Move over, multiverse – a mirror universe may be a more realistic explanation.

If dark energy isn’t constant, we may need to rewrite the standard model of cosmology.
Some of the earliest galaxies found with JWST are also the brightest. That’s a problem for our ideas about the universe.
We may be on the cusp of finally breaking the standard model of cosmology.
The Hubble tension has been described as a “crisis” for cosmology. Can it be resolved?
A new series delves into the big questions surrounding the nature of our universe.
Right now, it looks like cosmology is at a tipping point.
If some of the laws of physics were only infinitesimally different, we would simply not exist. It almost looks like the universe itself was built for life. But how can that be?
Gravitational waves: are they worth the hype?
In about 10100 years, the universe will have passed away in a tragic ‘heat death’. But don’t despair, eventually random conscious brains may pop out in empty space to shake things up.
The idea that our universe is just one in a ‘multiverse’ of parallel universes is increasingly gathering attention from cosmologists. But can we ever test the theory?
A new model suggests that elliptical galaxies are more likely to be habitable than spiral galaxies like our own. Does that mean we’re a freak event and elsewhere is teeming with life?
