Post A universe without purpose
I know many won't accept this and some of this is hard for me to fully comprehend but it is interesting...

A universe without purpose
New revelations in science have shown what a strange and remarkable universe we live in.

The illusion of purpose and design is perhaps the most pervasive illusion about nature that science has to confront on a daily basis. Everywhere we look, it appears that the world was designed so that we could flourish.

The position of the Earth around the sun, the presence of organic materials and water and a warm climate — all make life on our planet possible. Yet, with perhaps 100 billion solar systems in our galaxy alone, with ubiquitous water, carbon and hydrogen, it isn't surprising that these conditions would arise somewhere. And as to the diversity of life on Earth — as Darwin described more than 150 years ago and experiments ever since have validated — natural selection in evolving life forms can establish both diversity and order without any governing plan.

As a cosmologist, a scientist who studies the origin and evolution of the universe, I am painfully aware that our illusions nonetheless reflect a deep human need to assume that the existence of the Earth, of life and of the universe and the laws that govern it require something more profound. For many, to live in a universe that may have no purpose, and no creator, is unthinkable.

But science has taught us to think the unthinkable. Because when nature is the guide — rather than a priori prejudices, hopes, fears or desires — we are forced out of our comfort zone. One by one, pillars of classical logic have fallen by the wayside as science progressed in the 20th century, from Einstein's realization that measurements of space and time were not absolute but observer-dependent, to quantum mechanics, which not only put fundamental limits on what we can empirically know but also demonstrated that elementary particles and the atoms they form are doing a million seemingly impossible things at once.

And so it is that the 21st century has brought new revolutions and new revelations on a cosmic scale. Our picture of the universe has probably changed more in the lifetime of an octogenarian today than in all of human history. Eighty-seven years ago, as far as we knew, the universe consisted of a single galaxy, our Milky Way, surrounded by an eternal, static, empty void. Now we know that there are more than 100 billion galaxies in the observable universe, which began with the Big Bang 13.7 billion years ago. In its earliest moments, everything we now see as our universe — and much more — was contained in a volume smaller than the size of a single atom.

And so we continue to be surprised. We are like the early mapmakers redrawing the picture of the globe even as new continents were discovered. And just as those mapmakers confronted the realization that the Earth was not flat, we must confront facts that change what have seemed to be basic and fundamental concepts. Even our idea of nothingness has been altered.

We now know that most of the energy in the observable universe can be found not within galaxies but outside them, in otherwise empty space, which, for reasons we still cannot fathom, "weighs" something. But the use of the word "weight" is perhaps misleading because the energy of empty space is gravitationally repulsive. It pushes distant galaxies away from us at an ever-faster rate. Eventually they will recede faster than light and will be unobservable.

This has changed our vision of the future, which is now far bleaker. The longer we wait, the less of the universe we will be able to see. In hundreds of billions of years astronomers on some distant planet circling a distant star (Earth and our sun will be long gone) will observe the cosmos and find it much like our flawed vision at the turn of the last century: a single galaxy immersed in a seemingly endless dark, empty, static universe.

Out of this radically new image of the universe at large scale have also come new ideas about physics at a small scale. The Large Hadron Collider has given tantalizing hints that the origin of mass, and therefore of all that we can see, is a kind of cosmic accident. Experiments in the collider bolster evidence of the existence of the "Higgs field," which apparently just happened to form throughout space in our universe; it is only because all elementary particles interact with this field that they have the mass we observe today.

Most surprising of all, combining the ideas of general relativity and quantum mechanics, we can understand how it is possible that the entire universe, matter, radiation and even space itself could arise spontaneously out of nothing, without explicit divine intervention. Quantum mechanics' Heisenberg uncertainty principle expands what can possibly occur undetected in otherwise empty space. If gravity too is governed by quantum mechanics, then even whole new universes can spontaneously appear and disappear, which means our own universe may not be unique but instead part of a "multiverse."

Its definitely fascinating and i'm not one to dismiss anything based on the "what we know so far" methodology. The theory of relativity works for some things, but doesn't work for others. Quantum physics then works for things general relativity doesn't work with. They still haven't pieced the two together because they don't work when applied to the other. Its the great mystery of our time to figure out why things work so much differently here compared to out there.

The other conundrum is life. There's a ton of theories, but they all seem to go against the general theory of life cannot be created except from life. Every scientific study has come up with the same result, so that leaves the biggest hole in science. Its the one thing that has never been able to be verified via experiment or study. We can prove relativity, we can prove quantum physics, and we can recreate the experience of black holes on a computer, even though we've never physically seen one, but life has never been recreated or found even places where they believe water exists.

Anyway you look at it, it is tough to comprehend. Science always seems to ask new questions more than it answer, which is never a bad thing.

I agree 100%. I can't stand articles that claim to "prove" or "disprove" intelligent design. There's no way of knowing. There's no signature or evidence that will ever suggest what happened. Even if we "rewind the stars" to perfection and potentially witness "the big bang" you still can't prove that it wasn't some creator that set the experiment in motion.

WOW. I agree with WJB on this.

B-I-N-G-O... Nice to see that folks from both sides can find common ground!

On a large scale, the term "purpose" is irrelevant.

Even if you were to say god is the purpose, that still fails to really provide a purpose. It's more a less just a copout--you're using god as a block to relieve yourself of the burden of thinking. (You're here to serve god--why does he need to be served? What is the purpose for that?)

Row, row, row your boat,
Gently down the stream.
Merrily, merrily, merrily, merrily,
Life is but a dream.

Hmmm, I wonder who he meant with the rewind the stars comment? :-k

"could arise spontaneously out of nothing, without explicit divine intervention"

The author doesn't attempt to prove or disprove anything about the existence of a divine creator - he only to say it is possible that the universe came into existence without one, not that it did come into existence without one.

Given that the god hypothesis cannot be falsified, questions as to whether god exists or not are not the realm of science. Just as attempting to insert the god hypothesis into science simply is not science (eg intelligent design is not a scientific theory).
