Making use of some of the most powerful telescopes on the planet, astronomers have found an ancient remnant of the Big Bang. This small piece of pure material from the early universe may provide light on the processes and motivations behind the formation of various star and galaxy types.

Using telescopes at the W. M. Keck Obervatory in Hawaii, a team of astronomers led by Fred Robert and Michael Murphy of the Swinburne University of Technology in Australia discovered a cloud of gas leftover from the Big Bang that was hiding far out in the universe. Behind the cloud, the telescope also discovered a quasar, which is an extremely bright active galactic nucleus that emits a lot of energy.

Big black holes in little galaxies, rogue black holes and other behemoths could offer clues to cosmic evolution.

UNSW quantum engineers have developed a new amplifier that could help other scientists search for elusive dark matter particles.

The universe is expanding at an accelerating rate but Einstein’s theory of General Relativity and our knowledge of particle physics predict that this shouldn’t be happening. Most cosmologists pin their hopes on Dark Energy to solve the problem. But, as Claudia de Rham argues, Einstein’s theory of gravity is incorrect over cosmic scales, her new theory of Massive Gravity limits gravity’s force in this regime, explains why acceleration is happening, and eliminates the need for Dark Energy.

You can see Claudia de Rham live, debating in ‘Dark Energy and The Universe’ alongside Priya Natarajan and Chris Lintott and ‘Faster Than Light’ with Tim Maudlin and João Magueijo at the upcoming HowTheLightGetsIn Festival on May 24th-27th in Hay-on-Wye.

This change ‘is analogous to changing the direction of a new battleship in a few minutes,’ researcher Gerrit Schellenberger said.

I’ve spent too much time thinking about how portals could work in the real world and, yes, I guess that is somewhat weird, but well. From energy conservation to momentum conservation to moving portals, I have it all sorted out for you. And the cake is not a lie.

Inflation: The leading theory for the universe’s earliest moments, cosmic inflation, proposes that the universe underwent a brief period of exponential expansion an instant after the Big Bang. This process would have enlarged a minuscule volume of space to a tremendous size, much larger than our observable universe. Inflation neatly explains the flatness and uniformity we observe. But it also suggests that our entire observable universe is a tiny bubble in a vast inflated expanse.

Infinite replicas: If the universe is truly infinite, then everything that occurs within our observable universe must recur an infinite number of times beyond our cosmic horizon. The number of possible particle configurations in any finite volume is large but limited. In an infinite expanse, each configuration, no matter how unlikely, will be realized somewhere, and not just once but an infinite number of times. There would be infinite copies of our observable universe, infinite Milky Way galaxies, infinite Earths, and even infinite versions of you pondering this article. It’s a dizzying but inevitable consequence of an endless cosmos.
