The universe could, in fact, be a giant doughnut, despite all of the evidence suggesting it's as flat as a pancake, new research suggests. All observations so far suggest the universe is flat. In ...

What if the universe remembers? A bold new framework proposes that spacetime acts as a quantum memory. For over a hundred ...

In a hypertorus model of the Universe, motion in a straight line will return you to your original location, even in an uncurved (flat) spacetime. The Universe could also be closed and positively ...

A new model suggests that the universe did not undergo a Big Bang followed by inflation, as the prevailing model suggests, but a cycle of "bounces". Though so very far from anything approaching ...

The shape of the universe is one of the most important questions in cosmology, with far-reaching implications, up to and including the ultimate fate of the cosmos. For decades, we've been measuring ...

Bayesian model averaging is a procedure to obtain parameter constraints that account for the uncertainty about the correct cosmological model. We use recent cosmological observations and Bayesian ...

I've long been fascinated by the fundamental mystery of our universe's origin. In my work, I explore an alternative to the ...

NEXT time you fancy doing something really frustrating, try balancing a pencil on its sharpened tip. Your efforts will succeed for a second at most. Yet the universe has been succeeding at a similar ...

So while the measurement is consistent with a flat universe, it is possible that the universe is closed and finite. However, the constraints are tight and if the universe is finite it must be very, ...
