How does the universe exist?
The Big Bang theory is the prevailing cosmological description of the development of the universe.
According to estimation of this theory, space and time emerged together 13.799±0.021 billion years ago and the energy and matter initially present have become less dense as the universe expanded..
What is Canon fanfiction?
In fiction, canon is the material accepted as officially part of the story in an individual universe of that story. It is often contrasted with, or used as the basis for, works of fan fiction.
How long will the universe exist?
Assuming that dark energy continues to make the universe expand at an accelerating rate, in about 150 billion years all galaxies outside the Local Supercluster will pass behind the cosmological horizon.
Who first proposed parallel universe?
One evening in 1954, in a student hall at Princeton University, grad student Everett was drinking sherry with his friends when he came up with the idea that quantum effects cause the universe to constantly split. Read more: “Multiverse me: Should I care about my other selves? “
Are there other universes?
Together, these universes comprise everything that exists: the entirety of space, time, matter, energy, information, and the physical laws and constants that describe them. The different universes within the multiverse are called “parallel universes”, “other universes”, “alternate universes”, or “many worlds”.
Is the universe infinite?
The observable universe is still huge, but it has limits. … That’s because we know the universe isn’t infinitely old — we know the Big Bang occurred some 13.8 billion years ago. That means that light has had “only” 13.8 billion years to travel.
How flat is the universe?
The exact shape is still a matter of debate in physical cosmology, but experimental data from various independent sources (WMAP, BOOMERanG, and Planck for example) confirm that the universe is flat with only a 0.4% margin of error.
Are there different dimensions?
The world as we know it has three dimensions of space—length, width and depth—and one dimension of time. But there’s the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions.
What is alternate universe in fanfiction?
ALTERNATE UNIVERSE (also known as alternate reality), is commonly abbreviated as AU and it is a descriptor used to characterize fanworks which change one or more elements of the source work’s canon. the term most often refers to fanfiction, but fanart can also depicted the characters in AUs.
Do black holes exist?
There is consensus that supermassive black holes exist in the centers of most galaxies. The presence of a black hole can be inferred through its interaction with other matter and with electromagnetic radiation such as visible light.
What is an example of a parallel universe?
The hyperspace of science fiction is a parallel universe which allows for faster than light travel between two entry points in our universe.
Is there an end to the universe?
The end result is unknown; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity).
Is there an 11th dimension?
The 11th dimension is a characteristic of space-time that has been proposed as a possible answer to questions that arise in superstring theory. The theory of superstrings involves the existence of nine dimensions of space and one dimension of time (a total of 10 dimensions).
What does AU mean in anime?
alternative universeAn alternative universe (also known as AU, alternate universe, alternative timeline, alternate timeline, alternative reality, or alternate reality) is a setting for a work of fan fiction that departs from the canon of the fictional universe that the fan work is based on.
