Thinking normally is sometimes the enemy of good science.
Normal scientific evidence would indicate that a wave cannot travel without propagating through a medium:
- Sound waves don’t travel in thin air.
- Ocean waves don’t propagate without water.
So light waves must propagate through some tangible medium, scientists thought in the late 19th century. Thus they postulated ether. It took a very clever experiment by Michelson and Morley in 1887 with advanced instruments to show that light does not propagate through luminescent ether.
Normal scientific evidence indicates that space and time provide an absolute frame of reference.
- When you and I both click precision stopwatches at the same moment, then let them run for the exact same interval, they stop simultaneously.
- Newtonian mechanics predict the planetary orbits with extreme precision. And they work the same way no matter where in the solar system you are observing.
This is our normal experience. Yet we now understand, as a result of Einstein’s theories and innovative experiments, that space is curved, there is no such thing as an absolute frame of reference, and time runs at different speeds depending on the velocity of the object which is measuring time.
Likewise, our normal experience with decay does not prepare us for what can happen with unusual creatures in an unusual state, fossilized in an unusual way.
The unusual creatures are bacteria, and they can exist in an unusual state as endospores. Botulism spores can survive for hours in boiling water, which is why you can get very sick from eating canned vegetables from the wrong garden. Very few organisms can do the same thing; boil one of my cells for 5 minutes, and little if any DNA would remain intact. So we have to think differently about decay when we’re dealing with bacterial spores.
Secondly, the spores were preserved in amber, which provides a protective “cocoon” against the typical forces of decay. For example, a carnivorous fungus of a species which long ago went extinct was remarkably preserved in amber for 100 million years, according to this National Geographic report.
God made a big, big universe, John, and when we use advanced technology like radiometric dating and genomic analysis to examine phenomena that are not part of our daily experience, we are going to be surprised at many turns. So I want to encourage you to read this article about reviving 25-40 million year old bacteria spores; let yourself be surprised. Enjoy the feeling of wonder!
P.S. The links to the articles about 250 million year old spores no longer worked, so I dug up the account of ~32 million year old bacteria spores instead.
