Never Too Late To Learn

  The Hidden Universe: Understanding Dark Matter and Dark Energy When you look up at the night sky, the stars, planets, and galaxies may seem to represent the entire universe. But according to scientists, all the visible matter—everything we can see—makes up less than 5% of the universe. The rest? It’s invisible. Unseen. Mysterious. Scientists call it   dark matter   and   dark energy , and together, these two unknowns account for about 95% of the universe. Though invisible, their effects are everywhere—and they may hold the key to the universe’s past, present, and future. What Is Dark Matter? Let’s start with   dark matter , which makes up about 27% of the universe. It’s called "dark" because it does not emit, absorb, or reflect light. In other words, we can’t see it—not with telescopes, X-rays, or any kind of electromagnetic radiation. So how do we know it’s there? The idea began taking shape in the 1930s when Swiss astronomer   Fritz Zwicky   obser...

  Understanding Blockchain: The Technology Behind Trust Never Too Late to Learn For many, the term   blockchain   is tangled up with buzzwords like   Bitcoin ,   NFTs , or   cryptocurrency . But underneath all the headlines is a powerful technology that is quietly transforming how we share information, handle money, and build trust in the digital age. Whether you’re 25 or 85, it’s never too late to understand what blockchain is, how it works, and why it matters. What Is Blockchain? At its core, a   blockchain   is a   digital ledger —a record of transactions or information—that is   distributed   across many computers instead of being stored in one place. Each record or group of records is stored in a “block,” and each new block is linked to the one before it, forming a secure chain of data. This structure ensures that once information is entered, it’s   incredibly difficult to change   without everyone knowing. In simpler...

  The Large Hadron Collider: Unlocking the Secrets of the Universe Never Too Late to Learn In the quiet countryside near Geneva, on the border between Switzerland and France, lies one of the most extraordinary scientific instruments ever built by humankind—the   Large Hadron Collider (LHC) . It is a 17-mile ring buried deep underground, where scientists send subatomic particles hurtling at nearly the speed of light to uncover the building blocks of the universe. Though the language of particle physics can sound like science fiction, the goal is deeply human: to answer the most fundamental questions about existence. What Is the Large Hadron Collider? The Large Hadron Collider is the world’s most powerful   particle accelerator , designed and operated by   CERN —the European Organization for Nuclear Research. Completed in 2008, the LHC is essentially a giant, circular tunnel equipped with powerful magnets, detectors, and cutting-edge computing systems. It was built to ...
