How was the universe created from nothing?
The Universe as we observe it today began with the hot Big Bang: an early hot, dense, uniform. Perhaps, according to cosmic inflation — our leading theory of the Universe’s pre-Big Bang origins — it really did come from nothing.
Who is Creator of Universe?
A creator deity or creator god (often called the Creator) is a deity or god responsible for the creation of the Earth, world, and universe in human religion and mythology. In monotheism, the single God is often also the creator.
What existed before the universe?
The initial singularity is a singularity predicted by some models of the Big Bang theory to have existed before the Big Bang and thought to have contained all the energy and spacetime of the Universe.
Does the universe end?
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 it theoretically possible to travel back in time?
Time travel to the past is theoretically possible in certain general relativity spacetime geometries that permit traveling faster than the speed of light, such as cosmic strings, traversable wormholes, and Alcubierre drives.
How does time exist?
Einstein’s general theory of relativity established time as a physical thing: it is part of space-time, the gravitational field produced by massive objects. The presence of mass warps space-time, with the result that time passes more slowly close to a massive body such as Earth.
How did space time start?
An expanding Universe could have originated from a singular point — an event in spacetime — where all of space and time emerged from a singularity. The Universe could be expanding today because it was contracting in the past, and will contract again in the future, presenting an oscillating solution.
Are there other universes?
There is not one universe—there is a multiverse. In Scientific American articles and books such as Brian Greene’s The Hidden Reality, leading scientists have spoken of a super-Copernican revolution.
Does the present exist?
One way of seeing this is to recognize that the notion of “present,” as sandwiched between past and future, is simply a useful hoax. After all, if the present is a moment in time without duration, it can’t exist. What does exist is the recent memory of the immediate past and the expectation of the near future.
How many dimensions does a triangle have?
You are very close. A flat shape is called a two-dimensional shape because it has two dimensions (in the case of a triangle they are often called base and height) while a three dimensional shape will have three dimensions.
