Alexander Vilenkin: “All the evidence we have says that the universe had a beginning”

1 Comment

I’ve decided to explain why physicists believe that there was a creation event in this post. That is to say, I’ve decided to let famous cosmologist Alexander Vilenkin do it.

From Uncommon Descent.

Excerpt:

Did the cosmos have a beginning? The Big Bang theory seems to suggest it did, but in recent decades, cosmologists have concocted elaborate theories – for example, an eternally inflating universe or a cyclic universe – which claim to avoid the need for a beginning of the cosmos. Now it appears that the universe really had a beginning after all, even if it wasn’t necessarily the Big Bang.

At a meeting of scientists – titled “State of the Universe” – convened last week at Cambridge University to honor Stephen Hawking’s 70th birthday, cosmologist Alexander Vilenkin of Tufts University in Boston presented evidence that the universe is not eternal after all, leaving scientists at a loss to explain how the cosmos got started without a supernatural creator. The meeting was reported in New Scientist magazine (Why physicists can’t avoid a creation event, 11 January 2012).

[…]In his presentation, Professor Vilenkin discussed three theories which claim to avoid the need for a beginning of the cosmos.

The three theories are chaotic inflationary model, the oscillating model and quantum gravity model. Regular readers will know that those have all been addressed in William Lane Craig’s peer-reviewed paper that evaluates alternatives to the standard Big Bang cosmology.

But let’s see what Vilenkin said.

More:

One popular theory is eternal inflation. Most readers will be familiar with the theory of inflation, which says that the universe increased in volume by a factor of at least 10^78 in its very early stages (from 10^−36 seconds after the Big Bang to sometime between 10^−33 and 10^−32 seconds), before settling into the slower rate of expansion that we see today. The theory of eternal inflation goes further, and holds that the universe is constantly giving birth to smaller “bubble” universes within an ever-expanding multiverse. Each bubble universe undergoes its own initial period of inflation. In some versions of the theory, the bubbles go both backwards and forwards in time, allowing the possibility of an infinite past. Trouble is, the value of one particular cosmic parameter rules out that possibility:

But in 2003, a team including Vilenkin and Guth considered what eternal inflation would mean for the Hubble constant, which describes mathematically the expansion of the universe. They found that the equations didn’t work (Physical Review Letters, DOI: 10.1103/physrevlett.90.151301). “You can’t construct a space-time with this property,” says Vilenkin. It turns out that the constant has a lower limit that prevents inflation in both time directions. “It can’t possibly be eternal in the past,” says Vilenkin. “There must be some kind of boundary.”

A second option explored by Vilenkin was that of a cyclic universe, where the universe goes through an infinite series of big bangs and crunches, with no specific beginning. It was even claimed that a cyclic universe could explain the low observed value of the cosmological constant. But as Vilenkin found, there’s a problem if you look at the disorder in the universe:

Disorder increases with time. So following each cycle, the universe must get more and more disordered. But if there has already been an infinite number of cycles, the universe we inhabit now should be in a state of maximum disorder. Such a universe would be uniformly lukewarm and featureless, and definitely lacking such complicated beings as stars, planets and physicists – nothing like the one we see around us.

One way around that is to propose that the universe just gets bigger with every cycle. Then the amount of disorder per volume doesn’t increase, so needn’t reach the maximum. But Vilenkin found that this scenario falls prey to the same mathematical argument as eternal inflation: if your universe keeps getting bigger, it must have started somewhere.

However, Vilenkin’s options were not exhausted yet. There was another possibility: that the universe had sprung from an eternal cosmic egg:

Vilenkin’s final strike is an attack on a third, lesser-known proposal that the cosmos existed eternally in a static state called the cosmic egg. This finally “cracked” to create the big bang, leading to the expanding universe we see today. Late last year Vilenkin and graduate student Audrey Mithani showed that the egg could not have existed forever after all, as quantum instabilities would force it to collapse after a finite amount of time (arxiv.org/abs/1110.4096). If it cracked instead, leading to the big bang, then this must have happened before it collapsed – and therefore also after a finite amount of time.

“This is also not a good candidate for a beginningless universe,” Vilenkin concludes.

So at the end of the day, what is Vilenkin’s verdict?

“All the evidence we have says that the universe had a beginning.”

This is consistent with the Borde-Guth-Vilenkin Theorem, which I blogged about before, and which William Lane Craig leveraged to his advantage in his debate with Peter Millican.

The Borde-Guth-Vilenkin (BGV) proof shows that every universe that expands must have a space-time boundary in the past. That means that no expanding universe, no matter what the model, can be eternal into the past. Even speculative alternative cosmologies do not escape the need for a beginning.

Conclusion

If the universe came into being out of nothing, which seems to be the case from science, then the universe has a cause. Things do not pop into being, uncaused, out of nothing. The cause of the universe must be transcendent and supernatural. It must be uncaused, because there cannot be an infinite regress of causes. It must be eternal, because it created time. It must be non-physical, because it created space. There are only two possibilities for such a cause. It could be an abstract object or an agent. Abstract objects cannot cause effects. Therefore, the cause is an agent.

After legalizing marijuana, Colorado sees higher number of “daily” users

10 Comments

Lee Strobel tweeted this story from the Denver Post.

Excerpt:

As marijuana legalization took hold in Colorado, the estimated percentage of regular cannabis users in the state jumped to the second-highest level in the country, according to new federal data.

When asked, roughly one out of every eight Colorado residents over the age of 12 reported using marijuana in the previous month. Only Rhode Island topped Colorado in the percentage of residents who reported using marijuana as frequently.

The results come from the National Survey on Drug Use and Health and represent the average of estimates gathered in 2012 and 2013.

[…]State-specific data from the survey are averaged over two-year periods to compensate for relatively small sample sizes.

For the 2011-12 period, 10.4 percent of Coloradans 12 and older reported using marijuana in the month prior to being surveyed. That placed Colorado seventh in the country for monthly marijuana use.

Monthly use in Colorado jumped to 12.7 percent — a 22 percent increase — in the 2012-13 data. The result means the survey estimates about 530,000 people in Colorado use marijuana at least once a month.

Nationally, monthly marijuana use by people 12 and older nudged upward by about 4 percent to 7.4 percent. In Washington state — which, like Colorado, in 2012 legalized marijuana use and limited possession for adults — monthly marijuana use rose by about 20 percent to 12.3 percent.

Kleiman said researchers will get a better idea about marijuana use in Colorado once they are able to zoom in on data showing how many people use marijuana daily. A study commissioned by Colorado’s Marijuana Enforcement Division this year found that people who use marijuana almost every day account for about 22 percent of cannabis users in Colorado but consume nearly 67 percent of the marijuana used. Other studies have warned about a possible uptick in heavy marijuana use.

“The fraction of people who are monthly users who are in fact daily users has gone way, way up,” Kleiman said.

Monthly marijuana use increased across all age groups in Colorado, according to the new survey numbers. The number of people who reported using marijuana in the past year also increased in Colorado in the 2012-13 data, but the state ranked only sixth nationally in the measurement. Measurements for alcohol consumption and illicit drug use increased, as well.

What will be interesting will be to see how this increased usage affects tax revenues and the crime rate. I think when more people use mind-altering drugs, it is going to harm their ability to get and keep jobs, which affects tax revenue. And when people are addicted to something, they are more inclined to take a risk on committing a crime to get the money to pay for their next fix. Should be interesting to learn from Colorado’s little experiment.

Archaeologists discover entrance to Herod’s palace near Bethlehem

Herod's palace
Herod’s palace

Baptist Press reports on the story.

Full text:

Israeli archeologists have uncovered an impressive entrance to Herod’s palace at Herodium. Located only three miles southeast of Bethlehem, Herodium played an important part in the events surrounding the early life of Christ.

The December announcement by Hebrew University archeologists Roi Porat, Yakov Kalman and Rachel Chachy dovetails well with the seasonal interest in the nativity accounts of Luke and Matthew in the New Testament.

While both Luke and Matthew wrote that King Herod governed Judea during the era of Jesus’ birth at Bethlehem (Luke 1:5, Matthew 2:1), they included nothing concerning Herod’s massive palace/fortress complex at nearby Herodium.

Herodium, like Herod’s other isolated palace/fortress complexes at Masada and Machaerus, was built on a mountain. To enhance its impressive scale, Herod artificially extended the height of the hill to make it the tallest mountain in the Judean desert.

While the site included the usual Herodian luxuries such as a palace, bathhouse, theatre and garden, Herodium was essentially a fortress, a place where Herod could find refuge if his people revolted.

Herod’s fear of a Jewish revolt led him to establish many fortresses in both urban centers (he maintained two in Jerusalem itself) and in isolated rural areas away from the urban centers.

A small community close to the fortress housed the construction teams and, later, the garrison soldiers and palace servants. The servants who waited on the king indeed worked in an impressive palace.

The newly uncovered entranceway apparently was still being constructed near the time of the monarch’s death.

As shown in one of the photographs, the entryway included three levels of arches in a 65-foot corridor that was 19 feet across and 65 feet in height leading to the palace’s courtyard. Curiously enough, the nearly completed entrance was abruptly stopped and backfilled around the time of Herod’s death. The archeologists speculated that the now-aging Herod instead sought to convert the entire palace into a memorial mound for his upcoming burial at the site.

Indeed, Herod’s plans for Herodium unfolded as Jesus was born and as He spent His early life in nearby Bethlehem. When the magi arrived in Jerusalem and announced they had come to worship the “king of the Jews,” Herod sent them to Bethlehem after learning the location of the Messiah’s birthplace from the chief priests and learned scholars. The monarch hoped to ascertain from the magi which of the town’s small children was the designated royal candidate. Then Herod hoped to execute the child (Matthew 2:1-8, 2:16).

When the magi failed to return with this information, Herod ordered his soldiers into Bethlehem to murder all children age 2 and under. Warned to flee to Egypt, the holy family escaped Herod’s plans, but an undisclosed number of children were killed by Herod’s soldiers. Although never stated in the biblical account, the soldiers who carried out the old king’s infamous order were either stationed in Jerusalem (seven miles from Bethlehem) or in the closer post at Herodium. In fact, Herodium overlooked Bethlehem and could have functioned as a convenient headquarters for Herod’s deadly operation.

While the holy family resided in Egypt, another Herodium connection to the early life of Christ took place. After a long and terribly painful illness, Herod died. His surviving eldest son (Herod had murdered his three oldest sons), Archelaus, then buried him in Herodium at a pre-selected tomb and gave his father an elaborate funeral at the site and spared no expense, according to the Jewish historian Josephus (Jewish War, 1,673).

Israeli archeologist Ehud Netzer claimed to have found Herod’s tomb and damaged sarcophagus (stone coffin) in 2007 at Herodium, but in 2013 and 2014 other archeologists have raised doubts about the tomb and the sarcophagus. Israeli archeologists Joseph Patrich and Benjamin Arubas largely based their doubts on the modest tomb site and the unimpressive sarcophagus. They believe that the mega-maniacal Herod would have commissioned a larger tomb and a more elaborate sarcophagus.

With Herod now buried in Herodium and with Archelaus eventually ruling over much of his father’s former kingdom as an “ethnarch” (“ruler of the people”), the New Testament noted the change in political leadership (Matthew 2:19-22). The change prompted Joseph to consider a move back to Judea (perhaps back to Bethlehem itself where the family had lived for about two years), but his misgivings about a Judea under the rule of an already unpopular Archelaus and a warning in a dream led him to reconsider. The decision was a wise one. A return to Bethlehem in the “shadow of Herodium” and the nearby royal city of Jerusalem placed the holy family at potential risk.

Instead, Joseph took his family back to Nazareth in Galilee (Matthew 2:22-23). Galilee was governed by Herod Antipas, the younger brother of Archelaus. At the time, this Herodian ruler, with the title of “tetrarch” (“ruler over a fourth”), was regarded as a milder alternative to the volatile Archelaus. Located far away from the recent unpleasant associations connected to Herodium and the slaughter of the children in Bethlehem, Joseph and Mary would raise Jesus in the peaceful surroundings of Nazareth.

The recent archeological find in Herodium and the continuing dispute concerning Herod’s tomb and sarcophagus calls attention to the background story of the early life of Christ as detailed in the Gospel of Matthew. Perhaps some further archeological discoveries at Herodium will uncover additional information about the familiar nativity narrative.

I liked this article on Baptist Press so much, I pasted it here in full – because of the links between history and the Bible. It’s also reported in secular news sources like NBC News and the UK Telegraph.

When I read stories like this, it really makes me question people who think that the New Testament books were not intended to be history. I think the default view has to be that the authors intended to write history, and then we do the work to see which parts pass historical tests – i.e. – how early, how many sources, how many eyewitnesses, etc. And, do we have archaeological evidence to corroborate the narrative.
