Information Is Beautiful has an interactive data visualization to help you decide if we're alone in the universe.
As usual, for them, it is well done, fun, and informative.
For the slightly geeky amongst us, the model lets you adjust the estimate by playing with two equations: the Drake equation and the Seager equation.
The Drake equation estimates how many detectable extraterrestrial civilizations exist in our galaxy and then in the Universe based on factors like habitable planets, change of life, and then intelligent life, and then the amount of time a civilization sends signals into space.
The Seager equation is a modern take on the equation focusing on bio-signatures of life that we can currently detect - for example, the number of observable stars/planets, what % have life, and then % chance of detectable bio-signature gas.
For both equations, Information Is Beautiful lets you look at various default options but also playing with your own numbers to do the math.
For example, the skeptic default answer for Drake's equation shows 0.0000062 communicating civilizations in our galaxy and which is still 924,000 in the universe. The equivalent for Seager's equation shows 0.0009000 planets with detectable life in our "galactic neighborhood" and 135,000,000 planets in our universe.
Even with the "lowest possible" selection chosen, Drake's equation still shows 42 communicating civilizations (Douglas Adams, anyone?) in the universe.
One of the most interesting numbers (and potentially influential numbers for me) is the length of time a civilization sends signals into space. Conservative numbers are 420 years, but optimistic numbers are 10,000+.
If any aliens are reading this ... don't worry, I won't tell. But, we will find out if you voted in the last election.
Do Candles Smell Worse?
Covid-19 rates are still rising in many places, and there's an unexpected consequence ...
Candle companies are getting much more negative reviews. Angry people everywhere seem to be reporting that the candles have no smell! With Covid, perhaps they need to check if they've lost their sense of smell or taste (and whether they have a mild fever).
Katie Petrova, on Twitter, did some research to check if there was really a correlation.
And the results were as expected. In 2020, consumer ratings for scented candles declined much more than unscented candles, and there are spikes in reviews mentioning lack of scent during months with increased cases.
That being said, unscented candle reviews are lowering too ... which makes you think about the confounding variables. Are sales simply increasing to the point where reviews (and thus negative reviews) are increasing? Is it a result of people being bored/frustrated at home?
I'd be curious to see how much candle (or other home scent improving products) purchases increased during 2020.
