Current best theories suggest that small galaxies should be distributed around their host galaxies in random circles.

Vice reports that the smaller galaxies arrange themselves in thin disks around their hosts. That is a puzzling gap between knowledge and theory.

Researchers are trying to reconcile the gap by suggesting that smaller galaxies may be created by a new class of particles called symmetrons.

The universe is made up of three key components: the cosmological constant, which is a coefficient added by Einstein, and cold dark matter, which are slow moving particles.

The theory suggests that smaller galaxies should be captured by larger host galaxies and forced into chaotic orbits, something that has not been seen in real world observations.

Two researchers from the University ofNottingham may have come up with an explanation in a new study.

They think that a fifth force could be arranging the galaxies into disk shapes, while still considering the existence of dark matter.

Their theory states that speculative particles known as symmetrons, which have been used to explain gaps in our knowledge of the universe, could generate this force to form domain walls.

We know that we need new particles because we have dark matter and dark energy and so we suspect that we're going to need to add new particles to our standard model.

It is a new particle candidate for dark energy and/or dark matter and is being studied by people.

These particles can be found in groups of different polar states. These walls could cause smaller galaxies to form disks around larger host galaxies.

Many questions remain and Naik and his colleague University ofNottingham physicist have a lot of work to do to solidify the theory.

Scientists propose that space has invisible walls.

A scientist says dark matter could be an amazing fuel for spacecraft.
