Controversial Cosmologist Fred Hoyle Dies At 86
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.

Also interesting is how Darwin recanted his life's work on his deathbed, finding it all to be complete non-sense.
It would be interesting if it weren't for the fact that it never happened.

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.

our knowledge of physics actually breaks down as we theorize back to the "Big Bang"
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.)
