Controversial Cosmologist Fred Hoyle Dies At 86 203
MikeCamel writes: "The BBC announced today that Fred Hoyle, astronomer, science populariser and science fiction writer, died yesterday, aged 86. He is best known for having coined the phrase 'Big Bang,' though he was actually an opponent of the idea, and advocated the 'steady state' theory. He also believed that life didn't start on Earth, but that we were 'seeded' from outer space."
farrellj adds: "Hoyle was famous for a number of things, inventing the term 'Big Bang,' figuring out how stars create the heavier elements, and his most controversial, the idea that the seeds of life on earth came from space. He was also a noted Science Fiction writer, with many books, sometimes co-authored with his son, Geoffrey. We have lost one of the more original thinkers in the field of Astrophysics.

I guess it all depends on your idea of a "good scientific theory".
Obviously, you can't mean "any theory that was later proved to be incorrect or inadequate". I'm guessing that you mean something along the lines of "theories that were developed before the advent of - or without recourse to - the modern idea of the 'scientific method'".
Personally, I think the "phlogiston" theory was pretty good for its time - it explained a certain phenomena in a way that agreed with the current paradigm.
Oh. I get it. The phlogiston theory was bad because the "scientist" who proposed it was not visionary enough to first propose a paradigm shift that would allow a different, correct theory to become evident. By the same token, Fred Hoyle was a good scientist because his theories were almost always preceded by a paradigm shift that was not adopted by the rest of the scientific community.
I guess that in order to properly judge Newtonian physics, we should first determine if that theory required a sufficiently radical paradigm shift before it could be proposed.
The same principle applies to creationism, I suppose.

In this "enlightened" age of après-truth, it is not fashionable to talk of right and wrong answers; people prefer, rather, to talk about "different points of view." Nevertheless, nature is what it is, without regard to what point of view we might have on the matter.

I'm sorry, but that's been my experience after spending thousands of hours debating Creationism, Evolution, the validity of the Bible, and the utility of the Scientific Method. Religious people tend to play fast and loose with the facts much more consistently than non-religious people.
I think that it has a lot to do with perceived stakes. The scientist/atheist has only some pride at stake -- he doesn't believe in the supernatural, so the discussion for him can remain at an "academic level." Hell, most scientific types I know would be ecstatic to discover proof of the supernatural. I, personally, would give everything I had to learn that the promises of religion were true. Growing old and dying sucks -- who doesn't want to live forever in the light of a loving and sheltering God?
The religious person, on the other hand, has everything at stake. This person is defending the eternity of his soul. He has everything to lose if the scientific/atheistic viewpoint were to somehow win the day. Psychologically, he's in a complete panic when cornered. Everything he wants: that invisible buddy in the sky, everlasting life, justification for his whole existence - is bound up in his beliefs. He has to do absolutely everything to protect those beliefs for himself and in an attempt to "save" those around him. Lying is a small sacrifice to make when you're talking about saving someone else's soul, right?
Not to mention my irritation that the terms are used like they are somehow mutually exclusive.
Think about the ramifications of the word "supernatural", and then think about the Scientist's adherence to methods of uncovering the secrets of our "natural" world. The supernatural by definition is beyond "natural". It flies in the face of everything that science has uncovered so far about our universe. Why? Because there has been no consistently credible evidence for the supernatural. The supernatural are things that can never seem to be witnessed by the credible or proven in a laboratory. Now, that's not to say that I haven't known scientific types who also have unprovable religious beliefs. They definitely do exist. Usually, though, it's sort of an odd blind spot that the Scientist allows to exist. He'll be perfectly rational about the known universe, except when confronting his own religious beliefs. Ah well, no one is perfect.
Another data point to note is the percentage of scientists who are agnostic or atheistic. I think that number was around 80% the last time I saw the poll in Scientific American.

Hoyle spent decades studying the universe and life in it, and became convinced that life on earth could not have happened solely through "the blind forces of nature". Lecturing at the California Institute of Technology he once explained:
"The big problem in biology isn't so much the rather crude fact that a protein consists of a chain of amino acids linked together in a certain way, but that the explicit ordering of the amino acids endows the chain with remarkable properties . . . If amino acids were linked at random, there would be a vast number of arrangements that would be useless in serving the purposes of a living cell. When you consider that a typical enzyme has a chain of perhaps 200 links and that there are 20 possibilities for each link, it's easy to see that the number of useless arrangements is enormous, more than the number of atoms in all the galaxies visible in the largest telescopes. This is for one enzyme, and there are upwards of 2000 of them, mainly serving very different purposes. So how did the situation get to where we find it to be?"
Hoyle added: "Rather than accept the fantastically small probability of life having arisen through the blind forces of nature, it seemed better to suppose that the origin of life was a deliberate intellectual act."
Hoyle left us with some fascinating intellectual gems to consider. As our knowledge of biological complexity increases, more and more educated people who understand these complexities are in agreement with his observations.

In an enzyme, only a few of the amino acids are active, and most of the others only serve as a superstructure, being somewhat interchangeable.
Our proteins have higher variations than what was previously thought, and in a single species may be found in dozens of similar yet diferrent forms.
Some hypothesis are that self-reproducing RNA could have been the beginning of life, not proteins and DNA.
Lastly, many enzymes are just versions of older proteins, that have evolved into having a completely different role, and yet come from the same basics. This also reduces the amounts of different amino acids combinations needed before life was possible.

First Evidence Of Life Coming From Space Reported
Evidence of living bacterial cells entering the Earth's upper atmosphere from space has come from a joint project involving Indian and UK scientists. The first positive identification of extraterrestrial microbial life was reported on Sunday (July 29) at the Astrobiology session of the 46th Annual SPIE meeting in San Diego, by Professor Chandra Wickramasinghe of Cardiff University in Wales. He spoke on behalf of an international team led by Professor Jayant Narlikar, Director of the Inter-Universities Center for Astronomy and Astrophysics in Pune, India.
Samples of stratospheric air were collected on January 21 under the most stringent aseptic conditions by Indian scientists using the Indian Space Research Organisation's (ISRO) cryogenic sampler payload flown on balloons from the Tata Institute Balloon Launching facility in Hyderabad.
Part of the samples sent to Cardiff were analyzed by a team at Cardiff University led by Professor David Lloyd, assisted by Melanie Harris.
Commenting on the results, Professor Wickramasinghe said, "There is now unambiguous evidence for the presence of clumps of living cells in air samples from as high as 41 kilometers, well above the local tropopause (16 km), above which no air from lower down would normally be transported."
The detection was made using a fluorescent cyanine dye which is only taken up by the membranes of living cells. The variation with height of the distribution of such cells indicates strongly that the clumps of bacterial cells are falling from space.
The daily input of such biological material is provisionally estimated as about one third of a ton over the entire planet.
This new evidence provides strong support for the Panspermia theory of Sir Fred Hoyle and Chandra Wickramasinghe.
"We have argued for more than two decades that terrestrial life was brought down to Earth by comets and that cometary material containing microorganisms must still be reaching us in large quantities," Professor Wickramasinghe said.
Cardiff University is home to the UK's first Center for Astrobiology, which provides the UK with a facility to contribute to space missions probing for life on solar system bodies. The Center is a joint initiative between the University and the University of Wales College of Medicine.
The Center combines research interests in astronomy and molecular cell biology to throw light on the emergence and development of life in the cosmos and planetary bodies. The work of the Center will also provide information essential for the emergent discipline of space medicine.
Cardiff University has a history of service to Wales and the world which dates from its foundation by Royal Charter in 1883. Today, independent government assessments recognize the University as one of Britain's leading research and teaching universities.

For Wickramasinghe to look at that evidence and view it as support for not only the assertion that living organisms are carried to Earth on comets, but also for the assertion that these organisms are the origin for life on earth, is a stunning example of crackpottery.
We found these organisms in the atmosphere. Where did they come from? Somewhere down below, where we observe an abundance of life in a multitude of forms, or from space?

The distances are not even close. The brightest star in Orion's belt is the middle star, but the largest Giza pyramid is on the end. The kink's angle is off by over 20%. Bauval made up most of this. As a scientist, you might check such things.

The Old Kingdom ended long after the Irish tree trauma--c. 2200 BC. The likely cause was extremely low Nile flood levels. And there is no evidence from ice cores to support your claim of high dust levels. You just made up most of this.
Wickramasinghe apparently did not reply. It seems clear that the Daily Mail article Wickramasinghe wrote was fraudulent.
For me, once someone has done something fraudulent, I become suspicious of all their other work. If you consider the prestige that Wickramasinghe might garner from his panspermia claims, there is all the more reason to be suspicious.

Wild theories, bad science (Score:2)
Take a look at any Creationist/Evolutionist debate. The Creationists always quote Fred Hoyle, because the dumbass didn't really separate his wild speculation from his more grounded theories. Creationists use the words of a "noted astronomer" to advance their own non-scientific agenda.
Every time I read someone about to quote Fred Hoyle, I cringe, knowing that I'm about to sit through some bullshit foisted on us through the careless attitude toward science of one of "our own".
Re:Wild theories, bad science (Score:1)
Also, as a scientist, it can sometimes be hard, except in detailed writing, to seperate my speculations from detailed theory...there is a spectrum of thought between the two.
At the time Hoyle coined "Big Bang" as a derogatory term for that theory, the BB theory was, frankly, pretty far out there. It had General Relativity backing it, which was pretty good, but observationally it was not as strongly supported as today.
You have to remember that what makes a speculation into a well established theory is how well it makes predictions. The BB theory makes detailed predictions as to what will be seen, and so far, it has stood the test of time.
Just because some jokers take Hoyle's quotes out of context (by assuming something he said 30 years ago was his viewpoint today) doesn't make Hoyle a bad scientist.
After all, I hate to think that I will be held accountable for all my theories I espouse today 30 years from now.

New interstellar ice supports Hoyle's Panspermia (Score:2, Interesting)
One of his major theories was that complex organic matter drifted through and evolved in interstellar space. It's long been seen that organic matter could form huge clouds, but it was always an open question as to how it could possibly "evolve".
But the recent discovery of exotic forms of ice that possess many of the properties of liquid water rather than the usual, crystalline solid properties of earth-bound ice make this possible. Evolution happens *much* more slowly in interstellar space and within comet cores, but now the discovery of this new ice makes it probably, even likely, that exotic forms of space-bound life exist and thrive.

As a side note, he was originally a campaigner against the singularity theory of universal origins (which he derisively coined the "Big Bang Theory"). It was the "all or nothing" part of it that most offended him. And the insistence on bounded, finite time.
He was more all about a continuous and random creation of matter in what he termed "interstitial spaces".
Nowadays, the hottest theories of cosmology involve quantum foam expansion, oscillations, and string loops spitting off random particles. Kind of a weird synthesis of the two. I guess we're in the middle of a paradigm shift.
In another generation, the debate about Bing Bang versus Steady State will seem as quaint and alien as the argument over which theory could best explain diseases: Humoral, Miasmatic, Contagia, or Germ.

Fred Hoyle was the guy who was bold enough to predict a resonance oxygen burning step in the thermonuclear cycle of stars when everybody else was saying its impossible. Willy Fowler found it, and both wrote a paper on it, solving one of the greatest problem in stellar physics.
Fowler got the Nobel, Hoyle did not. The problem is that Hoyle was a proponent of the "life from space" idea, and the Nobel Committee was embarrassed to give him that.
Shame. Shame on the Noble Committee.

It certainly was known before "A Brief Theory of Time". What happens is that, as we work backwards in time, trying to figure out what the universe was at certain points in time, we get to a point which is 1.e-43 second away from the Big Bang, and we find that all "laws" break down at that point. We just can't describe what happened in that first fraction of a second; there's no way to get at it. Another way of thinking of it is to say that the "laws" of physics were being created in that first fraction of a second. The analogy is pretty bad, but what is important to realise is that it's not a function dependent on our inability to measure more accurately, or see farther with a bigger telescope, or test with finer granularity...all our laws simply stop working at that point.
A few years ago, Fred Hoyle (along with a couple of other chaps, whose names escape me) postulated a new variation on the steady-state model, known as the quasi-steady-state model or QSSM. This basically says you have periods of rest and then periods of activity in the creation of the universe, perhaps as many as six or seven. Quite seriously, it actually sounds a lot like "On the nth day, God created...and night passed...". (Cue flamebait/troll mods -- but it really does.)
