Somewhere during P2 GLaDOS states that you only have 60 (I think) years of your life left. It can be assumed that you've slept for way over 20 years. At the beginning of P2 you're in a bed and wake up periodically, but something happens and you're stuck for more time than the clock can track (hence in not rolling over). The events of HL1 and HL2 are 20 years apart. I wouldn't say they happen at the same time. Either way it signals how the two companies and more importantly stories are intimately linked. The resistance decide from this and now decrypted photos and blue prints that whatever Aperture science developed and is now on the Borealis is either going to be a powerful weapon against the Combine, or too dangerous to be left in the hands of the combine. If the site is where we think it is, then it should be no more than. We'll need to take a close look at it, of course, but I should be able to give a better opinion within a few hours. It's hard to say how much of it might have survived intact, or whether there's anything remaining that could compromise our work. I'm fairly sure I've pinned down the location of the Project. Years later, Judith Mossman, Resistance operative, finds the Borealis and sends a message to that effect to the resistance in White Forest. According to Isaac Kleiner, Aperture was working on a promising project, but in their rush to beat Black Mesa for funding, they neglected ordinary safety rules and the ship simply disappeared with parts of its drydock, which earned it an almost legendary stature. The Borealis is an Aperture Science research vessel introduced in Half-Life 2: Episode Two. Some time before the 7-Hour war (circa 1970, from Portal 2), it is found out that Aperture science is close to completing/advancing their portal technology, sans safety checks: The supposed delay in the teleportation of Gordon is due to interference from the combine teleporter being destroyed, otherwise teleportation as developed by Black Mesa is also instantaneous.

In effect the teleportation swings by Xen, and arrives elsewhere on earthĬonversely the teleportation technology developed by Aperture Science is based on portal technology and is in essence instantaneous. Single dimensional teleportation is seen in the second chapter of Half-Life 2, Red Letter Day when the resistance tried to teleport Gordon Freeman to a separate base, and achieved by factoring in 'Dark Energy equations'. ~Half Life Wiki (referencing game events) Teleportation was a major field of study at Black Mesa, and their portals were used primarily in the procurement of Xen crystals, as they were used to transport scientists to and from the Borderworld for research and analysis. As well as this, the dry dock for the Borealis is seen in Portal 2. If you wander around the correct locations in Portal one you see there various slides from presentations that hint at a rivalry between the two companies, both of which were working on similar projects. The Borealis (containing some Aperture Science portal technology) is sought out by the resistance (remnants of Black Mesa and newly freed citizens) for various means.
#WHAT HAPPENED BETWEEN HALF LIFE 1 AND 2 SERIES#
Black Mesa and Aperture Science, the two focal science companies of the Half-life and Portal series exist in the same in-game biverse and, at one point vied for research funding.
