It’s amazing how little we know

31 May

The Precambrian or Cryptozoic is the period of the geologic timescale from the formation of Earth (around 4500 million years before the present [BP]) to the evolution of abundant macroscopic hard-shelled fossils, which marked the beginning of the Cambrian, some 542 million years BP. Remarkably little is known about the Precambrian, despite it making up roughly seven-eighths of the earth’s history, and what little is known has largely been discovered in the past four or five decades.

SEVEN EIGHTHS??? Holy crap..87 % of earth’s history is unknown to us? Let’s make this even more amazing..

Humans (Homo Sapiens) are about 250,000 years old or so…of that time..only 6,000 years of our history is known. That leaves over 240,000 of human history completely unknown. It’s amazing how little we know of our past. We have a huge collective amnesia regarding the history of both earth and of ourselves. We are just suddenly one day conscious of self..and learn about functioning in society..but have no clue as to the history of what came before us and where we have been as a species.

Add on top of that that the basic ‘forces’ of nature, the strong nuclear force, the electromagnetic force, the weak nuclear force, and the gravitational force are unknown as to how they work. Sure we can make calculations on their effects and send rockets to the moon using the calculations, but we still don’t really know WHAT the forces are exactly. Theoretical physics attempts to explain them with the holy grail of physics, the grand unified theory. We might be getting closer with Quantum mechanics (i don’t subscribe to super string theory)

Pioneer 10 was launched on March 2, 1972, and until 1997 was sending clear signals to earth of Jupiter. Exciting in ofitself. But there is a problem. (que the “Houston we have a problem” sound bite)

There are unexplained forces tugging at Pioneer and changing it’s course. This basically means everything we thought we knew about gravity is wrong, and we need to go back to the drawing board. This is also Occurring to Pioneer 11.

Which leaves open staggering possibilities that would force wholesale reprinting of all physics books..it could be that:

  • Invisible dark matter is tugging at the probes
  • Other dimensions create small forces we don’t understand
  • -Gravity works differently than we think

This reflects once again the huge difference between science and religion; (other than scientists don’t burn other scientists at the stake who don’t agree with them) Science is always willing to completely change it’s explanation for natural phenomena when faced with new evidence, and willingly admit they were in error. Religion often will cling to their beliefs DESPITE evidence, (for example many fundamentalist Christians believe dinosaurs lived with man and earth is only 6,000 years old and that less than 6,000 years ago the entire earth was covered by water)

Anyway, to add to the list of things scientists cannot yet explain are: How a Venus flytrap closes it’s trap, how a cat purrs, why we get drowsy and need sleep and dream, and more.

Basically, we don’t know shit.

    This is one of the many reasons why I love reading your journal. You always post the most random yet VERY interesting (and thought provoking) information. **ponders**

      and i enjoy yours because you ocassionally post umm..’inspiring’ photos. 😉
      No but besides the beautiful pics of yourself you are a great photographer and seem to write about your problems in a mature way rather than just moaning and whining.
