In general, the British heavily relied on American colonial militia units, while the French heavily relied on their First Nation allies. The Iroquois Nation were important allies of the British.
Powell May 10, How would we know? How could we make contact—and should we?
One frequent theme that comes up is the issue of what we would do if we found intelligent life on a planet around another star.
A recent posting in particular caught my eye: And that got me thinking… First, how will we find a truly Earthlike planet?
Despite all the amazing recent discoveries of planets around other stars, astronomers have yet to find a true Earth twin—that is, an Earth-size planet orbiting a sunlike yellow star at an Earthlike distance.
Habitable, maybe; Earthlike, no. The same goes, even more so, for the recently discovered Earth-size planets around the star Trappist These are extremely exciting worlds to study, and it is possible that some of them could support life.
But the Trappist-1 planets orbit a dim red-dwarf star, which means that they are blasted with energetic radiation and are probably tidally locked, with one hemisphere always facing toward the star.
Closer analogs are surely out there, but they are hard to find. But for a planet in a one-year orbit like ours! To confirm that the planet is real—and not, say, a random flickering of the star—you want to observe at least three events.
So you need to watch a lot of stars, and watch them all for several years. Planets in the habitable zones around other stars may not be anything like our own.
Kepler top is a miniature system similar to Trappist Kepler middle is a sunlike star but its key planet is bigger and more massive than Earth. Hurt Second, how would we know if a superficially Earthlike planet is truly habitable?
Another approach is to search directly for other Earths alongside their stars, and then analyze their light. To do that, you need both a very powerful telescope and a highly effective way to block out the glare of the star, since an Earthlike planet would be right alongside it in the sky, but on the order of a billion times fainter!
Astronomers have some clever ideas about how to do that, using either an external light blocker called a starshade flying in front of a space telescope, or an internal device coronagraph built into the telescope itself to create a kind of artificial eclipse.
That will take improved telescopes that are unlikely to be built at least until the s. Proving the presence of any kind of life will be hugely challenging, even after we get past steps one and two above.
For instance, we might detect heavy-metal signatures associated with smelting and other types of simple industry, although that still would not yield unambiguous proof. Some extreme, speculative types of lensing telescopes might be powerful enough to see evidence of cities or geometric clearing of forests; such observations would certainly be a lot more convincing.
Note, by the way, that it would be extremely unlikely to find an alien civilization that is so close to us in technological development, even if intelligent alien life is fairly common.The government encouraged the manufacture and importation of military firearms for the criminals to use. This is intended to foster a feeling of insecurity, which would lead the American people to voluntarily disarm themselves by passing laws against firearms.
