The Origin of the First Light In the Universe

StartsWithABang writes Before there were planets, galaxies, or even stars in the Universe, there really was light. We see that light, left over today, in the form of the Cosmic Microwave Background, or the remnant glow from the Big Bang. But these photons outnumber the matter in our Universe by more than a-billion-to-one, and are the most numerous thing around. So where did they first come from? Science has the answer.

    Don't fall into the trap. The sky has always been falling on our heads, whether it be foreign invaders, disease, nuclear war, the youth of today, asteroid strike, climate change, alien invasion etc. If one thing is constant throughout history it's that somehow there always seems to be a threat of sudden extinction, and when it's found to be overblown we simply find something else to replace it with. Sure one of them has to be right sooner or later, but worrying about it won't help

    Science isn't supposed to "have answers". The premise of a scientific theory is twofold:

    1. It must "work" given certain conditions.
    2. It must be able to be proved NOT to work outside of those conditions.

    Science says nothing about rights and wrongs, just whether things work or not within certain measurable parameters.

    Premise 2 is important. If you can't say what will make your theory break, then it's not clear you're really saying anything at all.

    Maybe the folks in the universe before us turned out the lights before they left . . . ?

    That's a bit like Bush talking about evolution and intelligent design, and claiming that "we have two theories". They both are theories, but only one is scientific. Same with these two theories about the origin of the universe. When scientific theory is demonstrably false, the theory is revised. When a theory fails to explain certain phenomena, it is refined. Scientific theories are put to the test. In religion, the theory is the test, even it that means denying what is staring you in the face. Or as another one put it: "Science needs to be seen to be believed, while matters of faith need to be believed to be seen".

    What if our model is wrong? I mean so wrong that crap has been built on crap that now has become a religion, a test of faith, do you believe the equations explain the system, or only predict how the system would look through the limits of the detection mechanism.

    The model is pretty good at predicting a bunch of stuff; even if the model is wrong, it has proven to be eminently useful in everyday applied science and engineering. So who cares if it turns out to be crap upon crap? Scientists would, and they'd be ecstatic. Proving that there are major problems with the currently held theory means more work, jobs, grants, awards for scientists, and a chance to go down in history.

    When a scientists measures something that doesn't fit the current models, they will generally suspect their equipment first. You could say it's reverence for established theories, but it is simple care to double check before announcing a ground breaking discovery to the world. You wouldn't call up your friends and family about winning the lottery before double-checking your ticket at least a few times either.

    They are definitely NOT both theories. Theories, by definition, have supporting evidence and are modified as new evidence is discovered. There is no supporting evidence for so-called "intelligent design"- it is a belief. The layman's misunderstanding of the word "theory" is why the ID idiots have been able to gain as much traction as they have.

    1) You see a criminal beating an innocent child to death. You have with you a cell phone, a tazer, and a handgun. Do you intervene? Does your intervention mean the criminal doesn't have free will?
