 We Have the Power to Accelerate Things to Near the Speed ...

Six years ago, in the distant Trisolaran stellar system, Trisolaris accelerated two hydrogen nuclei to near the speed of light and shot them toward the solar system. These two hydrogen nuclei, or protons, arrived at the solar system two years ago, then reached the Earth.

 Directionality in Zero-G

Phrases like “things are looking up” and “look at the upside” once meant something like “consider the good in the situation,” but they went through an ironic shift in the solar system’s early spacecolonial culture, mutating in the microgravity of early tin-can stations to mean a variety of practically sarcastic sentiments, typically something like “be careful” or “let’s be realistic.” The joke (that is, that there is no “upside”) wore off in a hurry, but use it wit...

Many of the phrases we use on Earth make no sense in space.

 O'Neill Cylinders

The O’Neill cylinder is named after an American physicist and space scientist who sought to engage his students by getting them to think about big problems—space settlement, in particular. He also led symposiums where the concepts behind large, permanent space habitats—including the cylinder that bears his name—were hashed out. The basic principle is fairly simple. Construct a cylinder at least half a kilometer in diameter so that it can be rotated at low speed and provide 1 g of art...

 What are Dilithium Crystals

Finally, the Star Trek writers added one more crucial component to the matter-antimatter drive. I refer to the famous dilithium crystals (coincidentally invented by the Star Trek writers long before the Fer-milab engineers decided upon a lithium target in their Antiproton Source). ...What do these remarkable figments of the Star Trek writers' imaginations do? These crystals (known also by their longer formula 26 dilithium 21 diallosilicate 1:9:1 heptoferranide) can regulate the matter-antima...

 The Enterprise's Impulse Drive

Moving back to the sub-light-speed world: We are not through with Einstein yet. His famous relation between mass and energy, E=mc 2 , which is a consequence of special relativity, presents a further challenge to space travel at impulse speeds. As I have described it in chapter 1, a rocket is a device that propels material backward in order to move forward. As you might imagine, the faster the material is propelled backward, the larger will be the forward impulse the rocket will receive. Mater...

The ship uses hydrogen fusion to propel helium atoms at near the speed of light, but this hypothetical form of propulsion would require incredible amounts of hydrogen to work.

 The Picard Maneuver

Speaking of time, I think it is time to introduce the Picard Maneuver. Jean-Luc became famous for introducing this tactic while stationed aboard the Stargazer. Even though it involves warp travel, or super light speed, which I have argued is impossible in the context of special relativity alone, it does so for just an instant and it fits in nicely with the discussions here. In the Picard Maneuver, in order to confuse an attacking enemy vessel, one's own ship is accelerated to warp speed for a...

The captain of the Enterprise has the ship travel faster than light, leaving an image of itself traveling at the speed of light from its previous location; meaning Star Trek's universe would be filled with such apparitions.

 The Thrill of Landing on a New Planet

To ANYONE who has been in space and experienced its changelessness, the real excitement of space flight comes when it is time to land on a new planet. The ground speeds backward under you as you catch glimpses of land and water, of geometrical areas and lines that might represent fields and roads. You become aware of the green of growing things, the gray of concrete, the brown of bare ground, the white of snow. Most of all, there is the excitement of populated conglomerates; cities which, on ...
