Meteorites and the true evidence for life…

o-YAMOTO-570

The discovery of tiny carbon-rich balls and tunnels inside a Martian meteorite has once again raised the possibility that the Red Planet was teeming with primitive life millions of years ago.

The meteorite, which fell to Earth during the Stone Age, contains microscopic burrows and spheres that resemble the marks microorganisms leave when they eat through rocks on Earth, scientists report in the journal Astrobiology this month. What’s more, these features seem to have been pressed into the Mars rock before it was hurled off the Red Planet by an impact event, the researchers add. (1)

We are so much unaware of what life actually is, that we are not even close to a consensus on what its results are.

What signs do you look for when searching for life in a meteorites?
What signs do you look for when searching for life in the universe?
What do YOU leave as evidence of your existence?

How is the cosmos different due to the existence of life?

If we are just playing by the rules (a.k.a. “physical laws”) then any “trace” we think we see is just another result of mindless physical processes going on for eternity.

But we know we are more than that.
We know our life leaves traces.

Just not the kind of traces that a SEM microscope could discover…

Viruses as a key to life philosophy…

Viruses are a weird thing. We are afraid of them, but we try to use them as cure for cancer [1]. They seem to challenge the “central dogma” of modern biology, i.e. the movement of information from the DNA to RNA: transfering information from RNA to DNA was found to be routine in retroviruses (such as HIV, which causes AIDS) using the enzyme reverse transcriptase [2]. They seem “bad”, but again who are we to challenge the wisdom of nature which created them?  They challenge everything we know about life and make biologists admit that their definition of what “life” is needs re-tuning, if we are to say that viruses are not living beings [3]. No matter how much modern medicine has evolved, we have not yet come to the position to be able to fight simple viruses – like the flu virus. We are too wise, but yet again too fool to understand those little pieces of gennetic information travelling everywhere around us.

Perhaps understanding viruses passes through understanding the unity of nature as a whole: Everything plays a role in life (even Gollum) and viruses must have a role too vital for so many of them to exist…
