I thought you'd enjoy yourself. But, again, before you seriously consider panspermia, remember 1. That the probabilities that I spoke of on p. 151 hold true on ANY planet in the universe. The point is that it's a friggin miracle that there is life on this planet much less any other. In my opinion we know enough to say that it is a practical impossiblity that there is another planet that is capable of bearing advanced life. 2. Panspermia carries with it the idea that our genetic code and intracellular makeup came from outside our solar system. This of course requires somewhere out in the universe there was a prebiotic soup, DNA/RNA self-organization and all the other low probability events that I already spoke of. My summary: all panspermia does is take the same EXTREMELY unlikely events and push them out somewhere in the universe.
Remember all advanced life in the universe requires information content and only carbon can hold information. Silicon can only be minimally linked and the other possible choice, boron, is exceedingly rare. And carbon-based life requires a rocky planet with all the probabilities on p. 151.
i completely disagree with this. we're here, and there's life all over the planet, but no, it couldn't happen anywhere else in the enormous universe...right. :-/
You can never say couldn't. I'm just saying that imo the probability is so low that you cannot build a theory about the universe/life around it.
Hoyle was a genius, but keep in mind that the design parameters on p. 151 were only beginning to be uncovered when he wrote about panspermia. I'm sure he knew of some of them and could "feel" others, but he was probably largely unaware that a life-bearing planet is such a low probability event.
Bad Design in the Panda's Thumb? A new study analyzed the giant panda's thumb using computed tomography, magnetic resonance imaging (MRI) and related techniques. Contrary to what evolutionists have previously expressed about the "bad design," the current study shows that the radial sesamoid bone (its "thumb") is "one of the most extraordinary manipulation systems" among mammals.2 The radial sesamoid bone functions as an active manipulator, enabling the Panda to grasp bamboo stems between the bone and the opposing palm. Contrary to previously published studies, a computerized analysis of the three-dimensional images indicate that the radial sesamoid bone does not move independently of its articulated bones, but acts as part of a functional unit of manipulation. The radial sesamoid bone and the accessory carpal bone form a double pincer-like apparatus enabling the panda to manipulate objects with great dexterity. The metacarpals, radial sesamoid and radial carpal bones function as a unit to grasp objects. The accessory carpal acts as an additional "finger" when the hand grasps food. The abductor pollicis brevis, opponens pollicis, and abductor digiti quinti muscles further serve in grasping when contracted during grasping. Evolutionists say that the design of the Panda's thumb is bad compared to that of the primate opposable thumb. However, the opposable thumb is not designed for continuous grasping. Such kind of usage can result in carpal tunnel syndrome (just ask any laboratory technician who has been pipetting for many years). Being a herbivore, the Giant Panda spends nearly all of its waking hours eating. It collects bamboo leaves by grasping and stripping leaves from the stalks. Contrary to what the evolutionists say, the opposable thumb would be a bad design for the Panda, since it could not function under the stress of continuous use. The Panda's hand, with its "thumb" bound to the metacarpals, is a much stronger design able to withstand continuous use. The authors concluded their study with the following statement: "We have shown that the hand of the giant panda has a much more refined grasping mechanism than has been suggested in previous morphological models." 2.

Another example of jumping to conclusions without considering intelligence and design.
Hereâs some examples from where those numbers come from: 1. Sagan himself came up with one of them. He and another scientist observed that stars must be of a specific mass density. If the mass density is too small, then the planet must be significantly closer to the star. And tidal interactions go up exponentially with the distance closer to the star. The rotational period in this case quickly goes from days to months! (Both Mercury and Venus experience this.) A larger mass density leads to even greater problems: the star burns too quickly and erratically for advanced life. Sagan himself noted that only 1/1000 stars would have a reasonable mass density. 2. An advanced-life planet must be orbiting one and only one star. Of course, a planet ripped away from a start will be too cold and a planet orbiting a binary system will have too unstable of an orbit and will frequently pull the planet into deadly temperature zones.. Only about ¼ stars are bachelor stars. 3. Most galaxies have stellar densities that are far too high to support advanced life. If stars are too close, then their gravitational interactions would disrupt planetary orbits. And of course if the stellar density is too low, then heavy elements will be thinly distributed to produce a proper rocky planet for advanced life. 4. Most people do not realize only 5% of all galaxies are the âniceâ spiral galaxies like the Milky Way. The other 95% are elliptical or irregular. In elliptical galaxies, star formation ceases before sufficient rocky planet material can generally form. With irregular galaxies, you have two problems: 1) they have active nuclei, so any life would be bombarded with the nastiest of radiation and 2) they also do not sufficient heavy element concentration to form the kind of rocky planets necessary for advanced life. When you put these together, you get the list on p. 151.
