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 to play with your own choices to adjust the outcomes.
For example, the skeptical default answer for Drake's equation shows 0.0000062 communicating civilizations in our galaxy (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 significant 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.
Billion ... With A B
Humans are notoriously bad at large numbers. It's hard to wrap our minds around something of that scale. We're wired to think locally and linearly, not exponentially (it's one of the reasons I love AI so much).
Here are a couple of ways to help you understand a billion dollars.

Next, let's look at spending over time. If you were to spend a dollar every second for an entire day, you would spend $86,400 per day. You can do that for approximately twelve days if you have a million dollars. With a billion dollars, you can do that for over 31 years. Ignoring the difference between net worth and cash, Jeff Bezos could spend $9M per day for over 31 years.
If you make $100K a year, you can earn $1 million in 10 years. At the same rate, it would take you 10,000 years to make $1 billion.
Here is an example framed around spending money. Imagine that someone making $50K a year decides to buy a laptop, a car, and a house. Now we're going to make a relative comparison of the cost of those items for people making a lot more than $50K per year. To do this, we'll shrink the cost of the price of those items (to see the relative cost-to-income ratio). For a millionaire, a laptop might cost the equivalent of $100 dollars, a Porsche would cost $3,000 dollars, and a house would cost $25,000. Now, let's say you're Mike Bloomberg, and you're worth $60B. A laptop's relative cost would be pennies, a Porsche's relative cost would be less than 60 cents, and a mansion's relative cost would be around $500 dollars. You could have everything you ever wanted for a minute fraction of your wealth.
For a different perspective, here's an interesting visualization from informationisbeautiful. It shows various examples of things worth billions of dollars – including the personal wealth of several billionaires.

Okay, last one before I show a video ...
Let's try explaining the concept of a Billion through time. Fifty thousand seconds is just under 14 hours. A million seconds was 11 days ago. A billion seconds ago from today? 1990. Pretty crazy.
Here's a video from the 1970s that helps you understand scale through the power of tens – and an exploration of our universe.
Hope you enjoyed this. Let me know what you think.
