Before stars formed, the Universe lacked oxygen; only after nuclear fusion did heavier elements emerge.

New findings challenge long-held beliefs about dark energy and the cosmos' expansion, signaling potential revisions to the standard cosmological model.

Dark energy is potentially not a constant force but a changing phenomenon that could alter our understanding of the universe's expansion.

Andromeda's satellite galaxies are uniquely lopsided, challenging current theories of galaxy formation.

Wormholes could allow humanity to travel across vast distances in space almost instantaneously.

Dark matter, making up over a quarter of the universe, is a crucial but unseen component influencing celestial motion.

Lisa Randall's theories on extra dimensions and dark matter significantly impact cosmology and propose ideas complementing Einstein's theory.

Berkeley Lab's findings suggest dark energy may be an evolving form of matter, challenging the concept of it as a universal constant.

The universe's fate may change as dark energy appears to be weakening, possibly leading to varied future scenarios.

New data from DESI may provide crucial evidence supporting the variable nature of dark energy.

The laws of physics remain consistent across all times and locations despite complex interactions and limitations at the Planck scale.

Cosmology integrates subatomic particles and cosmic structures, showcasing the universe's evolution through Einstein's theories of General Relativity and the Friedmann equation.

A new theory suggests the universe began through multiple rapid bursts of energy rather than a single Big Bang explosion.

A new theory proposes that the universe may have originated from a gravitational crunch rather than the Big Bang.

Black hole cosmology offers a radical alternative to the standard model of cosmology, suggesting the Big Bang occurred within a black hole.

Gravity may indicate we are living in a virtual simulation, according to physicist Melvin Vopson.

Researchers have precisely measured the maximum mass of neutrinos, advancing understanding of subatomic physics and the universe's expansion.

The Universe's fundamental properties may be inherently unstable, leading to the potential decay of its structure.

Dark energy may not be a constant; it's changed over time, challenging current cosmological models.

The Hubble tension has intensified, suggesting a persistent discrepancy in the universe's expansion rate calculations.

Recent studies indicate dark energy's behavior might be evolving, complicating the Hubble tension further.

The chance of intelligent life in the universe is lower than public perception, with new research estimating it at 27% outside our galaxy.
