Why do the men in white coats want us to believe that the universe was created by a big bang?
Is it just me or does that sound stupid?
actually they do not care at all if you believe it or not, they are just highly intelligent people who are using rational evidence to make theories. i will share with you the most compelling piece of evidence which proves beyond any doubt that the universe is expanding. and if the universe is expanding... well, it had to start somewhere right? it's just a logical conclusion formulated and agreed upon by very intelligent people, and they didnt just pull it out of their butts.
so here is how we know the universe is expanding: the doppler effect. This is an effect observed with waves, most observably with sound and light waves. Basically, it says that waves moving toward you have a shorter wavelength, and waves moving away from you have a longer wavelength.
( ( ( (x)))) -->
Kind of like that, the waves are closer together at the front, kind of like they are being bunched up, they are staying closer to the object(x) since it is moving and getting closer to them. This is the Doppler effect. With sound waves, this effect means that coming toward you, sound waves have a shorter wavelength(notice that the distance between each wave is shorter) and a higher frequency(notice that more waves would pass a given point per second since they're closer together) the formula is v=fw where v is velocity, f is frequency and w is wavelength; as you can see, since v is constant(the speed of light) f and w are inversely proportional so when one goes up, the other goes down. This higher frequency results in a higher pitch of the sound. This has been easily observed with sound. this means that the waves coming from an object moving away from you has a lower frequency.
When dealing with light, these differences in wavelentgh and frequency actually leads to a change in color, because the different colors just correspond to different wavelengths of light.(speeds must be very high to observe these changes) When an object is moving toward us, the wavelength is shorter and the frequency is higher, so we observe a "blue shift" because blue has the highest frequency, and when an object is moving farther away, the frequency is lower and wavelenth is longer, so we observe a "red shift," since red has the highest frequency(lowest wavelength, it looks longer, see the 'diagram' i tried to represent above...)
Well, we currently observe a red shift in other stars using strong telescopes, meaning that everything in any direction is getting farther and farther away from us and therefore, the universe is expanding.
i hope i gave you some insight into some of the observations that are made before such a theory is created. science has much evidence, which is why it is supported by so many intelligent people. scientists are very skeptical and will not believe anything unless proper evidence is presented to them, and even then will not really believe it, just admit that it may have happened that way. like the big bang theory, we didn't say "this is what happened, deal with it", we say "hey, it seems from the evidence that this is a possibility and makes a lot of sense... but it's still just a theory."
