Trigonometric proof that the universe has to be much more than 6,000 years old.
Based on the known, current speed of light and simple trigonometry, Supernova SN1987A has to be 168,000 light years away, so if the speed of light is constant, it must have taken 168,000 years for the light from it to get to us. YEC's have tried to get around that difficulty by postulating that the speed of light was once faster than it is now. Unfortunately, that doesn't help their case at all because, if the speed of light was once faster than it is now, the supernova remnant would have to be much larger and much farther away than we now think it is. So much farther away, in fact, that even assuming that the speed of light were once much higher than it now is, it can be shown mathematically that it would have taken even longer for the light from it to get to us than we now think it did. Furthermore, the faster we postulate that the speed of light once was, the worse it looks for YEC! Of course LittleNipper will not understand or even try to understand the math involved, but any mathematically competent person will immediately see just how untenable the YEC position is if they take a look at that video.
Actually, what Creationists say is that God first made light and later created a source of that light. God also spread the universe out as a curtain. The Bible is way ahead of such problems as light years. And yet when it was written, only God knew that light isn't instantaneous.
