.
Population III stars blast imprints in the cosmic microwave background
Astrophysicists count the number of mysterious population III stars by observing the imprints they leave in the cosmic microwave background.
Gravitational waves turn dark matter into black holes as the universe dies
Physicists found that dark matter halos will eventually collapse into black holes as they leak energy through to gravitational waves.
Could exotic life have existed in the early universe?
The higher temperature of the universe could have allowed very exotic life forms which do not need water to existed just after the big bang.
Can Dark Energy be studied using Gravitational Waves?
Introduction Before talking about dark energy, we need to talk about gravitational waves. In his theory of General Relativity, Albert Einstein predicted the existence of gravitational waves. Since then, astronomers have recognized the usefulness it provides for humanity to understand the universe in new ways. Much like what radio astronomy did in the 1930s. With […]
Could gravitinos be the solution to the Hubble Tension?
Physicists have theorized that supersymmetric dark matter particles could be the solution to the Hubble Tension. One of these supersymmetric particles could be the hypothetical gravitino. The gravitino is the supersymmetric partner of the as of yet undiscovered graviton, the hypothesized messenger particle for gravity. The Hubble Tension and Supersymmetry A research paper recently published […]
