(TMU) – The shape of the universe is hard to get one’s head around, not only as a theoretical concept but as a mathematical one, yet it remains as one of the most important unanswered questions in physics. Determining the geometry of the universe, many scientists believe, will be fundamental to solving the mysteries of the cosmos.
New measurements of dark energy and cosmic expansion collected by a team of astronomers at the University of Portsmouth constitute the most precise data yet in this intellectual quest. This recently published data suggests the universe is spatially flat – not shaped like a bubble.
The team used a new method combining the study of cosmic voids (immense bubbles of space containing only a few galaxies) and relics of sound from the very early Universe, which scientists refer to as baryon acoustic oscillations (BAO). Previously, scientists attempting to chart cosmic expansion and dark energy used distant supernovae as beacons of measurement in the unfathomable depths of space.
The new method, helmed by the Sloan Digital Sky Survey for over a decade, gathered data from over a million galaxies and quasars. The results seemingly accomplished two interrelated theoretical hurdles: 1) disconfirmed measurements of the cosmic microwave background (CMB) by the Planck satellite, which suggested a bubble-like spherical universe, and 2) confirmed the (Hubble) model of a cosmological constant dark energy, which suggests a flat universe.
Additionally, the fresh data will likely help write a new chapter in our understanding of the evolution of dark energy and its effect on the universe.
“This result shows the power of galaxy surveys to pin down the amount of dark energy and how it evolved over the last billion years,” wrote Portsmouth cosmologist Seshadri Nadathur in a press release. “We’re making really precise measurements now and the data is going to get even better with new surveys coming online very soon.”
It should be noted that a “flat” universe doesn’t mean what your mind might visually conjure. Of the ten or more suggested shapes of the universe over the decades, they belong to three major geometric categories: flat, round, and hyperbolic. So “flat” is actually an umbrella term that could refer to a number of different topologies, including the “torus.”
In other words, even if our universe is flat, that doesn’t rule out it being bent into an involutional, hyperdynamic, donut-like shape known as the torus.
The question of whether the universe is spatially flat or round is one of the most contested questions in physics, right up there with whether the cosmos are “open” or “closed”. Eerily, some cosmologists say if recent measurements confirm that the universe is both flat AND “closed,” this would raise the prospect of physical reality wrapping around itself in an infinite loop.
But that’s for another day and another cup of coffee.
Jeff Bezos Thanks Amazon Workers And Customers For Paying For His Flight To Space
The billionaire space race chalked up one more ignoble milestone on July 20 when the world’s richest man, Jeff Bezos, boarded a reusable rocket his company Blue Origin built and funded, flew to the edge of space for a moment of weightlessness, and came back down to earth.
You can watch the flight and learn more about the journey here.
The Amazon founder has faced withering criticism for accumulating his massive fortune on the backs of an exploited workforce that is subject to harsh working conditions and low pay in warehouses or Fulfillment Centers where staffers must urinate in water bottles in order to meet their quotas.
In his press conference following the launch, Bezos thanked that same workforce for helping him to shoot himself into space in a move that many critics have described as a simple “joyride.”
“I want to thank every Amazon employee and every Amazon customer because you guys paid for this,” he told the crowd, which responded with laughter. “Seriously, for every Amazon customer out there and every employee thank you from the bottom of my heart very much. It’s very appreciated.”
Critics on Twitter responded with derision, noting that Bezos was able to enjoy the trip at the expense of his hard-working employees.
“Thing is, employers are supposed to pay their employees, not the other way around, but that’s basically how Amazon works,” one user tweeted.
While another tweeter asked: “Maybe they’re searching space for signs of a livable wage or a way to pay their fair share of taxes?”
On Tuesday, Bezos blasted off in the sub-orbital New Shepard rocket from Texas. The date for the launch was chosen to coincide with the 52nd anniversary of the Apollo 11 moon landing.
Members of the crew, which included his brother mark and 82-year-old female astronaut Wally Funk, brought a number of historic items on the flight, including a piece of canvas from the conceptual plane originally flown by the Wright brothers, the goggles Amelia Earhart used to fly across the Atlantic, and a brass medal made from the first hot air balloon which flew in 1783.
Keanu Reeves Praised As Video of Him Offering Seat to Lady in Subway Resurfaces
Keanu Reeves is an actor who has long been loved by audiences —and not necessarily due to his acting skills, but due to how nice the John Wick star is.
And now, Reeves is once again earning praise as a “true gentleman” after resurfaced video footage shows Reeves giving up his seat on the subway.
The clip was shared by Instagram film fan account Cinemonkeys where it has since earned nearly 45,000 likes.
The video footage dates back to 2011, when it was shared on YouTube by a user of the video-sharing platform.
At the time, Reeves was already a superstar riding on the fame he earned from the Matrix, Speed, and a number of other blockbuster hits.
When Reeves notices a woman carrying a heavy bag, he quickly points to his seat and asks if she would like to sit. The woman accepts and Reeves gets up without hesitating to let her take his seat.
Reeves, ever the model citizen, then stands and holds onto a subway pole while carrying his bag.
The video has since been watched over 27 million times and was even cited in a 2019 Time magazine profile of the actor describing Reeves as the “soul mate” of the internet.
The resurfacing of the clip on Instagram once again impressed users of the platform.
“This human being’s soul honestly shines so bright,” wrote one user.
“OMG I love him in every single way,” another person commented.
“His kindness knows no bounds,” commented someone else.
Keanu is set to reprise his role as Neo in the upcoming fourth Matrix film directed and written by Lana Wachowski, who co-directed the earlier trilogy with her sister Lilly. He will also return to the silver screen in John Wick: Chapter 4, which will be released in 2022.
Drunk Man Rescues Injured Baby Bird By Sending It To Animal Shelter… In An Uber
An injured baby bird received a new lease on life after a young man who was inebriated had the good sense to send the little creature to an animal shelter because he and his friends were too drunk to drive.
In the Summer of 2019, a small lesser goldfinch suddenly appeared by itself at the Wildlife Rehabilitation Center of Northern Utah. The center’s chairman, Buz Marthaler, was notified by a volunteer who sent him a photo.
“It was a picture of this bird, and it had come by Uber,” Marthaler told FOX13. “It was just crazy.”
As it turns out, the tiny bird – which was only two weeks old – indeed rolled up to the site by its lonesome, the sole passenger in an Uber vehicle called by concerned citizens who found the injured creature.
Among those good Samaritans was Tim Crowley, who had been “day drinking” on that Saturday before he and his buddies witnessed the little bird fall from the sky.
“Impromptu, sitting in some camp chairs, hanging out, having a few drinks when we had a visitor fall out of the sky,” he explained.
Crowley then snapped a photo of the bird and sent it to the WRCNU, which instructed him to immediately bring the bird in. However, the group obviously couldn’t drive since they had been guzzling booze all day.
So Crowley decided he’d hail a cab for the creature.
“At first it was a joke, like, ‘Hey, maybe we should just call Uber!’” he said. “Then we were like, ‘No, really. Why not? We’re paying them.’”
As it turns out, the bird – since named “Petey Uber” by staff at the rescue center – likely would have perished if not for Crowley’s quick thinking.
Marthaler remains impressed by Crowley’s move and shared the news on its Facebook page.
“While we feel we’ve seen it all and can’t be amazed by anything, there is always someone out there to prove us wrong,” the shelter’s post read. “Thank you to the rescuer who helped this little one get the care it needed in a timely manner and thank you for keeping yourself safe and others on the road safe as well.”
