Man and nature

I’m a firm believer that it isn’t going to be aliens who stomp humanity. It’s going to be something we created.

Because when Skynet becomes self aware or when we get sucked into the Matrix,  someone’s going to ask the computers how do we fix the planet? The answer’s going to be, “Get rid of the humans.”

And when it comes to protecting the planet, humans keep showing they have the morality of Peter Lorre’s character in “M”.

Riding light and sending sounds in space

The speed of light is 186,000 miles per second. That’s per second, not per hour. If you travel at the speed of light for an hour, you cover 671 million miles.

That’s fast, right?

Well maybe on Earth it is, but the universe is a big place. It took about five hours for the signal from the New Horizons probe to travel from Pluto to Earth. And that’s traveling at the speed of light.

To put it in perspective, take a look at this if you’ve got 45 minutes to spare:

That’s how long it would take to get from the Sun to Jupiter: 45 minutes.

Forty-five minutes of nothing but emptiness with a few big space rocks called planets, moons and asteroids showing up every few minutes to break up the monotony. I bore easily, so if it took this long to get to Jupiter, imagine how many “Are we there yet”s I’m going to ask on a trip to Pluto.

If we’re ever going to get to other parts of the galaxy, we’re going to have to break the light barrier. Which means we’re probably not going anywhere. Maybe a billion years from now, our robot satellites in space like Pioneer, Voyager and New Horizons will be picked up by some alien civilization, which will ask: What the hell is this?

This is the Golden Record we sent on Voyager back in 1977: a collection of greetings in different languages, sounds of life and selections of music, plus a roadmap to where we are. Voyager has left the solar system and is now in interstellar space.

So let’s say Voyager does end up on a planet in another part of the galaxy where there’s intelligent life. What do you think the aliens would say? Maybe this?

The ‘Galaxy Quest’ rap

Galaxy Quest,” the Star Trek parody from 1999, is one of my favorite science fiction movies. Actors in a long ago cancelled television SF show called “Galaxy Quest,” are transported to a spaceship by aliens who have based their entire culture on the “historical documents” that we know as reruns. And the aliens need the actors, who they believe are really the characters in the historical documents  to combat an evil genocidal reptilian foe.

But 16 years after the movie came out, I just came across this “Galaxy Quest” rap by Sigourney Weaver, Sam Rockwell and other members of the cast:

Sigourney Weaver is pretty hot as a blonde. If you’ve never seen the movie, check it out. It’s very well done.

Here’s are some scenes that didn’t make it into the final product:

Never give up! Never surrender.
