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.

After the first few hundred million years after the big bang was?
After the first few hundred million years after the Big Bang, the universe was still in a hot, dense state, with elementary particles forming and ions beginning to combine into atoms. Gas clouds started to condense, leading to the formation of the first stars and galaxies. This marked the beginning of the universe's transition from a primarily uniform state to one with structures and complexity.
What kind of physicist is Shelden off of the Big Bang Theory?
Theoretical Physicist. Raj is an Astro Physicist, Leonard is an Experimental Physicist.
How much does the cast of big bang theory make?
The main cast of The Big Bang Theory was reported to be making around $1 million per episode in the later seasons of the show. This made them some of the highest-paid actors on television at the time.
What does the universe stand apone?
The universe is vast and complex, encompassing all of space, time, matter, and energy. It provides the stage for the existence and interactions of galaxies, stars, planets, and life forms. The universe is constantly expanding and evolving, with many mysteries yet to be discovered and explored.
Is plasma ionized particles in category of fluid?
Yes, plasma is considered a state of matter where the particles are ionized. Plasma is often referred to as the fourth state of matter, distinct from solids, liquids, and gases, as it is composed of ionized particles that can conduct electricity. Fluids typically refer to liquids and gases, while plasma exhibits unique properties due to its ionized nature.
What kind of radition helped prove the big bang theory to scientists?
The discovery of the cosmic microwave background radiation (CMB) played a critical role in confirming the Big Bang theory. This radiation provides strong evidence supporting the idea that the universe originated from a highly compact, hot state and has been expanding and cooling ever since.
What is the difference between many universes and many dimensions?
a) A dimension is a plane of existence or an aspect of a feature i.e. a shape or situation
b) A universe is everything that exists, it also includes itself
We experience four dimensions (length, width, height and time), but some theories (M-Theory) suggest 11-dimensions.
The geometry of our physical universe is three-dimensional.
Answer2:
a) The geometry of our Universe is four dimensional; one real dimension r=ct and three vector dimensions v= Ix + Jy + Kz. This is called Quaternion Space, the sum of a scalar or real and three vectors.
A point in our Quaternion space is p= r+ Ix + Jy + Kz = r + V = [r,V].
Relativity Theory Space-time is x + y + z + ict, this is not a four dimensional space.
)b A universe may have many dimensions. Many Universes differ from many dimensions because a Universe is different from a dimension. A dimension is a direction and a universe is not a direction.
Where is the dark lord's clone after big bang in Maplestory?
After the Big Bang update in MapleStory, the Dark Lord's clone can be found in the Ellinia Magic Library. Players can battle the clone as part of a questline involving the Dark Lord.
How long does it take to be a cosmotlogist?
It typically takes around 9-12 months to complete a cosmetology program and obtain a license. Some programs may take longer depending on the individual's schedule and the specific requirements of the state licensing board.
No, stars are gaseous. More precisely, they are so hot that their matter is in a state known as "plasma".
How can a position time graph show if an object has constant acceleration?
In that case, the graph would be a straight line.
In that case, the graph would be a straight line.
In that case, the graph would be a straight line.
In that case, the graph would be a straight line.
What is the dark matter that all galaxies?
Dark matter is a mysterious, invisible substance that makes up about 27% of the universe's total mass-energy content. It does not emit, absorb, or reflect light, making it undetectable through traditional observation methods. Despite its presence being inferred through gravitational effects on visible matter like galaxies, its exact nature remains unknown.
What did the COBE satellite find that suggests that the big bang explosion occurred?
The CoBE (Cosmic Background Explorer) proved, beyond any doubt, that the spectrum of the CMBR is that of a black-body of temperature 2.7K -- some researchers were finding slight differences from this. The VERY minor anisotropies (about one part in 10,000) found in the CMBR are consistent with matter clumping in the early Universe, just enough to produce galaxies.
Note that WMAP and the Planck Probe have done even more precise measurements, and continued to get results consistent with CoBE.
Is a chain reaction possible in a substance that emit no neutrons when it fission?
No, a chain reaction is not possible in a substance that emits no neutrons when it undergoes fission. Neutrons are required to sustain a chain reaction by triggering the fission of other atoms in the substance. Without neutron production, the fission process cannot continue to release energy and sustain the chain reaction.
What are the three types of pressure that can push against the inward force of gravity?
The three types of pressure that can push against the inward force of gravity are thermal pressure (due to high temperatures), radiation pressure (from electromagnetic radiation), and degeneracy pressure (resulting from quantum effects in dense matter).
How can you find the number of neutrons an element t has?
One quick way to find that out is to open the Wikipedia and type "Isotopes of Carbon", "Isotopes of Uranium", or whatever element you are interested in. Please note that each element has several different isotopes; the number of neutrons varies from one isotope to another.
What is the charge of neutrons protrons electorns?
The charge of neutron is 0, as it is neutral.
The charge of proton is 1.6x 10 to the power -19 coulomb.
The charge of electron is -1.6x10 to the power -19 coulomb.
Cosmological effects refer to the influence of the large-scale structure and dynamics of the universe on astronomical observations. These effects include phenomena such as the redshift of light from distant galaxies, the cosmic microwave background radiation, and the expansion of the universe. Understanding these effects is crucial for interpreting observations and studying the evolution of the cosmos.
Has the universe been the same since the big bang?
No - That is a premise of the Steady State Theory. Rather the universe has been undergoing an evolutionary expansion in which the actual environmental state of the universe is ever changing. The interpretation of observational evidence from the detection of deep space radiations have provided us a window into the past; wherein the universe of the CMBR barrier demonstrates that the universe was once just a soup of hot dense plasma.

Was matter created by the big bang?
Some of the lighter material continued as clouds of gas that astronomers can still see through telescopes. Some matter, particularly heavier elements, also went into orbit around stars. Gradually these clouds in turn coalesced into orbiting bodies around their stars. The Earth, one of the gaseous bodies that had formed around our Sun, finally cooled enough to form a planet, and that was around 4.54 billion years ago.
Do atoms move between your bodies and other objects?
No, atoms typically remain within the bounds of objects. While some atoms can transfer between bodies through processes like breathing or consuming food, they do not freely move between objects without a specific mechanism for transfer.
How big was Pillotex before it went bankrupt?
Pillowtex led the industry in 1997 with sales of more than one billion dollars.
When neutrons electrons and protons leave the atom what happens to the charge on the atom?
If neutrons, electrons, and protons leave the atom, the charge on the atom will change based on the number of protons and electrons that have left. Protons and electrons have opposite charges, so if electrons leave, the atom becomes positively charged, and if protons leave, the atom becomes negatively charged. Neutrons do not affect the charge of the atom since they are neutral.
What is spectral distribution of cosmic microwave background radiation?
The spectral distribution of cosmic microwave background radiation follows a blackbody spectrum with a temperature of approximately 2.7 Kelvin. It peaks in the microwave region of the electromagnetic spectrum, with a characteristic wavelength of around 1 mm. This radiation is considered a key piece of evidence supporting the Big Bang theory.
If an objects velocity is doubled what happens to its inertia?
assuming its not starting at zero, if an object velocity is doubled, its kinetic energy (KE) is four times. If its trebled , its KE is nine times
equation : KE = (m*v^2)/2 joules
m=mass
v=velocity
