It's not science fiction. Scientists think 'space bubbles' could possibly save the planet.

This could be an actual real-life solution to Earth's climate change issue.

Scientists think space bubbles could save the planet.

Not everyone is into science or even cares how it works. But sometimes science is too cool to ignore. The scientists at Massachusetts Institute of Technology (MIT) are revisiting an old hypothesis from the late 1980s by astronomer Roger Angel on creating bubbles in space to make an umbrella of sorts to shade Earth. Yeah, they're suggesting space bubbles. Following advances in technology over the last 30 years, they now think they've figured out how to do it.


This news is not only incredible, it feels like it's straight out of a sci-fi movie. It may sound outrageous, but it could be an actual real-life solution to Earth's climate change issue. Climate change, according to the United Nations (UN), involves "long term shifts in temperature and weather patterns," which, since the 1800s, is primarily driven by human activities such as the burning of fossil fuels. Coal, oil and gas all produce heat-trapping gasses that are slowly warming Earth and causing increased carbon dioxide, the warming of oceans and polar ice melt, all of which endanger animals and cause sea levels to rise.

Just lately, it feels like we are melting when we spend more than a few minutes outside, but not everything is doom and gloom. Scientists are working to find a solution to the fiery Earth situation while the effects of newer renewable energy sources are being realized. And that's where space bubbles come in. The MIT scientists have been able to create a high-tech thin film in the form of a bubble in space-like conditions, which means this should be able to be recreated in space.

These scientists have asked for a "feasibility study" to see if space bubbles actually work, recommending the creation of a bubbly mass in space the size of Brazil. And no, it doesn't involve scientists blowing bubbles with a giant bubble wand—that would be pretty comical.

Example of space bubbles in action.

The high-tech bubbles if able to be hurled into space to save the planet could reflect wavelengths from solar radiation of different varieties. But there's this pesky thing called gravity. The bubbles would need to be far enough away from Earth that they don't get pulled down but far enough from the sun that they don't burn up. For the moment, researchers are just putting the idea out into the world with the hope that it can be built on in the future. Outside of the preliminary experiments that have shown that space bubbles are possible, more work has to be done to make them a reality.

In the meantime, we can enjoy the image in our heads of an umbrella made of space bubbles shading Earth. Envisioning astronauts popping them with a video game like laser gun is fun too. All eyes are on MIT as they figure out if we get to have space bubbles for Earth's birthday party in the next few years. In the meantime, we nonscientist humans should probably keep doing our part to slow climate change.

Some people say that while change is inevitable, progress is a choice. In other words, it’s a purposeful act—like when American media mogul and philanthropist Ted Turner established the United Nations Foundation 25 years ago.

Soul Asylum's "Runaway Train" actually saved 21 missing children.

Anyone who was a teen in the '90s will remember the grunge era. Nirvana, Pearl Jam and Soundgarden were topping the charts with their gravely metaphorical lyrics, but they weren't alone. Soul Asylum burst onto the scene with their solemn anthem "Runaway Train" complete with a video that showcased missing kids.

The video gave missing and exploited children a much bigger platform to be recognized on, because before the video was showcased on MTV, milk cartons were the common method to distribute these photos. In theory, milk cartons seem like a pretty effective way to highlight missing children, but in reality, eventually people would become blind to the photos.

The music video for "Runaway Train" was played all around the world and to the target audience that would most likely recognize the faces. It should come as no surprise, then, that the video helped to bring home 21 missing children. What is surprising, is that the band had to push to keep the pictures of the missing kids in the music video because people didn't think it was working.

Innovation is awesome, right? I mean, it gave us the internet!

However, there is always a price to pay for modernization, and in this case, it’s in the form of digital eye strain, a group of vision problems that can pop up after as little as two hours of looking at a screen. Some of the symptoms are tired and/or dry eyes, headaches, blurred vision, and neck and shoulder pain1. Ouch!

Palm Beach Post/YouTubeThey say a crisis brings out the best and the worst in people. It also reveals the best and the worst in our leaders.

A city commission meeting in Lake Worth Beach, Florida has gone viral after Commissioner Omari Hardy took his fellow city officials to task for their seeming indifference to their constituents during the coronavirus crisis.

Hardy confronted Mayor Pam Triolo and City Manager Michael Bornstein, who he said refused to call an emergency meeting last week, per Hardy's repeated requests, to discuss issues coming about from the coronavirus crisis. And he let his frustrations show.

"You're calling me disrespectful because I've interrupted people, but this gentleman has turned off people's lights in the middle of a global health pandemic," Hardy said, referring to Bornstein.

A newly single mom gets inspiring life advice from an internet grandma.

Becoming a single mom isn't easy, especially if it's unexpected and you feel wholly unprepared. Recently, a newly single mom posted a tearful plea on TikTok asking for advice on how to navigate her new life. But she wasn't without advice long, "TikTok Bubbie" stitched the video and responded explaining how she survived as an unexpectedly single mom in 1989.

The video was sweet and full of inspiration for single parents starting their journey. In the beginning of the video she explained that her ex-husband left her when her son was 4 years old and took all the money out of the bank account. Being suddenly single caused her to have to give up her acting career.

The internet Bubbie went on to tell the young mom, "I got furniture from the Salvation Army. That's right, I got secondhand furniture. Secondhand clothes for me, my son never. He always was first in my book and still is to this day." TikTok Bubbie wasn't done, she made a second video to expand on her advice.
