The researchers found that two other nearby galaxies — the Large Magellanic Cloud and Messier 33 — could have significant influence on whether the Milky Way and Andromeda ultimately collide.

(CNN) — Astronomers have for the first time spotted two galaxies in the throes of a deep-space “duel.” Using combined observations from ground-based telescopes over nearly four years, the ...

Astronomers witnessed two galaxies engaged in an intense deep-space battle for the first time. Watch the “cosmic joust” in action.

Astronomers witnessed two galaxies engaged in an intense deep-space battle for the first time. Watch the “cosmic joust” in action.

An image taken by the Atacama Large Millimeter/submillimeter Array (ALMA) shows the molecular gas content of the two galaxies involved in the cosmic joust.

Compression would be expected. And law – that is, gravity – would be expected to emerge from these computational rules. We may not yet have definitive evidence that we live in a simulation.

Gravity may not be a fundamental force of nature, but a byproduct of the universe streamlining information like a cosmic computer.
