Big Bang Theory and Sinhala Buddhist explanation about Big Bang Theory

INFLATION

In a big bang without inflation,what are now widely spaced regions of the universe could never have become so similar in density and temperature.inflation theory proposes that our observable Universe derived from a tiny homogeneous patch of the original Universe.The effect of inflation is like expanding a wrinkled sphere-after the expansion,it's surface appers smooth and flat.

Sinhala Buddhist explanation about Big Bang Theory!!!!

Machan i wonna ask you that lord Buddha ever explained the formation of universe.

I think the lord Buddha said "Siyalu sanskarayo Anithayi"
lord Buddha said there is no end or beginning for the "time"
If there is a beginning for the time then there is beginning for a universe.When ever there is no beginning or an end for the time then there is no beginning or an end for the universe.

What is the beginning of the universe? then we explain it was created by "this and that"(may be matter and energy)
How those "this and that" created in the first place?
no answer.
that's why there is no beginning for the time <--->hence no beginning for the universe

lord buddha has talk about the formation of the universe. I'll give some sources, But can't remember all of them. Agganchcha Suthra, Anguththara nikaya. They talk about how the universe is foarmed and how the life is created. In these suthras' lord buddha has once sayed that physical things existing in the universe are rotating around another. And lord buddha has talked about planets, and their motion. the time take for a compleate motion. and how planets get together to from a solar system, and the solar system's motion. again the time taken by the solar system to compleate a motion cycle. and how solar systems get toghter to form a galaxy, how clusters of galaxies are formed. how they move, what type of motion they have...... it continues.

after explaining a certain time frame taken by a cluster of galaxys (it is hard to explain it, they are called sahassi loka dhathu, dwi sahassi loka dathu etc, it shows how each units get larger and different, like solar system to galaxy. ) to complete a motion cycle of its orbit, lord buddha once used that mesurement of time to explain the time difference between the appearence of two buddhas on the planet.

anyone can visit a temple and ask for above mentioned books and read those thngs. Those books are very rare and now hard to find. people little by little forgeting those parts of the buddhism. I think.

lord buddha said that there are things which will not be captured by a normal human imagination. (achinthya wishaya, chinthya wishaya) and they are ,

the very begining of the universe, materials.
a mind of a lord buddha

(there was few more, but I cant remember others)

achinthya things are unable to captured by the normal human imagination. which means they exist beyond the limit of our vision,senses,imagination. and those things can be understood by a lord buddha. leading the mind to understand them can cause problems inside the human.

big bang theory is TRUE! one day they would realize that Darwins theory is WONG too..

i bought a book from Meegamuwa in 2003 regarding the comparisons between Darwin's theory of relativity and Lord Buddhas explaination of creation. Sadly, because i'm currently in Sri Lanka, i cannot look for the book in my home. but i suggest that you try to find the book and read it. it is very informative.

MAchan procedure is much better than the wrd "formation" cz theres some flow of occasions neda machan??

anyone can visit a temple and ask for above mentioned books and read those thngs. Those books are very rare and now hard to find. people little by little forgeting those parts of the buddhism. I think.

Yes machan its very hard to find if u managed u have to learn Sinhala for many yrs to undstand the language of them neda??

Hmm mabayi machan does it so important??
Meka amataka kala kiyala machan echchara avulak na neda ???
Mokakda meken apiata nivan magata ganna puluvan adarshe???

Graphical timeline of the Big Bang

This timeline of the Big Bang shows the sequence of events as predicted by the Big Bang theory, from the beginning of time to the end of the Dark Ages.

It is a logarithmic scale that shows 10 * log10 second instead of second. For example, one microsecond is 10 * log100.000001 = 10 * ( − 6) = − 60. To convert -30 read on the scale to second calculate 10 − 30 / 10 = 10 − 3 = 0.001 second = one millisecond. On a logarithmic time scale a step lasts ten times longer than the previous step.

Why is the Universe flat and not spherical?
​

My question involves the Universe is flat theory. If there was a big bang why would the Universe be flat? I would think that the Big Bang would result in a sphere shape mass of energy, light, matter, heat, radiation, etc. and whatever else expanding outward while maintaining the shape of the sphere.

The meaning of the Big Bang has been very often misunderstood. It is thought that something exploded somewhere and then the exploded part expanded to where we are currently. This is not correct. Before the Big Bang, there was no space or time. So, there is nothing "outside" the Big Bang. The Universe simply expanded from a very small volume into a huge volume, and this expansion is occuring even today. So, the place where we are right now corresponds to some place in a very small volume in the very early Universe. Hence, the Big Bang occured EVERYWHERE in the Universe. It occured at all places including the place where we are right now.

Why does the Universe look flat? This was one of the perplexing questions in cosmology for a long time. Today, most astronomers believe in the theory of inflation (and there are pieces of evidence supporting this). According to this theory, the Universe underwent exponential expansion about 10-30 seconds after the Big Bang. The result was that something of the size of an atom expanded to the size of the solar system by the end of the inflationary epoch.

If this were the case, irrespective of the original geometry of the Universe, it would appear flat to us. The analogy will be to take a balloon; we can easily see it to be rounded; now blow the balloon to a very large volume and then put a small ant on its surface. The ant will think that it is on a sheet; it cannot detect the curvature. To put this in another way, the distances that we probe are way too small to detect any possible curvature in the Universe.

If as you say "the distances that we probe are way too small to detect any possible curvature in the Universe" ... how can we accept recent "proofs" of a flat universe? Are all attempts to prove the flatness or otherwise of the universe limited to data collected from the observable universe? If so, and we suppose our view to be equivalent that of a short sighted ant on earth, surely it must be an impossibility to find such a proof, unless of course information can travel faster than light.

First, you have to distinguish between "universe" and "observable universe". Technically, "universe" constitutes everything that exists, while "observable universe" constitutes everything that exists within our horizon (that is, the volume of the universe within which light has had time to reach us). Every observation we can ever make is confined to the observable universe, and we have no way of knowing for sure what's happening beyond the horizon. But many people use "universe" as shorthand for "observable universe", which can create some confusion. So when we say "WMAP provides strong evidence that the universe is flat", we really mean "WMAP provides strong evidence that the observable universe is flat".

However, according to inflationary theory, even if the universe has some curvature, the observable universe should be flat at the level at which we're capable of measuring it. But we don't *know* that inflationary theory is correct. So yes, it is important to do experiments like the one performed by WMAP. If we were to detect deviations from flatness in the observable universe, then it would provide evidence against inflation.

Machan in science there are no absolute truth and the truth revealed by science can be change at any moment cz of other invenstions
Neda machan??

Even in the pst ppl believed that sun goes around the earth
that viewpoint lasted for centures ne

How can the universe be "flat"? We're 3D!


1. You say the that the observational universe is flat how can this be if we live in 3D?

2. I cannot wrap my brain around the meaning of a FLAT universe. I've read hundreds of definitions on the thing and cannot make sense from it. The ant on the balloon does not make sense to me because there is space above and below the ant on the surface of the balloon. If the universe is physically flat, then what is above and below it? I have tried and tried to understand what 'flatness' means but it never makes sense. Space and the things in it are found in every direction so how is the universe flat? Is it flat like a coin or a tyre or flat like a sheet of atoms? Does it actually just mean that if the universe was filled with adjacent cubes, all the corner angles of all the cubes would equal 90degrees? or something like that?

It's great when our readers answer their own questions! #2 is totally correct - when we say the universe is flat it is not in the same sense that a piece of paper is flat, but rather means that the geometry of the universe is such that parallel lines will never cross, the angles in a triangle will always add up to 180 degress, and the corners of cubes will always make right angles. We call this kind of geometry (the kind you learned in school) Euclidean geometry.

It's easy to make examples in 2D space (ie. a flat piece of paper vs. a curved piece of paper, or the surface of a balloon). It's not so easy to illustrate flat 3D space - since we are 3D! So it's totally understandable that the concept is confusing

This is refering to the theory that the whole universe is flat. I believe that the universe as a whole likely has some three-dimentionality to it, but I'm curious as to why it is that asteroid belts, the milky way, and even the planets in our solar system all seem to be flat and fall in line with one another. For instance why isn't mars above us, and why is it that all the planets seem to be spaced out and lined up.



The orbits of the planets and the shapes of spiral galaxies has to do with the way they form and conservation of angular momentum, and nothing to do with the geometry of the universe as a whole. As the solar system formed from a giant spherical gas cloud, the cloud started to rotate. That meant that it was easier for material to fall in along the poles than around the 'equator', because around the equator it had to battle against the centripetal acceleration trying to push it out again. The cloud therefore slowly collapsed into a disk like structure from which the planets formed. The same exact process explains the disks of spiral galaxies.​

Underlying assumptions
​

The Big Bang theory depends on two major assumptions: the universality of physical laws, and the Cosmological Principle. The cosmological principle states that on large scales the universe is homogeneous and isotropic.

These ideas were initially taken as postulates, but today there are efforts to test each of them. For example, the first assumption has been tested by observations showing that largest possible deviation of the fine structure constant over much of the age of the universe is of order 10−5. Also, General Relativity has passed stringent tests on the scale of the solar system and binary stars while extrapolation to cosmological scales has been validated by the empirical successes of various aspects of the Big Bang theory.

If the large-scale universe appears isotropic as viewed from Earth, the cosmological principle can be derived from the simpler Copernican Principle, which states that there is no preferred (or special) observer or vantage point. To this end, the cosmological principle has been confirmed to a level of 10−5 via observations of the CMB.] The universe has been measured to be homogeneous on the largest scales at the 10% level.​

FLRW metric​

General relativity describes spacetime by a metric, which determines the distances that separate nearby points. The points, which can be galaxies, stars, or other objects, themselves are specified using a coordinate chart or "grid" that is laid down over all spacetime. The cosmological principle implies that the metric should be homogeneous and isotropic on large scales, which uniquely singles out the Friedmann-Lemaître-Robertson-Walker metric (FLRW metric). This metric contains a scale factor, which describes how the size of the universe changes with time. This enables a convenient choice of a coordinate system to be made, called comoving coordinates. In this coordinate system, the grid expands along with the universe, and objects that are moving only due to the expansion of the universe remain at fixed points on the grid. While their coordinate distance (comoving distance) remains constant, the physical distance between two such comoving points expands proportionally with the scale factor of the universe.

The Big Bang is not an explosion of matter moving outward to fill an empty universe. Instead, space itself expands with time everywhere and increases the physical distance between two comoving points. Because the FLRW metric assumes a uniform distribution of mass and energy, it applies to our universe only on large scales—local concentrations of matter such as our galaxy are gravitationally bound and as such do not experience the large-scale expansion of space.
