Scientists have detected cosmic waves that sound like chirping birds in an unexpected place NEW YORK -- Scientists have detected cosmic waves that sound like birds chirping in an unexpected place.

As the star spins, these beams sweep past Earth and produce periodic pulses of radio waves, much like a cosmic lighthouse. This behaviour has earned them the name “pulsars”. Pulsars typically ...

What is the structure of our physical reality? Physicists have long imagined space and time interweaving into “space-time”, the metaphorical fabric that underlies the cosmos. But there may be ...

However, Lane and his colleagues tested an alternative idea called the timescape model, which suggests that the apparent acceleration could be a byproduct of cosmic structures like voids — vast ...
