Dark Energy

Long thought to drive the universe's accelerated expansion, dark energy is now questioned, with groundbreaking research suggesting it may not exist.

Timescape Theory

Scientists from the University of Canterbury propose the "timescape model," explaining expansion without invoking dark energy, published in Monthly Notices of the Royal Astronomical Society Letters.

Gravitational Time

Time moves slower in stronger gravitational fields, like Earth’s, creating the illusion of faster cosmic expansion in voids between galaxies.

Supernova Clues

Researchers analyzed light from Type Ia supernovae to compare cosmic expansion models, finding timescape theory provides better predictions than dark energy.

Hubble Evidence

Hubble and James Webb telescopes confirmed galaxies’ rapid movement, contradicting dark energy's constant force, leading to new investigations.

Cosmic Void

The timescape model suggests voids between galaxies expand faster than denser areas, creating the perception of accelerated cosmic growth.

Decades Unveiled

Lead researcher Professor David Wiltshire claims these findings resolve decades of mystery around the universe's accelerating expansion.

European Space Agency

Future Confirmation

The European Space Agency’s Euclid satellite will gather high-quality data to confirm or refute the timescape model within a decade.

Galaxy

Mystery Rewritten

If proven, the timescape model would replace dark energy in explaining universal expansion, fundamentally altering our understanding of the cosmos.
