Comment Re:Can we even detect ourselves from beyond LEO? (Score 1) 534

Exactly what I was thinking, especially since a story about Cassini is on the front page as well. Could Cassini ascertain that life exists on Earth from its orbit around Saturn? I would think the answer is surely no.

Using the lower bar set by the parent post, I did find a experiment was run by Galileo during its Earth flyby:

The cosmologist Carl Sagan, pondering the question of whether life on Earth could be easily detected from space, devised a set of experiments in the late 1980s using Galileo' s remote sensing instruments during the mission's first Earth flyby in December 1990. After data acquisition and processing, Sagan et al. published a paper in Nature in 1993 detailing the results of the experiment. Galileo had indeed found what are now referred to as the "Sagan criteria for life". These included strong absorption of light at the red end of the visible spectrum (especially over continents) which was caused by absorption by chlorophyll in photosynthesizing plants, absorption bands of molecular oxygen which is also a result of plant activity, infrared absorption bands caused by the ~1 micromole per mole (mol/mol) of methane in Earth's atmosphere (a gas which must be replenished by either volcanic or biological activity), and modulated narrowband radio wave transmissions uncharacteristic of any known natural source. Galileo' s experiments were thus the first ever controls in the newborn science of astrobiological remote sensing.

People who believe that the speed of light must have drastically changed over the course of several thousand years are capable of pretty much any type of cognitive dissonance.

Interesting example. A variable speed of light is one answer to the horizon problem, and that is postulating very large changes in the speed of light over a time scale of a tiny fraction of a second just after the Big Bang.

When I recently did a Mint XFCE install, I was actually surprised by how much the current look mirrors KDE. It is less resource intensive, but not by much... perhaps 20% less RAM usage.

LXDE is the clear go-to for minimal requirements, too bad Mint doesn't have an offering with it as the default.

And yes, they also have a Paypal type service, but it would have to clear a large number of hurdles to become trusted in the US.

Lack of trust certainly hasn't kept Paypal from being popular.

Just read the countless stories... they can do pracatically anything they want with the money in "your" PP account.
