Our Universe was ‘pre-heated’ in its early moments, according to a new study from the International Centre of Radio Astronomy Research (ICRAR), challenging assumptions it emerged from an ultracold state. The discovery was made as astronomers hunted for an elusive signal from the Epoch of Reionization – the time when the first suns began to fire up about a billion …

In May 2019, astronomers picked up something strange in the fabric of spacetime. The LIGO and Virgo detectors recorded a gravitational wave that lasted just one-tenth of a second. The signal, known as GW190521, was unusual straight away because it didn’t look like the normal “chirps” usually produced when two black holes orbit one another before colliding. Instead, it sounded …

Strike a match, watch the flare, and you’re tapping into something humans have relied on for at least 245,000 years. But despite its primal aura, fire is almost impossibly rare. It’s not just that Earth is the only place we’ve seen it — it may be the only …

Back in 2019, the gravitational wave observatories LIGO and Virgo detected major ripples in spacetime. While astronomers generally agree that the event, dubbed GW190521, was the result of two black holes colliding, a team of researchers at the Chinese Academy of Sciences has proposed a far more eyebrow-raising explanation. As detailed in a yet-to-be-peer-reviewed paper, first spotted by ScienceAlert, the …

New “magic number” could redefine origins of everything in our Universe  Neowin Source link

Are we living in a simulation? Well, the jury’s out on that one. But humans do create simulations all the time. In fact, the Euclid Consortium, the international group managing the European Space Agency’s Euclid space telescope, just published the world’s most extensive simulation of the universe. It maps an astonishing 3.4 billion galaxies and tracks the gravitational interactions of …

The Big Bang may have actually been the explosive rebound of a collapsing black hole – one which our entire Universe could still be inside of. That’s the claim of a new study led by Enrique Gaztañaga at the University of Portsmouth. The paper suggests the Big Bang was actually a ‘Big Bounce’, when matter falling into a giant black …

A giant structure around 9.2 billion light-years from Earth and measuring around 1.3 billion light-years across is raising huge questions about our understanding of the universe. If the structure persists with continued observations and analysis, it could shake up the cosmological principle, and the idea that the universe is the same in all directions. The more we learn about the …
