Another eternal cosmology model shot down by the BGV Theorem

I saw this article on Evolution News, and thought it might a good time for me to review the BGV Theorem that Dr. William Lane Craig brings up in all his recent debates.

First, let’s review the BGV Theorem.

The Borde-Guth-Vilenkin (BGV) theorem shows that every universe that is on balance expanding must have a space-time boundary in the past (a beginning). Even cyclical models of the universe count as expanding “on balance” if their later expansions go further than the previous ones.

Here’s the article from Evolution News:

A key argument in Stephen Meyer’s Return of the God Hypothesis centers on the universe having a beginning. He argues that the beginning points to the cosmos resulting from the mind of a creator. Meyer’s case for the God Hypothesis includes discrediting the claim that cyclical cosmological models could avoid a beginning by his appealing to the Borde-Guth-Vilenkin (BGV) theorem. His reasoning was recently reaffirmed by University of Buffalo physicists Will Kinney and Nina Stein in their analysis of Ijjas and Steinhardt’s (IS) cosmological model. They published their results in the Journal of Cosmology and Astroparticle Physics.

By the way, the Kindle edition of the Meyer book is on sale for $2.99 right now. Get it while it’s cheap!

Correspondent Charlotte Hsu summarizes the research at Phys.org:

“People proposed bouncing universes to make the universe infinite into the past, but what we show is that one of the newest types of these models doesn’t work,” says Kinney, Ph.D., professor of physics in the UB College of Arts and Sciences. “In this new type of model, which addresses problems with entropy, even if the universe has cycles, it still has to have a beginning.”

Kinney and Stein applied the BGV theorem to the IS model, which I have previously critiqued. Anna Ijjas and Paul Steinhardt propose that the universe expanded, then contracted, and then bounced back into an expansion stage in a never-ending cycle. Each iteration grows vastly larger than the previous one, so the universe is on average always expanding. Kinney and Stein rigorously demonstrate that the BGV theorem mandates the IS model being “geodesically pastincomplete,” meaning that spacetime had an absolute beginning:

In this paper, we use the BGV theorem to demonstrate that growth in the scale factor inevitably means that the spacetime is geodesically pastincomplete. … This result is completely general: any bouncing spacetime which obeys the condition for entropy dissipation and the Null Energy Condition outside the bounce must be geodesically incomplete. This is consistent with the BGV theorem, which shows that any spacetime for which the average Hubble parameter is positive must be similarly geodesically incomplete. The IS cosmology satisfies this condition and therefore cannot be past eternal, independent of the details of the dynamics.

In other words, this new cyclical / oscillating model of the universe does not avoid the need for a beginning… and a cause of the creation event.

So, when you hear Dr. Craig talking about the BGV Theorem in debates, now you’ll know what it’s for. It’s real, and it works.

Atheist Jerry Coyne explains why morality is impossible for atheists

Let’s review what you need in your worldview in order to have a rationally grounded system of morality.

You need 5 things:

1) Objective moral values

There needs to be a way to distinguish what is good from what is bad. For example, the moral standard might specify that being kind to children is good, but torturing them for fun is bad. If the standard is purely subjective, then people could believe anything and each person would be justified in doing right in their own eyes. Even a “social contract” is just based on people’s opinions. So we need a standard that applies regardless of what people’s individual and collective opinions are.

2) Objective moral duties

Moral duties (moral obligations) refer to the actions that are obligatory based on the moral values defined in 1). Suppose we spot you 1) as an atheist. Why are you obligated to do the good thing, rather than the bad thing? To whom is this obligation owed? Why is rational for you to limit your actions based upon this obligation when it is against your self-interest? Why let other people’s expectations decide what is good for you, especially if you can avoid the consequences of their disapproval?

3) Moral accountability

Suppose we spot you 1) and 2) as an atheist. What difference does it make to you if you just go ahead and disregard your moral obligations to whomever? Is there any reward or punishment for your choice to do right or do wrong? What’s in it for you?

4) Free will

In order for agents to make free moral choices, they must be able to act or abstain from acting by exercising their free will. If there is no free will, then moral choices are impossible. If there are no moral choices, then no one can be held responsible for anything they do. If there is no moral responsibility, then there can be no praise and blame. But then it becomes impossible to praise any action as good or evil.

5) Ultimate significance

Finally, beyond the concept of reward and punishment in 3), we can also ask the question “what does it matter?”. Suppose you do live a good life and you get a reward: 1000 chocolate sundaes. And when you’ve finished eating them, you die for real and that’s the end. In other words, the reward is satisfying, but not really meaningful, ultimately. It’s hard to see how moral actions can be meaningful, ultimately, unless their consequences last on into the future.

Theism rationally grounds all 5 of these. Atheism cannot ground any of them.

Let’s take a look at #4: free will and see how atheism deals with that.

Atheism and free will?

Here’s prominent atheist Jerry Coyne’s editorial in USA Today to explain why atheists can’t ground free will.

Excerpt:

And that’s what neurobiology is telling us: Our brains are simply meat computers that, like real computers, are programmed by our genes and experiences to convert an array of inputs into a predetermined output. Recent experiments involving brain scans show that when a subject “decides” to push a button on the left or right side of a computer, the choice can be predicted by brain activity at least seven seconds before the subject is consciously aware of having made it. (These studies use crude imaging techniques based on blood flow, and I suspect that future understanding of the brain will allow us to predict many of our decisions far earlier than seven seconds in advance.) “Decisions” made like that aren’t conscious ones. And if our choices are unconscious, with some determined well before the moment we think we’ve made them, then we don’t have free will in any meaningful sense.

If you don’t have free will, then you can’t make moral choices, and you can’t be held morally responsible. No free will means no morality.

Here are some more atheists to explain how atheists view morality.

William Provine says atheists have no free will, no moral accountability and no moral significance:

Let me summarize my views on what modern evolutionary biology tells us loud and clear — and these are basically Darwin’s views. There are no gods, no purposes, and no goal-directed forces of any kind. There is no life after death. When I die, I am absolutely certain that I am going to be dead. That’s the end of me. There is no ultimate foundation for ethics, no ultimate meaning in life, and no free will for humans, either.

Richard Dawkins says atheists have no objective moral standards:

In a universe of blind physical forces and genetic replication, some people are going to get hurt, other people are going to get lucky, and you won’t find any rhyme or reason in it, or any justice. The universe that we observe has precisely the properties we should expect if there is, at bottom, no design, no purpose, no evil and no good, nothing but blind, pitiless indifference… DNA neither knows nor cares. DNA just is. And we dance to its music. (Richard Dawkins, River Out of Eden: A Darwinian View of Life (1995))

When village atheists talk about how they can be moral without God, it’s important to ask them to justify the minimum requirements for rational morality. Atheists may act inconsistently with their worldview, believing in free will, expecting praise and blame for complying with the arbitrary standards of their peer group, etc. But there is nothing more to morality on atheism that imitating the herd – at least when the herd is around to watch them. And when the herd loses its Judeo-Christian foundation – watch out. That’s when the real atheism comes out – the atheism that we’ve seen before in countries that turned their backs on God, and the moral law. When God disappears from a society, anything is permissible.

Gun control activists get CDC to bury study on legal ownership and self-defense

I saw an interesting article over at Daily Wire about a study on guns and crime produced by the CDC. It’s very interesting to see what a study from the secular left has to say about gun-ownership by law-abiding Americans, and the effect of self-defense on crime rates.

It says:

A key federal agency worked with gun control advocates to bury a study that showed law-abiding firearms owners use them to protect themselves millions of times per year, according to a report.

The Centers for Disease Control and Prevention (CDC) deleted a reference to the study, which it had commissioned, after gun-control advocates said it made passing new gun laws more difficult. The pro-Second Amendment site The Reload reported that the White House and powerful Illinois Democratic Sen. Dick Durbin helped arrange a series of meetings at which the gun control advocates convinced the agency to hide the study.

“[T]hat 2.5 Million number needs to be killed, buried, dug up, killed again and buried again,” Mark Bryant, head of the Gun Violence Archive, wrote to CDC officials after a meeting. “It is highly misleading, is used out of context and I honestly believe it has zero value – even as an outlier point in honest DGU discussions.”

When there’s a conflict between gun ban advocates, who are driven by feelings, and law-abiding gun owners, who are driven by facts, who wins?

Bryant’s email was one of a handful obtained by The Reload which illustrate how gun control lobbyists were triggered by the study by Florida State University Criminology Professor Gary Kleck.

[…]Bryant complained that Kleck’s estimate was “misinformation” and should be eliminated from the CDC’s website because gun-rights advocates were using it as ammunition for their Second Amendment arguments.

The CDC initially stood by the study and listed it in the “Fast Facts: Firearm Violence Prevention” portion of its website. But after a September 15, 2021, virtual meeting with gun control advocates, the agency assured them it would revise the section in 2022, according to a December 10, 2021, email obtained by The Reload.

When science facts conflict with secular left left feelings, then government policy adapts to the feelings and ignores the facts.

The peer-reviewed research

Whenever I get into discussions about gun control, I always mention two academic books by John R. Lott and Joyce Lee Malcolm.

Here is a paper by Dr. Malcolm that summarizes one of the key points of her book.

Excerpt:

Tracing the history of gun control in the United Kingdom since the late 19th century, this article details how the government has arrogated to itself a monopoly on the right to use force. The consequence has been a tremendous increase in violent crime, and harsh punishment for crime victims who dare to fight back. The article is based on the author’s most recent book, Guns and Violence: The English Experience (Harvard University Press, 2002). Joyce Malcom is professor of history at Bentley College, in Waltham, Massachusetts. She is also author of To Keep and Bear Arms: The Origins of an AngloAmerican Right (Harvard University Press, 1994).

And the result of the 1997 gun ban:

The result of the ban has been costly. Thousands of weapons were confiscated at great financial cost to the public. Hundreds of thousands of police hours were devoted to the task. But in the six years since the 1997 handgun ban, crimes with the very weapons banned have more than doubled, and firearm crime has increased markedly. In 2002, for the fourth consecutive year, gun crime in England and Wales rose—by 35 percent for all firearms, and by a whopping 46 percent for the banned handguns. Nearly 10,000 firearms offences were committed.

[…]According to Scotland Yard, in the four years from 1991 to 1995 crimes against the person in England‟s inner cities increased by 91 percent. In the four years from 1997 to 2001 the rate of violent crime more than doubled. The UK murder rate for 2002 was the highest for a century.

I think that peer-reviewed studies – from Harvard University, no less – should be useful to those of us who believe in the right of self-defense for law-abiding people. The book by economist John Lott, linked above, compares the crime rates of all U.S. states that have enacted concealed carry laws, and concludes that violent crime rates dropped after law-abiding citizens were allowed to carry legally-owned firearms. That’s the mirror image of Dr. Malcolm’s Harvard study, but both studies affirm the same conclusion – more legal firearm ownership means less crime.
