Did The universe really begin with a bang, a bounce? The theory that the universe is both possibly having endured a sudden ...

There are new hints that the fabric of space-time may be made of "memory cells" that record the whole history of the universe ...

This could lead to a major paradigm shift in cosmology, akin to the discovery of the accelerated expansion of the universe in the late 1990s. But on this path we may have to reckon, ...

The earliest light in the universe has been traveling across space since just after the Big Bang. Known as the cosmic ...

Step into the heart of Renaissance Italy on a journey that uncovers how curiosity, innovation, and imagination reshaped our ...

Over the past decade, cosmology has been embroiled in a growing crisis. Fuelling it are observations, first made by the Hubble Space Telescope and later by the James Webb Space Telescope, that the ...

Is the Hubble constant—a key part of how we measure the expansion of our universe—in a crisis? Some cosmologists say yes.

He told Newsweek: "In fact, the Black Hole Cosmology is just one explanation to the observation. If what we see through JWST is indeed what the early Universe looks like, it might mean that the ...

Do you have a question about cosmology? Let us know via [email protected]. Reference. Kumar, N. (2025). Creation of a flat universe-antiuniverse pair from nothing. Europhysics Letters.

For the past few years, a series of controversies have rocked the well-established field of cosmology. In a nutshell, the predictions of the standard model of the universe appear to be at odds with ...

The Hubble tension is not the only trouble for cosmology. Another one, known as the “S8 tension,” is also causing trouble , albeit not on the same scale. Here the model has a smoothness problem, by ...
