When Will The First Star Go Dark?

Ever since the first star in the Universe ignited some 13.7 billion years ago, the Universe has been flooded with light. When enough matter — mostly hydrogen and helium gas — gravitates together into a single, compact object, nuclear fusion will take place inside the core, giving rise to a true …

A new phase of matter, called a time crystal, has been created and observed for the first time. In a regular crystal, the atoms are arranged in a …

Milky Way's Supermassive Black Hole Ate Its Last Big Meal 6 Million Years Ago

Most galaxies in the observable universe contain a supermassive black hole at their center, one that is either active and surrounded by an accretion …

Physicists have created an “impossible” state of matter that could power quantum computers

The laws of physics are supposed to be symmetrical in time and space. That means a ball thrown at a certain speed and in a certain direction would always go the same distance, no matter when you throw or where on Earth you throw it (assuming no other factors, like weather, came into play).<p>There …
