There's space for everybody. ✨

Scientists observed for the first time that in the early Universe, time passed "five times slower". They analyzed data from quasar objects powered by "supermassive" black holes at the centers of the first galaxies, and used them to measure time shortly after the beginning of the Universe. "Looking back to a time when the Universe was just over a billion years old, we see that time seems to flow five times slower [just after the Big Bang]," says Lewis, lead author of the study published in the journal scientific Nature Astronomy. "If you were there, in this early universe, a second would seem like a second — but from our position, over 12 billion years in the future, that initial time seems to drag." "Thanks to Einstein, we know that time and space are intertwined, and since the beginning of time in the Big Bang singularity, the Universe has been expanding," he says. "This expansion of space means that our observations of the early Universe should appear much slower than how time flows today."

"In this paper, we established that this goes back to about a billion years after the Big Bang."

Time has been observed to pass more slowly in quasars in the early universe.

The observed time dilation comes as a consequence of Albert Einstein's theory of general relativity combined with the expansion of space. "At its core, this is another 'Einstein is right again' story," Geraint Lewis, a cosmologist at the University of Sydney, told Space. with.

🚨WARNING: 'Albert Einstein is right again'

Time dilation, brought about by the relativistic expansion of space, has resulted in the observed slowdown of 'clocks' in the early universe. Time appeared to move 5 times slower in the 1 billion years after the Big Bang, quasar 'clocks' reveal.

Ingenuity contacted its handlers on June 28 via its robotic partner, the Perseverance rover, NASA officials announced today (June 30). It was the first such communication since April 26, when the 1.8 kg helicopter went dark at the end of its 52nd flight over Mars' Jezero Crater.

"The part of Jezero Crater that the rover and helicopter are currently exploring has a lot of rough terrain, which makes communication breakdowns more likely," said Ingenuity team leader Josh Anderson of NASA's Jet Propulsion Laboratory at Southern California in a statement today.

O Ingenuity entrou em contato com seus manipuladores em 28 de junho por meio de seu parceiro robótico, o rover Perseverance , anunciaram os funcionários da NASA hoje (30 de junho). Foi a primeira comunicação desse tipo desde 26 de abril, quando o helicóptero de 1,8 kg escureceu no final de seu 52º voo no solo da cratera Jezero de Marte .

“A parte da Cratera Jezero que o rover e o helicóptero estão explorando atualmente tem muito terreno acidentado, o que torna as falhas de comunicação mais prováveis”, disse o líder da equipe Ingenuity, Josh Anderson, do Laboratório de Propulsão a Jato da NASA no sul da Califórnia, em um comunicado hoje .

The James Webb Space Telescope captured this near-infrared image on June 25, 2023.

The planet appears dark in this wavelength, as methane gas in its atmosphere absorbs sunlight. But the planet's ring system glows, as well as the moons Dione, Enceladus and Titan. Credits and sources: James Webb website

🚨ATTENTION: James Webb Space Telescope just released the image of Planet Saturn 🪐🔭

Halley's Comet is only seen every 76 years. Its last appearance was in 1986. The next perihelion will be on July 28, 2061 and it will be visible in practically the whole world. How old will you be on this date?

The findings, published in a Nature study on June 28, show that these black holes and their host galaxies are billions of times larger than our sun. Host galaxies measure 130 to 34 billion times the mass of our sun, while measurements of gas suggest that black holes measure 1.4 to 0.2 billion times the mass of our sun.

🚨ATTENTION: James Webb Space Telescope captured for the first time the light of the stars of two galaxies that host the black holes in active growth, less than a billion years after the Big Bang, the news just came out in a study released by the magazine NATURE.

What have scientists actually discovered? Scientists have observed faint ripples caused by the movement of black holes that gently stretch and compress everything in the universe.

They reported that they were able to "hear" so-called LOW FREQUENCY gravitational waves, which are the changes in the fabric of the universe created by huge objects moving and colliding in space.

In the most recent research, scientists were looking for waves at much lower frequencies. These slow ripples can take years or even decades to rise and fall, and they likely come from some of the largest objects in our universe: supermassive black holes billions of times the mass of our sun.

Galaxies across the universe are constantly colliding and merging. When this occurs, astronomer Szabolcs Marka of Columbia University, who was not involved in the study, explained that scientists think the massive black holes at the centers of these galaxies also come together and engage in a dance before collapsing into one another. other.

Black holes emit gravitational waves as they circulate in these pairs, known as binaries.

"Binaries of supermassive black holes, slowly and quietly orbiting each other, are the tenors and bass of the cosmic opera," said Marka.

No instrument on Earth could capture the ripples of these giants. So "we had to build a detector that was roughly the size of the galaxy," said NANOGrav researcher Michael Lam of the SETI Institute.

Gravitational waves, first predicted by Albert Einstein's theory of general relativity, are ripples in the fabric of space-time caused by the most energetic events in the cosmos, such as black hole mergers and neutron star collisions.

Detecting and studying these waves provides valuable insights into the fundamental nature of the universe. Scientists sometimes compare these ripples to the background music of the universe.

In early 2015, scientists used an experiment called LIGO to detect gravitational waves for the first time and showed that Einstein was right. But so far, these methods have only been able to capture waves at high frequencies, explained NANOGrav member Chiara Mingarelli, an astrophysicist at Yale University.

🚨BREAKING: Scientists have detected low-frequency gravitational waves for the first time, providing evidence of large-scale motion in the universe caused by black holes and neutron star collisions.

Gravitational waves are ripples in the fabric of space-time caused by the most energetic events in the cosmos. That's the news of the Big Announcement that scientists will unveil today at the conference.

🚨ATTENTION: Brazilian scientist Alysson Muotri could become the first scientist from Brazil to go to the International Space Station in November 2024.

Alysson Muotri is a professor and researcher at the University of California at San Diego, in the United States, where he has worked since 2008. He is also director of the Stem Cell Program at UCSD.

I kick blocks, 10 in 10 minutes.

Hold or HFSP

BTC doesn't care about our opinion.

No, ESG is shitcoin.

I'm just a pleb who likes astronomy, HOLD or HFSP.

If it climbs one place, should it climb all equally?

Don't we have several places that were on dry land and nowadays it's completely flooded?
