I just posted the first few chapters of a super heroine series. If there is enough interest, it may become a graphic novel.

This is a great graphic showing the relative power needed to get to any of the major bodies in our solar system.

NASA’s Warp Drive Project: “Speeds” That Could Take a Spacecraft to Alpha Centauri in Two Weeks Even Though the System is 4.3 Light-Years Away, Video

A  few months ago, physicist Harold White stunned the aeronautics world when he announced that he and his team at NASA had begun work on the development of a faster-than-light warp drive.

His proposed design, an ingenious re-imagining of an Alcubierre Drive, may eventually result in an engine that can transport a spacecraft to the nearest star in a matter of weeks — and all without violating 
 The idea came to White while he was considering a rather remarkable equation formulated by physicist Miguel Alcubierre. In his 1994 paper titled, “The Warp Drive: Hyper-Fast Travel Within General Relativity,”
Alcubierre suggested a mechanism by which space-time could be “warped” both in front of and behind a spacecraft.
Michio Kaku dubbed Alcubierre’s notion a “passport to the universe.” It takes advantage of a quirk in the cosmological code that allows for the expansion and contraction of space-time, and could allow for hyper-fast travel between interstellar destinations.

Essentially, the empty space behind a starship would be made to expand rapidly, pushing the craft in a forward direction — passengers would perceive it as movement despite the complete lack of acceleration.
White speculates that such a drive could result in “speeds” that could take a spacecraft to Alpha Centauri in a mere two weeks — even though the system is 4.3 light-years away.
In terms of the engine’s mechanics, a spheroid object would be placed between two regions of space-time (one expanding and one contracting).
A “warp bubble” would then be generated that moves space-time around the object, effectively repositioning it — the end result being faster-than-light travel without the spheroid (or spacecraft) having to move with respect to its local frame of reference.
“Remember, nothing locally exceeds the speed of light, but space can expand and contract at any speed,

Well said!
If someone says that you have to respect their opinion, their faith, their ideology, or any other idea, it's usually because they have no genuine logic or reason to back it up and are instead trying to fool you into thinking it's wrong to criticize. It's not. In fact, it's essential to healthy thinking. Don't fall for the compulsory respect of ideas!

I'd love to see this up close, some day.
What is 'Alcantara' ? Or Al-Kantara-as-Saif ?
Okay. I went to the  Spanish town of Alcantara today to get something from the pharmacy, and of course I had to cross that damn bridge over  the Tejo... the bridge is almost 2000 years old and proves the jest that all bridges in Spain were built by either the Romans or the EU ;)

So, the Romans built this bridge - the Goths later took over the Roman province, only to be  conquered by those Evil Arab Moors - who named the place 'The Sword Bridge'... there's a legend that a golden sword is hidden within the building. The Christian took it in the 13th century and massacred most of the Moors - 'Matamoros' is a Spanish family names as 'Alcantara' or 'de Alcantara' might be. Btw there are quite a few other places in Spain with the name 'Alcantara', usually near rivers.
It hurts to see trucks and other traffic go over this bridge - but then, the Romans built for eternity... the brutes hadn't yet mastered the finer points of built-in decay we 'modern'  know-it-all cats practice so very well !

The plaques set into the bridge say, "Dedicated to the Emperor Nerva Traianus, Caesar Augustus, Germanicus, Dacicus... to the curiosity of voyagers who like to learn new things, and maybe ask themselves who built this and for what reason - this bridge, destined to last forever through the centuries of the world, was built by Caius Iulius Lacer, famous for his divine art." And so it remains.  It's almost 200 meters across, 71 meters high, and solid as a rock.

As the family name of the guy was Iulius, the architect was a remote relative of that other Caius Iulius, who gave the 'Caesars" their name.

Here is an interesting project. Not sure how it will pan out with the establishment that makes money from keeping things too complicated for mere mortals.
