Social media is turning us into thoughtless political extremists
Your Facebook feed is a virtual echo chamber. It serves the same purpose as Fox News or MSNBC.
Big Think Managing Editor Jason Gots recently penned a keen piece on political radicals on Facebook that got me thinking about the ways social media has altered our political rhetoric. At the risk of sounding too much like I'm sucking up to the boss, much of Jason's piece articulated the exact trepidations I feel about my own social media pals:
"There's this disconnect between your Facebook voice (always out for blood) and your in-person voice on those rare occasions when we meet (warm, funny, kind). I'm not saying this is a good thing — the not-talking-explicitly. I just don't like ugly arguments and ad hominem attacks, which I fear (with good reason) is what would happen if I responded to your Facebook posts, which, honestly, have gotten on my nerves to the point where I've hidden them from my News Feed."
Fulfilling the title of his blog — "Overthinking Everything" — Jason delves deeply into the topic. He rallies against the frustrating elements of extremism while questioning how the Facebook radicals of the world would behave should they ever achieve the power they seek. It's an interesting take that's really worth a read. What's that? There's something brown on my nose? I don't know what you're talking about.
The following isn't so much a response to Jason's piece as it is a minor digression or corollary. It began, fittingly, as a Facebook comment in which I attempted to explain why social media (like almost all contemporary media) is bad for political conversation. I should note that I feel the same about irritating conservatives on social media as I do about irritating liberals, though with the caveat that on most issues I lean toward the latter.
Two reasons why social media is bad for us, politically:
1. The echo chamber: I think a huge part of why we've become so divided as a society stems from the binaries mentioned in Jason's piece. Just as conservatives reinforce their anti-liberal sentiments by watching Fox News (and vice-versa with liberals and MSNBC), folks on Facebook curate their audience to form an echo chamber. It's basically self-structured propaganda, which is inherently anti-liberal by the classical definition. Flashier, more inflammatory ideas rise to the top of the conversation thus fueling the sorts of radical biases and heuristics that subconsciously radicalize people. The middle ground shrinks as rhetorical forces seek to push people farther left or farther right. I don't think that's healthy for a society, especially when radicalization comes attached to a sense of mean-spiritedness against the other side.

2. Tactics and tone: The whole public-shaming culture bugs me because it portrays conflicting opinions as, at best, the stupid ramblings of uninformed idiots; at worst, straight-up evil. People act differently online than they do in person, often for the worse, because we see other people online as characters in a larger digital drama rather than real human beings. It engenders a sense of enmity against our peers that ought not have any place in a respectful and democratic society. It also kills me to see people shun, demean, or shame the ignorant, because ignorance is not always the result of volition. Demonization is lazy. It alienates people who might otherwise have come around to your beliefs had they not been made to feel bad. Social media and the SJW mindset (as much as I hate that term) both promote a shouting-down of the opposition rather than a thoughtful attempt to sway opinion. It, by design, divides rather than unites.
3. Memes are the lowest form of political discourse: I mean seriously, come on...
How are we supposed to have deep political discussions when so much of our rhetoric is splashing around in the kiddie pool? This is probably our current era's most chronic ill. Our collective attention spans are so short that most of us only crave shareable, single-serving doses that reflect our own worldview rather than pursue a thorough understanding of how the political world works. And those in the traditional media (who are ostensibly responsible for keeping the public informed) feed those cravings all the way to the bank. Social media isn't necessarily responsible for this (we are), but it's sure not helping things.
A Mercury-bound spacecraft's noisy flyby of our home planet.
- There is no sound in space, but if there was, this is what it might sound like passing by Earth.
- A spacecraft bound for Mercury recorded data while swinging around our planet, and that data was converted into sound.
- Yes, in space no one can hear you scream, but this is still some chill stuff.
First off, let's be clear what we mean by "hear" here. (Here, here!)
Sound, as we know it, requires air. What our ears capture is actually oscillating waves of fluctuating air pressure. Cilia, fibers in our ears, respond to these fluctuations by firing off corresponding clusters of tones at different pitches to our brains. This is what we perceive as sound.
All of which is to say, sound requires air, and space is notoriously void of that. So, in terms of human-perceivable sound, it's silent out there. Nonetheless, there can be cyclical events in space — such as oscillating values in streams of captured data — that can be mapped to pitches, and thus made audible.

The European Space Agency's BepiColombo spacecraft took off from Kourou, French Guyana on October 20, 2019, on its way to Mercury. To reduce its speed for the proper trajectory to Mercury, BepiColombo executed a "gravity-assist flyby," slinging itself around the Earth before leaving home. Over the course of its 34-minute flyby, its two data recorders captured five data sets that Italy's National Institute for Astrophysics (INAF) enhanced and converted into sound waves.
Into and out of Earth's shadow
In April, BepiColombo began its closest approach to Earth, ranging from 256,393 kilometers (159,315 miles) to 129,488 kilometers (80,460 miles) away. The audio above starts as BepiColombo begins to sneak into the Earth's shadow facing away from the sun.
The data was captured by BepiColombo's Italian Spring Accelerometer (ISA) instrument. Says Carmelo Magnafico of the ISA team, "When the spacecraft enters the shadow and the force of the Sun disappears, we can hear a slight vibration. The solar panels, previously flexed by the Sun, then find a new balance. Upon exiting the shadow, we can hear the effect again."
In addition to making for some cool sounds, the phenomenon allowed the ISA team to confirm just how sensitive their instrument is. "This is an extraordinary situation," says Carmelo. "Since we started the cruise, we have only been in direct sunshine, so we did not have the possibility to check effectively whether our instrument is measuring the variations of the force of the sunlight."
When the craft arrives at Mercury, the ISA will be tasked with studying the planets gravity.
The second clip is derived from data captured by BepiColombo's MPO-MAG magnetometer, AKA MERMAG, as the craft traveled through Earth's magnetosphere, the area surrounding the planet that's determined by the its magnetic field.
BepiColombo eventually entered the hellish mangentosheath, the region battered by cosmic plasma from the sun before the craft passed into the relatively peaceful magentopause that marks the transition between the magnetosphere and Earth's own magnetic field.
MERMAG will map Mercury's magnetosphere, as well as the magnetic state of the planet's interior. As a secondary objective, it will assess the interaction of the solar wind, Mercury's magnetic field, and the planet, analyzing the dynamics of the magnetosphere and its interaction with Mercury.
Recording session over, BepiColombo is now slipping through space silently with its arrival at Mercury planned for 2025.
Water may be far more abundant on the lunar surface than previously thought.
- Scientists have long thought that water exists on the lunar surface, but it wasn't until 2018 that ice was first discovered on the moon.
- A study published Monday used NASA's Stratospheric Observatory for Infrared Astronomy to confirm the presence of molecular water..
- A second study suggests that shadowy regions on the lunar surface may also contain more ice than previously thought.

The observations suggest that a cubic meter of the lunar surface (in the Clavius crater site, at least) contains water in concentrations of 100 to 412 parts per million. That's roughly equivalent to a 12-ounce bottle of water. In comparison, the same plot of land in the Sahara desert contains about 100 times more water.</p><p>But a second study suggests other parts of the lunar surface also contain water — and potentially lots of it. Also publishing their findings in <a href="https://www.nature.com/articles/s41550-020-1198-9#_blank" target="_blank">Nature Astronomy</a> on Monday, the researchers used the Lunar Reconnaissance Orbiter to study "cold traps" near the moon's polar regions. These areas of the lunar surface are permanently covered in shadows. In fact, about 0.15 percent of the lunar surface is permanently shadowed, and it's here that water could remain frozen for millions of years.</p><p>Some of these permanently shadowed regions are huge, extending more than a kilometer wide. But others span just 1 cm. These smaller "micro cold traps" are much more abundant than previously thought, and they're spread out across more regions of the lunar surface, according to the new research.</p>

But if there is, it would mean that water would be much more accessible to astronauts, considering they wouldn't have to travel into deep, shadowy craters to extract water.</p><p>Greater accessibility to water would not only make it easier for astronauts to get drinking water, but could also enable them to generate rocket fuel and power.</p><p style="margin-left: 20px;">"Water is a valuable resource, for both scientific purposes and for use by our explorers," said Jacob Bleacher, chief exploration scientist in the advanced exploration systems division for NASA's Human Exploration and Operations Mission Directorate, in a statement. "If we can use the resources at the Moon, then we can carry less water and more equipment to help enable new scientific discoveries."</p>
