The Tesseract through time, an MCU reference sheet
Spoilers for events including Captain Marvel and Infinity War - for all those nagging questions.
???? - The creation of the universe releases the Infinity Stones throughout the newborn expanse. Stones promptly end up in different Chili’s, but always ordering the same chicken tender platter. Also the Celestials dick around with them, which rarely ends well.
???? to founding of Asgard - early magic space viking presumably finds cool rock, and I suspect builds the Bifrost with it.
AD 965 (fixed) - Frost Giants fuck around on Earth. Odin slapshots them back to Jotunheim, discovers tiny humans really like him and his family, so he notices the planet for the only time in his entire asshole life. Probably makes mental note to hide cool shit here.
1409 - Odin hides the Tesseract/Space Stone in the Tonsberg monastery, because reasons. Monastery looks super cool, though.
1942 - Nazis find the stupid fucking thing, prepare to do dumb shit with it.
1945 - Steve Rogers kicks Johann Schmidt’s ass so hard he lands on an alien world. Steve takes a long, cold nap with his shield as his blankie and with the Tesseract close by off Greenland’s coast, meaning the ancient vikings are STILL screwing with them.
Between 1945 and 1964 - Howard Stark quietly rediscovers both body of Steve Rogers and the Tesseract. Steve remains on ice until safe revival can be performed.
1964 - Anton Vanko and Howard Stark begin the original Arc Reactor project, and we can infer by Iron Man 2 that this was based on Tesseract data.
1980′s - Aging Howard Stark introduces Project Pegasus. Dr. Wendy Lawson, actually Kree scientist Mar-Vell, accompanied by her, uh, cat, infiltrates the project for her own purposes.
1989 - The Tesseract is hidden on Mar-Vell’s vessel for unknown reasons, probably further research or a realization of its danger. Mar-Vell is killed.
1995 - Absolute goddess Carol Danvers plays tag with attacking group of Kree over the Tesseract. Goose, uh, pockets the Tesseract for safekeeping.
1995-2010s, specific date unknown - Goose has epic hork on Nick Fury’s desk. Tesseract, after a wipe-down, begins renewed study under the eye of SHIELD and the World Security Council.
2012 - Loki arrives to kick shit. Does not go well. Tesseract is returned to Asgard, where it is used to repair the Bifrost.
2017 - Tesseract survives Asgard’s destruction by virtue of being pocketed by man who lives for the occasional bit of poor decision-making.
2018 to current - Thanos ruins everything.
