Realme's new phone provides users with significant features by supporting some hand movement capabilities.

According to the product page on Realme's official website , the GT5 Pro uses its 32-megapixel selfie camera to recognize your palm. When you place your palm facing the camera, the screen unlocks and the screen turns on automatically when you move your hand away. This feature seems to support an ultrasonic proximity sensor, most likely made by Elliptic Labs.

Like LG models, Realme supports multiple gestures. By gathering your fingers to a point, the list of recent programs appears, and you can browse the recent programs by moving your finger to the left or right.

Realme's flagship phone is equipped with the latest Qualcomm Snapdragon 8 generation 3 processor, a 6.78-inch Chinese BOE curved screen (2780 x 1268 resolution, 144 Hz refresh rate and 4500 nits maximum brightness) and 100 W fast charging with battery capacity. It supports 5400 mAh.

Realme GT5 Pro has a USB 3.2 Type-C port, two speakers and an infrared remote control sensor. This phone also houses a three-layer cooling vapor chamber. The GT5 Pro is also IP64 certified for dust and water resistance.

The Realme phone is equipped with a 50-megapixel main camera (with a Sony LYT-808 sensor like the OnePlus 12 ), an 8-megapixel ultra-wide camera and a 50-megapixel telephoto camera with a 3x periscope lens (with a Sony IMX890 sensor like the Oppo Find X6 ). .

The price of the Realme phone in China is about $460 for the 12GB RAM and 256GB storage model, and $590 for the 16GB RAM and 1TB storage model.

According to DSCC , although it seems that Samsung will lose a significant amount of its share in the fourth quarter of this year, but the record sales of foldable phones in the third quarter of this year thanks to the release of the Galaxy Z Fold 5 and Galaxy Z Flip phones. 5 And of course, the increase in competition in the Chinese market has broken.

The share of the manufacturer of all types of Samsung phones has decreased from 86% last year to 72%, but despite this, the largest share of the third quarter of this year was recorded in the name of the Korean giant of the technology industry. The makers of Huawei phones and Honor phones are in the second and third positions with 9 and 8 percent of the market share respectively.

Although the sales of foldable phones are expected to increase by 47% in the fourth quarter of this year compared to the same period last year, it is likely to experience a decrease of 35% compared to the third quarter of this year. Reports indicate that the share of the Samsung brand will reach 42% compared to 83% last year with a heavy fall.

Huawei and Honor say that they will occupy 21 and 19 percent of the market share in the future. According to the forecasts, Huawei Mate X5 will take 15% of the market share after Galaxy Z Flip 5, which has a share of 22%. Galaxy Z Fold 5 will be in fourth place after Honor Magic V2 with 12% of the market share.

The top five models this year will most likely be the Galaxy Z Flip 5, Galaxy Z Fold 5, Galaxy Z Flip 4 , Honor Magic V2 and Huawei Mate X5.

It is predicted that the sales of folding phones in 2023 will reach 15.6 million units, increasing by 23% compared to 2022.

What if a stray star collided with the solar system?

Some stars wander in space and may disrupt star systems by passing by them; But what is the probability of this happening to the earth?

Stars are gravitationally bound to their galaxy and move in harmony with their surroundings; But sometimes these connections are lost. For example, if a star gets too close to a supermassive black hole, the black hole can repel it as a wandering star in space; But what happens if these stray stars approach Earth? In response, it should be said that although this is not very likely, the probability is not zero either.

After a few billion years, our solar system has reached a relatively stable state. The planets move as they should and the sun is in their center; But if another star gets too close, the invisible gravitational bonds that hold everything together will break.

Earth is a small planet and its mass reaches three millionth of the mass of the Sun. The fate of our planet depends on the Sun and its gravity, and if another star disrupts this fatal harmony, the Earth will be placed in a new gravitational pattern.

We know that the predictable stability of our solar system will not last forever. The sun continues on its evolutionary path and will eventually reach a high luminosity within the next few billion years. Earth is near the inner edge of the life belt, and if it moves a little closer to the Sun, the balance that keeps liquid water on its surface will be lost.

There is only a one percent chance of encountering a stray star in about a billion years, but what are the consequences of this? Is the earth leaving the life belt?

Earth can maintain its habitable surface conditions for another billion years. Although the evolution of planetary orbits is strongly influenced by extreme eccentricities, a stray star can have drastic consequences for their orbits.

In one scenario, the stray star could destroy all eight planets in the solar system

If a passing star approaches us, our solar system will no longer be a closed system. Stray stars are often called intergalactic stars or superfast stars because their trajectory eventually causes them to be ejected from the Milky Way.

Kappa Cassiopeia, for example, is a star 4,000 light-years away and will never approach us. Other stars, such as Vanderbilt University's 675 Wandering Stars, discovered in 2012, were ejected after interacting with the Milky Way's supermassive black hole and will not be traveling close to Earth.

The researchers ran mass N simulations to investigate possible outputs for Earth. They started with eight solar system planets and added a stray star to their model. They also matched the mass of the simulated stray stars with the mass of the nearby star. They also investigated the initial velocity of the wandering stars relative to the surrounding environment. They then simulated different velocities and trajectories of the star to arrive at a range of Earth-related outputs. In total, the researchers achieved 12,000 simulations.

According to the authors, if a star is located at a distance of 100 AU from the Sun, more than 95% of all eight planets in the solar system will survive. A measure called angular momentum loss (AMD) due to the star's passage can determine what happens next. AMD is a measure of planetary system orbital excitation and its long-term stability; But what will happen if one of the planets of the solar system is lost?

Researchers' simulations led to divergent results. Mercury is the most vulnerable planet and according to the simulation, it will be destroyed by impact with the Sun. Other results are: the collision of the Earth with Venus, the expulsion of the ice giants Uranus and Neptune, remaining only Earth and Jupiter or only Jupiter. In an apocalyptic outcome, all eight planets are ejected from the solar system.

Other results are less significant. Based on these results, all eight planets remain unchanged, undergo slight declination or, in the third scenario, become severely declinated. Although eight planets survive in most simulations, this survival can have different meanings. Although the planets remain in the solar system and are gravitationally connected to the sun, their orbits will be severely disrupted. The orbit of some of them can even be thrown into the Oort cloud .

The researchers also listed ten examples of the most likely outcomes for planetary destruction. They write:

The possibilities are as follows:Mercury's collision with the Sun (2.54 percent)Mars collision with the sun (1.21 percent)Collision of Venus with another planet (1.17%)Expulsion of Uranus (1.06 percent)Expulsion of Neptune (0.81 percent)Mercury collision with another planet (0.80 percent)Earth collision with another planet (0.48 percent)Saturn rejection (0.32 percent)Mars collision with another planet (0.27 percent)Earth collision with the sun (0.24 percent)

When it comes to rejected planets, Uranus and Neptune are the most obvious examples. Of course, this result is not surprising because these planets have a weaker gravitational bond with the Sun due to their distance. It is also not surprising that Mercury will also collide with the Sun, because due to its low mass, it faces a higher risk of being deflected by the transit of a wandering star.

In relation to land, a wide range of possible outcomes is suggested. According to the above list, the probability of Earth colliding with another planet is 0.48%; But another fate awaits the earth, which is not so pleasant: exile to the Everett Cloud.

Another strange result of the simulations is also worth noting: Earth getting trapped by the wandering star. According to this simulation, the wandering star is slightly less massive than the Sun and is approaching our solar system at a relatively low speed.

If the Earth is trapped by a stray star, it will leave the solar system

Based on the above conclusion, the Earth leaves the Sun and escapes with the passing star; while the other six planets collide with the sun. Meanwhile, Jupiter is the only survivor, and of course this result is not strange, because Jupiter is the heaviest planet in the solar system.

The aforementioned article considers a wide range of possibilities, including the collision of the moon with the earth, the moon and the earth falling into the trap of a stray star, and even the destruction of all the planets and their moons; But the probability of these occurrences is very small.

However, how could Earth remain habitable in such an encounter? If the Earth's orbit changes, the planet will definitely get colder or warmer.

There are more possible destinies. Earth, for example, can survive as a wandering planet for a million years or more before its surface freezes. or maintain its viability by trapping the wandering star in a new combination.

Finally, the probability of a star passing through the distance of 100 astronomical units is very small, and according to simulations, even if this happens, all eight planets will be saved, although their orbit will be slightly different from the current orbit. In general, despite the variety of evolutionary paths, the current state of our solar system will most likely not change.

Instagram was accused of providing a platform for sexual abuse of children

The New Mexico Attorney General has filed a new lawsuit against Meta, calling Facebook and Instagram a breeding ground for sex offenders.

According to the Wall Street Journal , a new complaint has been filed by the New Mexico Attorney General against Meta. The lawsuit alleges that Meta and its CEO, Mark Zuckerberg , have allowed Facebook and Instagram to become "platforms for child sexual abusers." According to the complaint, filed in state court on Tuesday, the meta-algorithms recommend sexual content to children.

The New Mexico Attorney General's Office conducted an investigation that included the creation of a number of fake and test profiles on Facebook and Instagram; Accounts that claimed to be children or teenagers. As a result of this investigation, not only did they find inappropriate recommendations for each of the prey accounts (including accounts that publicly posted adult pornography), but it was confirmed that they also attracted sexual harassers and predators.

A test account claiming to be a 13-year-old girl gained more than 6,700 followers, most of whom were male adults. Some accounts asked the user to contact them privately or meet them offline.

According to the complaint filed, the fake account of the 13-year-old girl received "messages full of sexual images and videos". This account reported many posts and accounts; But Meta responded that it found no violations of community standards.

The complaint states: "Meta, Facebook and Instagram platforms are breeding grounds for criminals who prey on children for human trafficking, distribution of sexual images, neglect and prostitution. Teenagers and children can easily register without any restrictions and there is no age verification process for them. It also sends inappropriate meta and content to them."

The Wall Street Journal recently published findings on how Facebook enables and promotes groups that share child sexual abuse content. Based on this, Meta developed terms, phrases and emojis related to child safety and used them to identify criminal networks. It also stopped recommending groups with members "behaving in a suspicious manner."

A Meta spokesperson told the Wall Street Journal: "We use advanced technology to root out abusers, hire child safety experts, report content to the National Center for Missing and Exploited Children, and share information with other companies and law enforcement agencies. "We share with state attorneys general."

New Mexico Attorney General Raul Torres claimed that Meta downplays the dangers children face on the platform and continues to prioritize engagement and advertising revenue over the safety of the most vulnerable members of society.

Meta is currently facing dozens of lawsuits alleging that its platform harms the mental health of children. Zuckerberg and the CEOs of other major social platforms are also set to testify before the US Senate in January about their failure to protect children.
