Physicists have proposed a modified version of Einstein’s general relativity, called quadratic quantum gravity (QQG), that could eliminate the Big Bang singularity and naturally produce cosmic ...

Only about 5% of the universe is composed of normal matter that we can directly observe, while the remaining 95% is widely ...

In quantum physics, objects can exist in multiple states at the same time—a phenomenon known as quantum superposition, where ...

Quantum collapse models hint at tiny time fluctuations. Credit: FQxI/Gabriel Fitzpatrick (2026) An FQxI cofunded study ...

Time already behaves strangely in modern physics. It can stretch, slow, and split depending on speed and gravity.

A key question in physics is whether gravity follows quantum rules, but testing this is difficult because gravitational ...

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at once, described by a mathematical object called a wavefunction. Yet daily life ...

The most precise clocks ever built can now detect gravity’s warping of time across a distance shorter than a pencil tip. That ...

We think of it as rigid, smooth, and unidirectional – the arrow of time flies straight and true, and all we can do is go ...

Large masses – such as a galaxy – curve space-time. Objects move along a geodesic. If we take into account that space-time itself has quantum properties, deviations arise (dashed line vs. solid line).

In April 2026, Infleqtion, Inc. filed a shelf registration for up to US$1.11 billion of common stock, while also reporting 2026 revenue guidance of US$40 million and continuing its role as NASA JPL’s ...
