The true “informational age” of the cosmos may be 62 billion years, not just the 13.8 billion years of our current expansion.

Modern science emerged precisely to deal with the way everything can be manipulated – and scepticism over ‘facts’ goes all the way back to Socrates.
Quantum information theory is the field behind quantum computing, but experts in this field are also applying their way of thinking to some big questions in quantum physics.
Observations during historical solar eclipses confirmed Einstein’s theory of gravity, and led to the predictions of black holes.
The nature of dark energy remains one of the biggest puzzles in cosmology.
Your experience of time is relative because it depends on motion – more specifically, your speed and acceleration.
Albert Einstein might have the answer.
There’s a special type of particle called a ‘tachyon’ which would have to travel faster than the speed of light. But here’s the hitch – we can’t prove tachyons even exist.
A new twist on an old experiment reveals several common-sense ideas about reality can’t all be true.
Albert Einstein may have been the ultimate example of a visionary genius, but that did not stop him from twice losing his way due to beliefs that were perhaps not so scientific.
It’s all about the strong gravitational field of the black hole.
Is dark energy just an illusion, as is often suggested? To resolve the dilemma, interpreting the basic principles of general relativity in a complex Universe may need a rethink.
There remain many mysteries that are beyond science. Does that mean that a God truly exists? A scholar gives reasons for this possibility.
