Keeping in mind, people 200 years from now may look back on this comment and go "Ha ha, people used to think crazy things like 'the universe is only 14 billion years old'".
- dhughes 15y agoWell, that is true in 200 years the universe will be 14,000,000,200 years-old ;)
- gnaritas 15y agoScience doesn't really work that way; we don't look back at Newton and think what an idiot, nor will future people think so of us. Our measurements get more accurate over time but that doesn't mean our current measurements are wrong or ever will be; they're simply as accurate as they can be now, which is pretty damn accurate. No one in the future is going to suddenly find out the universe is 100 billion years old and we had it all wrong.
- palish 15y agoOh, the ego of us humans. The one constant throughout the history of science is that Nature's imagination is substantially more vast than our own. What if we discover that "old" has an entirely different meaning after light has traveled for some billions of years? I can't think of any reasonable examples, except I remember my friend showing me a very old book about Chemistry. It had chapters about how "everything is made of a mixture of earth, water, and fire". And so on.
- brass_cannon 15y agoTo your point, someone used the Hubble Effect in the other HN thread on this story to show that this observation is actually closer to 9.5 billion years old, which is significantly different than it being 12 billion years old.
- mturmon 15y agoFor some mind-expanding examples of the (probable) insufficiency of our concept of "universe," see: http://en.wikipedia.org/wiki/Multiverse#Tegmark.27s_classification http://en.wikipedia.org/wiki/Multiverse#Tegmark.27s_classifi... At various levels, it's possible that our own Hubble volume ("universe") is only a small stable bubble in a much larger physical system.
- gnaritas 15y ago> I can't think of any reasonable examples Exactly, no one can, because your premise is wrong. > except I remember my friend showing me a very old book about Chemistry That was pre-science. If you can't find a modern day example there's a reason for that, the wheel of science only turns one way, forward. New science rarely if ever disproves past science, what it does is give us more accurate theories; the old theories are still correct within the framework they were made in. Einstein for example, didn't prove Newton wrong, he just had a theory that was even more accurate than Newton's. It's not ego, it's how the process is meant to work.
