Finally! Some much needed rain and cooler temps…..and those damn squirrels are eating up my satsuma crop…….
The weekend and I would like to talk about space, a subject that I frequently post……..
Soon we will be going to the stars….not in my life time but soon…..but how will we fuel the ship that takes us to the next world we will screw up?
Will we use some sort of FTL (Faster Than Light) propulsion? Or maybe solar winds? How about a nuke powered space craft? Then there is the old reliable the “wrap drive”……
First will FTL mean time travel as well?
Time-traveling through space might still sound like a common plot in sci-fi movies today but now some scientists actually believe that the theory is very possible in real life.
According to a report, a wormhole could make space traveling to very distant regions of the universe happen in an instant. This theory discussing how the anomalies of physics could make time traveling real was recently discussed in a scientific paper authored by physicists from Princeton University.
The study titled “Traversable wormholes in four dimensions,” discussed how physicists Juan Maldacena, Alexey Milekhin and Fedor Popov have “constructed a traversable wormhole solution in four dimensions.”
How close are we to FTL?
New Scientist is reporting that NASA engineer David Burns is making some bold claims about a conceptual new spaceship thruster he calls the “helical engine” — a concept the magazine admits “may violate the laws of physics.”
“The engine itself would be able to get to 99 per cent the speed of light if you had enough time and power,” Burns told New Scientist.
A page out of a Star Trek script…..wrap drive……
It’s hard living in a relativistic Universe, where even the nearest stars are so far away and the speed of light is absolute. It is little wonder then why science fiction franchises routinely employ FTL (Faster-than-Light) as a plot device.
Push a button, press a petal, and that fancy drive system – whose workings no one can explain – will send us to another location in space-time.
However, in recent years, the scientific community has become understandably excited and skeptical about claims that a particular concept – the Alcubierre Warp Drive – might actually be feasible.
This was the subject of a presentation made at this year’s American Institute of Aeronautics and Astronautics Propulsion and Energy Forum, which took place from August 19th to 22nd in Indianapolis.
How about those solar winds we hear about…..if it can power a satellite then why not a space craft?
LightSail 2, The Planetary Society’s solar sailing spacecraft, has spent more than two months in orbit.
During that time, the bread-box-sized spacecraft deployed a set of silver Mylar sails and began to climb, proving that the small satellite can raise its orbit without a drop of conventional fuel. Propelled solely by the power of the sun, the spacecraft has shown that solar sailing may be a viable means of propulsion.
With LightSail 2’s primary mission complete, the rest of the spacecraft’s time in orbit — about a year, all told — provides a great chance for folks around the world to glimpse the spacecraft for themselves. According to Bill Nye “The Science Guy” and his team at The Planetary Society, skywatchers around the world can spot the spacecraft as it glides above Earth — if the conditions are just right.
That leaves the possibility of using a nuke to power a space craft……
The War Zone has been reporting on a set of bizarre patents assigned to the U.S. Navy that describe radical new technologies that could absolutely revolutionize the aerospace field, and frankly, the very way we live our lives. These include high-energy electromagnetic fields used to create force fields and outlandish new methods of aerospace propulsion and vehicle design that basically read as UFO-like technology. You can learn all about these patents, their viability, and the issues surrounding them in these exclusive features of ours. Now, the same mysterious Naval Air Warfare Center Aircraft Division engineer behind those patents has produced another patent—one for a compact fusion reactor that could pump out absolutely incredible amounts of power in a small space—maybe even in a craft.
How will we get from Earth to some a waiting craft?
How about an elevator?
A growing number of scientists and space-technology enthusiasts are looking into ways to construct a huge elevator, either on Earth or the moon, that could transport cargo to and from space.
In a study published in September, which has not been peer-reviewed, two graduate students proposed a version of a space elevator that would stretch from the moon to Earth’s satellite-level orbit. They said the structure could be built with current technology.
We left out “worm holes” and “Ion Drives”……
But now you have an idea/s of how this will work……
