Growing universe. Creating dimensions…
An international team of physicists has developed an out-of-the-box theory which proposes that shortly after it popped into existence 13.8 billion years ago the universe was filled with knots formed from flexible strands of energy called flux tubes that link elementary particles together. The idea provides a neat explanation for why we inhabit a three-dimensional…

Giant atoms. The same as small atoms…
Scientists have proposed a new theory that combines some of the most mysterious phenomena in the Universe – black holes, gravitational waves, and axions – to solve one of the most confounding problems in modern physics. And it’s got experts in the field very excited. The theory, which imagines a Universe filled with colossal ‘gravitational…

Blips of light. Cosmos full of nothing…
Observations of the dense remnant of an exploded star have provided the first sign of a quantum effect on light passing through empty space. Light from the stellar remnant, a neutron star located about 400 light-years away, is polarized, meaning that its electromagnetic waves are oriented preferentially in a particular direction like light that reflects…

Ghost images. Glows. At the corners of the universe…
A team of physicists at The Australian National University (ANU) has used a technique known as ‘ghost imaging’ to create an image of an object from atoms that never interact with it. Lead researcher Associate Professor Andrew Truscott from the ANU Research School of Physics and Engineering (RSPE) said the experiment relied on correlated pairs…

Supersymmetry. True? False? Does it matter?
A beautiful but unproved theory of particle physics is withering in the harsh light of data. For decades, many particle physicists have devoted themselves to the beloved theory, known as supersymmetry. But it’s beginning to seem that the zoo of new particles that the theory predicts – the heavier cousins of known particles – may…
