That is the provocative assertion behind Professor Ginestra Bianconi’s latest work, which reframes gravity as an emergent phenomenon arising from the interplay of spacetime geometry, quantum ...

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

What is the Big Crunch theory? This theory is highly debated, but could be what happens when you hit the rewind button of the ...

“So the cosmological lithium problem remains.” The result doesn’t surprise Brian Fields , a theoretical astrophysicist at the University of Illinois Urbana-Champaign.

Efforts to reconcile this "cosmological constant problem" include invoking scalar fields, modified gravity theories, or multiverse scenarios. One puzzle, ...

And when we take our measurements and we combine them with other results from other collaborations from other types of tracers, we start to see some very strong hints that dark energy might not be a ...

For decades, physicists have agreed that the universe is expanding at a fixed rate of acceleration, a cosmological constant known as lambda that has been interpreted as the push of dark energy.But ...

Cracks in cosmological theory: ... which is called the Hubble constant, mysteriously diverged. ... somebody might say that is a problem” Reiss said.

The problem with the Drake equation was that it wasn’t really ... The cosmological constant was one of the variables Sorini’s team manipulated to determine if we are living in a universe ...

Its first BAO results are intriguing – the data alone is still consistent with a cosmological constant, but with hints of a possible time-varying dark energy when combined with other data sources.

We expect fluctuations in the quantum fields to produce such a constant energy density, resulting in an “energy of the vacuum” that behaves exactly like a cosmological constant. Problem is ...

Most importantly, when the formula is applied to the entire universe, it yields a value for ℏ' that offers a potential solution to the cosmological constant problem.
