It's worth reading the contents of the blue box in that article, Digsbe. To paraphrase/re-spin it here:Also, being able to see stars billions of light years away also poses a problem for the big bang. Light-travel time: a problem for the big bang
"Scientists have been coming up with solutions to this problem since at least 1981 - but some of their possible solutions have since been proven incorrect, and no-one can agree on which of the remaining solutions is the correct one".
If the problem has lots of possible solutions and our biggest worry is working out which one actually happened, I wouldn't say that the problem itself is that much of a threat.
I'll give you a quick tour through our sense of scale of the universe, as measured by the speed of light. Light travels ~300,000,000 meters every second, which is phenomenally fast - but only on our human scale. It takes over 8 minutes from light to get to the Earth from the Sun - that is, if the sun went out right now, we wouldn't notice for another 499 seconds. The speed of light is one of the reasons that we find exploring other planets a hardship - if we sent a remote-controlled buggy to Mars, for example, then it would take anywhere between 3 and 22 minutes (depending on where the planets are in their orbits) for it to send us a radio transmission; if you take into account that we'd then have to send instructions back the same distance then simple calculations say that it can be up to 44 minutes from the buggy telling Earth "there's a crater up ahead" to the buggy receiving instructions from Earth saying "stop!".
That's just Mars. It takes light (on average) over 4 hours to get to Neptune, and over 6.5 hours to get to Pluto at it's furthest. The Voyager 1 probe - the furthest thing we've sent out of the solar system - sees sunlight 14.6 hours after it was first emitted by the sun - if you were on Voyager looking back at Earth right now, you'd see us as we were over half a day ago, looking back through time.
Expand outwards from the solar system, and the distances get a little larger. The closest star to Earth is Proxima Centauri, which is a mere 4.2 light-years away. Just to hammer that home - any aliens currently looking at us from near Proxima Centauri would see Earth in early 2006. They'd never have heard of Barack Obama.
Let's scale out again. We live, as I'm sure you're aware, in a galaxy called the Milky Way. The size of the milky way might be bigger than you were expecting, though; it's certainly a little bigger than what we've been talking about so far - to be honest, it was bigger than I thought it was before I just looked it up. The Milky Way is discus-shaped. At it's thickest, it's 1000 light-years from top to bottom. The big distance, though, is it's diameter; it's ~100,000 light-years wide. As a point of reference, YECers generally claim that the universe was created spontaneously about 6000 years ago - according to YEC, we should be able to see only ~10% of our own galaxy, and those furthest stars would be brand-new, completely newly created. Instead, we can see stars that are 10 times further away than that within our own galaxy - and that's even ignoring other galaxies. If you look deeper and deeper into the sky, the furthest object we have seen is calculated to be ~13 billion lightyears away.
The universe is big. While there is the occasional contention about the extremely far objects we can image, we can see objects over 2 million light-years away with the naked eye - and most of our galaxy is further from us than the 6000 light-years which YEC claims should be the limit of our vision.
