The new theory contradicts earlier predictions that these ‘shortcuts’ would instantly collapse.

Wormholes, or portals between black holes, maybe stable after all, a wild new theory suggests.

The findings contradict earlier predictions that these hypothetical shortcuts through space-time would instantly collapse. 

The sea change comes because tiny differences in the mathematics of relativity, which is used to describe such wormholes,  end up dramatically changing our overall picture of how they behave.

On July 9th, 1968, eight white mice were placed into a strange box at the National Institute of Health in Bethesda, Maryland. Maybe “box” isn’t the right word for it; the space was more like a room, known as Universe 25, about the size of a small storage unit. The mice themselves were bright and healthy, hand-picked from the institute’s breeding stock. They were given the run of the place, which had everything they might need: food, water, climate control, hundreds of nesting boxes to choose from, and a lush floor of shredded paper and ground corn cob.

This is a far cry from a wild mouse’s life—no cats, no traps, no long winters. It’s even better than your average lab mouse’s, which is constantly interrupted by white-coated humans with scalpels or syringes. The residents of Universe 25 were mostly left alone, save for one man who would peer at them from above, and his team of similarly interested assistants. They must have thought they were the luckiest mice in the world. They couldn’t have known the truth: that within a few years, they and their descendants would all be dead.

Think your area has had more rain than usual? You’re probably right. 

Think your area has had less rain than usual? Again, you’re probably right. 

For our climate change investigation out this week, called Downpour, USA TODAY reporters used 126 years of monthly data from the National Oceanic and Atmospheric Administration to analyze average annual precipitation at 344 climate divisions. They used daily precipitation data from weather stations to measure the change in frequency of extreme rain events across the U.S. from 1951-2020.

“We were hearing a lot about extreme rainfall, stories of flooding, people with sewer backups, people flooded out of their homes, and we wanted to know, is this happening everywhere?” said Dinah Pulver, one of the project’s lead reporters. “How many people, how many places, are contending with this kind of rainfall?

We found more than half of the nation’s 344 climate divisions had their wettest periods on record since 2018. We calculated the same rolling averages for states. 

“East of the Rockies, more rain is falling, and it’s coming in more intense bursts,” our report finds. “In the West, people are waiting longer to see any rain at all.

“Taken together, the reporting reveals a stunning shift in the way precipitation falls in America.”

Leonard’s Comet, expected to be the brightest comet this year, should be the next sky-sighting on your bucket list. The moon has been keeping this comet washed out as it is much brighter than the space rock. There have been conflicting reports on social media over the past few days that the comet might have even disintegrated. Fear not: Leonard’s Comet is still there and was bright enough to be seen on cameras and through telescopes on Thursday, and it should remain bright enough to be seen over the next few weeks. When the solar system formed, not every piece of rock and ice made its way into a planet. These leftover pieces became comets, which now orbit the sun. The celestial rocks range from just a few miles to tens of miles wide. When one of the floating rocks gets close to the sun, it heats up enough that it spews gas and dust, leaving behind that familiar tail in the sky. 

What is Leonard’s Comet?

Astronomer Gregory J. Leonard discovered this comet in early 2021, later named for him, at the Mount Lemmon Observatory in the Santa Catalina Mountains, northeast of Tucson, Arizona. When Leonard spotted the comet, it was extremely dim, out near Jupiter, and was just starting to release it’s heated up gas and dust. Leonard’s comet has spent roughly 35,000 years getting closer to our sun and has finally made its way closer to Earth’s neck of the universe. It’s expected to be the brightest comet of the year.

About 5,300 years ago, an ancient civilization emerged in the east of China, building a brilliant city the likes of which had perhaps never been seen before in all of Asia – nor possibly even the whole world.

The surviving traces of the Liangzhu culture, which rose up along the banks of the Yangtze River Delta in China’s east, are a testament to what this unique Neolithic society was capable of in the final stretches of the Stone Age.

The archaeological ruins of Liangzhu City demonstrate numerous signs of social, cultural, and technological advancements for the period, especially in agriculture and aquaculture.

Sophisticated architectural features, meanwhile – including clever hydraulic engineering that enabled canals, dams, and water reservoirs – led to allusions of Liangzhu being a Neolithic “Venice of the East”.

None of these marvels would last, however.
