Art project or UFO? Scientists torn over 'mysterious sphere' found in Colombia

A weird, perfectly smooth metal ball found in Colombia has everyone scratching their heads—some think it might be alien tech, while others guess it’s just avant-garde art. Scientists are poking at it to figure out what it really is, but for now, the mystery’s wide open.

Editor’s Note: Whether it’s a UFO relic or someone’s idea of modern art, this story taps into our love of the unexplained. It’s a fun reminder that the world still holds surprises—and that sometimes, even experts don’t have all the answers right away.

Ever wondered what happens to light as it travels billions of years across the universe to reach us? Scientists have been puzzling over whether photons—those tiny particles of light—lose energy on their epic journeys. Turns out, the answer isn't as straightforward as you might think. While light doesn't "slow down" (it always zips along at that famous cosmic speed limit), its energy can shift due to the mind-bending effects of time dilation—a quirk of Einstein's relativity where time itself stretches or compresses depending on gravity and motion. So, that photon from a galaxy 25 million light-years away? It might arrive a little different than when it started, thanks to the universe's weird and wonderful rules.

Editor’s Note: This isn't just a nerdy physics rabbit hole—it's key to understanding how we observe the universe. If light's energy changed unpredictably, our measurements of distant stars and galaxies could be way off. But by untangling how time dilation affects photons, scientists can fine-tune everything from the age of the cosmos to the behavior of black holes. Plus, it’s a cool reminder that even something as "simple" as light plays by some seriously strange rules out there in the void.

Dick Garwin was a brilliant physicist who played a crucial role in preventing nuclear catastrophe during the Cold War, but he kept a major secret for five decades—one that could reshape how we see his legacy and the hidden battles waged behind the scenes of history.

Editor’s Note: This isn’t just another historical footnote—it’s a reminder that even the most celebrated figures have untold stories. Garwin’s secret could change how we understand the delicate balance of power during the nuclear age, and it raises questions about what else might still be hidden in the shadows of history. If you care about the real, messy, human side of science and geopolitics, this one’s worth your time.

China and Russia just inked a deal to team up on building a power plant on the moon, aiming to finish by 2036. Meanwhile, NASA seems to be dialing back its own moon plans, which could leave the U.S. lagging in the new space race.

Editor’s Note: This isn’t just about lunar real estate—it’s a high-stakes power move in the global competition for space dominance. If China and Russia pull this off, they could control key energy and tech resources on the moon, leaving the U.S. scrambling to catch up. It’s a reminder that the next frontier isn’t just about exploration; it’s about who calls the shots up there.

If you're thinking about buying a Tesla Cybertruck, you might want to check the resale value first. According to a Business Insider reporter, these futuristic-looking trucks lose their value way faster than other electric vehicles—meaning owners could take a big financial hit if they decide to sell.

Editor’s Note: Depreciation isn't just a nerdy finance term—it hits real people in the wallet. For Cybertruck buyers, this could mean losing thousands more than expected if they ever want to trade up or sell. It also raises questions about Tesla's long-term pricing strategy and whether the hype around the Cybertruck matches its actual market staying power.
