i dont think this is true , because at the beginning earth was a really really hot place with lave flowing all over the place , and it was constantly being hit by meteorites and other rocks from space . so how can water exist in such situation ?Apparently water existed on Earth since its formation
Bad choice of words..theories are facts...hypothesis are not facts.24) Big Bang is a fact.
We know for sure that universe is expanding and that 13.7 billion years ago it was very hot and dense. But still it does not prove a Bing Bang. Big Bang theory does not work without inflation theory and in order to prove inflation we need to register gravity waves from it. Best way is to detect polarization of CMB by gravity waves. So far it was not detected thus Big Bang remains a theory.
25) Known universe started from the Big Bang.
According to current model, first was a "cold" Inflation stage expansion and only after that inflation field energy transformed into matter and heat, making it super dense and super hot, creating a Big Bang.
This misconception we can see in popular shows for example "How the universe works":
How the Universe Works S03E04 First Second HDTV XviD-AFG - Vidto (what they say from 10:46 is WRONG)
Meteorites are not a problem for water, they did actually bring some water with them, but small portion compare to total.i dont think this is true , because at the beginning earth was a really really hot place with lave flowing all over the place , and it was constantly being hit by meteorites and other rocks from space . so how can water exist in such situation ?
i have heard that nutrinos are very difficult to intercept ,they can pass through 1000s of kms of iron sheet
No, theory is not a fact. Theory is well developed hypothesis.Bad choice of words..theories are facts...hypothesis are not facts.
1) There is no place where the big bang occurred, or more correctly it occurred everywhere. Imagine infinite super dense universe that started to expand and turn into less and less dense. Thats the big bang.right now we dont have any better way to explain the beginning of universe than the big bang . the oldest light that we can see in space , we assume that is where big bang occured. beyond which we cannot see .

Its not a hypothesis like the bing bang, IT IS the bing bang.that is just a hypothesis just like the big bang
No thats very wrong concept of the big bang. Universe is same in all directions. That would not happen in case of expansion from one point.but expanding from a point(source of all the materials) seems more likely than expanding from everywhere .
I thought fact means data in science...Theory is the highest form of knowledge...the heliocentric theory...germ theory of disease...theory of evolution...I have never seen anything termed as fact in science.Meteorites are not a problem for water, they did actually bring some water with them, but small portion compare to total.

2) The oldest light we can see comes from 380 thousand years after the Big Bang.
Are you stating study state model? than you are wrong, study state model proves false by scientists, if we look further into the Universe, The Universe apears different from different anglesNo thats very wrong concept of the big bang. Universe is same in all directions. That would not happen in case of expansion from one point.
their is a controversy between scientists Cosmos is either finite or infiniteBig bang is expansion of infinite universe.
Many things can be called facts:I thought fact means data in science...Theory is the highest form of knowledge...the heliocentric theory...germ theory of disease...theory of evolution...I have never seen anything termed as fact in science.

I wrote the same earlier here. But for sake of simplicity u can consider it a infinite. We dont see any border effects so technically its infinite.their is a controversy between scientists Cosmos is either finite or infinite
No Sir Universe isn't same in all directions its a. Universal fact that most scientists believeMany things can be called facts:
That Sun is about 150 mln kms from earth, that Sun is about 333 K times heavier than Earth, that Sun consists mainly from H and He etc etc..
As for theory, theory became solid when it is confirmed by many tests. For example relativistic theory confirmed by swarms of tests. As for big bang we still dont have a solid confirmation of inflation theory.
No its same from all directions.

fact is a misleading term... theory is an widely accepted model that confirms to past and current observations about the universe and might even make predictions that upon observation seem to match...I thought fact means data in science...Theory is the highest form of knowledge...the heliocentric theory...germ theory of disease...theory of evolution...I have never seen anything termed as fact in science.
