How Does Film ACTUALLY Work? (It's MAGIC)
For most people, film is obsolete. I remember having a camera as a kid and there was something magical about cameras before technology came along.
As best as I can recall, I didn't really bother with cameras from my college days onward. It wasn't till sometime in my early 40's I got the most primitive digital camera possible, that only took 640x480 pictures, which matched some early computer monitor resolutions. I actually had fun with this camera despite the pretty low quality. Eventually, mobile phones could take pictures even before smartphones.
In 2008, I got an iPhone 3G which had a 2 megapixel camera.
In 2010, I got an iPhone 4 which had a 5-megapixel camera.
In 2012, I got an iPhone 5, which had an 8-megapixel camera. I still own this phone. The metal bands around the edge of this phone made it pretty tough, which allowed it to survive a pretty big accidental drop onto the pavement. This will be relevant below...
In 2014, I got an iPhone 6+ which also has an 8-megapixel camera. When I tried to participate in an Apple battery replacement program, something went wrong with the phone, so they gave me a free replacement which I still have.
Years later I got an iPhone 6S+ on a Black Friday sale. It has a 12-megapixel camera. Because the wi-fi died on in, I bought another one of these on another Black Friday to replace it, which is still my primary phone.
Today I dropped my iPhone 6s+ and the screen cracked, but I managed to get it repaired the same day for $89.

How To Terraform Venus (Quickly)
https://www.youtube.com/watch?v=G-WO-z-QuWI
This seems unrealistic to me.
To terraform Venus, we should engineer a photosynthetic bacterium that can live in the upper atmosphere and consume CO2. Not sure that is possible.

The early Earth was hell with an atmosphere of 42% CO2 and enough pressure to crush a man flat. Photosynthetic bacteria changed the atmosphere.

What If Earth got Kicked Out of the Solar System? Rogue Earth
The most likely nightmare scenario is millions of years distant. The worst-case scenario might be billions of years distant.
