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

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

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

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

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

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 ...

Atomic clocks are already precise enough to measure tiny effects of relativity, such as time dilation; for example, if you ...

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 ...

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 ...
