The far distant fates of the Universe offer a number of possibilities, but if dark energy is truly a constant, as the data indicates, it will continue to follow the red curve, leading to the long-term ...

New supercomputer simulations hint that dark energy might be dynamic, not constant, subtly reshaping the Universe’s structure. The findings align with recent DESI observations, offering the strongest ...

An international collaboration of scientists has created the largest 3D map of our universe to date based on the first results from the Dark Energy Spectroscopic Instrument (DESI). It’s an impressive ...

The expansion of the universe could be a mirage, a potentially controversial new study suggests. This rethinking of the cosmos also suggests solutions for the puzzles of dark energy and dark matter, ...

Long after the last star in the Universe has burned out, the final black hole will decay away. Even after that happens, however, and even after waiting arbitrarily long amounts of time for the ...

For over a century, scientists have wondered what is counteracting the force of gravity in the universe. The universe is vast, almost beyond comprehension. It has an estimated diameter of 93 billion ...

For decades, astronomers have relied on Einstein’s theory of relativity to explain the expansion of the universe, assuming that dark energy—a mysterious force making up 70% of the cosmos—remains ...

“Dark energy” is a term scientists use to refer to whatever is causing the universe to expand faster over time. We don’t know exactly what dark energy is—no one has ever directly seen or measured ...

An artist’s impression of the cosmic web. Shown as a vast cobweb-like structure of mostly purple and some orange filaments on a black background, the web is the soap-sud structure of the universe ...
