Cosmoboffins think grav waves hold the key to sorting out the disputed Hubble Constant

Scientists agree that the universe is expanding at an increasing rate, but by exactly how much is still an enigma. To measure the pace of expansion, slightly confusingly known as Hubble’s Constant because it's not actually constant, boffins need two bits of information. One is the speed at which an object is receding from …

The Register Lecture: Great gravitational waves! LIGO's next cosmic act

If you think the revolution in our understanding of the final frontier ignited by the discovery of gravitational waves in 2015 is over - think again. The Laser Interferometer Gravitational-Wave Observatory (LIGO) and interferometer pal Virgo caused a sensation when a team of more than 900 scientists detected gravitational …

Nebula spotted with more super-sized bodies than a gym on Jan 2nd

A freak nebula is teeming with gigantic stars, say scientists who now reckon these cosmic heavyweights may not be so rare after all. The Tarantula Nebula, also known as 30 Doradus or 30 Dor, located about 160,000 light years away, could contain a whopping 600 stars that are between 15 to 200 solar masses. Fabian Schneider, a …

Boffins on alert: Brace yourselves for huge gravitational wave coming within a decade

The most violent gravitational waves in the universe from supermassive black hole prangs will be detected to within ten years, according to research published on Monday. Gravitational waves were predicted by Albert Einstein and finally discovered in 2015, a century after his theory of general relativity was formalized. Ripples …

Swinburne Uni slings SGI, picks DellTel for new 4,140 core super

Australia's Swinburne University has signed up for a new supercomputer, to help spearhead efforts to detect gravitational waves. OzSTAR will be composed of Dell PowerEdge R740 servers each packing a single 18-core, 36-thread Xeon Gold 6140, a pair of NVIDIA Tesla P100 12GB GPUs and 192GB RAM. Eight of the 115 nodes in the …

ESA trying to 'bake, rattle and roll' gravity wave space probe

The European Space Agency is giving the LISA Pathfinder probe what it calls the “Bake, rattle and roll” treatment in the hope it teaches us how to make its successors even better. As the name suggests, LISA Pathfinder is a test mission for the planned three-vessel LISA space observatory, which will be positioned in a …

Let's grow a baby universe in a supercomputer, watch black holes collide

Physicists have created simulations that predict the rate at which gravitational waves from the collision of monstrous supermassive black holes may be detected. The results are due to be announced later today at the Royal Astronomical Society's National Astronomy Meeting. In a monumental discovery, gravitational waves were …

Gravitational waves: A new type of astronomy

The first time physicists announced that the Laser Interferometer Gravitational-wave Observatory (LIGO) had detected gravitational waves, on September 14, 2015, it was breaking news. The discovery coincided with the 100-year anniversary of Einstein's theory of General Relativity, which predicted the existence of gravitational …

LISA Pathfinder free fall test beats expectations

European Space Agency (ESA) boffins are tossing hats in the air as data from their LISA Pathfinder mission suggests its gravitational wave detection kit is going to live up to expectations. In the popular mind, LISA – the Laser Interferometer Space Antenna – has been upstaged by the Laser Interferometer Gravitational-wave …

LISA Pathfinder drops its gravity-wave-finding golden boxes

Its publicity thunder stolen by last week's announcement that the Laser Interferometry Gravitational-wave Observatory has seen the signal of the waves, the European Space Agency's LISA Pathfinder has passed what the agency calls a “major milestone”. The LISA – Laser Interferometer Space Antenna – Pathfinder is a proof-of- …

What would happen if Earth fell into a black hole?

Black holes have long been a source of much excitement and intrigue. And interest regarding black holes will surely grow now that gravitational waves have been discovered. Many of the questions I am asked regard how “true” science fiction concerning black holes might be, and whether worm holes, such as those featured in …

Boffins' gravitational wave detection hat trick blows open astronomy

Analysis A 15-year experiment using some of the most advanced technology known to Man has picked up the first detection of a gravitational wave, the first direct measurement of black holes, and the first direct evidence of binary black holes. It has also opened up an entirely new field of astronomy. The signal was picked up on …

LIGO boffins set to reveal grav-wave corker

After weeks of speculation, the stage is set for Laser Interferometer Gravitational-wave Observatory (LIGO) boffins to announce their findings. The LIGO Scientific Collaboration has briefly popped its head over the parapet to say it'll come clean about what it has (or hasn't) found on Thursday at the National Science …

Boffins tentatively fire up grav wave sniffer

European Space Agency (ESA) scientists have begun to fire up systems aboard the LISA Pathfinder spacecraft - designed to "test the technology needed to develop future space-borne gravitational wave detectors". The LISA (Laser Interferometer Space Antenna) Pathfinder is now on its way to its final destination orbiting Lagrange …

Europe launches search for Einstein's space-time ripples

The European Space Agency's LISA Pathfinder spacecraft is due to blast off tomorrow from Kourou, French Guiana, on its mission to "test the technology needed to develop future space-borne gravitational wave detectors". The launch date is not arbitrary. It celebrates the 100th anniversary of the publication of Albert Einstein's …

TOTAL DARKNESS lasted 550 MILLION years until the first STARS LIT UP

The first stars were formed much later than had been previously thought in the boffinry community, according to new maps of the universe's "ancient light" from the European Space Agency's Planck satellite. Astrophysicists have now calculated that the universe is roughly 13.8 billion years old, based on the light emitted by …

GRAV WAVE TSUNAMI boffinry BONANZA – the aftershock of the universe's Big Bang

Pics A team of astrophysicists has announced a sighting of gravitational waves – formed in the first trillionth of a trillionth of a trillionth of a second after the universe as we know it blinked into existence. The breakthrough discovery throws enormous weight behind the famous inflationary Big Bang theory. The boffins must be …
