Stephen Hawking and imaginary time

Update 14/03/2018 Professor Stephen Hawking died today. See his obituary here. From all I have read he remained an ardent atheist his whole life. And he never really understood the worldview issue in cosmology and the origin of the universe. This proves that even very smart people can get it wrong. Nevertheless he gave us much to ponder, debate and learn. 

What is imaginary time? I don’t mean the time you spend day-dreaming but the concept in physics, promoted by theoretical physicist Stephen Hawking. It is used in some quantum mechanics and special relativity theory. Imaginary time is where the usual time dimension undergoes a Wick rotation (a phase rotation)1 so that its coordinates are multiplied by the imaginary number the square root of -1, represented by the symbol i. In such a situation time theoretically behaves like a spatial dimension.

Hawking wrote:2

“One might think this means that imaginary numbers are just a mathematical game having nothing to do with the real world. From the viewpoint of positivist philosophy, however, one cannot determine what is real. All one can do is find which mathematical models describe the universe we live in. It turns out that a mathematical model involving imaginary time predicts not only effects we have already observed but also effects we have not been able to measure yet nevertheless believe in for other reasons. So what is real and what is imaginary? Is the distinction just in our minds?” (emphasis added)

Positivism is the philosophy that we cannot determine what is real, but we can only propose hypotheses and test those against what we observe. Hawking is an atheist—an anti-theist—and has spent some time attempting to show that the Creator is unneeded in the universe.

Hawking claims that imaginary time is as real as real time, only that it is travelling in a different direction.3 He claims that ‘before’ the big bang time was imaginary and thus there was no time. Imaginary time may have “always existed” he said, but because we have no idea of what the laws of physics were ‘before’ the big bang, and there is no way to measure what happened ‘before’ the big bang, hence there is no point including time back then in a discussion of our universe.

Did aliens hack the Voyager 2 space probe in 2010?

I don’t know how I missed this news item back from 2010! Then NASA reported a single bit-flip error occurred in Voyager 2’s software code used to communicate with Earth. That sounds pretty mundane in today’s IT savvy world where we are all used to software errors and corrupt code.

Artist’s concept of Voyager 2 in flight.

But sometime the corruption of code is due to deliberate interference. Hackers hack into computers everyday for fun or more nefarious reasons. In this instance several scientists suggested that the on-board computer was hacked by an alien race (from another star system) who were trying to communicate with us.

But note the Voyager 2 space craft at that time was nearly about to cross over into what we would call interstellar space. It was about to leave the solar system in 2010 at a distance of 90 times the distance between the sun and the earth. That is about 8.6 billion miles or about 14 billion kms. That means it takes a light signal nearly 13 hours, travelling at nearly 300,000 km/s, to travel from the space probe to Earth. For NASA to send and receive a signal that would take twice that time, nearly 26 hours. It is certainly at a distance where one can easily discount any Earth based hacker.

The following is excerpted an online news item from 6 years ago and is typical of the several available.1

NASA space probe Voyager 2, which left earth 33 years ago, may have been hijacked by aliens who are now trying to make contact with earth according to a German academic.

The craft, which is 8.6 billion miles from earth on the very edge of the solar system, has been sending back data ever since it was launched – until last month when it briefly stopped transmitting before starting to send strange messages that scientists cannot decipher.

German academic Hartwig Hausdorf believes the change could be down to extraterrestrials. He says that because the rest of the spacecraft is still working normally there may be more to the cryptic messages than meets the eye.

“It seems almost as if someone has reprogrammed or hijacked the probe,” he told German newspaper Bild. “Thus perhaps we do not yet know the whole truth.”

NASA was much more circumspect stating that they believe it was due to this one corrupt bit of code. That may have occurred due to radiation in space or impact by a highly energetic particle which flipped the bit.

An eternal quantum potential or an eternal Creator God

JGH1As a teenager I co-authored a book comparing the competing cosmologies in 1968. They were the Big Bang Theory (BBT) and the Steady State Theory (SST). Even though the discovery of the cosmic microwave background (CMB) radiation provided a big boost to big bang theories at that time, I preferred the SST because it had no origin in time. You see, I was an atheist then and I reasoned that if the Universe had no beginning then it didn’t need a Creator and thus I had no God that I needed to obey.

The fact that the BBT has an origin in time—a unique past boundary—has been particularly vexing for the atheist believers in that cosmogony. Using various approaches the BB theorists have been trying to eliminate the beginning, by replacing the Creator with an eternal quantum potential, which existed for eternity past, and then 13.8 billion years ago exploded into the big bang universe, … or, so they say. For now though, they are stuck with the universal origin in a singularity, which in itself has led them to worshipping the Universe itself.

The explanation given in the Bible I now find so much more satisfying. Any cosmogony, which attempts to correctly describe real history, must be consistent with and follow not only the biblical time scale but also follow the sequence of events in the Genesis account. I present a very brief summary of a few biblical creationist models. These models acknowledge the eternal Creator God as the source of everything in the Universe.

Piercing the ‘Darkness’

—The bankruptcy of big-bang thinking and its ‘dark’ fudge factors

JGH1Six important questions are asked in regards to the alleged big bang origin of the Universe? These questions highlight the bankruptcy of big bang thinking, about the origin of the universe that needs numerous fudge factors.

Embracing the ‘darkness’ has led man to develop unprovable fudge factors to plug the holes in his failed theory. I deal with each of these:

  1. Where did the Universe come from?
  2. How did nothing explode?
  3. How did stars and galaxies form?
  4. Why does CMB ‘light’ cast no shadows?
  5. Why the ‘Axis of Evil’?
  6. What about expansion of space?

…. 14 more problems are listed but not discussed in any detail.

Six major fudge factors are highlighted as a result but there are many more. The big bang needs these unverifiable fudge factors; so why hasn’t it been discarded? The answer is simple. The alternative, for the atheist–a Creator God–is unbearable, and for the compromised theist or deist, who accepts a big bang origin for the universe, the Creator as described by a straightforward reading of the Bible, is unbearable.

The big bang is pagan philosophy

Is the big bang evolution story of the Universe really science? And is the big bang a valid starting point to argue that science supports the biblical narrative history from the Genesis account and elsewhere? Can we consider a big bang creation in our apologetics?

BB evolution

Foundations for our apologetics

In apologetics1 we are engaged in a spiritual war, which we fight on a daily basis. We win some battles, we lose some, but we know that the war will eventually be won by God. He has told us that fact. Often however our comrades in arms, i.e. other Christians, may themselves not clearly see the enemy’s tactics. That does not mean they cannot see the enemy but may be they are too close in battle to see the whole war.

Faithful are the wounds of a friend; but the kisses of an enemy are deceitful. Proverbs 27:6 (KJV)

Sometimes we must criticise what our friends have said in an effort to prevent the enemy from developing a breach in the wall of truth and eventually destroying the foundations. In this case our friends are our fellow Christians who have gotten off the track by absorbing too much of the pagan culture in which they live.

Life in the Universe is the ultimate miracle

Life in the universe is rare, so rare in fact, I would wager that sentient life is only found on planet Earth. For nearly 50 years the collection of telescopes and scientists under the umbrella name of the Search for Extraterrestrial Intelligence (SETI) have searched among the wavelengths of a myriad stars in search of a radio signal, any signal, from intelligent life. But have they detected any? Apart from detecting the odd microwave oven in their own establishment,1 no is the answer.

In 2013 Space.com headlines with “Alien Life May Be Rare Across the Universe“2 but on July 23, 2015 NASA announced the discovery of Earth 2.0 with a headline on Space.com of “NASA Finds Closest Earth Twin Yet in Haul of 500 Alien Planets.”3

It is all over the news with a host of pictures of Earth 2.0. But wait, they are only artists’ conceptions.”4  One such drawing is reproduced here.

The report is that NASA found a near twin to Earth named Kepler-452b. It orbits its sun every 385 days, is 60 per cent larger in diameter than Earth, has a mass probably 5 times that of Earth and is located about 1,400 light years away. It’s a big deal! But why?

An eternal big bang universe

As a high school student, at a time when I was an atheist, I co-authored a book reviewing the various cosmological models that were discussed in the scientific literature in 1968. That was three years after the discovery of the cosmic microwave background (CMB) radiation, and the Big Bang Theory had just made a big leap forward in front of its competitor at the time, the Steady State Theory.

In our book—which by the way won us second prize in a Western Australian state-wide science competition—we outlined the two competing models. The Big Bang Theory at that time had three distinct forms:

  1. the cycloidal model, which would collapse back into a big crunch (and bounce out of the singularity cyclically) because the matter density of the universe was too great to resist the inevitable re-collapse (a finite closed universe);
  2. the coasting model, which had just the right amount of matter for an infinite universe that is neither accelerating nor decelerating in its expansion, continually expanding but never collapsing (an open infinite universe); and
  3. the hyperbolic model, an accelerating expanding universe, low matter density but also driven apart by a cosmological constant term (an open and infinite universe).

The most favoured of the three was the closed cycloidal model with a matter density greater than critical so it had to collapse back in a big crunch. Nowadays it is the accelerating infinite (open) universe, which is spatially flat due to dark matter and dark energy content.

On reviewing these models, and even knowing that the CMB discovery favoured these as a prediction of the big bang theorists, particularly George Gamow, I personally favoured the Steady State Theory. The Steady State Theory really had only one model, which was an infinite universe that was eternal both into the past and into the future. It had no beginning and no ending.

The lecture: 8 reasons why evolution is foolish

Synopsis:

8 reasons are presented that make evolution an impossible idea. The term evolution is used in the general sense applying to the universe beginning at the big bang, and including cosmic evolution of stars and galaxies, the solar system and Earth, and the origin of life and biological evolution.

The questions are taken from the cosmos, from geology of the planet Earth and from biology. The reasons that make evolution foolish as a viable scientific theory are posed as the lack of any reasonable answer to 8 questions:

Where did the Universe come from?
How did nothing explode?
How did stars and galaxies form?
How come all rocks dated with Carbon-14 give ‘absolute ages’ less than 56,000 yrs?
How do you determine the absolute age of a fossil?
Why hasn’t evolution been observed?
How does specific complex coded information in DNA arise by chance?
How did life arise from non-living chemicals by random chance?

See my article 8 REASONS WHY EVOLUTION IS FOOLISH.  Note the questions and my answers also at the end of the web article. You can find a pdf tract of the same title in English or other languages under Downloads on the front page.

This is a lecture delivered at the University of Adelaide on June 6th, 2014. I presented the lecture to an audience of about 55 and spoke on the topic for about 60 minutes presenting my 8 reasons via 8 questions which, so far, have not been answered by evolutionists. Following the lecture we had about 40 minutes of Q&A. The lecture was attended by an atheist group who attempted to catch me with ‘straw men’ and misdirected questions, see: ATHEISTS TURN OUT TO STRIKE AGAINST CREATIONISM AND THE SUPERNATURAL.

The singularity—a ‘Dark’ beginning

Did the universe form spontaneously from nothing?

“The universe burst into something from absolutely nothing – zero, nada. And as it got bigger, it became filled with even more stuff that came from absolutely nowhere. How is that possible? Ask Alan Guth. His theory of inflation helps explain everything.”—front cover of the April 2002 issue of Discover magazine

First years
Figure 1: The first several hundred million years after the big bang is when the universe was in its Dark Ages. No ionized hydrogen meant that no sources of light were available during that period. Larger image available from http://www.astro.caltech.edu/~george/reion/.

“Spontaneous creation of the universe from nothing”1 is the title of a 2014 paper authored by He, Gao and Cai, published in the American Physical Society journal Physical Review D, one of America’s most prestigious journals dealing with physical theory. It purports to outline a so-called mathematical proof that the universe did indeed burst into something from nothing.

Atheists turn out to strike against creationism and the supernatural

On Friday June 6th, I presented a lecture at the University of Adelaide entitled “8 Reasons Why Evolution is Foolish” to an audience of about 55, filling about half of the seating in a small lecture theatre. I spoke on the topic for about 60 minutes presenting my 8 reasons via 8 questions which, so far, have not been answered by evolutionists. Following the lecture we had about 40 minutes of Q&A. The video of the lecture is here.

Atheist commentAn organised group of atheists turned out to “strike a blow for science against creationism and the supernatural” by taking me on. That is what they claimed on their website.1 See left excerpt.

There were about 10 members of some atheist club, who peppered themselves through the audience. After the event one guy identified himself as president of some atheist club, so it is clear they came with an action plan. I had been forewarned that something like this might happen as one contact told me that there had been a lot of activity on a university-connected FB page about this event. But their arguments and the questions they put to me in the Q&A were a total failure.
