^first i want to start off by saying i havent studied everything there is to study in physics. i took two years of physics in highschool (one year was an advanced placement class, so it is supposed to be the equivalent of college physics). so as you could imagine, it was pretty basic stuff. everything i learned in those classes stemmed from principles that were proven in mathematics. so as far as i studied it, yes, i do trust all the physics i learned 100%.
you say i rejected hubbles law, but the truth is, i don't know a whole lot about it. i know what it is, but the actual mathematics behind it i have never studied, so there isnt much i can say about it. i am just skeptical towards the whole big bang theory. not to say that i reject all of this supposed 'evidence' for it, i just think there is a possibility that you could get the wrong conclusion from the data you have. the physics and chemistry i trust is the math. everything beyond that is just an educated guess.
i am finding a common trend in these 'arguments' we get in though. i question a lot of things. i can see how it comes off as im just being contrary, or ignorant, but really, i am just entertaining an idea that isnt generally accepted by the public. so basically, i dont want to say i 'rejected' those laws, because the truth is, i dont know enough about them to even do that.
also, i have no idea wtf cosmic microwave background radiation is. |
What I don't understand is why people are so reluctant to accept the big bang theory. The big bang is not particularly difficult to apprehend and comprehend. The universe had to start somewhere and somehow. The evidence for the origin of the universe is fairly abundant, and it points to the notion that it was all once a singularity. I'm going to try this in an extremely simplified way...
...
Hubble's law was an observational basis for the metric expansion of space. When the redshift of astronomical objects are measured it shows that everything in the Universe is moving away, that the universe is expanding. The universe is uniformly expanding everywhere. If the Universe is uniformly expanding, then if you work back logically there has to be a point where it was tiny, a point where it was a singularity... A point where it began.
...
This leads into a second piece of observational evidence I wish to give. Galactic evolution and distribution. Light takes a long time to reach us from other galaxies, it only moves a 300,000Km/s. So whenever you look up into the night sky you are seeing stars as they were thousands, if not millions, of years ago. When we observe galaxies that are billions of light years away we see something strange, they are quite primitive. When we observe a galaxy billions of light years away, they look far less developed than ours. The further we look back in time, the less developed they are. This shows that galaxy's are evolving, and we can observe the rate at which they evolve. this too shows the Universe had an origin.
This image demonstrates the evolution that I'm talking about...
...
Now onto the point you asked about, Cosmic microwave background radiation or CMBR. When the Big bang occurred at the beginning of time, photons were created and absorbed en masse. However, when some time passed the universe stopped producing and destroying these photons. These photons can now be observed as electromagnetic radiation, more specifically the microwave region of the electromagnetic spectrum. We have observed this leftover microwave radiation that was caused by the big bang. When you detune your TV and see the static, 1% of what you are seeing is the leftover microwave radiation from the big bang.
This is an extremely simplified explanation however.
I hope this has helped you understand the big bang little better

As for you questioning science and seeming like being ignorant. It's not the questioning the science that makes you seem ignorant or entertaining an idea that isn't accpeted, quite frankly that is welcomed, it is almost the definition of science to be honest. Anyone who questions science in a proper and respectful way is a friend of mine. However, last time I explained CMBR to you you replied with "THAHAHAHAHAHAHAHAHAHAHAHA HAHHAHAHAH!!!!!!!!!!!!!!!!!!!!!1111my god, you really have done it this time, highway star. you almost made me shit myself after this post!". But seeing as you admitted you didn't know about CMBR just, I'm assuming that you didn't read my explanation a few weeks ago at all, and just skipped it and proceeded to take the piss out of me... That's why people think you are ignorant.
The Universe had to begin somewhere and the evidence suggests that the big bang was the most likely origin. If you want to suggest alternate theories that also incorporates or debunk the evidence found, fine, please do so. But don't just take the piss, that is not questioning, it is trolling.
