Trappist-1 System – NASA
By now, everyone’s heard the news – there’s seven new planets to consider in the universe. We’ve all read the headlines. Seven lovely orbs holding potential for life, only a mere 40 light years away! Why, that’s practically next door! And some of them hold the potential for life? Incredible.
While it’s nice to consider that we have an escape plan to another world, it’s kind of unreasonable to expect to get to any one of these places anytime soon. Sure, we’re all expecting to hop on a space ship in the next couple of dozen years and arrive at planet du jour within a Einstein’s calculated period. And Lord knows that the folks behind Prometheus practically guarantee travel to new Edens (although not without some pesky grey, hissing creatures with a penchant for sucking people’s innards and faces).
Are there wormholes to get us to these places quicker? Could be. Interstellar makes an excellent argument for that. If those wormholes do exist, the common folk won’t hear about them, at least not yet. Existing in theory and written about aplenty, I’ve no doubt these gateways to universal superhighways are around somewhere.
How then, is it possible to construct a vehicle to travel within the confines of a wormhole? Sure, we can throw a ship together – that’s the easy part. I’m wondering how a ship might be able to withstand whatever that wormhole throws at it – pressure gradients, temperature, forces binding the wormhole together. Or suppose the wormhole is a perpetual vortex that leads to nothingness? Once trapped inside, the travelers can’t break free and are subjected to extremes not even imagined?
Could there be different categories of wormholes? There must be. Just as there’s different types of highways, roads and streets, wormholes have characteristics. Some may be dead ends, short jaunts or long, winding roads. There could be ones that have celestial potholes, breaks, connect at junctions or turn back on themselves.
Suppose we do discover a wormhole in the neighborhood of Jupiter, as mentioned in Interstellar. Do we send our best and brightest through it just to see what happens? Do we travel to the unknown hoping to reap the benefits of what other places and methods of navigation can teach us? How do we steer our crafts, once caught in a wormhole if we don’t fully understand what they are in the first place? What is speculation and reality? Or will time trick us to believe there is a light at the end of the wormhole, only to find out we’re no longer able to function because of the forces of the universe bearing down on us? If we’re not able to return to Earth, what good is the journey to begin with?
Eventually, some intrepid group of astronauts will go forth to see what’s out there. We may never hear from them again. But they might find another system such as Trappist-1, and create a world that no citizen of Earth may ever be so fortunate to imagine.

Yes, I’ll admit I’m a geek. I married one, too. So of course we felt it necessary to see “Interstellar.” We read up on it, exchanged speculations on the theories behind it, compared different viewpoints, opinions, reviews, all of that. After all of this effort, a sensible decision was cast to go and see it, already.
So last night, after first ducking into Target to purchase some chocolates to stick into our pockets so we wouldn’t have to pay the ridiculous price of $4.oo for a $1.oo candy bar, we went. It was great to go into a theatre filled with our kinds of people, equally geeky and completely silent during the showing, with only the rare murmur of approval over a spectacular scene.
Naturally, we weren’t disappointed. Both of us loved it and spent the ride home discussing it. And I could go on about this, that or the other thing regarding the vagaries of space-time travel and the physics behind it.
Why would I? You know all that anyway.
What got me were the small touches, the little hints of things to come and viewpoints either behind the characters or the writers who invented them. First on my list were the books on the shelves in Murph’s bedroom. How many of you took a good look at them? Here’s two that caught my immediate attention: “The Stand” and “Outlander.”
“Outlander” caught my eye because Diana Gabaldon wrote this book regarding a portal that transports a woman through time, and Stephen King’s “The Stand” because the human race is nearly killed off in that one. Both of those elements were the story in “Interstellar.”
Actually, books do figure prominently in the movie. Take, for example, the school district’s reliance on “corrected versions” of history. The moonwalk was all propaganda to economically bankrupt the Soviet Union. After all, the Soviets never made it to the moon, so that propaganda campaign must have worked. Yet Murph refuses to believe it all and listens to her father, who reinforces the truth.
All that talk about chemical compositions and how it affects environments and circumstances also gave me the goosies. The way how too much nitrogen in an atmosphere isn’t ideal or any atmosphere’s makeup is so sensitive to various forms of life made me smile.
But really, when you get right down to it, the use of time as a resource and element defined the film. Everything from the father Cooper as a younger man visiting his daughter Cooper as she lay dying, much older than he (all right, how many of you also knew that was Ellen Burstyn?), to the astronaut left behind for 23 years when Brand and Cooper seemed to be gone only minutes? Or the gradual shift of Earth from viable to slowly dying, which seemed to take both an interminable and finite amount of time?
I could go on about many, many more things about why we enjoyed “Interstellar” so much, but that would take time, so if you haven’t seen it, take the time and go!

What’s your preferred method of space travel? Is it this?
Or this?
I know, I know. Pretty hard to decide which one to choose.
Allow me to provide you with a clearer example. This is a depiction of the first equation:

Give up? Here’s a clue: There’s a connection between this:
…and the space it occupies.
And the answer is…WORMHOLES!
Okay, okay, maybe I’ve gotten a bit esoteric for you. I’ll get simple.
The first mathematical equation is otherwise known as traversable wormhole, or one that allows you to move from one end of the universe to the other. The second one represents a Schwartschild wormhole that, for the most part, is a black hole that allows travel usually in one direction, but also connects one universe to the other.
The definition of a wormhole is a method within the theory of relatively of moving from one point in space to another without crossing the space in between. To properly explain a wormhole properly means one has to drag out the big guns (i.e. Einstein) and spew forth a lot of verbiage that’s guaranteed to gloss over the heartiest of eyeballs. A short history of the term is this: Albert Einstein and his colleague Nathan Rosen came up with the basic principles of wormholes and their relation to time and space in the 1935 and called their concept the “Einstein-Rosen” bridge. John A. Wheeler, an American theoretical physicist coined the term wormhole in 1957.
Science fiction writers have jumped on the concept ever since. Carl Sagan, Arthur C. Clarke, Iain M. Banks, John G. Cramer, Stephen Baxter and many, many others have all used wormhole technology to develop their plots, as well as popular shows as the Stargate franchise.
With wormholes, one easily solves the problem of traveling great distances in short times, as long as you don’t exceed the speed of light (a wormhole no-no). Just about anything can travel through them as well. The mightiest of space vehicles right down to tiny gnats can zoom through distant reaches to discover, conquer or just make new friends. It’s a simple device that captures everyone’s imagination because it’s so freeing and limitless. Need to get someplace? Hook up to a wormhole, and in seconds, you’re there.
In Stargate SG-1, the cast would travel so quickly through these things that bullets came flying right out of the gate, thanks to the wormhole. Conversely, robotic probes made their way out into the new planet, seeking information regarding conditions. True, a proper stargate was needed to connect two points together. It wasn’t without its risks, either. Wormholes invite all sorts of malfeasance, if one isn’t careful. Evil characters often took advantage of this plot device and wreaked havoc, threatening Earth and its inhabitants over and over again.
Next time you look up at the sky and gaze at the stars, think about this: somewhere out there lurks a bridge to another time. One day, maybe soon, some thing might be transversing it to visit.
