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.
The oldest exoplanetary star-system has been discovered by Kepler. The system orbiting Kepler 444 was older than the Earth today when the Sun first shone light.
