If every supervolcano erupted, billions of tons of ash and gas could flood the air, likely leading to volcanic winter, acid rain, and global famine.
Clouds cover about 70% of the planet at any moment. But what if - poof - they all disappeared? Long story short, we'd have huge problems on our hands.
Our first stop on our trip to the Sun will be the corona -the outermost layer of the sun, which is 1 million degrees Celsius. We’ll also pass through the chromosphere and photosphere, where we might get a glimpse of sunspots, solar prominences, and solar flares. The sun has no […]
If Santa really delivered presents on ChristmasEve, he’d need to fly over a thousand times faster than the world’s faster jet fighter to visit about 240 million homes. If every kid received one mid-sized LEGO set, the gifts would weigh a whopping 600,000 tons. Just like a spacecraft heats up […]
Disney unveiled new projects and new trailers at the Disney investors day, with “What If…?” getting its first-ever trailer. The animated Disney Plus anthology show is based on the comics series of the same name and will revolve around MCU events that happen differently in other realities. One idea will […]
“Why do we sleep?” has been a notoriously difficult question for scientists to answer, but, “What happens if we don’t?” is actually pretty simple – nothing good. Not getting enough sleep can make you hallucinate, mess with your thinking and memory, and even lead to organ failure. And it doesn’t […]
Your hands can have anywhere from 100,000 to a few million germs at any given time. Some of those germs live naturally on your skin to protect you, but a lot of them are picked up in the environment. If you stopped washing your hands, you become more likely to […]
In 2017, NASA’sCassini probe sent us our closest view of Saturn in space to date, diving right by its famous rings. If you wanted to take a closer look at the ringed planet, you would have to travel 1.2 billion kilometers, which would take about 8 years… but the long […]
Staying home forever might sound like a dream come true for introverts, but it can have serious consequences. The longer you’re inside, the more it can affect your physical and mental health. Not being exposed to sunlight can bring down your mood and, eventually, even soften your bones, among other […]
Surviving the apocalypse is the first step, but what’s next? Head to the grocery stores, hospitals, and pharmacies to stock up on supplies. Move out of the city and start a new life in the great outdoors. Then start re-building your life. Settle near fresh water, but not too close […]
A perfect balance of events occurred for this planet to support life. That delicate state continues to this day where small changes can have huge impacts on the world. So what would it look like if things drastically changed? What if the Earth spun sideways instead? Or what would happen […]
It’s a natural cycle: the Earth orbits the sun. But what if something catastrophic happened and we were knocked out of orbit? The sun’s gravity would quickly take hold of Earth and we’d go flying straight toward the sun. Turns out, you’d only have about one month to live, and […]
If all the ice on Earth melted overnight, the planet would be sent into chaos. There would be mass flooding from sea level rise, severe weather changes, deadly chemical release, and mass greenhouse gasses that will leak into the atmosphere. Scientists say we need to stop this planet from rising […]
VIDEO: It's a classic fable that dates back decades, but as we all (hopefully) know, the moon is not actually made of cheese. But what if it were?
