New discovery confirms Big Bang, and is direct evidence for cosmic inflation

From the UK Telegraph.

Excerpt:

Space-time ripples left over from the Big Bang have been picked up for the first time by Harvard scientists.

Astrophysicists have been hunting for ‘primordial gravitational waves’ since they were predicted by Albert Einstein’s theory of general relativity in 1916.

Today, after days of rumour and speculation, scientists from the Harvard-Smithsonian Centre announced they had recorded the first direct evidence of gravitational waves rippling through the infant universe.

“The implications for this detection stagger the mind,” said project leader Jamie Bock. “We are measuring a signal that comes from the dawn of time.”

Our universe burst into existence 13.8 billion years ago. Fractions of a second later, space and time were created, expanding exponentially in an episode known as ‘inflation’.

It was theorized that inflation should also produce gravitational waves – ripples in space-time which spread throughout the universe.

“Think of the ripples you see when you throw a stone into a pond,” said Professor Martin Hendry of the department of Physics and Astronomy at the Univesity of Glasgow.

“But these aren’t ripples on the surface of the water, they are gravitational waves emitted billions of years ago, rippling through the fabric of space and time itself, in the universe’s earliest moments.

“We always suspected they were still washing about but we haven’t been able to detect them.

[…]The signal was found using a specialised telescope called Bicep (Background Imaging of Cosmic Extragalactic Polarization) at the South Pole.

It scans the sky at microwave frequencies, where it picks up light energy from slightly after the Big Bang – around 380,000 years later. Scientists have been searching for tiny ripples in this light which would show it is being slightly stretched by gravitational waves.

We have had a string of solid, recent scientific discoveries that support the idea that the universe came into existence at some point in the finite past, as follows:

  • Einstein’s theory of general relativity, and the scientific confirmation of its accuracy
  • measurements of the cosmic microwave background radiation
  • red-shifting of light from galaxies moving away from us
  • radioactive element abundance predictions (from supernovae)
  • helium/hydrogen abundance predictions (nuclear fusion)
  • star formation and stellar lifecycle theories
  • the second law of thermodynamics

This new discovery is building on #2 above – the cosmic microwave background radiation.

What came into being at the moment of creation?

As the article states, space was created and time began at the first moment.

  1. There was no space causally prior to the universe beginning to exist
  2. There was no time causally prior to the universe beginning to exist
  3. There was no matter causally prior to the universe beginning to exist

All of these things began to exist at the first moment.

What can we infer about the cause?

So, space, time, and matter began to exist. What could have caused them to begin to exist?

  1. Whatever causes the universe to appear is not inside of space, because there was no space causally prior to the creation event. The cause must therefore be non-physical, because physical things exist in space.
  2. Whatever causes the universe to appear is not bound by time (temporal). It never began to exist. There was no passage of time causally prior to the big bang, so the cause of the universe did not come into being. The cause existed eternally.
  3. And the cause is not material. All the matter in the universe came into being at the first moment. Whatever caused the universe to begin to exist cannot have been matter, because there was no matter causally prior to the big bang.

So what could the cause be? Dr. William Lane Craig notes that we are only familiar with two kinds of non-material realities:

  1. Abstract objects, like numbers, sets and mathematical relations
  2. Minds, like your own mind

Now, abstract objects don’t cause of any effects in nature. But we are very familiar with the causal capabilities of our own minds – just raise your own arm and see! So, by process of elimination, we are left with a mind as the cause of the universe. As Sherlock Holmes says, “When you have eliminated the impossible, whatever remains, however improbable, must be the truth.“

This cause created the entire physical universe. The cause of this event is therefore supernatural, because it brings nature into being and is not inside of nature itself. The cause of the universe violates the law of conservation of matter is therefore a miracle. And when we do our science, we find evidence of it.

Bible study: on the importance of truth in religion

3 Comments

Here’s an interesting passage of the Bible. What do you all think the practical value of this passage is?

1 In the second year of his reign, Nebuchadnezzar had dreams; his mind was troubled and he could not sleep.

2 So the king summoned the magicians, enchanters, sorcerers and astrologers to tell him what he had dreamed. When they came in and stood before the king,

3 he said to them, “I have had a dream that troubles me and I want to know what it means.”

4 Then the astrologers answered the king, “May the king live forever! Tell your servants the dream, and we will interpret it.”

5 The king replied to the astrologers, “This is what I have firmly decided: If you do not tell me what my dream was and interpret it, I will have you cut into pieces and your houses turned into piles of rubble.

6 But if you tell me the dream and explain it, you will receive from me gifts and rewards and great honor. So tell me the dream and interpret it for me.”

7 Once more they replied, “Let the king tell his servants the dream, and we will interpret it.”

8 Then the king answered, “I am certain that you are trying to gain time, because you realize that this is what I have firmly decided:

9 If you do not tell me the dream, there is only one penalty for you. You have conspired to tell me misleading and wicked things, hoping the situation will change. So then, tell me the dream, and I will know that you can interpret it for me.”

10 The astrologers answered the king, “There is no one on earth who can do what the king asks! No king, however great and mighty, has ever asked such a thing of any magician or enchanter or astrologer.

11 What the king asks is too difficult. No one can reveal it to the king except the gods, and they do not live among humans.”

12 This made the king so angry and furious that he ordered the execution of all the wise men of Babylon.

13 So the decree was issued to put the wise men to death, and men were sent to look for Daniel and his friends to put them to death.

14 When Arioch, the commander of the king’s guard, had gone out to put to death the wise men of Babylon, Daniel spoke to him with wisdom and tact.

15 He asked the king’s officer, “Why did the king issue such a harsh decree?” Arioch then explained the matter to Daniel.

16 At this, Daniel went in to the king and asked for time, so that he might interpret the dream for him.

17 Then Daniel returned to his house and explained the matter to his friends Hananiah, Mishael and Azariah.

18 He urged them to plead for mercy from the God of heaven concerning this mystery, so that he and his friends might not be executed with the rest of the wise men of Babylon.

19 During the night the mystery was revealed to Daniel in a vision. Then Daniel praised the God of heaven

20 and said:

“Praise be to the name of God for ever and ever;
wisdom and power are his.

21 He changes times and seasons;
he deposes kings and raises up others.
He gives wisdom to the wise
and knowledge to the discerning.

22 He reveals deep and hidden things;
he knows what lies in darkness,
and light dwells with him.

23 I thank and praise you, God of my ancestors:
You have given me wisdom and power,
you have made known to me what we asked of you,
you have made known to us the dream of the king.”

24Then Daniel went to Arioch, whom the king had appointed to execute the wise men of Babylon, and said to him, “Do not execute the wise men of Babylon. Take me to the king, and I will interpret his dream for him.”

25 Arioch took Daniel to the king at once and said, “I have found a man among the exiles from Judah who can tell the king what his dream means.”

26 The king asked Daniel (also called Belteshazzar), “Are you able to tell me what I saw in my dream and interpret it?”

27 Daniel replied, “No wise man, enchanter, magician or diviner can explain to the king the mystery he has asked about,

28 but there is a God in heaven who reveals mysteries. He has shown King Nebuchadnezzar what will happen in days to come. Your dream and the visions that passed through your mind as you were lying in bed are these:

29 “As Your Majesty was lying there, your mind turned to things to come, and the revealer of mysteries showed you what is going to happen.

30 As for me, this mystery has been revealed to me, not because I have greater wisdom than anyone else alive, but so that Your Majesty may know the interpretation and that you may understand what went through your mind.

This passage is interesting to me because it shows the kind of attitude that God answers. The King in this passage was tired of hearing man-made stories from his servants – stories that were undoubtedly influenced by the servants desire to survive the King’s wrath. The servants would only have told the King things that were vague and happy, so that they could never be proved wrong or found to be judgmental or offensive. But the King was tired of that. He wanted someone with authority to tell him the truth about the way the world was.

In the rest of the chapter, Daniel interprets the dream, and concludes by saying this: “The great God has shown the king what will take place in the future. The dream is true and its interpretation is trustworthy.”. The King replies: “Surely your God is the God of gods and the Lord of kings and a revealer of mysteries, for you were able to reveal this mystery.”

I think it is is going to be difficult for Christians living today to be able to tell people their dreams like that. But what we can do is talk about God’s miracles as revealed by science and history. We can study astrophysics, biochemistry and history and we can explain what God did in creating and fine-tuning the universe for life, in sequencing amino acids into functioning proteins, in creating brand new body plans in the Cambrian explosion, in raising Jesus from the dead as a matter of historical record, and so on. We have to show how great God is to people who do not even think he exists, and without assuming that they believe in the Bible.

There are still people out there like the King who are looking for someone who can speak to them with authority. All it takes from us is a little studying, and we can be like Daniel, too. But we have to know what God has done from science and history, and speak with authority about how we can know that God has acted supernaturally. Authority to speak comes from having knowledge about what we are talking about, and knowledge comes from studying and debating with people we disagree with. Nebuchadnezzar  was not a believer in the God of Israel, but he was still interested in truth. That won’t always be the case, but it is the case for some people.

Democrats in California want to pass laws to penalize Asians

6 Comments

Basically, the Democrats in California want to pass an affirmative action bill, which would penalize overachievers. Asians tend to outperform other races in academics, so they are always the losers when academic criteria are minimized in favor of racial criteria for college admissions.

Here’s an article from National Review, sent to me by Letitia.

Excerpt:

The California state legislature was on the verge of approving a referendum to restore the consideration of race and ethnicity in admissions to state universities.

[…]What both sides of the bimodal Asian immigration population have in common is that their children do uncommonly well in school. They are represented in California’s much-admired universities in far larger numbers than their share of the population would suggest: Asians compose 14 percent of California’s population but 37 percent of the undergraduates at its state universities. They make up about 40 percent of the students at UCLA, 43 percent of the students at Berkeley, half the students at UC San Diego, and more than half of the students at UC Irvine. A relatively small minority, they compose the largest single ethnic group on California university campuses (at least as California defines “ethnic group”).

[…]Liberals talk a great deal of mindless rot about what they like to call “privilege,” the supposedly omnipresent advantages that accrue to the white, the male, the heterosexual, those whose sense of self is more or less congruent with their biological genitals, etc. But it is worth keeping in mind that progressive social-engineering programs such as the use of racial criteria in university admissions do not hurt only hurt well-off white people sporting penises. (Not that we should shortchange the interests of well-off white penis-sporters.) They also hurt poor people and immigrants, in this case a group of immigrants that we as a country should count ourselves lucky to have. It is important to remember why race-based admissions are such an important issue for progressives: The Left lives in the public schools, which do a terrible job of teaching black, Hispanic, and poor students, who consequently show up in embarrassingly small proportions at elite institutions. Asian students, on the other hand, do a tremendous amount of work outside of school, spending ten times as much time as non-Asian students do on organized non-school activities ranging from music lessons to tutoring to test-preparation courses. That is true across the economic spectrum: Working-class Asian immigrant families in Queens send their children to tutoring sessions and piano lessons at a much higher rate than does the non-Asian population, even though the relative financial sacrifices necessary for them to do so are heavy.

For that, California’s professional race hustlers, and their allies across the country, would see them punished.

So, here is another case where the party that talks a lot about racism and race is actually the one that is opposed to Asians getting ahead. My view is that if Asians have the strong families that produce high achievers, then let them be 40% of the students at the university. Maybe then people of other races will get the message that they need to focus more on raising children who can compete. Follow the rules and you won’t be poor: finish high school, get jobs, get married, have children, don’t get divorced. If you follow those rules, you will not be poor, and your children will outperform you.
