The universe has a finite age — 13.8 billion years to be exact. So if it had a beginning, why is it so difficult to say for sure whether it will have an end?
Dark energy is probably a sea of constant energy in empty space itself, according to new research.
The term ‘Big Bang’ might make you think of a massive explosion. Put the thought out of your head. Rather than an explosion, it was the start of everything in the universe.
Thirty years ago the Hubble Space Telescope began snapping photos of distant stars, providing a time machine that has taken astronomers back to when the universe was less than a billion years old.
The rate of the universe’s expansion is in dispute. But a new kind of measurement offers hope.
Astronomers are voting to rename one of the laws of physics. The voting may have far-reaching effects leading to renaming of other laws and giving ‘forgotten’ scientists due credit.
From a mysterious energy of empty space to parallel universes, cosmology’s view of ‘nothing’ is anything but boring.
New research out this month has led to speculation that the acceleration of the expanding universe might not be real after all. So what’s really going on?
Dark energy is a completely unknown source making up 70% of the universe. Will any of the new projects designed to find out what it is succeed?
In about 10100 years, the universe will have passed away in a tragic ‘heat death’. But don’t despair, eventually random conscious brains may pop out in empty space to shake things up.
Our universe’s most exciting days are well behind us, with new research showing the universe is now slowly but surely dying.
Einstein’s theory of gravity says dark energy must be out there, accelerating the expansion of our universe. But what is it and how can we try to figure out more about it?
Research of a supernova in our galaxy will increase the precision of which we can measure distances outside of our own galaxy…
