Planck Time is the shortest measurable moment in the Universe,just 5.39 × 10⁻⁴⁴ seconds. It’s a concept so extreme that it stretches the limits of physics and challenges our very understanding of time ...

Random twists of place: How quiet is quantum space-time at the Planck scale? Fermilab scientists have been conducting experiments to look for quantum fluctuations of space and time at the smallest ...

The Planck Telescope: News From the Dawn of Time Will a new picture of the universe’s first light overturn a theory that has reigned for 30 years?

No matter how much evidence there is supporting their existence, black holes remain firmly in the realm of theoretical physics. Because of their properties—their structure, the fact that they ...

Planck will map the relic light of the Big Bang to learn more about the universe in its infancy.

If black holes are really Planck stars, Nikitin wrote, and they are constantly emitting a stream of dark matter, they could explain the motions of stars within galaxies.

Whether or not there is some length of time smaller than the Planck time is up for debate, since neither quantum mechanics nor relativity can explain what happens below that scale.

Therefore, the constants of the universe can be reduced to only two quantities: Planck length and Planck time,” the researchers note.

Physicists have proposed a new model of space-time that may provide the 'first observational evidence supporting string theory,' a new preprint suggests.
