Physicists have introduced quadratic quantum gravity (QQG), a theoretical extension of Einstein’s general relativity, that could eliminate the Big Bang singularity. This model envisions the universe ...

Physicists have long suspected that there is a layer of physical reality beneath quantum theory and a new mathematical model ...

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

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

In quantum mechanics, particles do not behave like everyday objects. Instead of existing in one clearly defined state, they ...

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 ...

A new study suggests that certain 'quantum collapse models'—which posit that wavefunction collapse happens spontaneously—could be tied to gravity, introducing a tiny intrinsic uncertainty in time ...

For the first time, scientists have observed quantum entanglement in the momentum of massive particles. The result, decades ...

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 ...
