age of sun / universe?

Question

how do they know sun is so old ? universe is so old .

i read but i dun understand how is it accurate.. do they have a small star they can draw reference or confirm ?

i read that they measure the age of universe but looking at other gas forming a planet or stuff. i dun understand .. can anyone draw analogy or gives me example ? thanks

lol the reason why it is burning is already explain like long ago lolol

and btw , carbon dating is not used on the sun

how accurate ? can i at least say taht scientifically , the age of universe is no less den 1 million ?

Answer 1

By theory they observ the speed that a specific amount of gas and dust takes to form into a star, then they analyse the speed of mass being converted to radiation of different heights and types of stars, and by mathmatical calculations they mesure our suns' mass and compare to a nearby star and so they can estimate the age of our sun, which is approximatelly 5 billion years old.
The Universe's age is approximatelly 13.7 billion years old.
How did they mesure it?
By the Universe's expansion, we know that galaxies are moving away at a certain constant, but we do not know if the Universe's expansion is acelerated or constant, so astrophysics and cosmologists retroced back in time as a movie being watched backwards, so they estimate "everything" should of have been "together" at 13.7 billion years old at the precise momment of the Big Bang.

Answer 2

The Universe is about 3 times older than our Sun. The Sun is estimated to be about 4.5 to 5 billion years old, whereas the Universe is about 14 billion years old.

Answer 3

They don't. How could they. Carbon dating? Perhaps. But carbon dating is never accurate. They can date a rock using carbon dating one time and get a specif date, Then 3 years later if they go back and date that same exact rock again with the same method, The date will be different. How could they date the sun? How could we every get close to it, What do we date of it? Whats there to date when its fire. By using other stars?? Other planets?? But thats not the sun. Math and calculations of the universe cant be accurate since we don't understand the universe. Our minds cant hold with the understanding of the universe. And definitely not the sun. I mean what makes/ made it burn. Why is it burning. Whats the cause of the burning? Oh too keep us warm, But remember scientists say it happened by chance.

I would look to God. Or seek out Godly prevision. Lot wiser.

Answer 4

The sun is about 4-5 billion years old. The universe is roughly 15 billion years old.

Answer 5

dating stars is not very precise i think. models of stellar evolution show that as stars near the end of their life, they begin fusing heavier elements and expand (the giant phase). observation of luminosity and spectral color can then determine if this has happened or not, and gives a range of possible ages.

the nebular hypothesis suggests that the sun formed with the rest of the solar system. radiometric dating of meteorites have established the age of the solar system quite precisely (4.6 billion years ago).

the age of the universe is most precisely known from analysis of the cosmic background radiation measured by the WMAP satellite. it comes to about 13.7 billion years old, consistent with other estimates.

Answer 6

If you accept the big bang idea then the MW Milky Way galaxy is one of the bits from our LBB Local Big Bang. If there was one BB them probability is, that there were and will be many more BBs.
Thus the MW is decompressing from the very dense situation of the LBB. As the MW decompresses it starts giving off smaller particles from its core. Those particles are solar systems. They come from within the MW core because the material within the core is changing as the compressive forces lessen. Remember forces within a galactic core are on the mega atomic bomb scale. There are few or no electrons deep within galactic cores, They are huge configurations of protons and neutrons or even more elementary particles in collections that would have to be called totally ionized ions and that would be listed way off the bottom end of the periodic table. One day a collection of protons and neutrons goes through a change, process unknown but several different reasons are being argued, the change caused this collection to become less dense than the surrounding material. The less dense collection gets pushed towards the surface as the surrounding denser material squeezes in to take the collection’s place. It is quite a push, and coupled with the compressed mega atomic blast of the collections formation the collection heads toward the surface. The collection is decompressing as it rises to the surface. The huge proton and neutron ions break into smaller units as the repulsion forces of proton to proton are now stronger than the surrounding compression. As the collection passes through the upper layers of the MW core where there is a high concentration of electrons. The electrons react to the presence of the positive ions and rush to join up with every exposed proton. As the ions gain electrons their density lowers again. The bubble of the collection expands rapidly and all this time there is the push of the denser material from all around.

The collection emerges from the MW central core like a bubble breaking the surface of water. Two such emergences were recently noticed by southern astronomers. Southern, because south of earth is where the MW galactic core is. The report on Yahoo said the astronomers were really excited because the break-out speeds of the black hole like objects, were moving at just under the speed of light but slowing quickly due to the gravitational pull-back force of the MW galactic core. This would be the same as the "creation / birth" of the Sol Solar System. Things are still very active in the new solar system. The collection is now decompressing rapidly, bits and pieces break away from the central mass and everywhere changes are taking place as ions on all the surfaces break down into various smaller elements.

Sol Solar System SSS is as they say 4 to 6 billion years old. I might kick on an extra billion years to compensate for the time that the large ions broke down into the atoms the scientists use to determine the age of rocks.

Now watch this, As SSS left the MW core, it was released from the spinning motion of the MW core and preceded in a strait line out from the center, a radial vector as they say. SSS was not the first emergence and not the last. The location on the MW core where the first emergence occurred became a weak spot in the core and a location of much turbulence. These instabilities encouraged more collections to undergo a change like the first collection. Thus starts a string of changes and emergences from roughly the same location on the MW core. As each emergence occurred and the material sped off radially the MW core continued spinning. This is the cause of the shape of the spiral arms we see in many other galaxies.

Getting back to our SSS, the planets came from the main SSS collection as it exited the MW core. They are break off pieces of the original collection. Thus all the planets and the sun are made up of the same type of material, just broken down in a variety of variations. What we see today is the results of those billions of years of breaking apart.

The sun, which has most of the material of the original collection, and all of the planets are still undergoing decompression. Large ions deep within the sun and the planets are still collecting up electrons and breaking down into smaller ions and eventually into atoms. Atoms are much more stable than the large ions because there are fewer protons in close proximity to each other and the protons reach an equilibrium point where they have enough room for themselves and the attraction between the protons and neutrons and the repulsion of proton and proton are more in harmony. We still see breakdowns, as in uranium atoms, but this is nothing compared to what is going on with the large ions deep under our feet and inside the sun.

Oh, by the way, the sun is not a big ball of hydrogen forming into helium. That never did make any sense. The sun is decompressing like the rest of the material in our local part of the universe. The center of the sun is huge ions of protons and neutrons with higher percentage of neutrons toward the center. The sun does have a huge collection of electrons covering its skin and these electrons tear up the atoms on the surface so that the surface also has a large proportion of loose protons. Thus lots of electrons and loose protons looks like hydrogen from earth. Early spectrographs of the sun only noticed the hydrogen so the scientists went off to their corners and tried to figure out how something as huge as the sun could be made only of hydrogen.
They worked hard to come up with the wrong answer and are hard pressed to let go and take another look.
Here on earth things are on a much smaller scale and decompression happens much faster when the main object is small. At the center of earth there are still quite a few large completely ionized ions, as we head out from earths center a few electrons are found wandering between ions. Progressively more and more electrons are found with the atoms as we head out toward our surface. The ions have decompressed to what we see on the bottom row of the periodic table. There are many more electrons available toward the surface, so many so that they form a river like flow of electrons known as the Van Allen belts. The electrons race around the earth from poll to pole waiting for their chance for a date with a proton.

Now here we are on earths surface. Ions have become atoms, atoms have formed into molecules as earth’s surface decompression allowed. The molecular chains became longer and longer as time went by and some where along the way thousands of different molecules were under conditions that allowed them to reproduce. Oops, life on earth. And away they go. Combinations and combinations and several mass extinctions later, here we people are. All Earth Life Forms; yes, you are an ELF
.
There are several extrapolations of this story I have skipped over, but I am making a book out of it all so perhaps you can read more later.

One extrapolation I will tease you with is: The best place to look for ET is the next few stars further out along our arm of the MW and the next few stars closer in along our arm of the MW.

Another bit I can not leave without saying is. When we left the MW core did we have escape velocity, so that we will continue outward bound, or did we not have escape velocity and thus will reach a high point as a solar system then start heading back into the center of the MW?

Good bye for now. Hidden in this story is the explanation of gravity. Did you notice?
