In the first article in this series, I discussed the Drake Equation and its suggestion that intelligent life could exist elsewhere the Milky Way galaxy. In the second article, I examined the Fermi Paradox, which implies that the lack of extraterrestrial contact at this point in the galaxy’s evolution cannot be reconciled with what we should expect to see according to Drake.
In an effort to reconcile the claims of Fermi, Drake, and a host of other astronomical theorists throughout human history, mankind has made some of its first planned and scientifically sound efforts at rooting out whether intelligent life does, in fact, exist elsewhere in the Milky Way galaxy.
In the first part of this article series, I discussed the Drake Equation and its suggestion that the galaxy might be teeming with intelligent life. However, a major contradiction to the fundamental implications of the Drake Equation comes in the form of the Fermi Paradox, a logical quandary first observed by physicist Enrico Fermi in the early twentieth century.
Assuming an asteroid is on an imminent collision course with Earth, there are a number of ways we might prevent it. The asteroid could be slowed down, sped up, or by slightly changing its trajectory just enough so that it does not intersect with Earth’s orbit when and where Earth happens to be.
The phenomenon – first theorized by Albert Einstein – affects the rate at which time passes for objects moving at different speeds. What does this have to do with GPS? The answer relates to how orbits work.
The modern global position system (GPS) has revolutionized the way we locate and navigate everything from the family SUV to the jumbo jets crisscrossing the international airways. As such, we often take this invaluable tool for granted – that is, until we know how it works.
