For nearly 100 years, physicists have tried to reconcile the physics of the smallest building blocks in the universe (quantum physics) with the physics of large galaxies (Einstein’s theory of general relativity). But they kept coming up against one requirement that was hard to swallow: Their theories only work if we live in a multiverse … Read more
The new video shared on YouTube is one of the most amazing things we’ve seen in planetary science. The video shows four points of light moving in partial concentric circles around a black disk at its centre. What you are actually looking at is a planetary system. The four points are exoplanets, with a black … Read more
CNN – A new study using machine learning reveals that the planet could pass critical warming thresholds sooner than previous models predicted, even with coordinated global climate action. The study estimates that the planet could reach 1.5°C of warming above pre-industrial levels in a decade, and finds a “significant potential” for global warming to exceed … Read more
