An international team of astronomers has discovered 25 new quasars by analyzing multiwavelength data from various surveys.

The discovery in 1998 that the Universe is expanding faster over time shook the foundations of cosmology. This finding ...

In ΛCDM, Λ refers to the cosmological constant – a parameter introduced by Albert Einstein to counter the effect of gravity ...

So is it true that only geniuses can solve this math equation? I reached out to a mathematics professor to help me run the numbers on this tricky math problem. You’ve no doubt seen this math ...

Specialization is for insects.” So, in the interest of not being insects, here are my top-five physics equations you should know. 1. Newton’s Second Law I’m sure you've seen this one before ...

This incompatibility, while not yet definitive, has stirred up major questions about the validity of Einstein’s groundbreaking equations when applied to ... periods based on the distance of galaxies ...

An increase in the wavelength of light due to an object moving away manifests as a shift toward the red end of the optical spectrum and is therefore referred to by astronomers as a "redshift." ...

which gives rise to the equation of state (EoS) parameter larger than -1 in the past and less than -1 today, satisfying current observations. We also study cosmological constraints on the model using ...

In this equation, ψ denotes the star formation rate as a function of the redshift z. Let’s break some of that down. Since the early 20th century, scientists have known that the cosmos is expanding.

To mathematicians, equations are art. Just as many are moved by a painting or piece of music, to those who appreciate and understand math, expressions of numbers, variables, operations and ...

In time, new technologies will be able to detect the tiny effects of gravitational redshift, and consequently distinguish a modification of Euler’s equation for dark matter from a modification ...
