Is the 'fine-tuned universe' an illusion?

For decades physicists have been perplexed about why our cosmos appears to have been precisely tuned to foster intelligent life. It is widely thought that if the values of certain physical parameters, such as the masses ...

Astronomers trace galaxy flows across 700 million light years

Everything in our universe moves, but the timescales needed to see motion are often vastly greater than human lifetimes. In a major new study, a team of astronomers from the University of Hawaiʻi Institute for Astronomy ...

ESA determines new 'space time'

Since November 2021, ESA's satellites and ground stations have been running on a newly defined, incredibly precise "ESOC time." Measured by two atomic clocks in the basement of the ESOC mission control center in Germany, ...

Superhorizon modes can explain Hubble tension

A research team led by Dr. Prabhakar Tiwari from the National Astronomical Observatories of Chinese Academy of Sciences (NAOC) has found that superhorizon modes could explain the observed Hubble tension.

Stress for couples on Universal Credit as living costs soar

Fluctuations in income from month to month and low levels of out of work benefits are placing significant stress and strain on couples with joint claims for Universal Credit, according to researchers from the Universities ...

Towards quantum simulation of false vacuum decay

Phase transitions are everywhere, ranging from water boiling to snowflakes melting, and from magnetic transitions in solids to cosmological phase transitions in the early universe. Particularly intriguing are quantum phase ...

The quantum field theory on which the everyday world supervenes

The laws of physics underlying everyday life are, at one level of description, completely known, and can be summarized in a single elegant—if quite complex—equation. That's the claim physicist Sean Carroll, an SFI Fractal ...
