The Universe Is 13.73 Billion Years Old

CaptainCarrot writes "Phil Plait, aka The Bad Astronomer has summarized for his readers the new results released by NASA from the Wilkinson Microwave Anisotropy Probe (WMAP), which has been surveying the 3K microwave radiation left over from the Big Bang. Some of the most interesting results: The age of the universe is now known to unprecedented accuracy: 13.73 billion years old, +/- 120 million. Spacetime is flat to within a 2% error margin. And ordinary matter and energy account for only 4.62% of the universe's total. Plait's comment on the age result: 'Some people might say it doesn't look a day over 6000 years. They're wrong.'"

As we know, time dilation means that a spaceship flying for a year at a high enough speed could return to Earth only to find that the crew's families have been dead for a thousand years due to local time passing at different rates for objects moving at different speeds. For this reason, a photon moves at the speed of light no matter how fast you are moving relative to that photon. Similarly, from our frame of reference inside the Universe, 13.73 billion years have elapsed. From another frame of reference, it is 6000 years old and not a minute more.

      According to the Biblical calendar, the 6000 years (actually 5768 years) is NOT counted from the beginning of the creation of the universe -- it's counted from the creation of the human soul (ie, "Adam"), which happens at the very tail-end of the creation account. That's the point at which an Earth-based accounting of time becomes sensible. The creation story is not meant to be a literal account of anything, and in fact the Talmud explicitly states that it was written in such a way as to intentionally conceal information. I have no idea why anyone would dispute the findings of science when they seem to conflict with a literal reading of the Bible which was NOT INTENDED, when the metaphorical/metaphysical description is EXPLICITLY referred to in the earliest commentaries.

    I know a number of Catholics and other christians, a number of Jews, and a handful of Buddhists who would all reject your attempted "evidence" for a number of reasons.

    The base reason, though, why you're entirely wrong, is twofold:

    Number one, you're assuming that science is unchangeable and that what came first is inevitably more accurate. While this may be acceptable for scripture, it's exactly opposite to what's acceptable for science.

    Why is this?

    Because science is based on the assumption that while it may be the most useful explanation for the way things work at the moment, it may possibly be disproved with better equipment and techniques at some time in the future. Hence, this 'revisionism' that your link claims is somehow a bad thing is, instead, just the way science works.

    Secondly, each of the explanations for the apparent "young age" given is incomplete. The age of Niagara falls, for instance, does not take into account geological uplift, vulcanism, deposition of sediments, or any other of the ways in which erosion is countered. The assertion that the sun is "getting smaller" has been measured; Heimholz' calculations were based on incomplete information and on an incorrect assumption that the sun was burning according to the standard oxygen-fuel model--being as nuclear fusion had not yet been discovered.

    You do not have to be an atheist to practice good science. Many, many men and women of faith have no problem with scientific thought and principles, because they understand that science is not a -threat- to their beliefs, but rather a -celebration- of them. If your faith is so fragile that anything which does not read exactly according to your preconceived notion, your personal interpretation, of what the bible says is counted as a threat, then the problem lies not with science, but with you.

    That about sums it up. Even the Catholic Church eventually conceded that Earth was neither flat nor the center of the universe. Faith is not belief without thinking. It is not mindless. It must be tempered by common sense.

    Nor does reasoning require a lack of faith. There was a quote, but I can't remember it precisely and I can't find the attribution, so I'll just paraphrase it as best I can remember... something like "I can know how the sun gives us light, but that makes it no less magical." The belief that God created all does not in any way negate the desire to understand that creation, to understand how it was created, to understand the structure of the universe. Belief does not require accepting as literal truth words that were written to be understood by relatively primitive people millennia ago....

    You know, the interesting thing is that the Bible doesn't say that the Earth is 6,000 years old.

    In fact, the majority of Jews - from whom the scripture came - do not believe it is 6,000 years old.

    Nor do the 2 billion Catholics in the world.

    Nor do the nearly 1 billion (maybe more) Muslims in the world.

    Yet they all believe in the books of Moses.

    The belief that the Earth was formed in 4,004 B.C. is held only by a small, minority sect of protestants who insist on interpreting the Bible literally. Problem is, that a literal interpretation of the Bible doesn't support this theory - there are gaps in the genealogies which make arriving at an exact date impossible. In fact, you can't even get a ballpark figure using literal interpretation, because the books weren't written as an historical or scientific reference. So things get left out that you would need to know to determine even the approximate dates.

    Suppose, for an instant, that you are God, telling Moses how you created the world:
    God: In one femtosecond, I created all the matter in the Universe.
    Moses: What's a femto-second? How many days is that?
    God: It's a, wait, oh, nevermind... Let me rephrase that: I spoke and created the Universe on the first day...

    It's not false, but it's not precise either. However, it is as precise as could be written down at the time, because the concept of a femto-second wouldn't become widely known for another 40 centuries.

    No matter what the topic, you can find people who will read their particular biases into anything. You can find the same behavior among the Da Vinci code believers who think somehow that, in spite of the book being fiction, the Catholic Church is "hiding the real truth". Kind of like the 9/11 and JFK conspiracy theorists.

    I'm not sure why people like to trot out the 6,000 year old theory every time someone mentions the age of the Universe. Perhaps it is because they're seeking an opportunity to tar the faiths of the world with the brush of ignorance. Perhaps their ignorance of religion allows them to believe that all believers think this way. Regardless, it is getting a little old, and quite frankly, pedantic.
