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.

Galaxy types from largest to smallest type?
It doesn't really work that way. The types aren't exactly related to size, but rather to shapes. Dwarf galaxies of course are the smallest; but other than that, a spiral galaxy can come in different sizes; so can an irregular galaxy or an elliptical galaxy.
What names are derived from these words for the people who study astronomy and cosmology?
An astronomer.
Ans 2.
An astronomer studies anything that is not on earth; many astronomers study the moon, or one or more planets, or the solar system as a whole. The study of the Universe as a whole is cosmology; the person who studies it is a cosmologist.
What does the big bang refer to?
Colllected particles from the Primordial atom(large sphere)burst out this was big bang.Sun was a part of it.A star came near the sun pulled some things out of it.these were the planets of the solar system.
What are facts about the observational approach to cosmology?
The observational approach to cosmology involves studying the universe by observing and analyzing objects and events in space, such as galaxies, stars, and cosmic background radiation. Observational cosmologists use telescopes, satellites, detectors, and other instruments to collect and analyze data to study the large-scale structure and evolution of the universe. By observing the light and radiation emitted by celestial objects, scientists can gather insights into the composition, expansion, and history of the universe.
The Cosmic Background Explorer (COBE), also referred to as Explorer 66, was a satellite dedicated to cosmology. Its goals were to investigate the cosmic microwave background radiation (CMB) of the universe and provide measurements that would help shape our understanding of the cosmos.
What does Hattie Owen look like?
Hattie Owen is a character in the book "Hattie Big Sky" by Kirby Larson and her physical appearance is not specifically described in detail. She is portrayed as a young girl who is independent, determined, and resilient.
Is it true the Big Bang was equal to 1 CNRhK?
The Big Bang is a scientific theory that explains the origins of the universe and is not typically equated to a specific quantity like 1 CNRhK. The theory describes the rapid expansion of space and time from a singularity, leading to the formation of all matter and energy in the universe.
Dark matter can be detected by its?
Dark matter can be detected by its gravitational effects on visible matter and light. It does not emit, absorb, or reflect light, making it invisible to telescopes. Scientists use indirect methods like gravitational lensing and measuring the rotational speeds of galaxies to study and detect the presence of dark matter.
Refractive glass what is refractive glass?
Refractive glass is a type of glass that has special properties to bend and control the path of light passing through it. It is used in lenses and optical devices to focus or magnify light by refracting it. This property of glass is essential in optics and photography.
What is the speed of your milky way away from the big bang?
Your question betrays a common misconception about the Big Bang, not helped by sloppy explanations by scientists and by popular media presentations.
The BB was NOT an explosion of matter into empty space, expanding outward from a point. It was, instead, and expansion of space itself, with matter coming along for the "ride." Our galaxy is NOT moving "away" from anything, it's not really moving very much at all -- it's just that the space between the Milky Way and all other galaxies is expanding.
Because the BB was an expansion of all space, everywhere, it occurred everywhere. There is no place in our Universe that we can point to and say, "From that place the BB started." If this were not the case, the cosmic microwave background radiation would have a preferred direction -- instead, it's isotropic to one part in 10,000 . In other words, no point in the sky has more than .01% greater intensity of CMBR than any other point.
How can the big bang still be visible?
Light actually takes time to move, so light that was 13.7 billion light years away would just recently be visible, and we may be able to see the remnants of the big bang. many scientists predict that because they have predicted the universe is expanding and if you look back it makes sense that it all started at 1 point then.
Cosmic order refers to the belief in a universal system or structure that governs the behavior and events in the universe. It is the idea that there is a natural balance and harmony in the cosmos, and everything is interconnected and follows certain laws or principles. This concept is often found in various spiritual and philosophical traditions.
Is the ratio of a quark to a human greater or less than the ratio of a human to the known universe?
It may be better to think about this in terms of mass.
An average human is about 70kg.
A photon is about 4.2x10^-40 kg.
The local group of galaxies including the Milky Way is about 2.5 x 10^42kg.
The known universe is approximately 3 x 10^52 kg.
This implies that the known universe is larger, but for all intents and purposes the size difference in eitherdirection is incomprehensibly large.
A polling universe refers to the specific group or population that a poll or survey aims to capture data from. It represents the targeted demographic or participants that researchers want to gather opinions or information from. Defining the polling universe helps ensure that the data collected is representative and relevant to the research objectives.
What is the process of breaking a vector into its components is called?
The process of breaking a vector into its components is called vector resolution. It involves separating the vector into perpendicular components along specified axes (usually x and y axes). This is often done in order to simplify vector calculations and analyze the effects of different forces acting on an object.
How old is Sheen from Jimmy Neutron?
In the show, Sheen is depicted as being around the same age as Jimmy Neutron, which is about 10 years old.
What is big bang necleosynthesis?
Nucleosynthesis. It refers to the formation of atoms larger than Helium-1. Because of the extreme conditions right after the Big Bang, it is believed that some Deuterium and Helium were formed, perhaps some Lithium too; but no significant amounts of other metals. (In Astronomy, a metal is any element heavier than Helium.)
What is individual vs universe?
Individual vs. the Universe involves a character and his struggle to find a place in the Universe. For example: lets say there is a story about an alien duckling that believes he is an alien swan until he is abandoned and can't find out why, yet he searches to find out how to get back to his family(unexpecting that he may or may not find out which group he belongs to later on in the story) He finds out later in the story that he is an alien duck and not a swan. Realizing that he is meant to be with the group of alien ducks, therefore, finding his place in the universe
Do they still show jimmy neutron in nicktoons?
yes the do they are on weekdays @ 1pm and 1 30pm and sometimes it is Invader ZIM
As water is cooled 4c to 0c its density?
the density of water is mostly high when its at 4 degrees celsius so the answer would be that the density of the water decreases from 4 degrees celsius to 0 degrees celcius
No, dark matter could not be explained by things like planets, space debris, asteroids and other matter we see in our solar system. Follow along as we wander through some facts that we have observed and let's see where we end up.
The effects of dark matter are huge as it is demonstrated to be a source of massive gravity. The gravity is so massive that it literally affects the rotation of whole galaxies. Also, only mass generates gravity. We know most of the mass of galaxies is made up of stars and something else distributed among those stars that is equally massive, but is invisible.
Consider that over 99.9% of the mass of the solar system is held in the sun. That leaves little else with mass in the whole rest of the solar neighborhood, including all the planets and everything else. There is no reason to think that things are much different around other stars in a galaxy. Also consider systems where double stars appear. They are actually fairly common, so in systems where a star appears and a lot of extra material is left, another star appears as a result. But as regards galaxies, something is distributed among them to cause them to rotate the way they do, and we can't see it. The "stuff" is matter (mass, which generates gravity), and is dark (emits no light), so we call it dark matter.
The "wondering" behind the question is excellent, but there is no way to suppose that the "extra stuff" outside the star in any solar system would have enough mass to play against that of the star in that system. But with some more thinking, perhaps an explanation of what dark matter really is can be found. There is a Nobel Prize to the person who can explain it, or at the very least a nomination. Count on it.
Who proposed a mechanical universe with small solid masses in motion?
Rene Descartes proposed a mechanical universe with small solid masses in motion. He believed that all natural phenomena, including the motion of planets and stars, could be explained through the interaction of these small solid masses.
What evidence supports the pulsating universe theory?
the pulsating universe theory is when the universe expands (the big bang) then contracts (the big crunch) and so on (it's pulsating). according to this theory right now the universe is expanding, but then it will contract
Man is a universe within himself?
This phrase suggests that each person contains a vast array of experiences, emotions, and thoughts within themselves, much like the universe is vast and complex. It highlights the depth and complexity of individuals and the idea that we are capable of incredible exploration and discovery within our own beings.
