"The Bubble Universe" – A New Model of the Cosmos

Posted on December 28, 2018 As Peter Woit, theoretical mathematician of Columbia University, says, string theory is "not even wrong" because it is not falsifiable, the basic principle of all science theory. Now researchers at Uppsala University have developed another "new model" for the Universe based on string theory – one with the added bonus they suggest could solve the …

Huge collisions shake the cosmos

Whenever a new instrument was invented to study the sky, astronomers had to rethink their understanding of the cosmos. More recently, scientists have triggered a revolution in astronomy by finding out how gravitational waves can be observed using lasers and mirrors using a new technology. Black holes are the shells of massive stars whose gravity is so strong that not …

Galactic collisions bounce over eons to form our view of the cosmos

For centuries man has seen the cosmos as something stable and static. But we are increasingly learning that this is not the case. "We see that the universe is much more active, in contrast to the view of ancient astronomers that things were much more passive," says Eric Chaisson, astrophysicist at the Harvard-Smithsonian Center for Astrophysics. Take, for example, our …

How multimessenger astronomy creates clues to the cosmos

A Stronomer Had a Blockbuster Year In addition to finding a cosmic source of neutrinos, they have discovered the fusion of two city-sized neutron stars, each one of them more massive than the Sun. [196592002] The discoveries were interpreted as proof that a "new era of multisensory astronomy" has arrived. But what is multisensory astronomy? In our daily lives we …
