Einstein was that meticulous when he derived the Lorentz-FitzGerald Transformations (LFT) from first principles for his Special Theory of Relativity (STR). Therefore, if you think about it, does this mean that momentum is a particle's elementary property that appears to be related to mass?
Americans' Exposure To Heat Extremes Could Rise 6-Fold By 2050 - exposing vastly more Americans to dangerous heat waves due to a combination of rising temperatures and rapid population growth in the South and West, a new study warns.
Today, the Earth got a little hotter and a little more crowded.
Pope Francis's much anticipated encyclical on the environment and address to the UN provides Catholics a rare opportunity to take the lead on presenting the moral argument surrounding climate change.

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.
Last week, the House Science, Space, and Technology Committee, headed by Texas Republican Lamar Smith, approved a bill that would slash at least three hundred million dollars from NASA's earth-science budget, says the New Yorker's Elizabeth Colbert.

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.
There's no way to tell what will unfold when you start to do something, even the smallest thing. Actions grow and expand, sort of like the way our peas started out small, crawled past their trellises and are now getting tangled up into each other.
