Why Tesla Cybertrucks drop sharply in value over time compared to other EVs

Black holes are some of the most mysterious and extreme objects in the universe—cosmic vacuum cleaners with gravity so strong that not even light can escape. This article breaks down how they form (often from collapsing stars), what they’re like inside (a one-way ticket to spaghettification, apparently), and why scientists are obsessed with studying them.

Editor’s Note: Black holes aren’t just sci-fi fodder—they’re real, mind-bending phenomena that challenge our understanding of physics. Learning about them helps us grasp how the universe works, from galaxy formation to the very fabric of spacetime. Plus, who doesn’t love pondering the ultimate "what if?" scenario of falling into one?

If you're in the market for a night vision monocular—whether you're a budget-conscious buyer or want top-tier performance—this guide rounds up the best options available in 2025, comparing features, prices, and overall value to help you pick the right one.

Editor’s Note: Night vision tech keeps getting better, and whether you're a wildlife enthusiast, security professional, or just love nighttime adventures, having the right gear makes all the difference. This guide cuts through the noise to highlight the best picks, saving you time and hassle in your search.

This article from Popular Science shares seven handy Google Maps tricks to make your drives smoother when using Android Auto or Apple CarPlay. It covers everything from personalizing your car’s on-screen avatar to reporting police sightings—small tweaks that can improve your navigation experience.

Editor’s Note: Most of us rely on Google Maps for daily commutes or road trips, but few dig into its extra features. These tips help drivers get more out of the app, making it safer or just more fun to use. It’s a quick, practical read for anyone who spends time behind the wheel.

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.
