Strange galaxy observations challenge ideas about dark matter
Confusing observations of distant galaxies change what cosmologists know about the universe every day. The strange substance called dark matter may never have existed. Here are all the details.

That’s one of the possible conclusions of a new study published June 20 in The Astrophysical Journal Letters. The finding “raises questions of an extraordinarily fundamental nature,” said astronomer Richard Brent Tully of the University of Hawaii at Manoa, who was not involved in the study. Astronomers suspected dark matter existed because of the way stars and other visible material at the visible edge of the galaxy rotate. The rotation speeds of objects far from the galactic center are the bright stars seen in telescopes. article much higher than it should be considering the amount. According to physicists’ current understanding of gravity, this means that a huge reservoir of invisible matter must be tugging on these stars.
The new results are based on the fact that massive objects distort the fabric of space and time. Galaxies consist of enormous amounts of visible stars, gas and dust, as well as – according to theory – a huge halo of invisible dark matter. This means that light will be bent and distorted as it passes by a galaxy; This is an effect known as gravitational lensing. Knowing this, astronomer Tobias Mistele and his colleagues from Case Western Reserve University in Cleveland revealed through their research that dark matter, which was thought to exist from the beginning, may not actually exist. So we could be wrong about everything we know.

Crisis Grows at Boeing; 17 Thousand People Will Be Dismissed
The crisis is growing in Boeing, which has recently come to the fore with successive failure news; The company announced that it would lay off 17 thousand people.

The crisis is growing in Boeing, which has recently come to the fore with successive failure news; The company announced that it would lay off 17 thousand people.
Boeing, which was once one of America’s most successful and prestigious companies, has now turned into one of the most controversial and unreliable companies in the aviation industry. On the one hand, security risks and unreliable inspection practices in the aircraft produced by the company were brought to the agenda, and on the other hand, the company’s space tourism dreams were dashed. Starliner, the spacecraft developed by Boeing with great hopes, failed in its first manned mission to the International Space Station.
Starliner, which had problems returning after carrying the astronauts to the International Space Station, finally returned alone without taking the astronauts after being stranded there for months. SpaceX brought back the astronauts who were stranded on the ISS. This entire fiasco caused not only the Starliner project, but also Boeing a great loss of prestige. These consecutive fiascos have put the company in a major crisis today. So much so that the company had to make one of the biggest layoff decisions in its history.
Boeing announced this week that it would lay off 17 thousand people. announced. This equates to 10 percent of the company’s total workforce, which is something we rarely see such a significant downsizing for a company of this size. Therefore, it also reveals the extent of the crisis in the company.
These layoffs are said to be linked not only to the Starliner debacle and the decline in confidence in the company’s aircraft, but also to discord within the company. Thousands of people from the engineers union, which Boeing management cannot agree with, are currently on strike. This put the company, which was already going through a difficult period, into an even bigger crisis. There is a possibility that the current layoff decision will deepen this crisis even further. Because this decision will further anger the union members who are on strike.

Boeing May Scrap the Starliner Project
Boeing may give up hope on the Starliner spacecraft, which is halfway through its first real mission, and completely scrap the project on which it spent billions of dollars.

Boeing may give up hope on the Starliner spacecraft, which is halfway through its first real mission, and completely scrap the project on which it spent billions of dollars.
Boeing, the aviation company that aims to compete with companies such as SpaceX and Blue Origin with the space shuttles it has developed, came very close to making this dream a reality in June. The space shuttle Starliner, which Boeing has been working on for a long time, successfully completed its journey to the International Space Station on June 6 and delivered the two astronauts it carried to their places of duty in low Earth orbit. Boeing would finally receive the reward of its years of efforts and billions of dollars of investment…
Until preparations began for the return of the Starliner. When NASA began conducting tests for the return, it realized that its Starliner was not fit for return. Having done its best to make Starliner suitable for return in the past three months, NASA finally threw in the towel last week and admitted that it was unable to bring back the astronauts Starliner had taken. Moreover, SpaceX’s space shuttle would “rescue” the astronauts who were stranded on the ISS for months because of Boeing’s space shuttle.
This adventure, in which Boeing set out with the dream of participating in the space race, turned into one of the biggest fiascos of recent years. This crisis, which caused Boeing to seriously lose its prestige, also shook the confidence in the company’s space vehicles. So much so that this project may go to waste altogether.
This week, Boeing executives were asked whether the Starliner project would continue despite this setback. The Boeing executive’s illegal answer to this question did not go unnoticed. If there was no truth behind the rumors, the Boeing executive would definitely say that such a situation is out of the question and emphasize their determination on this project. But it didn’t happen that way. Boeing executive refuses to make a statement in this direction avoided. This showed that the company may have to completely abandon this project, for which it actually spent 1.6 billion dollars.
As if this were not enough, Boeing’s other projects at NASA are now also being reviewed. Certain parts of the SLS, which will be used in NASA’s flight to the Moon, were also produced by Boeing. New reports that have emerged now show that Boeing is both far behind the schedule and already over its budget in these projects.

Starliner astronauts will return in February
After more than two months of testing and discussions, NASA allowed astronauts Butch Wilmore and Suni Williams to return home aboard the SpaceX Crew Dragon in February 2025. Here are all the details.

After more than two months of testing and discussions, NASA allowed astronauts Butch Wilmore and Suni Williams to return home aboard the SpaceX Crew Dragon in February 2025. Here are all the details.
In addition to the Starliner astronauts, it was also decided that the Boeing Starliner, on which they flew to the International Space Station in June, would return without a crew. Steve Stich, NASA’s Commercial Crew Program manager, said at a news conference Saturday that “there’s a lot of uncertainty” about predictions that the spacecraft will move forward with a crewed return flight. The current plan is for Starliner’s first crew to return aboard SpaceX’s Crew-9, which is scheduled to launch to the ISS at the end of September. Crew-9 was originally supposed to carry four crew members, but will have to proceed with two crew members on the return trip to make room for Wilmore and Williams. The spacecraft in question also includes spacesuits for astronauts. By the time Wilmore and Williams depart, the duo will have been on the space station for about eight months. Starliner flight testing was only supposed to last just over a week, but plans were dragged out.
The next step is to prepare the spacecraft for docking and complete uncrewed flight testing. The agency plans to conduct the second part of its preparatory review of the process next week. He expects the landing to take place early next month. “We are changing our planned separation order and will review these issues in the readiness review,” Stich said. “A simplified way to get away from the station a little faster.” separation “We will apply the technique.”
