In our Part I article, we mentioned how numerous scientists over the past 65 years, since Fermi first raised the question "Where is everybody?", have examined Fermi's paradox and have proposed solutions. There is still no easy answer.
Last week I received an invitation from an associate at Marriott's headquarters to the 25th Anniversary of the Hubble Telescope. I was really interested in this. His wife works for NASA and when he did some digging, he found many references to Marriott and NASA.
Yes, I know the current push by our Federal Space Agency on social media is #JourneytoMars, but are we ready? Really ready? Nope, I don't think we're even close.
Just as a hurricane drives rain, wind, and floods, the space weather arising from a solar eruption can come in different forms. First comes the light from a solar flare, disrupting high-frequency radio communications more or less immediately.
Much of the opposition to Mars exploration is based on disinformation and distraction tactics that imply or even claim outright that Mars would bust the budget or endanger Social Security, which, given actual budgetary facts and context, is preposterous.
Cosmologists propose that the universe was until recently a lifeless collection of particles. But they have ignored a critical component of the cosmos because they don't know what to do with it. This component, consciousness, is an utter mystery. How did inert, random bits of matter ever morph into Obama or Lady Gaga?
Unless you call yourself a rocket scientist, you probably don't think your daily routine has much in common with flight software engineering. But you would be wrong. If you skip the bits about the flying, disregard the software and pay no attention to the engineering, then what you're left with is some amazingly useful life lessons.
Their research, a hydroponic plant growth system that relies on centripetal force to work in microgravity, almost ended there, until they met someone with industry experience and an alternative way to raise capital.
Becoming an astronaut is easily the dream of many but sometimes that's all it ever is -- a dream. For Leland, who happens to be the 13th African American astronaut, that all became a reality through patience, hard work, and a knack for problem solving.
There are no passengers on Spaceship Earth, only crewmates, and we all have a responsibility to mind the ship and take care of our crew-mates. In fact, when we pull back temporally and look at long-term effects, it becomes apparent that we must collaborate, for the survival of life on Earth.
We are living in an interdependent world. The major challenges that face humanity are global in nature. We need to develop more interdependent thinking in order to deal with them.
Some lessons can be taught by wise people, and others have to be learned from making mistakes. Learning to appreciate the things that can easily become expected, is the latter.
Navigation requires a reference frame. We need reference frames to tell us where we are with respect to other objects and we need reference frames to tell us how we are oriented with respect to other objects. There is no single universal frame that is used for all operations.
Imagine looking up and seeing a ring of little pearls in the sky that are human habitats, or knowing there are trees growing on the Moon and the first human babies are being born on Mars who will call it their Home.
New data from the Planck satellite indicates that the cosmic microwave background pattern once thought to be from gravitational waves is an artifact of galactic dust.
If we adopt the same collaborative mind-set and practices that got us to the moon and back, and that built the International Space Station, we can alleviate poverty -- and do much more.
