A slipspace anomaly is an unusual event that occurs in slipstream space. Several abnormal slipspace behaviors could be categorized as slipspace anomalies. Slipspace anomalies are very rare and can put a craft's ability to transition safely into Slipspace in jeopardy.

Time dilation

There is anecdotal evidence that the normal laws of nature "bend" in close proximity to an active Shaw-Fujikawa drive. Slipspace has always been known to exhibit discrepancies between those who entered and those who remained outside. On occasion, ships might arrive days or even weeks before they're scheduled to. In some rare and usually classified instances, ships have been tracked arriving at one location before they've even entered slipspace at another.

Time-space rip

One slipspace anomaly occurred in 2552, in which a Forerunner artifact carried by the UNSC Apocalypso created a giant rip in both realspace in Lunar orbit and in Slipspace. The rip acted as a portal between the years 2552 and 2004, sending part of the Apocalypso's shipboard AI construct, Melissa, through it. In addition, all communications within the Sol system were silenced for over seven seconds. When the artifact was deactivated several weeks later, the rip closed and the AI was sent back to 2552.

Space bubble

The Forerunner crystal found in the Menachite portal complex on Reach, coupled with Cortana's incorrect Slipspace calculations also created a Slipspace anomaly. This anomaly caused the ship the artifact was in, as well as all surrounding ships, to enter an anomalous Slipspace dimension when transitioned into Slipspace. One could fire their weaponry in this sub-dimension, but Covenant ships could not recharge their shields. Shots fired did not obey the standard laws of physics and instead disappeared and reappeared in different locations until they hit something. There was also fog present in the bubble, instead of the black nothingness of normal Slipspace.

The Forerunner Dreadnought's wake

On November 3, 2552, after witnessing the aftermath of the Battle of Installation 05 and the beginning of the Great Schism, the crew of the UNSC Dusk set course for Earth. The prowler arrived at Earth within hours by following the Slipspace wake of the Forerunner Dreadnought. Strangely, the Dreadnought did not arrive in the Sol system for a further five days, and it did not arrive at Earth until November 17.
