Gliese 581: Extrasolar Planet Might Indeed Be Habitable:
http://www.sciencedaily.com/releases/2007/12/071213101403.htm
Citat: "...
Last but not least, the possible habitability of one of these planets is
particularly interesting because of the central star, which is a red
dwarf, M-type star. About 75% of all stars in this Galaxy are M stars.
They are long-lived (potentially tens of billion years), stable, and
burn hydrogen.
....
Both studies definitely confirm that Gliese 581c and Gliese 581d will be
prime targets for the future ESA/NASA space mission Darwin/Terrestrial
Planet Finder (TPF), dedicated to the search for life on Earth-like planets.

years away from Earth..."

Nu mangler vi blot et fungerende Alcubierre drive; Warp Drive - lysets
hastighed er jo ikke hurtigt nok...:

http://en.wikipedia.org/wiki/Alcubierre_drive
Citat: "...
Thus, the Alcubierre drive does not contradict the conventional claim
that relativity forbids a slower-than-light object to accelerate to
faster-than-light speeds. However, there are no known methods to create
such a warp bubble in a region that does not already contain one, or to
leave the bubble once inside it, so the Alcubierre drive remains a
theoretical concept at this time.
....
Moreover, Alcubierre has shown that even when the ship is accelerating,
it travels on a free-fall geodesic. In other words, a ship using the
warp to accelerate and decelerate is always in free fall, and the crew
would experience no accelerational g-forces.

Citat: "...It is shown how, within the framework of general relativity
and without the introduction of wormholes, it is possible to modify a
spacetime in a way that allows a spaceship to travel with an arbitrarily
large speed..."

Hvis menneskeheden havde så store mængder anvendelig energi til rådighed
som dine kilder siger er nødvendig for at bøje rummet og forkorte
interstellare afstande, hvad behøvede vi så at rejse til fjerne stjerner
efter?

Hvis man kan konvertere al solens masse til energi, skulle man tro der
var smartere anvendelsesmuligheder end at lave en warp bobbel om et par
små atomer.

Som f.eks. at konstruere en ekstra planet hvis vi går og mangler en.

Interessant, når universets alder kun er 13,7 mia. år.

Nej. "Tens of billion years" er mindst lig med 20 milliarder år. Så
stjerner kan ikke "potentially" være så gamle i dette univers.

Long-lived referer vist til deres forventede levetid - ikke til deres
alder på nuværende tidspunkt, så der er intet modsætningsforhold...

Måske har Burkhard Heim ret.

Hej Vidal

Citat fra link: "...
Sandia runs an X-ray generator known as the Z machine which "could
probably generate the necessary field intensities and gradients".
...."

Lidt om Z machine - med billed:
http://en.wikipedia.org/wiki/Z_machine
Citat: "...
When the Z machine fires, the energy from a 20-million-ampere electrical
discharge vaporizes an array of thin, parallel tungsten wires, creating
plasma. Simultaneously, the electrical current creates a powerful
magnetic field that compresses and implodes the plasma by means of a
z-pinch process.
....
Z releases 80 times the world's electrical power output for a few
billionths of a second.
....
A $60 million refurbishment program was announced in 2004 that will
raise the power output to 350 terawatts. The refurbishment, which
started in July of 2006, includes the installation of newly designed
hardware and components and more powerful Marx generators.
....
The Z machine is now able to propel small plates at 34 kilometers a
second, faster than the 30 kilometers per second that Earth travels in
its orbit around the Sun, and three times Earth's escape velocity.
...."

Lidt om:
http://en.wikipedia.org/wiki/Marx_generator
Citat: "...A bank of 36 Marx generators is used by Sandia National
Laboratories to generate X-rays in their Z Machine..."

Nikola Tesla ville sikkert gerne have eksperimenteret med Z machine:

Manden var ikke ligefrem visionsløs: Citat: "...
"As soon as [the Wardenclyffe facility is] completed, it will be
possible for a business man in New York to dictate instructions, and
have them instantly appear in type at his office in London or elsewhere.
He will be able to call up, from his desk, and talk to any telephone
subscriber on the globe, without any change whatever in the existing
equipment. An inexpensive instrument, not bigger than a watch, will
enable its bearer to hear anywhere, on sea or land, music or song, the
speech of a political leader, the address of an eminent man of science,
or the sermon of an eloquent clergyman, delivered in some other place,
however distant. In the same manner any picture, character, drawing, or
print can be transferred from one to another place ..." - Nikola Tesla,
"The Future of the Wireless Art", Wireless Telegraphy and Telephony,
1908, pg. 67-71.
...."

Citat: "...In 1882 Tesla, who had realized that AC held the key to an
efficient power distribution system, successfully designed the needed
motor...Of course Tesla polyphase or three-phase AC power is only one of
the contributions that this little known and seldom recognized inventor
gave to the world..."
