The crack of time contains infinite 4-dimensional timelines in the form of small crystals. The destruction of the crystals is consistently juxtaposed with statements
about timelines or
the very distortion of time and space. The crystals
display images of events across time too. The crack of time is stated to contain
non-existent history. To reach prison planet,
the sky is fractured to create a crystalline rupture revealing a space with countless crystals. It's directly called
a space between dimensions.It's said to be separated yet adjoined to all dimensions.
It's a contruct that transcends time. The crack of time, where Mechikabura was sealed, was stated to be
a space beyond time. The fight against Demigra in the crack of time was called
an adventure beyond time and space. The battles there are stated to take place in
super-dimensional spaceand
hyperdimensional space multiple
times.Reaching it was described as an act of
transcending time and space. It's said to be
separated from the dimension of time. "Time" is also referred to
as an axis in Dragon Ball Heroes
multiple times.
When entering the crack of time, characters become unquantifiably larger than 4-dimensional constructs. The size of the crystals relative to the characters ranges from
somewhat larger than them to
noticably smaller than them. The crystals appear
as numerous and miniscule as endless stars. Within the crack of time, Fu
holds a distorted universe in his hand which is smaller than an arm and
monitors an infinitely small Goku from the outside.
It's far beyond the scope of the multiverse itself. After nuking the multiverse,
Demigra went to the crack of timeto be safe from the destruction. It's stated to be
out of reach for the gods and the highest in the dragon ball cosmic hierarchy, with Super Shenron's power
explicitly incapable of reaching the universe tree in it, hence it
could only destroy the rootsthat were sapping energy from universes. Even after the destruction of an infinite multiverse, no damage to the crack of time
was mentioned or visualized.
