- A Dark Dimension Could Link Two of the Universe’s Great Unknowns
The article explores the possibility of a dark dimension connecting dark energy and dark matter, which together account for approximately 95% of the universe. Dark energy, making up about 70%, drives cosmic expansion, while dark matter, comprising 25%, helps maintain galaxy structure.
- 25 scientific laws explained simply for non-scientists
The article explains 25 scientific laws, including Newton's laws of motion and the second law of thermodynamics, in simple terms for non-scientists. It focuses on making complex universal rules accessible without using jargon.
- How the electromagnetic spectrum opened our eyes to the universe
The article discusses how the electromagnetic spectrum, first understood in part by Isaac Newton, continues to be a tool for astronomers to explore the cosmos. Astrophysicist Emma Chapman examines how these invisible waves might reveal new cosmic insights and potentially indicate we are not alone.
- First-ever direct image of the cosmic web reveals the Universe’s hidden highways
Astronomers have captured the sharpest image of a filament in the cosmic web, revealing a hidden structure connecting galaxies across the Universe. The image shows a glowing strand stretching 3 million light-years and linking two galaxies from nearly 12 billion years ago. This discovery provides new insight into how galaxies are fueled and formed.
- Scientists make stunning discovery that could change our understanding of the Universe
Scientists have made a discovery that could change our understanding of the Universe, finding that the Universe's fundamental constants sit within a narrow 'sweet spot' that allows liquids to flow properly inside living cells. This sweet spot is crucial for life as we know it, and tiny shifts in these constants could make life impossible. The discovery sheds new light on why life exists at all.

- What is quantum gravity? Scientists think it could explain the beginning of our universe
Scientists are exploring quantum gravity as a potential explanation for the beginning of the universe, particularly the events surrounding the Big Bang. The theory aims to reconcile general relativity with quantum mechanics to understand the singularity at the dawn of time.
- Brace for the 'Big Crunch': Scientists predict when the universe will end - and it's TRILLIONS of years sooner than we thought
Scientists predict the universe will end in a 'Big Crunch' scenario, which is now estimated to occur trillions of years earlier than previously thought. The revised timeline challenges earlier assumptions about the universe's lifespan and ultimate fate.
- Brace for the 'Big Crunch': Scientists predict when the universe will end - and it's TRILLIONS of years sooner than we thought
Scientists predict the universe will end in a 'Big Crunch' trillions of years earlier than previously estimated, challenging existing cosmological timelines. This revised timeline suggests a faster collapse of the universe compared to earlier models.
- NASA scientist says a "fifth force" may be hiding in our solar system
Scientists are investigating why the Universe behaves differently on massive scales compared to the solar system, with theories pointing to dark energy or a hidden 'fifth force'. Observations of distant galaxies suggest gravitational anomalies not seen locally, where Einstein's laws remain consistent.
- Isaac Asimov: The Last Question
The article discusses Isaac Asimov's short story 'The Last Question,' which explores the theme of entropy and the universe's inevitable end. It highlights the story's philosophical and scientific questions about life, death, and the role of artificial intelligence in confronting cosmic entropy.
