What powers life? In most ecosystems, sunlight is absorbed and converted into usable forms of energy via photosynthesis. These usable forms of energy are carbon-based. A primary example of this ...

Scientists think that only about 5% of the stuff that makes up the universe is known to us. Yes, you are reading that right. Cosmological models show that invisible energy and matter must make up a ...

Dark matter acts like gravity, holding the universe together. Dark energy acts like anti-gravity, speeding up the universe's expansion. Dark energy makes up most of the universe (68%), while dark ...

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the bending of space and time. Quantum mechanics governs the world of particles ...

For decades, astronomers have believed that dark matter and dark energy make up most of the universe. However, a new study suggests they might not exist at all. Instead, what we perceive as dark ...

The Standard Model of particle physics is currently our best understanding of how the universe works – but it only describes about five percent of everything in it. The rest is made up of what we call ...

Two experiments on Earth are helping to shine light on the hidden characteristics of dark energy and dark matter — elusive phenomena that make up nearly 95 percent of the universe but remain hidden ...

Systems of motile interacting units (active matter) exhibit fascinating emergent phenomena such as self-organization and directed motion at large scales. Familiar examples are flocks of birds, schools ...

"The new model can account for both structure formation and stability, and the key observational properties of the expansion of the universe at large." A new model of the cosmos does away with the ...

To learn about what characteristics define an organism. Life is ubiquitous on Earth and appears in a diversity of forms. But what characteristics do organisms have? What makes them alive? This ...

A recent study by Rajendra Gupta, published in "Galaxies," proposes that cosmic phenomena conventionally ascribed to dark matter and dark energy can be explained by the temporal weakening of ...
