When a big old star runs out of fuel, it collapses of its own weight. That's what appears to be happening to Christianity, at least in the advanced countries where it once dominated.
Sometimes you have to change course to get on course. And the first small step in doing so may be to realize you didn't really know where you were going in the first place - and why.
We don't know the answer to that. But every crew that resides on the International Space Station provides us information that we use to adjust our protocols and that extends that period of time.
If you are at all interested in astronomy, chances are you've already heard that the Hubble Space Telescope is celebrating its 25th anniversary this week. What some people may not know is that Hubble is one of four siblings, so to speak.
Let's ignore the technologies that might be impossible (e.g. warp drive, dilithium crystals, and transporters). Let's ignore the technologies that we have no idea how to reproduce in a similar way (artificial gravity). Let's just focus on trying to build a space-worthy scale replica of the USS Enterprise that uses existing structural and propulsion capabilities.
Many years ago, when I was helping to staff the Department of Defense with senior political appointees, I was present when Bolden turned down a senior position in the administration. During the early days of the Obama Administration, this was just not done.
If Rihanna does in fact feel the growing changes in the US, we must ask ourselves a greater question: if a celebrity--a citizen that is very removed from the face of danger or misdeed--is feeling distraught over America's current state, what does that mean for our country?
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.
