Neil deGrasse Tyson Says This Is His Most Important Message Ever
Astrophysicist Neil deGrasse Tyson releases an emotional video on the state of science in America.
Famed astrophysicist Neil deGrasse Tyson released an emotional new video in which he passionately implores Americans to reconsider how they are increasingly relating to science.
In the post accompanying the video on his Facebook Page, Tyson wrote that this video contains “what may be the most important words I have ever spoken".
He explains that innovation through science is how America, a “backwoods country," became “one the greatest nations the world has ever known".
“Science is the fundamental part of the country that we are," says Tyson [0:35]
But something has been changing in the way some Americans view science and it's greatly worrisome to Tyson. When it comes to making decisions about scientific topics, he sees that “people have lost the ability to judge what is true and what is not."
Case in point - American politicians.
“When you have people who don't know much about science, standing in denial of it and rising to power, that is a recipe for the complete dismantling of our informed democracy," warns Tyson. [1:00]
This stark statement is followed by an archival clip of then-congressman Mike Pence saying that evolution should be taught as a theory not fact.
The video, directed by Sarah Klein and Tom Mason, proceeds to show news clips of science under attack, with people questioning vaccines, GMOs and climate change.
Today's America is “not the country I remember growing up in," laments Tyson.
He brings up the 60s, the 70s, and the civil rights movement to point out that he doesn't remember any time in recent American history when people were denying what science was, implying that this is what's happening today.
Tyson defends science as an “exercise in finding what is true". The scientific method involves testing hypotheses and peer review. Out of such a process rises what he calls “emergent truth" which is “better than anything else we have ever come up with as human beings".
Science is “not something to toy with," according to Tyson. You can't choose to believe an equation like E=mc^2. Of course, he may be overstating there. You could very well propose an alternate equation as such is the way of science.
He forcefully says that the “emergent truths" arrived at through science are “true whether or not you believe in it". And what is important is for people to understand that and move on to political conversations on how to solve our real problems.
Tyson focuses on climate change as an issue that is demanding our agreement - people need to get on the same page that this is a serious problem and work to solve it. He alludes to “carbon credits" or tariffs as possible topics for a political conversation that should have been had years ago, but keeps getting delayed because too many are in “denial".
He calls upon Americans as voters and citizens to become scientifically literate to be able to make intelligent decisions about the issues.

Physicist Frank Wilczek proposes new methods of searching for extraterrestrial life.
- Nobel Prize-winning physicist Frank Wilczek thinks we are not searching for aliens correctly.
- Instead of sending out and listening for signals, he proposes two new methods of looking for extraterrestrials.
- Spotting anomalies in planet temperature and atmosphere could yield clues of alien life, says the physicist.
1. Atmosphere chemistry<p>Like we found out with our own effect on the Earth's atmosphere, making a <a href="https://ozonewatch.gsfc.nasa.gov/facts/hole_SH.html" target="_blank">hole in the ozone layer</a>, the gases around a planet can be impacted by its inhabitants. "Atmospheres are especially significant in the search for alien life," <a href="https://www.wsj.com/articles/looking-for-signs-of-alien-technology-11581605907" target="_blank">writes Wilczek</a> "because they might be affected by biological processes, the way that photosynthesis on Earth produces nearly all of our planet's atmospheric oxygen."</p><p>But while astrobiology can provide invaluable clues, so can looking for the signs of alien technology, which can also be manifested in the atmosphere. An advanced alien civilization might be colonizing other planets, turning their atmospheres to resemble the home planets. This makes sense considering our own plans to terraform other planets like Mars to allow us to breathe there. Elon Musk even <a href="https://www.space.com/elon-musk-serious-nuke-mars-terraforming.html" target="_blank">wants to nuke the red planet.</a></p>

2. Planet temperatures<p>Wilczek also floats another idea - what if an alien civilization created a greenhouse effect to raise the temperature of a planet? For example, if extraterrestrials were currently researching Earth, they would likely notice the increased levels of carbon dioxide that are <a href="https://www.epa.gov/ghgemissions/overview-greenhouse-gases" target="_blank">heating up</a> our atmosphere. Similarly, we can looks for such signs around the exoplanets.</p><p>An advanced civilization might also be heating up planets to raise their temperatures to uncover resources and make them more habitable. Unfreezing water might be one great reason to turn up the thermostat. </p><p>Unusually high temperatures can also be caused by alien manufacturing and the use of artificial energy sources like nuclear fission or fusion, suggests the scientist. Structures like the hypothetical <a href="https://bigthink.com/paul-ratner/this-mind-bending-scale-predicts-the-power-of-advanced-civilizations" target="_self">Dyson spheres</a>, which could be used to harvest energy from stars, can be particularly noticeable. </p>

As patients approached death, many had dreams and visions of deceased loved ones.
One of the most devastating elements of the coronavirus pandemic has been the inability to personally care for loved ones who have fallen ill.
Research reveals a new evolutionary feature that separates humans from other primates.

- Humans have evolved to use less water per day than other primates.
- The nose is one of the factors that allows humans to be water efficient.

Being skeptical isn't just about being contrarian. It's about asking the right questions of ourselves and others to gain understanding.
