The most amazing thing about light is that it takes time to travel through space. Because of that one simple fact, when we look up at the Universe we see not a snapshot but a history. The photons we capture with our telescopes tell us about their journey. This is particularly true when gravity comes into play, since gravity bends and distorts the path of light. In a recent study, a team shows us how we might use this fact to better study black holes. Near a black hole, our intuition about the behavior of light breaks down. For example, if we imagine a flash of light in empty space, we understand that the light from that flash expands outward in all directions, like the ripples on a pond. If we observe that flash from far away, we know the light has traveled in a straight line to reach us. This is not true near a black hole. The gravity of a black hole is so intense that light never travels in a straight line. If there is a flash near a black hole, some of the light will travel directly to us, but some of the light will travel away from us, only to be gravitationally swept around the backside of the black hole to head in our direction. Some light will make a full loop around the black hole before reaching is. Or two loops, or three. With each path, the light travels a different distance to reach us, and therefore reaches us at a different time. Rather than observing a single flash, we wound see echoes of the flash for each journey. In principle, since each echo is from a different path, the timing of these echoes would allow us to map the region around a black hole more clearly. The echoes would tell us not just the black hole’s mass and rotation; they would also allow us to test the limits of general relativity. The only problem is that with current observations, the echoes wash together in the data. We can’t distinguish different echoes. This is where this new study comes in. The team propose observing a black hole with two telescopes, one on Earth and one in space. Each telescope would have a slightly different view of the black hole. Through long baseline interferometry the two sets of data could be correlated to distinguish the echoes. In their work the team ran tens of thousands of simulations of light echoes from a supermassive black hole similar to the one in the M87 galaxy. They demonstrated that interferometry could be used to find correlated light echoes. It would be a challenge to build such an interferometer, but it would be well within our engineering capabilities. Perhaps in the future, we will be able to observe echoes of light to explore black holes and some of the deepest mysteries of gravity.

All five answers to the questions below have something in common. Can you figure it out?

Just an hour after a critical heart surgery, Louis Hood lifted his voice to Elton John’s “I’m Still Standing,” a fitting anthem for the resilient young boy born with a rare heart condition. The moving performance brought tears to the eyes of his mother, Jodie Hood, who shared that this small act was a reminder of Louis' strength and spirit. Louis, who lives in Redruth, Cornwall, was born with a condition that left him with half a functioning heart. Since birth, he has undergone three open-heart surgeries, starting when he was just nine days old. As he approached his fourth birthday, Louis needed another operation to insert a stent into his pulmonary artery, a procedure that brought the family to Bristol Children’s Hospital. "We call him our mountain-mover as he loves to defy the odds." — Jodie Hood Jodie, overwhelmed with emotion, explained the impact of Louis' spontaneous song. “He started singing from the movie Sing on his iPad—it was incredibly moving,” she said. A dream trip to Disneyland Paris With Louis’ condition demanding continuous medical care, his family lives with the daily uncertainty of what the future holds. But amid the challenges, they are hoping to create joyful memories. Louis dreams of a magical trip to Disneyland Paris, and with his love for all things Disney, his family is dedicated to making this happen. To fund this dream, Louis’ grandmother, Sharon Van Beusekom, started a JustGiving fundraiser to help cover the expenses for Louis and his family. The goal of £8,000 would not only pay for the trip but also account for the costs associated with Louis' special medical needs during travel. "Louis has one big dream: to visit Disneyland Paris... memories that will bring comfort and happiness no matter what the future holds." — Sharon Van Beusekom “Whether we have a few months or a few precious years, we’re living with the constant fear of losing him,” Sharon shared. “Louis is such an amazing little boy with a zest for life and a smile that lights up every room. He deserves this chance to make happy memories with his family.” A legacy of resilience and joy Louis Hood and his contagious smile.Sharon Van Beusekom via Just Giving The Hood family has been through incredible challenges, especially with the recent loss of a young friend, Faith, who had the same condition as Louis but sadly passed away at just 22 months old. This heartbreaking reminder of the fragility of life has further motivated them to fulfill Louis' wish, despite the challenges ahead. Support has already begun pouring in, with friends, family, and well-wishers rallying around Louis. The family’s story has gained traction online as well, with more than 2,000 Reddit users expressing their admiration and support. One commenter, u/Hayes4prez, noted, "Pretty tough kid, I hope he’s up playing again soon." Another, u/masteremrald, commented, "Four open heart surgeries at such a young age is crazy. Amazing to see how he is able to stay positive after all that!" "Makes a grown man tear up ?" — @AbleEnd3877 Jodie, Louis’ mother, has even participated in sponsored runs to help boost the fund. The family is hoping for a little more support to reach their target, and any surplus will be donated to Heart Heroes, a charity supporting families with children facing serious heart conditions. Jodie expressed gratitude for everyone’s generosity, saying, “Louis has overcome so much, and any help we can get to bring a little happiness his way means the world to us. This is our way of giving him something to look forward to, and we are so grateful to everyone who has helped make this possible.” "This is our way of giving him something to look forward to, and we are so grateful." — Jodie Hood For anyone who would like to contribute, donations can be made on the JustGiving page dedicated to Louis’ dream trip. With this support, Louis’ family hopes to bring joy and peace to their brave little boy, no matter what the future holds.

It’s hard to think of a more iconic sunglass design than the Ray-Ban Wayfarer. The shades are a staple of the American wardrobe and have a special place in cinema history, appearing in unforgettable films such as “The Blues Brothers,” “The Wolf of Wall Street” and “Risky Business.”The sunglasses' classic design has made them a hit with the public, but their success on the silver screen is primarily due to some savvy business moves by Ray-Bans' parent company, Bausch and Lomb.Toni’s Film Club, a channel dedicated to film history, shared the story of how Ray-Bans became so popular in films on YouTube. - YouTube www.youtube.com When were Ray-Ban Wayfarer sunglasses invented?Ray-Ban Wayfarer sunglasses were initially released in 1952. Their cutting-edge design is attributed to injection-molded plastic, whereas previously, sunglasses were made from wireframes. The sunglasses became a hit after James Dean wore them in 1955’s “Rebel Without a Cause” and became a staple amongst the counter-culture.In the 1960s, Elvis Presley, The Beatles, and Bob Dylan wore Wayfarers, cementing their place in the hipster wardrobe for years to come. However, in the ‘70s, the Wayfarers began to lose their way with the public at-large.“By the 1970s [Wayfarers] had fallen out of style in favor of the more subtle and elegant frames and the sales had decreased so much that Ray-Ban was planning to discontinue the model. But little did they know in the summer of 1980, things were about to change,” Toni says.In 1980, Dan Aykroyd and John Belushi starred in the megahit comedy “The Blues Brothers” and wore black Wayfarers with their two-tone black-and-white outfits. The film would be a smash for the “Saturday Night Live” alumnus, and Wayfarers were back in style overnight.Interestingly, the Blues Brothers were the antithesis of early ‘80s fashion. “Their sleek black suit and tie was a nod to earlier African American menswear and blues culture,” Bianca writes at Costume Rhapsody. “Artists like BB King, John Lee Hooker wore fedoras and suits. Many Blues artists wore impeccably tailored suits and fedoras to every gig. It was elegant Black culture, the blues, counterculture, and Chicago history.”Why are Ray-Ban sunglasses so popular in movies?After the success of “The Blues Brothers” in 1982, Ray-Ban signed a $50,000 deal with a company specializing in product placement. Over the following years, their sunglasses would be featured in over 60 movies and TV shows. Before “The Blues Brothers,” Ray-Ban sold 20,000 pairs of Wayfarers a year; by the time Tom Cruise donned the shades and danced in his underwear in 1983’s “Risky Business,” sales were up to 360,000 yearly.In 1984, Don Johnson wore them with his white jacket, sportcoat and pink T-shirt on “Miami Vice” and sales spiked to 720,000 a year. After Bruce Willis wore them in “Moonlighting” and they were featured in “The Breakfast Club” (1985), sales were up to 1.5 million a year.“[The Wayfarer] became a pop culture phenomenon. It was referenced in songs, books and media. It was worn by so many iconic people that it turned into a symbol of being cool,” Toni says in the video. “I mean, even the cool emoji wears them. And nowadays, more than half a century later, it can still be seen in a long list of film and TV.”

"The Carol Burnett Show" ran from 1967 to 1978 and has been touted as one of the best television series of all time. The cast and guest stars of the show included comedic greats such as Tim Conway, Betty White, Steve Martin, Vicki Lawrence, Dick Van Dyke, Lyle Waggoner, Harvey Korman and others who went on to have long, successful comedy careers. One firm rule Carol Burnett had on her show was that the actors stay in character. She felt it was especially important not to break character during the "Family" scenes, in which the characters Ed and Eunice Higgins (a married couple) and Mama (Eunice's mother) would play host to various colorful characters in their home. "I never wanted to stop and do a retake, because I like our show to be ‘live,’" she wrote in her memoir, as reported by Showbiz Cheat Sheet. "So when the ‘Family’ sketches came along, I was adamant that we never break up in those scenes, because Eunice, Ed, and Mama were, in an odd way, sacred to me. They were real people in real situations, some of which were as sad and pitiful as they were funny, and I didn’t want any of us to break the fourth wall and be out of character.”It was a noble goal, and one that went right out the window—with Burnett leading the way—in a "Family" sketch during the show's final season that ended with the entire cast rolling with laughter. In the scene, Eunice, Mama, Dan (an old friend of Ed's) and Mickey (Ed's employee at the hardware store) are playing "Password" and the word they're trying to get their partners to guess is "ridiculous." Eunice (played by Carol Burnett) gives Mickey (played by Tim Conway) the clue word "laughable," and after pondering for a bit, he says "elephant."Eunice scolds him for his bizarre answer, then Conway launches into a wild ad-libbed story about a circus elephant that goes on and on and on.Burnett is the first one to lose it. The cast barely keeps it together through the sketch.But that was just one take. Between takes, the director gave the actors a note: The elephant story would be different in the next filming—and good luck.The next elephant story was even wilder than the first, and Burnett and Dick Van Dyke couldn't stop themselves from laughing. Conway himself breaks a couple of times, and even Vicki Lawrence (playing Mama), who famously never broke character, had to hide her face for a moment. Then, just when they finally got themselves composed and Burnett was able to deliver her line, "Go on, Mama," Lawrence delivered the most perfectly timed a-bomb and the whole cast exploded:So delightful. And for an added bonus, watch Vicki Lawrence tell the story about how that scene came about:See the full interview at https://emmytvlegends.org/interviews/people/vicki-l...This article originally appeared on 9.14.22

It's amazing to consider just how quickly the world has changed over the past 11 months. If you were to have told someone in February 2020 that the entire country would be on some form of lockdown, nearly everyone would be wearing a mask, and half a million people were going to die due to a virus, no one would have believed you.Yet, here we are.PPE masks were the last thing on Leah Holland of Georgetown, Kentucky's mind on March 4, 2020, when she got a tattoo inspired by the words of a close friend."We were just talking about things we admire about each other and he said, 'You courageously and radically refuse to wear a mask,' like meaning that I'm undeniably myself. I thought that was a really poetic way of saying that," Holland told Fox 13.So, she had "courageously & radically refuse to wear a mask" tattooed on her left forearm. It's a beautiful sentiment about Leah's dedication to being her true self. It's also a reminder for Leah to remain true to herself throughout her life.However, the tattoo would come to have a very different meaning just two days later when the first case of COVID-19 was reported in Kentucky."It basically looked like I'm totally, you know, anti-mask or whatever, which is not the case," said Holland.Now, she was embarrassed to be seen with the tattoo for fear she'd be associated with the anti-maskers who either deny the existence of the virus or refuse to wear a mask to protect others. Either way, it's a bad look.So Leah started wearing long-sleeve shirts and cardigan sweaters whenever in public to cover up the tattoo.On Monday, TikTok users asked each other to share their "dumbest tattoo" and she was pretty sure she had the winner. @wakaflockafloccar #stitch with @hannanicbic I could NOT have had worse timing. #fyp #foryoupage #tattoo #worsttattoo #winner ♬ original sound - wakaflockafloccare In her video, she talks about how her tattoo was about "not pretending to be something you're not," but then revealed it to show how — after a historical twist — it made her out to be someone she isn't."I just kind of wanted people to laugh with me because I think it's funny now, too," said Holland.Plenty of people on TikTok laughed along with her with one user suggesting she update the tattoo with the phrase: "Hindsight is 2020.""I was dying laughing. I'm like, I'm glad there are people that find this as funny as I think it is," said Holland."It will be a funny story to tell years from now," she said. "I don't think it will ever not be a funny story."Unfortunately, even when the pandemic is over, Leah will still probably have to explain her tattoo. Because most won't soon forget the COVID-19 era in America and there's no doubt many will still feel passionate about those who refused to wear a mask.This article originally appeared on 02.24.21

Heidi Johnson's son was 13, deeply in adolescence, and in that stage where he lashes out.He told her he shouldn't have to deal with her rules and should be independent.So she wrote a strict but loving "Mom's not a fool" letter.She wrote on Facebook how her son reacted to the letter:"He came home, saw the note, crumpled it on the floor, and stormed out of the apartment. I have always encouraged him to take a walk when he is upset so that he can collect his thoughts so when we try to talk, we are able to talk, and not just yell at each other. I do the same thing — sometimes, I just need to walk away and collect myself. I am not above admitting that. He was still livid when he got home. He decided to stage a 'sit in' in my room, where he did laugh at me and repeat, 'Really? What are you going to do? You can't take my stuff,' etc. He was asked to leave my room, and when he could be respectful, and I was more calm, we would discuss it further. He went to his room, and after about an hour, he had removed some electronics and items I missed that he felt he should have to earn back for his behavior. He apologized, and asked what could he do to make things better and start earning items back. He earned his comforter and some clothes right back. I did leave him some clothes to begin with, just not the ones he would want to wear every day. He also had some pillows and sheets, just not his favorite ones.”She decided to post it on Facebook, the way one does to friends for a laugh and connection. She neglected to make it "private," and soon comments and shares proliferated, including admonishments from strangers who thought she was a bad parent.Now she had to deal with a bigger teenager: the internet and its commentariat. But Johnson remained level-headed and wrote another Facebook post, clarifying."It's out there; and I am not ashamed of what I wrote... I am not going to put my 13-year-old on the street if he can't pay his half of the rent. I am not wanting him to pay anything. I want him to take pride in his home, his space, and appreciate the gifts and blessings we have.” She explains that he is more grateful because of it, and also that he has slowly earned back things and dealt with sacrificing others. Then she lists her very organized and succinct rules of the house:1 – Do your best in school! I don't expect a perfect 100%, but I do expect that you do your best and ask for help when you don't understand something.2 – Homework and jobs need to be done before you can have screen time.3 – Jobs are emptying the trash, unloading the dishwasher, throwing away trash you make in the kitchen, rinsing dirty dishes, making your bed daily, pick up bedroom nightly, and cleaning your bathroom once a week.4 – You must complete two chores a day. Each day of the week with the exception of Sunday has a room that we work on cleaning. He has to pick two chores for that room. For example, if it is the living room he can choose two of the following options: dust, vacuum, polish furniture, clean windows, mop the floor.5 – Be respectful and kind with your words — no back talking, no cussing at me.6 – Keep good hygiene.7 – Make eye contact when being spoken to, and be an active listener.8 – Use proper manners."You know what.. this hasn't hurt our relationship. He and I still talk as openly as ever. He has apologized multiple times... And… he is trying harder." Her son is earning things back little by little, and appreciating it more than he did before."This came down to a 13-year-old telling his mother she had no right to enforce certain rules, and had no place to 'control' him. I made the point to show what life would look like if I was not his 'parent,' but rather a 'roommate.' It was a lesson about gratitude and respect from the very beginning. Sometimes, you have to lose it all to realize how well you really had it."This article originally appeared on 8.16.21
