Could Fossils of Ancient Life From Earth Reside On the Moon?
MarkWhittington writes Does the moon contain fossils of billions of years old organisms from Earth? That theory has been laid out in recent research at the Imperial College of London, reported in a story in Air and Space Magazine by Dr. Paul Spudis, a lunar and planetary geologist. The implications for science and future lunar exploration are profound. Scientists have known for decades that planets and moons in the Solar System exchange material due to impacts. A large meteor smashes into a planet, Mars for example, and blasts material into space. That material eventually finds itself landing on another planet, Earth in this case. Mars rocks have been discovered on Earth since the 1980s. Other rocks from the moon and, it is surmised, Mercury have also been found, blasted into space billions of years ago to eventually find themselves on Earth.
The issue is we'd likely need to be digging for decades to find something that might have something, if it hasn't been broken down so much from high radiation in solar storms.
It would be a very long search for that needle.
Even on Earth as we find fossils, these are just fossils that are LUCKY enough to have survived all that time. The majority of skeletons aren't lucky and degrade.
There are very likely large numbers of life we will never* know about that filled various niches, was the in-betweens of one lifeform and another as it evolved over millions of years.
We have also just barely scratched the surface. The deeper we go, the older we are finding. (especially in the cold pole regions)
Just recently we found that cave with stupidly old stuff in it, several billion years old if I remember.
There are likely millions of little caves like this scattered all over the planet where life has been hidden away and protected .
Also aliens. And pyramids.
*unless we make time machines.
Because *YOU* and *I* aren't even paying enough taxes for the government to pay its bills for the stuff it's already doing right now
We don't have a tax problem, but an appropriations problem. We collected over 3 trillion in taxes last year and only 1% went to science and technology. That's abysmal, but reflects our overall stance to disregard facts and science (selective ignorance), and indulge our gross sense of self entitlement.
Economically speaking, there are only two areas of government spending that have a positive ROI, research and development (10:1), and infrastructure (3:1). If you are concerned for future generation, the last thing you want to cut are these two areas of spending. If you really want to fix the problem, cut medicare, medicaid, welfare, social security and military spending.
Brilliance without wisdom, power without conscience. Ours is a world of nuclear giants and ethical infants.
This reminds me of a time that I showed picture of the LHC to a few (ahem Republican) colleagues and lamented that we stopped work on the SSC. That started a debate and they started lecturing me that the SSC was a frivolous waste of tax payer money. This was back in the bowels of the Iraq war and I reminded them that the entire SSC project would have cost less than two months of the war in Iraq.
It was one of those rare moments where you could see a light turn on. They realized it wasn’t a matter of whether the war was necessary and justified or ill-conceived and evil. They realized the raw trade off humanity makes for whatever reason. They considered the fantastic scale and complexity of the LHC and how it embodied a small facet of humanity’s capacity to achieve and progress and weighed it against a blip in one campaign of misery and devastation.
BTW, I’m neither a hawk nor a dove. Humanity is too often brutal, and I have always had a certain respect for and fascination with the spirit and technology of the military in the face of that brutality. Humanity is a long way from peace on Earth. That doesn’t mean I don’t grasp the almost incomprehensible loss of prosperity and potential humanity accepts to maintain and flex the machines of war (many of which are economic) and the conflicts that allow those machines to flourish.
