2009, o ano da astronomia

“Isto sou eu na Lua.” Poucas pessoas podem dizer esta frase. Edwin F. "Buzz" Aldrin Jr. é uma dessas pessoas. O astronauta foi o segundo homem a caminhar no satélite natural terrestre, em 21 de Julho de 1969, durante a missão Apolo 11. Armstrong, que estava a tirar a fotografia, ficou reflectido no capacete do companheiro, para sempre.

há beleza na terra, vista de fora

From the Earth to the Moon.
On July 16, 1969, Apollo 11 launched into space carrying astronauts Neil Armstrong, Michael Collins, and Edwin "Buzz" Aldrin, Jr. Four days later, Armstrong and Aldrin landed on the lunar surface, and became the first humans to walk on the moon. Pictured: "Earthrise" over the moon, with the Lunar Excursion Module (LEM) heading to the surface, as seen from Collins' vantage point in the Command Module. Collins, alone in the Command Module, remained in orbit for the two-and-a-half hours that Armstrong and Aldrin were on the surface, rendezvousing with them before the four-day journey home. in LIFE

um planeta a descobrir

Se existirem extra-terrestres que tenham passado pelo nosso canto do Sistema Solar e tenham parado aqui pelo Planeta Terra eles terão visto algo semelhante a esta fotografia. Os discos voadores e charutos andam aí... talvez.

scottie, beam me up

[O Teletransporte. Um conceito tão fascinante quanto complicado de se poder conseguir no futuro. Têm-se feito descobertas, como as notícias que coloco em baixo comprovam, mas mesmo assim ainda parece faltar muito para que seres vivos consigam ser teletransportados. É engraçado pensar nas potencialidades de um possível teletransportador, o imaginário cinematográfico tem permitido ir mais longe e pensar nessas realidades de uma forma entusiasmante, mas também muito preocupante (como é o caso do filme A Mosca) .]

Teleportation: Express Lane Space Travel

Think Star Trek: You are here. You want to go there. It's just a matter of teleportation.
Thanks to lab experiments, there is growth in the number of "beam me up" believers, but there is an equal amount of disbelief, too.
Over the last few years, however, researchers have successfully teleported beams of light across a laboratory bench. Also, the quantum state of a trapped calcium ion to another calcium ion has been teleported in a controlled way.
These and other experiments all make for heady and heavy reading in scientific journals. The reports would have surely found a spot on Einstein's night table. For the most part, it's an exotic amalgam of things like quantum this and quantum that, wave function, qubits and polarization, as well as uncertainty principle, excited states and entanglement.
Seemingly, milking all this highbrow physics to flesh out point-to-point human teleportation is a long, long way off.
Well, maybe...maybe not.

A trillion trillion atoms
In his new book, Teleportation - The Impossible Leap, published by John Wiley & Sons, Inc., writer David Darling contends that ""One way or another, teleportation is going to play a major role in all our futures. It will be a fundamental process at the heart of quantum computers, which will themselves radically change the world."
Darling suggests that some form of classical teleportation and replication for inanimate objects also seems inevitable. But whether humans can make the leap, well, that remains to be seen.
Teleporting a person would require a machine that isolates, appraises, and keeps track of over a trillion trillion atoms that constitute the human body, then sends that data to another locale for reassembly--and hopefully without mussing up your physical and mental makeup.
