Gravitational Waves Were Used To Look Inside Neutron Stars

Last October, scientists witnessed the first neutron star collision thanks to gravitational wave observations and the subsequent use of regular telescopes. Those observations were the first step towards a...

The Very Hungry Supermassive Black Hole

0
We all get the munchies, but when you're a supermassive black hole (SMBH) your hunger might have dire consequences. And just like that an SMBH has outgrown its galaxy and jumped to the top of the heavyweight objects in the universe. About 12 billion light years from us, there is a galaxy called CID-947. It has a mass similar to our own Milky Way (about 1000 billion times the mass of the Sun) and it was only remarkable because it had an active galactic nucleus (AGN, i.e. an accreting SMBH).

Kepler has discovered the most Earth-like planet yet

The NASA's Kepler Space Telescope team have discovered the first Earth-size planet orbiting a star in the "habitable zone". The habitable zone, also known as the "Goldilock zone", is the...

Why the discovery of gravitational waves is so important

The Big Bang is not going anywhere.

0
On the 4th of February a paper was published detailing a Universe that didn’t need a Big Bang. While it is very interesting (you can read it here) I find myself once again at odds with how theoretical papers are formulated. The paper details a mathematical robust way to solve many cosmological conundrums. The flatness problem (discussed in this vlog), the value of dark energy and the nature of dark matter.
