Traditionally, astrophysicists have stated that infant galaxies primarily took shape in the recognizable spherical and webbed disc patterns we see today. However, the outcomes of a new study have suggested otherwise.
According to an analysis of new images from the James Webb Space Telescope, baby galaxies were neither eggs nor discs. They were bananas. That is the tentative conclusion of a team of astronomers who reexamined images of some 4,000 newborn galaxies observed by Webb at the dawn of time.
Images from the Webb telescope suggest that newborn galaxies look weirder than expected. Exactly how screwy was physics at the dawn of time?
Astronomers have long contemplated the possibility that there may be forms of matter in the universe that are imperceptible, either because they are too far away, too dim or intrinsically invisible. Lord Kelvin was perhaps the first, in 1904, to attempt a dynamical estimate of the amount of dark matter in the universe. His argument […]
There simply isn't enough normal matter to account for the amount of gravitational force needed to hold the universe together, meaning dark matter must be prevalent.
