Our best observations can't come up with a single answer for how quickly the universe is expanding. Maybe that's because our galaxy is at the center of a giant void. When you purchase through links on ...

The universe’s expansion makes galaxies move away from each other. The further away they are from us, the more quickly they move. The relationship between a galaxy’s speed and distance is governed by ...

Imagine waking up one day to find out you live inside a vast, invisible bubble — a region of space so vast it stretches a billion light-years across, and yet so elusive it leaves no visible boundary.

In recent years, one of the most troubling puzzles in astrophysics has grown more urgent. Scientists have realized that the universe seems to be expanding faster than expected, throwing a wrench into ...

Sound waves 'fossilized' in the arrangements of galaxies across the Universe support the theory that the Milky Way galaxy floats adrift in a giant void in space. If this is the case, we could be ...

The Milky Way galaxy in which our solar system lies may exist in a "giant void", where space is about a fifth as dense as the universal average. This is the conclusion of a team of researchers from ...

Could it be that the nature of the universe is tricking us, merely because of our location? The ongoing “Hubble tension” the intransigent discrepancy between the universe’s local and cosmic expansion ...

One of the biggest mysteries in cosmology is the rate at which the universe is expanding. This can be predicted using the standard model of cosmology, also known as Lambda-cold dark matter (ΛCDM).
