In the opening scene of Captain America: The First Avenger, you see Johann Schmidt (Hydra founder) bulldoze his way in an establishment. He finds Tesseract in a wooden box carved into a tree that denotes Yggdrasil. You must be thinking: What is Yggdrasil?
It is the world tree. Guardian of wisdom and fate. It connects nine realms. You will find its imprint on Heimdall’s chest too.
Now lets come to Tesseract.
The Red Skull claims that the Tesseract was one of Odin’s crown jewels, and that it is an example of mythology and science being combined.
Only once in recorded history has the power of all six stones been harnessed. This was achieved by six cosmic beings, each with one stone, linking themselves together.
The effects were short-lived as the energy of the stones disintegrated all six beings after a few short moments.
I don’t know who these cosmic beings were and hope that Marvel covers it thoroughly either in a movie or a series.
The stone in Tesseract is the “Space” stone.
Space stone has almost unlimited power. It can wipe out a planet just like that.
The Tesseract can open rifts through space. This is how Loki transported himself and later, the Chitauri, to Earth through portals. In other movie Thor and a restrained Loki uses the Tesseract to teleport back to Asgard.
Tesseract-powered weapons are particularly devastating, as a single shot could completely disintegrate an opponent. You have seen this in Captain America: The First Avenger.
Tesseract can harness and channel a seemingly unimaginable amount of field quanta to protect itself from being attacked by other energy sources. (So in the “intuitive” or “experimental” language, quanta of quantum fields are the actual particles (such as photons, Higgs bosons, or electrons). They’re what the quantum fields are able to create (and annihilate)).
As seen when the field region, surrounding the Tesseract, proved to be completely impervious to Iron Man’s repulsor beams. This means the objects barrier is pure energy.
The Tesseract can also show visions of the future, which may or may not come true.
It cannot be held by mortal hands. Anyone who does so will be disintegrated, their remains sent to another world, as evidenced with what happened to Red Skull. (So he is alive in some other realm.)
While the Tesseract is shown to burn living flesh, it apparently has no effect on dead wood – it was stored in a secure way in a wooden compartment for centuries as showed at the start of Captain America: The First Avenger.
A Tesseract, commonly called a hypercube, is a 4-dimensional cube. The Tesseract shows some possibly “4th dimensional” qualities, such as: teleporting objects, seemingly through a fourth dimension; being able to call up massive amounts of cosmic energy, seemingly out of another dimension; Howard Stark draws the Hypercube as a four dimensional cube, as a cube within and connected to a larger cube. Below is an example image.
