Cosmology

BIG Bang is a hypothesis and on the basis of cern research big bang theory was proposed.

Our solar system is thought to reach out as far as 50,000 AU, where 1 AU is the Earth to sun distance. This it about the limit of the suns gravitational effect. This gives the solar system a diameter of around 100,000 AU.

Fusion could occur with two deuterium nuclei, or one deuterium and one tritium. Helium would be formed in both cases, but does not take part in the fusion itself.

The most likely reaction of deuterium and helium would be:

D + He --> LiM --> D + D + D

The "M" superscript indicates an excited metastable nucleus that instantly breaks apart.

Another reaction is similarly likely:

D + He --> LiM --> D + He

Either way you are making no progress with fusion, the net reaction(s) probably even consumes energy instead of releasing it (my references don't supply energy figures for these reactions). Also such reactions would require higher temperature and pressure than DD or DT fusion do.

Note: deuterium/helium-3 fusion does work and releases energy (at higher temperature and pressure than DD or DT fusion) but only produces helium and neutrons. Helium-3 is also rare.

In practice, the original answer is absolutely right. However the above reactions will happen under conditions of temperature and pressure that permit D/He fusion, but as I already said they get nowhere, they are dead end reactions.

I dont know correctly but it may be most of the galaxy I think so!

In reality we don't 'know' but our best understanding is;

Ordinary matter: ~4.5 %, dark matter: 23%, dark energy: 72%.

Reputedly 80% of this 23% dark matter is cold dark matter and 20% is hot dark matter.

It has been said that "dark matter.... makes up more than 80% of the matter of the universe." but that is a common misunderstanding; But we MAY say; up to 96% of the mass-energy in the universe is 'dark'.

We don't know what dark matter is, but in fact it only means it does not have an easily detectable 'electromagnetic cross section' so it could be electrons/ions plasma, which has a refractive index of 1.

The Big Bang expresses the understanding of an evolving universe from a one dimensional singularity to the traditional fourth dimensional model of our ever-accelerating universe. In general, existence came into being upon the dimensional unfolding of Space and Time from the condition of a singularity (formed during a degree of convergence in Space and Time) into the reality of our traditional fourth dimensional SpaceTime continuum. The Big Bang is more a reference to an unfolding evolutionary model of existence in which SpaceTime allows for the integration of positive matter (or an explosion of multiple dimensions from a more singular dimensional containment; i.e. singularity). The concept of this singularity provides for a temporal confinement in the unification of all the primary forces of the physics (i.e., gravitational, electromagnetic, strong and weak). Immediately after this creation event, the evolutionary expansion of the primary quantum forces provide for a dense and hot plasma soup which expands to permeate its unfolding dimensional containment. The universe continued to decrease in density and fall in temperature, hence the typical energy of each particle was decreasing. Over a long period of time, the slightly denser regions of the nearly uniformly distributed matter gravitationally attracted nearby matter and thus grew even denser, forming the four possible types of matter are known as cold dark matter, warm dark matter, hot dark matter, and baryonic matter. Eventually gas clouds, stars, galaxies, and the other astronomical structures we observe today, began to precipitate in the expanse of the expanding universe. Note: The details of this process depend on the model used, and the amount and type of matter, and localized quantum instabilities present to facilitate the accretion of positive mass density in the Universe.

Different atoms have a different number of electrons. This is why they show different spectra.

The most matter in the universe is the proton called Amanda Yorch. This proton has 395000 neutrons and electrons. The sun is also named after Amanda Yorch.

A black hole doesn't cause anything. It is a gravity trap - a place where gravity has gotten so strong nothing can escape (excluding Hawking radiation at the event horizon.) What happens is a star (or stars) is (are) so heavy after burning much of their hydrogen into helium that the star(s) start to collapse in on itself. If there is a certain amount of mass at a certain distance (critical mass) then even light can't escape the gravitational pull and now it is a black hole. Because energy can't just disappear and Hawking radiation exists, after enough time a black hole can expend itself - burned so much matter to energy that it 'dies' - that is it expends the last of it's energy in a humongous burst of radiation - an explosion of light if you will and all that's left are those echoes of it's death.

"Dark Matter" is currently only a mathematical concept, a "fudge factor" thrown into some calculations to make the numbers work out. We have no idea if "dark matter" really exists, how it would affect the universe, or how it might be detected or manipulated. It's all guesswork, and all the scientists have conflicting guesses.

For myself, I suspect that there are some fundamental things that our theories do not yet understand, and that in the future, we'll discover that "dark matter" will prove to be nothing at all.

CERN is an organisational headquaters of scientists, based in Switzerland, which houses a large hadron collider (the LHC). By smashing particles together at great speed, it's hoped that the LHC will be able to recreate the conditions present at the beginning of the universe (the big bang). The scientists are examining the microscopic collisions, which are created by shooting atoms around the huge tunnels of the LHC.

It's very possible that humans will no longer exist - or exist as humans - in that amount of time. In fact, the Earth, the primary home of humans, may not exist. Of course, humans may colonize other spheres.

Humanity may split into two sub-species in 100,000 years' time as predicted by HG Wells, an expert has said. Evolutionary theorist Oliver Curry of the London School of Economics expects a genetic upper class and a dim-witted underclass to emerge. The human race would peak in the year 3000, he said - before a decline due to dependence on technology. People would become choosier about their sexual partners, causing humanity to divide into sub-species, he added. The descendants of the genetic upper class would be tall, slim, healthy, attractive, intelligent, and creative and a far cry from the "underclass" humans who would have evolved into dim-witted, ugly, squat goblin-like creatures.

Race 'ironed out'

But in the nearer future, humans will evolve in 1,000 years into giants between 6ft and 7ft tall, he predicts, while life-spans will have extended to 120 years, Dr Curry claims.

Physical appearance, driven by indicators of health, youth and fertility, will improve, he says, while men will exhibit symmetrical facial features, look athletic, and have squarer jaws, deeper voices and bigger penises. Women, on the other hand, will develop lighter, smooth, hairless skin, large clear eyes, pert breasts, glossy hair, and even features, he adds. Racial differences will be ironed out by interbreeding, producing a uniform race of coffee-coloured people.

However, Dr Curry warns, in 10,000 years time humans may have paid a genetic price for relying on technology. Spoiled by gadgets designed to meet their every need, they could come to resemble domesticated animals.

Receding chins

Social skills, such as communicating and interacting with others, could be lost, along with emotions such as love, sympathy, trust and respect. People would become less able to care for others, or perform in teams.

Physically, they would start to appear more juvenile. Chins would recede, as a result of having to chew less on processed food.

There could also be health problems caused by reliance on medicine, resulting in weak immune systems. Preventing deaths would also help to preserve the genetic defects that cause cancer.

Further into the future, sexual selection - being choosy about one's partner - was likely to create more and more genetic inequality, said Dr Curry.

The logical outcome would be two sub-species, "gracile" and "robust" humans similar to the Eloi and Morlocks foretold by HG Wells in his 1895 novel The Time Machine.

"While science and technology have the potential to create an ideal habitat for humanity over the next millennium, there is a possibility of a monumental genetic hangover over the subsequent millennia due to an over-reliance on technology reducing our natural capacity to resist disease, or our evolved ability to get along with each other, said Dr Curry.

A weight pan is used in physics experiments to hold known masses or objects so that the effects of gravity and weight can be measured. By adding masses to the weight pan, students can investigate how different factors, such as force and acceleration, affect the motion and equilibrium of the system being studied.

So the Anunnaki are myths but everything in the bible is real....the Anunnaki were not myths they were part of the Sumerians written history which most of the old testament is vague rearranged borrowed stories from the Sumerians.

Something like 14 billion light years.

That's a great distance compared to the length of my kitchen. But we

don't know how big it is compared to the size of the whole universe,

because we don't know how much farther past that the universe extends.

No. More accurately, nothing in the universe is stationary. There is no single fixed reference point in the expanding universe, and all known astronomical objects are in motion with respect to one another.

The Sun is indeed continuously releasing a vast amount of energy, because of nuclear processes taking place in its core. You could calculate how much mass is being lost by being converted to energy using Einstein's famous matter-energy equivalence formula, E=mc^2. The Sun is also losing small amounts of mass constantly by ejecting high energy particles, and also shedding some of its outer envelope into space through thermal and magnetic effects.

That means that the Universe expands faster and faster. It causes the Universe to grow, and the general density of matter in the Universe to decrease over time.

Aquarius era is the time period that man takes into account the concept of thinking of others and not himself. In other words, it us the time for huminity . helping, belueving and loving our fellow man. It was during the sixties that we had the pharse, love one another, make love not war and so on... But like most loving cocepts it was all taken out of the true meaning and society cause the positive concept to become a negitive life style. So, Aquarius era is just a beautiful state of taking a loving approach to the way we live. "Loving one another and practicing what we say"

Not at the present time, just like scientists haven't yet figured out why there is lightning in our skies. The idea that our Universe has been expanding at a (more or less) steady rate for the last 13.7 billion years, is just as proven as the idea that our Earth goes around our Sun. However, as Alan Guth said so well: "The Big Bang theory says nothing about what banged, why it banged, or what happened before it banged."

Quasars have all kinds of spectral lines namely more energetic ones which makes them the brightest objects in the night sky.

You might confuse Antares with Mars, since (a) it is red, (b) it is bright, and (c) it is near the Ecliptic.

Far denser -- almost infinitely more dense -- than it is today.

It is a mistake to say that the BB claims that our entire Universe was once the size of a proton. That statement only applies to what is now the VISIBLE universe -- that small sub-set of our Universe that we can now see. While this 93 billion light year diameter ball is pretty large, it is impossible to determine how much more of our Universe is out there, beyond our present ability to see -- the total amount could be infinite. Thus, instead of saying our entire Universe was much SMALLER than it is today, it is more correct to say it was much DENSER.

Actually it isn't. Or at least, not everybody is convinced. It has several large loopholes; for example:* The cosmological argument assumes that everything must have a cause; therefore, it says, the Universe must have a cause. But if you assume that there is a God who created the Universe, this God (applying the same argument) must itself have a cause.

* Even if we assume that something created the Universe, the cosmological argument doesn't allow you to make any conclusions about the identity of the creator... or creators. There might be a single God, many gods, or we might (for example) be part of a computer simulation on a "higher level"; and the "cause" might not even be an intelligent being, but random chance.

It is called the celestial sphere and it has coordinates like latitude and longitude. The simplest coordinates are elevation and azimuth, and there is another popular tilted coordinated system with its polar axis parallel to the Earth's axis. In this system the coordinates are the declination and the hour-angle.

A fixed star keeps the same declination all the time and its hour-angle advances by 360 degrees every 23hr 56 min as the Earth rotates on its axis.
