A study provides crucial clues about how cosmic objects send accelerated particles through space. Jets coming from quasars and supernovae can send dangerous cosmic rays that hit Earth. For the first ...

Since Einstein, physicists have found that certain entities can reach superluminal (that means "faster-than-light") speeds and still follow the cosmic rules laid down by special relativity.

Recent research has unveiled a startling revelation: our solar system is moving at a velocity that is three times faster than previously anticipated. This discovery, announced on November 14, 2025, ...

In a new study, Dartmouth researchers rule out a controversial theory that the accelerating expansion of the universe is an illusion. While the findings don’t explain the cosmic speed-up, they ...

Fermilab: Scientists announced that the Dark Energy Survey soon expects to make a substantial leap forward in our understanding of why the universe is accelerating and the nature of dark energy.

A newly proposed cosmic speed limit may constrain how fast anything in the universe can grow. Its existence follows from Alan Turing’s pioneering work on theoretical computer science, which opens the ...

James Miller-Jones receives funding from the Australian Research Council and the Western Australian State Government. How fast can a neutron star drive powerful jets into space? The answer, it turns ...

The supermassive black hole at the heart of our galaxy isn't just spinning — it's doing so at almost maximum speed, dragging anything near it along for the ride. Physicists calculated the rotational ...
