What we saw in the DESI experiments, and now strengthened by our South Pole Telescope observations, is that dark energy is ...

A new cosmological simulator logs its scientific predictions and refutations in real time, storing hashes in blockchain with full offline ...

Based on the new model, the first of these white dwarf explosions isn’t due for at least 10 1100 years. That’s a 1 followed by 1,100 zeros—a number so big that we don’t have a name for it ...

Some physicists think our reality is a kind of cosmic hologram, with space, time, and gravity as manifestations of a ...

The universe seems to be spinning, and that could explain what dark energy is and why it's weakening while revealing our ...

A new cosmological theory is challenging the traditional Big Bang model by proposing that the universe originated from a ...

Under the right conditions, this collapse doesn’t end in a singularity — instead, it bounces and begins expanding again,” said University of Portsmouth professor Enrique Gaztañaga in a statement that ...

Is the Hubble constant—a key part of how we measure the expansion of our universe—in a crisis? Some cosmologists say yes.

The icy, desolate landscape of Antarctica, a continent synonymous with extreme cold and scientific isolation, might be harboring a secret that could fundamentally alter our perception of the cosmos.

Black holes are expected to be the last giant objects left in the universe, but even they will slowly shrink and disappear ...

The new measurements with the South Pole Telescope enable more precise constraints on our cosmological models. In particular, the data tighten our measurement of the sound horizon scale 13.8 billion ...

Analysis of DESI’s earlier work, now supported by the South Pole observations, suggests that dark energy is growing weaker over time, and that universal expansion could eventually halt. Additionally, ...
