Consider you have a look at a fantastic viewpoint. The solar appears on the snowy peaks of the faraway mountains, the river shakes throughout the hills. There’s something superb in seeing the contours of an impressive panorama.
Possibly it isn’t glaring while you have a look at the night time sky, however the Universe has its personal panorama nity galaxies, separated via nearly empty voids. We now have recognized such a lot for a very long time. However now one staff of cosmologists makes issues additional and means that the Universe possess no longer best the panorama, but additionally the meantime division. The theory is that the very glide of time varies from position to position.
To mention that this is going in opposition to the grain is a needlessness: we at all times idea that on a big scale time passes on the similar velocity all over the universe. However on this image – referred to as the cosmology of the transient panorama – there are massive sections of the universe, the place time is flying billions of years longer than we normally suppose.
This may occasionally sound unusual, however what encourages some physicists is an easy class of this concept. There’s no extraordinary physics, it naturally arises from the established principle. “This is part of the structure of general relativity,” says its inventor David Wiltshire at Kenterbury College in New Zealand. “That is merely no longer an element …
