Cosmology
Cosmology is the area of physics that studies the universe in and of itself. Through the use of incredible and ingenious methods of experimentation, cosmologists attempt to discover how the universe began, how it is developing, and how or if it will end. Questions regarding the Big Bang, dark matter, dark energy, the cosmic background radiation, and the initial formation of the fundamental particles can be placed into this category.

The four components of which the entire physical universe exists?
The four dimensions of the universe sre Quaternions: w + Ix +Jy + Kz where (w,x,y,z) are real numbers and the I,J and K are vectors as defined by William Rowan Hamilton, I2 = J2 = K2 = IJK = -1. Thus there are three vector dimesnions and one real dimension. Space dimensions are measured in meters.
The real dimension w, can be related to time thru a speed variable such as the speed of light, w=ct. Time is a real variable not a vector variable like the three space dimensions.
What word is used for universe payback?
"Karma" is the word typically used to describe the concept of the universe delivering consequences or payback based on a person's actions or intentions. It is the idea that one's actions will eventually come back to them, either positively or negatively.
Dark energy is an unexplained force that is causing?
Dark energy is a mysterious form of energy that is causing the accelerated expansion of the universe. It is thought to make up about 68% of the total energy content in the universe, but its exact nature and origin remain unknown to scientists.
Can super tengen toppa guren ladgann destroy a universe?
Super Tengen Toppa Gurren Lagann's size and power suggest it could potentially destroy a universe, but the extent of its destructive capabilities is not explicitly stated in the series. Its attacks demonstrate immense power, capable of causing significant damage on a large scale.
Which structures make up the universe?
The universe is composed of various structures such as galaxies, stars, planets, black holes, nebulae, and dark matter. These structures interact with each other through gravitational forces and other physical laws to form the vast and complex cosmos we observe.
Nitrogen family member with 15 neutrons?
Phosphorus from IAmArchangel, but i wasn't signed in at the time
The term Rubenesqueis used to describe?
The term "Rubenesque" is used to describe a woman who is full-figured or plump, typically with voluptuous curves resembling those portrayed in the paintings of the artist Peter Paul Rubens. The term celebrates and appreciates larger body types.
Dark matter is not visible to the naked eye and does not emit, absorb, or reflect light, so it does not have a color like visible matter. It remains invisible and undetectable through traditional telescopes, which is why it is called "dark" matter.
Is the universe in the milkyway?
..What..?
The univere is EVERYTHING, including the milky way galaxy.
The big bang theory and origin of the Earth?
The Big Bang theory is the leading explanation for the origin of the universe, suggesting that it began as a extremely hot and dense point roughly 13.8 billion years ago. The Earth formed about 4.5 billion years ago through the accretion of dust and gas in the solar system as it cooled down.
A star is considered the building blocks of the universe why?
Consciousness in its pure state
Then it is sensed as energy
Right from energy matter gets projected as space and time emerge out of consciousness
So we have a fantastic ground to play
Finally to get merged within pure consciousness, self realization process is essential.
launched in 1989 by NASA
studied cosmic background radiation
viewed in infrared and microwaves
it was a space telescope and needed to be kept cool as it observed in infrared
wasn't very sensitive but it confirmed ideas about early universe
finished it's mission in 1993
Are there 50 suns in the universe?
No, there are not 50 suns in the universe. Our solar system has one sun, which is a star that provides light and heat to the planets. There are billions of other stars in the universe, but not all of them are like our sun.
Has the big question about the origin of the universe finally been answered?
No. We have some theories that explain important aspects about how the Universe began. The current theories and understandings that we have get to fractions of second after the beginning, but we still have not gotten to the beginning yet.
As to any purpose of the universe, science has not attempted to even discern such a thing.
A long time ago people believed that the - blank - was the center of the universe?
A long time ago, people believed that the Earth was the center of the universe, a theory known as the geocentric model. This idea was eventually replaced by the heliocentric model, which places the Sun at the center of the solar system, proposed by astronomers like Copernicus and Galileo.
What is the best color in the universe?
In astronomical terms the coldest colour is black as no energy is radiated.
From coldest to hottest, the colours are (With many variations in between)
Black
Brown
Red
Orange
Yellow
White
Blue
lime green
Star-star connection of transformer?
Star Star Transformer
Star Star Transformer is formed in a 3 phase transformer by connecting one terminal of each phase of individual side, together. The common terminal is indicated by suffix 1 in the figure below. If terminal with suffix 1 in both primary and secondary are used as common terminal, voltages of primary and secondary are in same phase. That is why this connection is called zero degree connection or 0o - connection.
If the terminals with suffix 1 is connected together in HV side as common point and the terminals with suffix 2 in LV side are connected together as common point, the voltages in primary and secondary will be in opposite phase. Hence, Star Star Transformer connection is called 180o - Connection, of three phase transformer.

Actually, no on both counts.
The redshift is a DIRECT measure of the fact that distant objects are moving away from us. It IMPLIES the expansion of the universe, but doesn't directly measure it.
Also, even if it were, it wouldn't necessarily be independent of direction. One recent study indicates that it might not be, which (if true) means the Universe is not expanding isotropically.
Dark matter is inferred to exist because?
Dark matter is inferred to exist because of the gravitational effects it has on visible matter in the universe. Observations of galaxies rotating faster than expected and the bending of light around massive objects support the presence of dark matter. However, dark matter itself has not been directly observed or detected.
The geocentric view was captured in Ptolemy's model in ancient times, and it was not until 1543 that Copernicus brought out an alternative heliocentric model with the Sun at the centre. He claimed that the new model was geometrically simpler, and there were good reasons for that view. Both these models used circles and epicycles to explain the planets' observed movements among the 'fixed' stars, and they were both fairly accurate.
In 1609 Kepler published yet another heliocentric model that had the planets in elliptical orbits. The new model fitted a new set of highly accurate observations by Tycho better than the old models. However there was at that time no way to decide which model was correct, other than the better accuracy of Kepler's theory.
Within the next 100 years the law of gravity and the laws of motion were discovered, and Newton demonstrated theoretically that the planets must move in elliptical orbits under the Sun's gravity. Within the next 100 years after that the distance to Venus was measured and the dimensions of the whole solar system could then be calculated.
It was then possible to show that the Sun is far more massive than the planets, and therefore it must be at the centre.
The final discovery of stellar parallax in 1838 demonstrated that the Earth actually moves around the Sun. After that no-one could credibly deny the heliocentric idea.
Where did the universe come from scientist point of view?
Neptune was created by many gases that formed into one big planet. They say Neptune was also created by the big bang theory. The gases are called hydrogen, helium, water, and ammonia.
Improvement:
Just to clarify - the gases actually formed into one big planet as a result of the Big Bang Theory.
Is dark matter a state of matter?
No, it is not.
Dark matter is a slightly more scientific way of saying "hypothetical stuff that we know almost nothing about, but imagining that it exists is easier than rewriting all of physics, especially since we know from experience some of the physics we'd have to rewrite actually works fine just as it is." We really don't know what dark matter is exactly (there are a few different theories, and it's quite possible that it's a little from Column A and a little from Column B), we just know that either it has to be there or we don't understand large-scale physics nearly as well as we thought we did.
What are 3 synthetic elements?
Three synthetic elements are technetium (Tc), promethium (Pm), and neptunium (Np). These elements do not occur naturally on Earth and must be produced artificially through nuclear reactions in laboratories.
Is your observale universe always the same size?
The observable universe is constantly expanding due to the ongoing expansion of the universe. This means that the size of the observable universe is not constant and will continue to increase over time.
What is the big bang theory in depth?
The BIG BANG is a theory that says that the universe, about 14 billion years ago, was a single point from which space, time, matter and energy and everything was created.
It's a little misleading to think of it as an "explosion". There wasn't a bunch of space into which the explosion propelled "stuff", the big bang actually created the space. This is a hard concept for kids (or, for that matter, anyone) to wrap their heads around, and there really isn't a good way to make it much simpler than that.
