Thread: Big Bang theory?

technically, it wasnt a molecule, but just a single point that was super dense and super heated. That is what supposedly exploded.

But, there could have been more than one of theses singularities too...but I find it more likely that multiple singularity explosions all contributed to our universe. Unless they were so far awart that we havnt observed one that overlaps the other yet

Also, wouldn't be extremly dangerous if another one of these exploded?

Well, the thing about the big bang is its a theory, and like every other one it has holes. Its the best one out right now, but I try not to think in a linear sense. Unfortunately its next to impossible to recreate it exactly as it would have happened right now. Basically we are able to measure the velocity of the expansion of the universe, and work back in time. This brings us back to a point when seemingly everything was collapsed in on itself on an incredibly small scale. We just cant go back further, quite frankly we don't have the technology to measure energy/mass at that scale and we're unable to get.. 'before' the bang. I'm not a scientist all I know is this is where they are stuck. The numbers collapse.

The entire universe spontaneously appearing out of nothing at the rate it did is pretty much impossible, so we know something caused it.

We know something banged, we don't know what or why it did so. All we know is everything was incredible dense, small and hot. It then expanded at an incredible accelerating rate outwards, and here we are.



I mean honestly I doubt the universe is as small as we think it is.. even though we know its huge. I mean you've just got to think of things on different scales. As far fetched or 'hippy like' as it may sound how do we know what we call the entire universe isn't just a fraction of a molecule on the 'real universes' scale. Like we make up a pixel in billions of light years. What if its the opposite? What if theres intelligent life 1/1,000,000,000,000,000,000,000,000,000 the size of an atom? We are only 'big' because we think we are. Why are we the magic size, its kind of naive to think in that sense when you consider how big we already know the universe to be. If you were to measure the size of a human brain compared to the size of the universe as we know it, I'm sure you would see what Im getting at. And at the moment.. we're kind of at the top of the line intelligence wise. I honestly doubt thats true, but theres nothing to prove otherwise atm.

Im not saying that you should think that.. just prove me wrong. We dont have the technology to do so today. We used to think the atom was the smallest thing, we know thats not even close to true now.. how small do you think we can go? How big do you KNOW we can go?

One day we will find the answers, I wish I could answer you better.. But yeah another 'big bang' would most defiantly be devastating. I mean maybe our entire universe will explode and cause a bang trillions of times bigger and more powerful to create a new universe. And eventually if/when 'they' (The new intelligent life) looks back on what caused the universe they see a big bang on whats seemingly a tiny dense spot.. which was really the entire universe as we know it! Dun dun dun.. except not really.. But who knows.. maybe we already are those people.. the third time around?

What if the next one of those things that is going to explode is under your bed?

Holy Hannah batman.. get the utility belt!

If you sleep on a couch in the Andromeda galaxy, you will have at least another 200,000,000 years of safety.

Oooh... I have something for you.

With some cool music, too!

And another one... Just don't start some kind of flame war just because it mentions a 'creator', mmkayy? I didn't like it, but I ignored it.

We are very, very small...

That was a GREAT find! Only problem with it is the misspelling of "Irak"

Planet earth is a micro dot on a micro dot on a micro speck in a micro section, somewhere in the incomprehensible infinity of the universe.

And the Big Bang Theory States that the Universe Originated from a single point in space, but doe snot, however, address the actual point, just the expansion.

I think what everyone is ignoring is that the Big Bang theory does not suggest that everything originated from a single point in space, but that space and time themselves were once as small as we are capaple of measuring (planck length), if the idea of measurement even makes sense in such a context. Space time is expanding, matter and energy are not; this is what the big bang theory postulates.

Anteres is small compared to the biggest known star, i forget the name. Imagine when that star becomes invisible.

Correction:

Dopey internet info, apparently. Sorry about the bad news.

It's said that after trillions of years when the universe dies, a new one could bud off of it. I don't know the exact physics of it, but of course you would have to think that the universe is ever expanding and won't die in some Big Crunch like event.

VY Canis Majoris?

http://www.dreamviews.com/community/...ad.php?t=52894

Oh ****.

That's huge!

Aw in your first post where the pics of the blue and red supergiants? Those are the real kickers. I swear a red supergiant is gonna eat us someday

edit: Oh fuck that's a big star, XY Canis Majoris. Oh fuckin' hell.

ok, XY Canis Majoris is gonna eat us someday.

Hahaha that could be funny taken the wrong way

It's huge it's probably really hot too.

But if time and space were that small, but all matter and energy was still the same, isn't that still the same as originating from a single point?

Yeah probably. I forgot the name. I wonder if there is a unknown star to us that makes VY Canis dissapear off scale, and another one that makes that one dissapear. You would be thinking if everything else is always gonna get bigger and bigger and wonder what the biggest star is. Now what is the biggest known planet?

I thought that was VV Cephei A. Here is the video your picture is from, I think...

http://youtube.com/watch?v=HKPUYZZbWxs

Since that video was made, a larger star was discovered. It is called A1. Both stars are in our galaxy.

EDIT: It looks like Canis Majoris was discovered to be larger than VV Cehphei A, but the jury is still out on A1. Very confusing.

similar, but far from the same. We understand the expansion of energy and of matter. We do not have a firm grasp on the cause or mechanism for the expansion of empty space time itself. Also, one can not accurately refer to before the big bang when time itself remains inside of the object of investigation. There is no before outside of what is included in the big bang and there is no outside either, as far as we know.

I think TrES4 subclassed "Puffy Planets" discovered in 2007 is currently the largest known planet which is about 1.7 times the size of Jupiter. Scientist says that TrES4 is way bigger than it supposed to be considering it's mass. Basically it should be the size of Jupiter but it's twice as large.

TrES4 appears to be something of a theoretical problem.

The parent star of TrES-4 is also unusual in that it is about the same age as our sun but much farther along in its evolutionary history. Because it is more massive, it has evolved much faster, It has become what astronomers call a subgiant, or a star that has exhausted all of its hydrogen fuel in the core and is on its way to becoming a red giant.

Our sun is not expected to become a red giant for another 5 to 7 billion years. When it does, the sun will expand to engulf the inner planets and possibly Earth. Because TrES-4 orbits so close to its star, it is certain to be consumed once the star becomes a red giant in about a billion years

OP; we observe via various methods that galaxies are flying away from each other (for example, red shift).

The inescapable conclusion we must make, extrapolating backwards through time, is that all of the matter in the universe must have once occupied a single point.

That's all the Big Bang hypothesis is. There's no such thing as a 'universe particle' floating through space which is liable to explode.
