Do we live in a giant void? That could solve the puzzle of the universe's expansion, research suggests

One of the biggest mysteries in cosmology is the rate at which the universe is expanding. This can be predicted using the standard model of cosmology, also known as Lambda-cold dark matter (ΛCDM). This model is based on detailed ...

Physicists answer question of Supergalactic Plane's absent spiral galaxies

Astrophysicists say they have found an answer to why spiral galaxies like our own Milky Way are largely missing from a part of our local universe called the Supergalactic Plane.

The universe is expanding faster than theory predicts—physicists are trying to explain the mismatch

Astronomers have known for decades that the universe is expanding. When they use telescopes to observe faraway galaxies, they see that these galaxies are moving away from Earth.

If you account for the Laniakea supercluster, the Hubble tension might be even larger

One of the great unsolved mysteries of cosmology is known as the Hubble tension. It stems from our inability to pin down the precise rate of cosmic expansion. There are several ways to calculate this expansion, from observing ...

Researchers find gravitational lensing has significant effect on cosmic birefringence

Future missions will be able to find signatures of violating the parity-symmetry in the cosmic microwave background polarization more accurately after a pair of researchers has managed to take into account the gravitational ...

New telescopes to study the aftermath of the Big Bang

Astronomers are currently pushing the frontiers of astronomy. At this very moment, observatories like the James Webb Space Telescope (JWST) are visualizing the earliest stars and galaxies in the universe, which formed during ...

Astronomers carry out largest ever cosmological computer simulation

An international team of astronomers has carried out what is believed to be the largest ever cosmological computer simulation, tracking not only dark but also ordinary matter (such as planets, stars and galaxies), giving ...

Black holes could come in 'perfect pairs' in an ever expanding universe

Researchers from the University of Southampton, together with colleagues from the universities of Cambridge and Barcelona, have shown it's theoretically possible for black holes to exist in perfectly balanced pairs—held in ...

Do we live in a computer simulation like in The Matrix? Proposed new law of physics backs up the idea

The simulated universe theory implies that our universe, with all its galaxies, planets and life forms, is a meticulously programmed computer simulation. In this scenario, the physical laws governing our reality are simply ...
