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.

Can scientific inquiry study further back in time than the big bang?

User Avatar

Asked by Wiki User

No, scientific inquiry cannot study events that occurred before the Big Bang. The Big Bang is the origin of the universe and the laws of physics as we know them. Anything before that is currently beyond the realm of scientific investigation due to the limitations of our current understanding and technological capabilities.

How is the universe changing by cosmic microwave background radiation?

User Avatar

Asked by Wiki User

The cosmic microwave background radiation (CMB) represents the afterglow of the Big Bang and provides valuable information about the early universe. As the universe expands, the CMB wavelength is stretched, causing it to cool and become less energetic over time. This gradual decrease in temperature corresponds to the universe cooling down and evolving into its current state.

Why was it necessary that the universe cool down before plants could form?

User Avatar

Asked by Wiki User

It was necessary for the universe to cool down before plants could form because plant life requires stable temperatures within a certain range for survival. If the universe remained hot, it would have been too hostile for the emergence and sustenance of plant life. Cooling down created an environment suitable for the development and evolution of plants.

How does redshift connect to cosmic bakcground radiation?

User Avatar

Asked by Wiki User

Redshift refers to the stretching of light waves towards longer wavelengths, which occurs when an object is moving away from an observer. Cosmic background radiation, also known as the cosmic microwave background (CMB), is residual radiation from the early stages of the universe that has been redshifted over time and is now observed as microwave radiation. The redshift of the CMB provides strong evidence for the expansion of the universe and supports the Big Bang theory.

How cosmic microwave background radiation shows us the universe is changing?

User Avatar

Asked by Wiki User

Cosmic microwave background (CMB) radiation is a remnant of the early universe, a faint glow left over from the Big Bang. By studying the CMB, scientists can determine various properties of the universe, such as its age, composition, and rate of expansion. Over time, the CMB has cooled and stretched as the universe expanded, and analyzing its temperature fluctuations provides insights into the evolving structure and dynamics of the universe. Therefore, the CMB radiation serves as a powerful tool to understand how the universe has changed and evolved over billions of years.

If God created the universe then why doesn't everything behave in a moral way?

User Avatar

Asked by Wiki User

The concept of morality is subjective and varies among individuals and cultures. The behavior of entities in the universe is governed by natural laws and principles, not necessarily moral considerations. Additionally, humans have free will, which allows for moral or immoral choices. Therefore, the existence of immoral behavior does not necessarily conflict with the idea of a creator.

How does life on earth depend on the sun?

User Avatar

Asked by Wiki User

In its natural state, solar energy is important to the earth because it warms the earth, makes plants grow, causes weather, causes water to evaporate and in turn rain, etc. The harnessing of solar energy as an alternate power source is important because it is less expensive and always available on clear days. Solar power will lesson our dependancy on other expendable resources. Solar power is a virtually pollutant free energy source.

What is the purpose of a parallel universe?

User Avatar

Asked by Wiki User

There was never a big bang until around 10,000 years after the world began this created parallel universes but the laws of gravity are different because of illusions. every 10,000 years there will be a bang to create new parallel universes

Are gamma rays stronger than cosmic ray?

User Avatar

Asked by Wiki User

Gamma rays are a form of electromagnetic radiation, and they are the highest frequency form of that type of energy. They can be said to vibrate fastest. But cosmic rays are mostly protons, which are a form of particulate radiation. Comparing gamma rays to cosmic rays as regards frequency is not something we do.

What word is used knowledge about the universe and the method of obtaining that knowledge?

Asked by Wiki User

Epistemology is a philosophical idea directed at the theories, nature, sources, and limits of knowledge. Such study would be epistemological studies.
Epistemology describes knowledge about the universe and the method of obtaining that knowledge.
omnipitent means to be all-knowing .... i think that's what you meant .......or astronomy is the study of the universe

How do red shifts were used by cosmologists to determine that the universe is expanding?

User Avatar

Asked by Wiki User

A Galaxy's red-shift can be used to determine how fast it is travelling away from you. The opposite is "blue-shift" which is what happens when the Galaxy is travelling towards you.

The first astronomers, such as Edwin Hubble, to analyse the light coming from distant galaxies discovered that almost all of them were red-shifted, indicating that they were almost all heading away from us. This was the first indication that the universe was expanding.

What is the universe's primary source of light?

User Avatar

Asked by Wiki User

The universe's primary source of light is stars. Stars are massive balls of gas that undergo nuclear fusion, generating heat and light that radiates out into space. Other sources of light in the universe include galaxies, quasars, and other celestial objects.

What evidence is there for other universes?

User Avatar

Asked by Wiki User

At the present time, nothing direct.

We have no evidence for the existence of any universe other than the one we happen to live in. The existence of others is purely speculation at this point.

However, the existence of other universes -- an almost infinite number of them, most them completely hostile to intelligent life -- would answer the question of how this universe, that we happen to live in, seems to be so well "balanced" so as to permit us to be here. If there are, indeed, an infinite number of universes, then it should be no surprise that at least one of them would allow intelligence to develop within it. The other universes simply have nobody getting upset that they can't exist there.

Why can't the so called dark matter be directly observed?

User Avatar

Asked by Wiki User

We know that dark matter exists because it got gravity, though it is invisible. It hold galaxy and Universes.

There is a theory there many other parallel universe outside our universe and dark matter holds those universe up and some scientists says that dark matter are just mass of the matter of the parallel universe. It sounds crazy but that is the Law of Physics.

However there is not exact explanation of what dark matter really is, so there are still Noble Prices for those who can come up with a reasonable explanation.

How many parallel universes are in the universe?

User Avatar

Asked by Wiki User

3, or perhaps more. It depends on the theory to which you ascribe. For example, recent research done at the Princeton Institute for Advanced Studies (IAS) led to the creation of ekpyrotic theory. According to ekpyrotic theory, our universe and its creation stems from the collision of two "branes" that could theoretically and literally represent parallel universes. According to Julian Barbour, an infinite number of parallel universes exist, since every time a decision is made on either the microscopic or macroscopic level, a bifurcation is created leading to the birth of a new "universe". Long answer short, minimally 2 parallel universes, maximally infinit.

How is the validity of the Big Bang supported?

User Avatar

Asked by Wiki User

It isn't ,it is against the laws of Phisics; One of the Laws of Physics;Conservation of Angular Momentum

e.g.If an object is spinning clockwise and bits fly off it they will also spin Clockwise as they fly off.

Try it at home!; get some Friends on a merry go round get some Strong guy to spin your freinds round clockwise and when they fly off,they will fly off spinning clockwise never anti clockwise.try it.

Anyway according to the big bang theory all the matter and planets came from the big bang.all the matter and planets should be spinning the same way off it-true?

How come Venus spins backward?

How come some moons spin backward than their planets?

How come whole galaxys spin backwards???????

If it all came of the big bang then why isn't it all spining in the same direction?

If the Big bang were true it should all be spinning in the same direction.

Transition A produces light with a wavelength of 400 nm Transition B involves twice as much energy as A What wavelenth light does it produce?

User Avatar

Asked by Votz

Energy per photon is proportional to frequency. That tells us that it's also

inversely proportional to wavelength.

So if Photon-A has wavelength of 400-nm, then wavelength of Photon-B

with twice as much energy is 200-nm .
