Thread: Is the Big Bang theory scientifically falsifiable?

The question is not meant as an attack on the scientific method, or science in general. The scientific method of empirical observation and verification has more than proven its worth in discovering, explaining, and defining an innumerable number of natural phenomena and processes, as opposed to faith which takes much of the universe as it was, is, and will be for granted (not to mention the unverifiable claims of many religions, including the existence of a God).

There is much empirical evidence which suggests or implies the viability of the Big Bang theory as a model to explain various indisputable natural phenomena (such as the cosmic background radiation and the fact that the universe is expanding). It seems, however, that science oversteps its bounds when it attempts to explain the origin of those phenomena (i.e. the Big Bang model).

Are there any experiments that could be devised, or is there any practical way, to disprove the Big Bang theory?

If there is such an experiment, and that experiment can conform to the scientific method of observation and verification, than the Big Bang theory can be considered a scientifically valid theory of the origins of the universe.

If there is not, than the theory actually shares something in common with faith by way of its failure to meet the criteria of falsifiability (just as the existence of an omnipotent God cannot be proven through experimentation to be false, and is therefore an unscientific claim, so the Big Bang theory would equally fail to be falsifiable and scientific).

What do you think? Is such an experiment possible?

Probably not, at least not at the level of present understanding.

You mention the Big Bang as a way of explaining background radiation. I thought it was the other way around, and I could very well be mistaken, but my understanding is that the Big Bang theory predicted background radiation before it was discovered. Or was background radiation one of the clues that pointed to the Big Bang?

I'll go ask google.

But you do pose an interesting question.

Here is a good article on the subject:

WMAP Big Bang CMB Test

So Big Bang theory did predict cosmic background radiation some 17 years before the radiation was discovered.

Currently there is no way to prove or disprove any theory of such breadth and magnitude. What can be proven--as the phenomena can now easily be seen and measured with powerful instruments that were not technologically possible even a decade ago--or at least demonstrated, is that the universe is a place where explosions are quite common. We can now see and measure these very distant explosions which could only be theorized about before, but we we now are seeing is supporting the authenticity of theories made long before any sort of reasonable experiment could be undertaken--which I'm certain made all supporters of the so-called "big bang theory" very happy.

Seeing is believing, but now we realize that there are many things in the universe, in addition to all the lovely explosions, which we still cannot see. Therefore I imagine that over time the "big bang" theory will, like Newton's useful and yet ultimately incomplete theories, sort of fall by the wayside as new forces in the universe are discovered. As an explanation of "something that happens a lot in the universe" the big bang theory is quite sound.

As an explanation of "how the universe got to be here", however--it's not so sound. As we witness the universe around us, we are as astonished and frightened by its crawling chaos and brutal violence as we are by its inexplicable symmetry, and a logical person starts to realize that the explanation for all that... stuff is probably not quite so simple.

There's no scientific way to "disprove" the theory. Human beings tend to invest belief in this theory because there's something that appeals to them about it; it's an appealing idea, and that some evidence can be found in scientific research to support it is delightful to the average human, who feels somewhat uncomfortable at the notion of things that have no recognizable beginning or end.

I'm sure God will be humored to to know His existence rests upon His falsifiableness, Edge.

What the hell happened to good Jewish boys? We're going to have to send you back off to synagogue. I can just see you getting into heaven and Moses in the form of a white bearded Charles Heston clocks you across the head with that long staff of his.

But this is an interesting question you pose.

To be honest with you I'm not certain (meaning I'm not able to comprehend it entirely yet) science need depend on the criteria of falsifiability as opposed to the concept all natural phenomena needs to be verifiable.

Science often works with theories it does not fully grasp yet but over time through accumulation of information and evidence it becomes more comprehensive in its doctrines.

I just read a reasonable argument - I thought - the other day that argued biology should be regarded as a technical discipline like civil engineering and not a "science." Fields of research like physics, chemistry, and cosmology that deal in more exact mathematical models where "laws" appear to always be true and even universal throughout the universe (perhaps?) are probably more pure "sciences" and maybe falsifiability as a criteria is more prudent?

Hell... I can't figure any of this stuff out. I'm still learning how to more fully and properly understand "science" too, so, if I stated something incorrectly you'll pardon me please.

Everything is scientifically falsifiable.

I can't find it now, but i remember reading in Metro newspaper years ago that a satellite had been sent into orbit with the intention of measuring the distances between stars and galaxies, the speed they were travelling, the speed at which the distances were changing etc, etc.
Of course, the prediction by the satellite's moderators was that it would return readings similar to that of the fragments of a large explosion; in that the objects in question would be travelling away from each other, and decelerating as time passed. The idea was that, when more complex technology was developed, they would be able to use the information gathered in the experiment to trace the paths of these galaxies backwards until they all converged to a single point - ie. the big bang.
Anyway the readings came back, and the predictions were wrong. The distances between the objects were growing, but they seemed to be accelerating away from each other. no explanation for these findings could be given.
We have buildings full of machinery all over the world, and a mind-boggling amount of evidence to prove the big bang theory, but in the end we have to accept that what we can discover with all our technology is probably less than one billionth of reality, and using this evidence to predict the beginning of the universe, or indeed anything else about it, is probably as futile as trying to predict someone's personality using the information contained in the nucleus of one of their skin cells. I am not religious or spiritual in any way, but as far as I am concerned, the big bang theory is only as valid as Hinduism, Islam, Judaism or even the Flying Spaghetti Monster (google it!).
In any case, I hate to be a killjoy, but i do believe that the only way to really discover how the universe works is to stand outside it. Which is, of course, completely impossible.
