After an intergalactic search lasting more than two decades, an Australian-led team of scientists says it's finally found the universe's "missing matter", solving a mystery that has long stumped astronomers.
Astronomy is full of missing stuff. Most of the universe is understood to be "dark matter" and "dark energy", which nobody has ever directly seen. But even more of a mystery for astronomers was that they couldn't find about half the ordinary matter in the universe."It's been a true embarrassment that we haven't been able to find it," said Professor Xavier Prochaska, an astronomer from the University of California, Santa Cruz.
Just like a prism spreads light into a rainbow of colours, each with a different frequency, the missing matter in the universe spreads the FRBs out into different frequencies. The team used the CSIRO's Australian Square Kilometre Array Pathfinder , — an array of 36 radio telescopes in the Mid West of Western Australia. Combined, the dishes equate to a single radio telescope with a 4,000 square metre dish.They have the ability to look at a huge area of the sky in high resolution. That means without knowing where an FRB would come from, they were able to capture it, and analyse exactly how spread out each wavelength in it was.
The density of the missing matter was calculated using the distance of the fast radio burst from Earth and the delay between the wavelengths of the FRB.The discovery still leaves much of the universe undetected. About 85 per cent of its matter is thought to be "dark matter" — that which is undetectable using ordinary methods.
FYI this isn’t about dark matter
Go CSIRO. So proud Australian scientists are leading the world in astronomy.
Well, that’s a relief 😅
Down the back if the lounge cushions
. Wr also watched as man landed on the moon, played golf, hooned around in a beach buggy and flew back to Earth. That turned out to be BS as well.. .
Where was it moved to? Or was it there all along and they just worked out how to detect it? Words matter
FBR's is creators frequency network, a man made depullulation of evolvement. Fathomable expansion, that's left behind big bangs and exploding black holes in a time unfathomable. Stop darker tilts. Lights spectrum ➕ periodic law through varients of positivity. LSD needed guides
I love how when scientists discover something amazing they always say there's more to learn. Unlike certain members of society that subscribe to ancient books written by goat herders.
