Surprisingly, we found that even significantly higher dark energy densities would still be compatible with life, suggesting ...

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 ...

This, in a nutshell, is the cosmological constant problem. While the universe is observed to be incredibly big, physicists calculate that it must be tinier than a proton. June 15, 2025 e-Paper ...

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.

This is known as the cosmological constant problem. Put another way, particle physicist’s models predict that what we think of as “nothing” should have some weight, Turner says.

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.

Was Albert Einstein wrong about the cosmological constant? Expansion Mirage. A new theoretical physics study suggests that the expansion of the universe may be an illusion — a controversial new ...

The cosmological constant, which explains how and why the universe is expanding, has been previously described by astrophysicists as “the worst prediction in the history of physics” due to its ...
