Question from Andrew:
Why do atheists like Stenger say that the universe can be eternal, when this does not hold?
Stenger argues that the universe can be eternal, non-created, extrapolating the law of conservation of energy-mass before the planck time, he says that because we do not see a violation to this law, the universe can perfectly be eternal.
But this is a fallacy as William Lane Craig exposed once. If the energy were eternal there would be no useful energy right now, it would have become useless, complete entropy an infinite time ago, and because we do not see this, the only conclusion is that the universe and the energy began a finite time ago. Where we Christians think, the best explanation is the creation by God.
Answer by SmartLX:
Even according to you, Stenger only said the universe can be eternal, not that it definitely is. If it isn’t, then God is only one possibility among who knows how many: spontaneous emergence (more on that in a sec), a previous universe, a deistic rather than theistic (let alone Christian) god and so on.
Anyway, there are at least three straightforward ways in which there can still be useful energy now after an eternity of existence. There might be others, but even one possible way is enough to keep someone like Craig from ruling out the possibility entirely.
1. There is infinite or potentially infinite energy as well as infinite time.
Our universe as we see it has existed for a finite amount of time since the Big Bang with a certain amount of matter and energy, but what if that only contained one portion of the available material of an endless universe or multiverse? Or can matter emerge regularly and spontaneously from the quantum foam as much as it likes, as long as the same amount of antimatter accompanies it and the total amount of “positive” energy stays constant? As Lawrence Krauss says, something can come from nothing if “nothing” is unstable.
2. The energy is periodically reclaimed.
Entropy doesn’t destroy energy (hence Stenger’s point), it only ends up radiating it towards the edges of the universe where it’s no use to anyone. If Big Bangs are regular rather than one-off occurrences, then there’s a long-standing hypothesis that the universe is first drawn together in a Big Crunch. The new singularity contains not only all the matter and energy of the crushed universe, but all the space as well. Whatever was lost to entropy is dragged back to a mathematical point, just like at the point of our own Big Bang, and the cycle can begin again.
3. The amount of available energy decreases exponentially.
The less energy there is, the slower it dissipates, the way a gush becomes a trickle when you tip out a bucket of water. Say that every billion years, the amount of available energy decreases by half. If so then a billion years ago there was twice as much, and two billion years from now there’ll be a quarter as much, but there will never, ever be none. It will approach zero (or, importantly, a non-zero constant) asymptotically, which is to say it will get closer and closer without ever reaching it. Perhaps the amount of energy we’re used to seeing in the world is practically nothing compared to the intense heat, light and motion that was everywhere in times gone by, with the universe in a state of near-saturation (perhaps asymptotically again). Without past reference points from before the Big Bang, which are probably impossible to attain, you can’t make a judgement that there can’t be this much energy now.
One final point: be very careful about expressions like “the best explanation” when discussing cosmology. If quantum mechanics have taught us anything, it’s that reality can be counter-intuitive, and the truth might well strike one as ridiculous. If there’s evidence for a claim then it’s a supportable claim, but if all it does is sound right then it’s worthless.

It All Comes Back To Jesus
Question from Tim:
Hello,
Thanks a lot for the website! If you guys are too busy to respond I understand.
Last year I finally managed to leave Christianity, but still have a few nagging doubts that I have been trying to resolve for some time now. My uncle told me that if I look at the evidence, I will see that the resurrection of Jesus is a fact. While I do doubt this, it is something that I feel like I need to learn about and take seriously. Do you know where I can find some resources addressing the resurrection from either an atheistic or neutral viewpoint? All I have managed to find so far are Christian ones.
Thanks!
Answer by SmartLX:
Don’t worry, we’d have to be a LOT busier not to be able to respond to every question we get.
This area of Christian apologetics is huge, as you’ll have seen by the sheer number of books specifically pushing it. It’s also a real sore point for believers when anyone questions even the divinity of Jesus, let alone his existence. That’s understandable since the whole of Christian doctrine hangs on the story of one man, and in the absence of physical evidence for that man the only traces of him are ancient documents.
There are a couple of starting points for you right here. My two long discussions in the comments of posts #271 and #574 with Rob (alias RP) cover a lot of ground and may suggest avenues of research. Post #271 itself contains links to earlier pieces of mine on specific documents and arguments.
As for things not on this site, the best-known critic of the New Testament and related documents is probably Bart Ehrman, so try one of his books. (He’s struck a nerve, because there are sites dedicated to answering everything he’s said.) A separate, highly-recommended book which challenges everything about Jesus is The Jesus Puzzle by Earl Doherty. Online, Jeffrey Jay Lowder has published a set of comprehensive responses to a wide selection from the apologetic arsenal, including William Lane Craig’s “empty tomb” argument and the entirety of Josh McDowell’s Evidence That Demands A Verdict.
YouTube is of course a treasure trove of individuals arguing both ways (Ehrman and Craig have many recorded debates on the subject, separately and together), but there you can also find one piece of work which prompted plenty of discussion when it came out: the independently produced documentary The God Who Wasn’t There. (It’s by the same group who debated Ray Comfort and Kirk Cameron on Nightline).
I hope the above gets you started, but don’t take anything you find as gospel, so to speak. Any significant point that’s been made in opposition to the divinity or resurrection of Jesus has been answered (how well it’s been answered is always debatable) by apologists as a matter of principle. This means that if you read a major point, you can find major discussions to go with it.
Go get stuck in, and let us know how you do.
