Exceptions to a Finite Universe

by Max Andrews

The Borde-Vilenkin-Guth Theorem states that any universe, which has, on average, a rate of expansion greater 0 that system had to have a finite beginning. This would apply in any multiverse scenario as well.  There are four exceptions to the theorem.*

1. First Exception: Initial Contraction (Havg<0) … (The average rate of the Hubble expansion is less than zero)

  • Main Problem: Another problem this raises is that this requires acausal fine-tuning.  Any attempt to explain the fine-tuning apart from a fine-tuner is left bereft of any explanation.

2. Second Exception: Asymptotically static (Havg=O)

  • Main Problem: The exception is that it does not allow for an expanding or evolutionary universe.  This model cannot be true.  The best evidence and empirical observations indicate that the universe is not static; rather, it is expanding and evolving.  This might have been a great model under Newton but not since Einstein’s field equation concerning the energy-momentum of the universe.

A List of Physical Constants and Their Values

by Max Andrews

Physical constants are the values of certain spacetime, energy, and natural laws that have a set parameter that determine the structure and function of a life-permitting universe. Constants will vary in value from universe to universe in multiverse scenarios. When I refer to ‘constants’ here I mean what we presently observe as being constant. For example, the value of gravity may vary from universe to universe. The following are this universe’s constants and their values.[1]

Constants of Space and Time.

  1. Planck length (the minimum interval of space), lp = 1.62 x 10-33 cm.
  2. Planck time (the minimum interval of time), tp = 5.39 x 10-44 sec.
  3. Planck’s constant (this determines the minimum unit of energy emission), h = 6.6 x 10-34 joule seconds.
  4. Velocity of light, c = 300,000 km/sec.

An Abductive Fine-Tuning Argument

by Max Andrews

The fine-tuning argument argues that when physics and the laws of nature are expressed mathematically their values are ever so balanced in a way that permits the existence of life. I’m merely arguing that the universe is finely tuned for the essential building blocks and environments that life requires.

  1. Given the fine-tuning evidence, a life permitting universe (LPU) is very, very unlikely under the non-existence of a fine-tuner (~FT): that is, P(LPU|~FT & k) ≪ 1.
  2. Given the fine-tuning evidence, LPU is not unlikely under FT (Fine-Tuner): that is, ~P(LPU|FT & k) ≪ 1.
  3. Therefore, LPU strongly supports FT over ~FT.[1]

Defense of 1: Given the fine-tuning evidence, a life-permitting universe is very, very unlikely under the non-existence of a fine-tuner.

So what are some of the evidences for fine-tuning?

  1. Roger Penrose calculates that the odds of the special low entropy condition having come about by chance in the absence of any constraining principles is at least as small as about one in 1010^123.[2]
  2. Strong Nuclear Force (Strong nuclear force coupling constant, gs = 15)
    1. +, No hydrogen, an essential element of life
    2. -, Only hydrogen

An Abductive Thomistic Cosmological Argument

by Max Andrews

The following argument is an abductive Thomistic cosmological argument from contingency, which I presented at my recent Ratio Christi debate.

  1. There are contingent constituents to the universe.
  2. Given the contingent constituents of the universe, the existence of the universe (U) is very, very unlikely under the hypothesis that these constituents are themselves uncaused or self-caused (~Cu): that is, P(U|~Cu & k) ≪ 1.
  3. Given the contingent constituents of the universe, the existence of the universe is not unlikely under the hypothesis of a first uncaused cause (Cu): that is, ~P(U|Cu & k) ≪ 1.
  4. Therefore, U strongly supports Cu over ~Cu.

The constituents of the universe include galaxies, planets, stars, cars, humans, leptons, bosons, and other particles. For the constituents of the universe to be uncaused that would mean it is metaphysically necessary. For something to be metaphysically necessary that means that it could not have failed to exist—it exists in every possible world.

For something to be self-caused it must be simultaneously antecedent to itself to produce itself as its own effect. But this contradictory. This would be akin to the ultimate bootstrapping trick.

New Planck Satellite Data Reveals Almost Perfect Universe

by Max Andrews

I’ve been waiting for new Planck data to come in for a while now and I’ve been very excited about this. First we had COBE (Cosmic Background Explorer) that gave us the first images of the cosmic microwave background radiation approximately 380,000 years after the big bang when light became visible. This discovery led George Smoot and John Mather to receive the Nobel Prize in Physics (2006).

COBE data

Then we had the Wilkinson Microwave Anisotropy Prove (WMAP) satellite, which provided a much clearer and more defined resolution revealing a much more precise picture of the early universe.

Q&A 15: What, Exactly, IS Gravity?

by Max Andrews

Question:

Hello Max,

My name is Chad Gross and I am the director of Truthbomb Apologetics.  Brian Auten of Apologetics315 recommended that I email you with a question that I have.

My question deals with gravity and whether or not it is immaterial.  It seems to me that gravity is not composed of matter and/or energy; therefore, it is immaterial.  However, when interacting with an unbeliever on the topic on this post and he said the following:

“Without mass there would be no gravity, right? It’s true that gravity itself isn’t made of atoms, but you must admit that the material world is more than just particles. Einstein showed that matter and energy are equivalent and can transform into each other. When I talk about something being material, therefore, I’m thinking of both matter and energy.

It’s true again that gravity might not be a form of energy, since it’s just a force. Maybe gravity arises due to the nature of space and time. But without matter, there would be no space and time. So I think it’s uncontroversial to consider the physical forces to be “material.”

When I think of things that are not material, I’m thinking of spirit, or soul. God isn’t made of matter or energy, and God would still exist even without any matter or energy, right?” 

Now, I realize gravity is not immaterial in the same way that moral judgments, mathematics, logic, etc.  Here is my reply to him:

Q&A 14: Why Don’t the Laws of Nature Evolve?

by Max Andrews

Question:

Hey, Max.

I’ve just started reading Rupert Sheldrake’s The Science Delusion: Freeing The Spirit Of Enquiry and came across three questions about the laws of nature.

In Chapter 3, Sheldrake begins by saying:
“Most scientists take it for granted that the laws of nature are fixed.”
He then leads on to this question:
“If everything else evolves, why don’t the laws of nature evolve along with nature?”
The argument that he advances in the chapter involves something he calls ‘habits’, which are “a kind of memory inherent in nature”. (From what I understand, he has also advanced this within a theory of ‘morphic resonance’ in his other published works.) Putting aside his case for these ‘habits’, three questions that he poses to materialists at the end of the chapter caught my eye:
1) If the laws of nature existed before the Big Bang, and governed the Big Bang from its first instant, where were they?
2) If the laws and constants of nature all came into being at the moment of the Big Bang, how does the universe remember them? Where are they ‘imprinted’?
3) How do you know that the laws of nature are fixed and not evolutionary?
Although I can hear the materialists cry that these questions are not even wrong, I wondered what you thought about them.
Best Wishes,
Mark Hawker (UK)

Higgs Boson Calculations Indicate a Finite Lifespan for the Universe

by Max Andrews

Screen Shot 2013-02-28 at 7.46.19 PMReblogged from Irene Klotz with Yahoo News.

Scientists are still sorting out the details of last year’s discovery of the Higgs boson particle, but add up the numbers and it’s not looking good for the future of the universe, scientists said Monday [Feb. 18].

“If you use all the physics that we know now and you do what you think is a straightforward calculation, it’s bad news,” Joseph Lykken, a theoretical physicist with the Fermi National Accelerator Laboratory in Batavia, Illinois, told reporters.

Lykeen spoke before presenting his research at the American Association for the Advancement of Science meeting in Boston.

“It may be that the universe we live in is inherently unstable and at some point billions of years from now it’s all going to get wiped out,” said Lykken, who is also on the science team at Europe’s Large Hadron Collider, or LHC, the world’s largest and highest-energy particle accelerator.

Max Tegmark on Religion and Science

by Max Andrews

The bulk of my graduate research is focused on the work and thought of Max Tegmark, an MIT astrophysicist/cosmologist, who’s responsible for a tremendous contribution to multiverse models. In honor of Charles Darwin’s 204th birthday he did an article for the Huffington Post, “Celebrating Darwin: Religion and Science are Closer Than You Think.” There are some very interesting survey results regarding faith and conflict between evolution and big bang cosmology.

So is there a conflict between science and religion? The religious organizations representing most Americans clearly don’t think so. Interestingly, the science organizations representing most American scientists don’t think so either: For example, the American Association for the Advancement of Science states that science and religion “live together quite comfortably, including in the minds of many scientists.” This shows that the main divide in the U.S. origins debate isn’t between science and religion, but between a small fundamentalist minority and mainstream religious communities who embrace science.
