The universe isn’t going anywhere, scientists have confirmed.
A new study shows that the universe is expanding the same way in all directions, not spinning or stretching in any special direction.
That discovery is comforting to the cosmologists who found it – since if the universe was moving in another direction, it would put the standard model of the universe under threat.
We’ll tell you what’s true. You can form your own view.

11/30 Earth Observations From Gemini IV in 1965
This photograph of the Florida Straits and Grand Bahama Bank was taken during the Gemini IV mission during orbit no. 19 in 1965. The Gemini IV crew conducted scientific experiments, including photography of Earth's weather and terrain, for the remainder of their four-day mission following Ed White's historic spacewalk on June 3
12/30 Frosty slopes of Mars
This image of an area on the surface of Mars, approximately 1.5 by 3 kilometers in size, shows frosted gullies on a south-facing slope within a crater. The image was taken by Nasa's HiRISE camera, which is mounted on its Mars Reconaissance Orbiter

15/30 Worlds Apart
Although Mimas and Pandora, shown here, both orbit Saturn, they are very different moons. Pandora, "small" by moon standards (50 miles or 81 kilometers across) is elongated and irregular in shape. Mimas (246 miles or 396 kilometers across), a "medium-sized" moon, formed into a sphere due to self-gravity imposed by its higher mass

20/30 Launch of History - Making STS-41G Mission in 1984
The Space Shuttle Challenger launches from Florida at dawn. On this mission, Kathryn Sullivan became the first U.S. woman to perform a spacewalk and Marc Garneau became the first Canadian in space. The crew of seven was the largest to fly on a spacecraft at that time, and STS-41G was the first flight to include two female astronauts
21/30 A Fresh Perspective on an Extraordinary Cluster of Galaxies
Galaxy clusters are often described by superlatives. After all, they are huge conglomerations of galaxies, hot gas, and dark matter and represent the largest structures in the Universe held together by gravity

The HiRISE camera aboard Nasa's Mars Reconnaissance Orbiter acquired this closeup image of a "fresh" (on a geological scale, though quite old on a human scale) impact crater in the Sirenum Fossae region of Mars. This impact crater appears relatively recent as it has a sharp rim and well-preserved ejecta

This Chandra X-Ray Observatory image of the young star cluster NGC 346 highlights a heart-shaped cloud of 8 million-degree Celsius gas in the central region
“The finding is the best evidence yet that the universe is the same in all directions,” said first author Daniela Saadeh, from UCL. “Our current understanding of the universe is built on the assumption that it doesn’t prefer one direction over another, but there are actually a huge number of ways that Einstein’s theory of relativity would allow for space to be imbalanced.
“Universes that spin and stretch are entirely possible, so it’s important that we’ve shown ours is fair to all its directions.”
If the universe had been pointing in a particular direction, it would be in contrast with the assumptions of almost every cosmological study. If it didn’t behave identically in every direction, it could undermine a huge number of our existing analyses of the universe.
“We’re very glad that our work vindicates what most cosmologists assume,” said Saadeh in a statement. “For now, cosmology is safe.”
The team made the discovery by studying the cosmic microwave background (CMB) that is the radiation left over by the big bang. They modelled a number of different scenarios for a spinning or stretching universe and worked out how those might be visible in the CMB – and found that none of them matched up with the real map of the cosmos that comes from the European Space Agency’s Planck satellite.
“We calculated the different patterns that would be seen in the cosmic microwave background if space has different properties in different directions,” said Saadeh. “Signs might include hot and cold spots from stretching along a particular axis, or even spiral distortions.”
The researchers said that there was a huge number of ways that the universe could be “anisotropic”, or pointing in a particular direction. That made the work of comparing the possible examples to the real one extra difficult.

There’s still some possibility that the universe prefers one direction, the scientists said. But the precision of the new study mans that chance is just one in 121,000.
