A photo collage has surfaced on Facebook in South Korea alongside various claims about the Sun’s distance from Earth and the formation of rainbows. Experts told AFP that the posts’ claims were misleading.
The claim was shared here on Facebook on March 21, 2021.
“If the Sun is really 150 million kilometres away, then the phenomenon where the Sun sits in front of clouds doesn’t make sense, because clouds can’t be that far away,” the Korean-language caption reads.
“The three elements that make up rainbows: Water, Light, Bowl-shaped reflective surface.
“Rainbows indirectly show the existence of a sky dome.”

The photos shared in the post purport to show the Sun partially covered by clouds and a rainbow over a valley. The English text superimposed on the image collage of the Sun reads: “If the Sun is 93 million miles away, How are clouds behind it?”
However, the claims are misleading, experts say.
The figures in the social media posts are approximately correct. The Sun is 149.60 million kilometres (92.92 million miles) away from Earth, according to NASA.
Clouds have been measured at altitudes of up to about 18 kilometres, as seen in this NASA infographic.
The photos that purport to show clouds appearing behind the Sun are the result of an optical illusion, according to Lee Jae-woo, an astronomer and professor at Seoul-based Sejong University.
Contacted by AFP, Lee said that the photos in the Facebook posts “appear to be this way because of a [light] contrast problem, making it seem as though thin clouds sitting in front of a very bright Sun are cut off or sitting behind.”
Lee said such a phenomenon is often caused by a camera, which is typically not capable of capturing brightness to the same level as a human eye.
“If the Sun was really closer to us than clouds, sunlight would spread radially, but because we are so far away from the Sun, rays appear to be parallel to us,” he said during a phone interview on March 29, 2021.
The posts also contain misleading information about rainbow formations, according to Professor Kim Yong-min, an optics expert at Dankook University’s physics department in South Korea.
He said rainbows are caused by reflections and refractions of light through surfaces that are not always bowl-shaped, adding that a rainbow appears curved because usually only half of it is visible.
“[The claim that rainbows show] the Earth is flat and that a dome exists on top is false,” he told AFP during a phone interview on March 30, 2021.
“Even in ancient Greece, [people] already knew the Earth was round by comparing the shadows of sticks in different places.”
Facebook-Meta Earns the ‘Worst Company of 2021’ Title in This Survey
Facebook parent Meta has been named the Worst Company of the Year (2021) by Yahoo Finance respondents. According to the publication, an “open-ended” survey was published on Yahoo Finance on December 4 and 5, where 1,541 respondents participated. Facebook received 8 percent of the write-in vote, but respondents were seemingly mad about the Robinhood trading app as well. Electric truck startup Nikola, which was named last year’s worst company by the same publication also faced respondents ire.
Yahoo Finance even highlights, “At the same time, some critics, including conservatives, say Facebook over-policed the platform’s speech and stifled their voices.” Critics also blame Facebook and other social media platforms for not curbing hate speech that led to Capitol Building riots.
However, around 30 percent of Yahoo Finance readers said that Facebook or Meta could redeem itself. One respondent suggested that the company could issue a formal apology for negligence and donate a sizable amount of its profits to a foundation to help reverse its harm.
On the other hand, respondents chose Microsoft as the Company of the Year (2021). The Satya Nadella-led company touched the trillion-mark this year and introduced notable upgrades. The most notable is the Windows 11 OS update that succeeds Windows 10.
Facebook pays 1.7 Cr fine to Russia after failing to delete content Moscow deems illegal
In the latest legal tussle with Russia over controversial social media regulation laws, Facebook paid 17 million roubles (Rs 1.7 Crore) for failing to remove content deemed illegal by Moscow. With a threat of potential larger fines looming, Facebook parent company Meta, owned by Mark Zuckerberg, is scheduled to face court next week over repeated violations of Russian legislation on content, Interfax News Agency reported. As per the latest updates, the social media giant could be fined a percentage of its annual revenue.
In October, Moscow sent state bailiffs to enforce the collection of 17 million roubles. Meanwhile, as per Interfax report citing a federal bailiffs’ database, on Sunday, there were more enforcement proceedings against the company. Apart from the popular social media app, Telegram has also paid 15 million roubles in fines for failing to comply with the Russian social media legislations that came into force in 2016.
Facebook pays $53k to Russia for refusing controversial social media laws
It is pertinent to mention that Facebook has locked horns with Moscow earlier in November, resulting in it paying 4 million roubles ($53,000) over its refusal to adhere to Russian data localisation laws, the Moscow Times reported. The Moscow court on November 25 had said that Facebook paid the fine levied in February, following which all proceedings against the US-based social media giant. The payment comes against the litigation filed against the company in 2018, alongside Twitter. The tech companies were also forced to pay an additional 3000 rubles ($40) for failing to comply with user data sharing rules as per the law. The Russian authorities have also previously blocked LinkedIn, owned by Microsoft, for failing to abide by the laws.
Russian social media laws
As per Moscow Times, under the Russian social media regulation laws, all foreign technology companies are required to store data related to Russian customers and users on servers located in Russia. Additionally, the Russian tech companies will also have to share encryption data with the federal authorities as well as record user calls, messages and civil society group conversation records. The apparatus is said to be a severe breach of privacy rights and unfettered back-door access to personal data that could be used to harass Kremlin critics.
Facebook Messenger Is Launching a Split Payments Feature for Users to Quickly Share Expenses
Meta has announced the arrival of a new Split Payments feature in Facebook Messenger. This feature, as the name suggests, will let you calculate and split expenses with others right from Facebook Messenger. This feature essentially looks to bring an easier method to share the cost of bills and expenses — for example, splitting a dinner bill with friends. Using this new Split Payment feature, Facebook Messenger users will be able to split bills evenly or modify the contribution for each individual, including their own.
The company took to its blog post to announce the new Split Payment feature in Facebook Messenger. 9to5Mac reports that this new bill splitting feature is still in beta and will be exclusive to US users at first. The rollout will begin early next week. As mentioned, it will help users share the cost of bills, expenses, and payments. This feature is especially useful for those who share an apartment and need to split the monthly rent and other expenses with their mates. It could also come handy at a group dinner with many people.
With Split Payments, users can add the number of people the expense needs to be divided with and, by default, the amount entered will be divided in equal parts. A user can also modify each person’s contribution including their own. To use Split Payments, click the Get Started button in a group chat or the Payments Hub in Messenger. Users can modify the contribution in the Split Payments option and send a notification to all the users who need to make payments. After entering a personalised message and confirming your Facebook Pay details, the request will be sent and viewable in the group chat thread.
Once someone has made the payment, you can mark their transaction as ‘completed’. The Split Payment feature will automatically take into account your share as well and calculate the amount owed accordingly.
