On December 17, 1903, at Kitty Hawk, North Carolina, the 1903 Wright Flyer became the first powered, heavier-than-air machine to achieve controlled, sustained flight with a pilot aboard.
On this date in 1969, Neil Armstrong, aboard the Apollo 11 Lunar Lander, along with Buzz Aldrin, touched down on the surface of the moon. Michael Collins waited aboard the Command Module, orbiting the moon.
You run and you run to catch up with the sun but it's sinking
Racing around to come up behind you again.
The sun is the same in a relative way but you're older,
Shorter of breath and one day closer to death.
"Time" by Mason, Waters, Wright, Gilmour
Through the insights of the brightest minds, we begin to see evidence of Tachyons, particles that travel backwards in time, and through experimentation with the LHC, we begin to see elementary particles.
Mind you, the theory was a proper theory in the sense that it was mathematically consistent, and also because it predicted certain observable consequences-namely, that if tachyons existed they would emit a certain type of radiation (Cerenkov radiation) in a vacuum. This radiation was searched for, and none was found. So, after a flurry of excitement, physicists lost interest in tachyons and went on to more massive hypotheses, such as black holes. As far as physicists are concerned, tachyons do not exist. (Committee for Skeptical Inquiry)
There is a Canadian company called D-Wave which has the first commercially available quantum computer, and is set to release a 512 qbit version by the end of this year. Add Artifical Intelligence to this computing capability, and the possibilities are mind-boggling.
Traditional computer process information as bits that can be a 0 or a 1. Quantum computers utilize the potential of quantum mechanics by making its bits a 0, a 1, or a 0 and a 1 simultaneously. This “superposition” lets it do many calculations at once, where a traditional computer can only perform one.
It would appear the only restrictions on this technology are the limitations imposed by the speed of light, but future experiments may produce instantaneous transfers.
The experiment was carried out by scientists at Hefei National Laboratory for Physical Sciences in Anhui, China. During its course, the scientists took two quantum entangled particles. One was sent to a distant quantum memory node while the other was present at the lab. The scientists then altered the state of the photon in the lab and it directly affected the state of the distant photon. This is a very exciting development for the world of quantum computing as well as those researching on faster modes of communication transmission. If indeed this progress can be translated into greater, more sophisticated system, it would mean that we can create the fastest data-transmission machines in the near future.
Will it be possible in the future to be placed inside one of these machines, have your whole body mapped into digital form, and transmitted by Quantum Tunneling to another location in space and time?
An MRI system can create axial images as well as sagitall (slicing the bread side-to-side lengthwise) and coronal (think of the layers in a layer cake) images, or any degree in between, without the patient ever moving.
While it is true that a Tachyon is a putative particle, at one point in time the Higgs Boson was also just theoretical particle, until recent discovery by the LHC at Cern. The detection of a Tachyon would by it's very nature be very difficult to prove, a particle that resides just above the speed of light.
Absolute, true and mathematical time, of itself, and from its own nature, flows equably without relation to anything external, and by another name is called duration: relative, apparent and common time, is some sensible and external (whether accurate of unequable) measure of duration by the means of motion, which is commonly used instead of true time; such as an hour, a day, a month, a year. (Isaac Newton, cited in Philosophy of Physics: Space and Time by Tim Maudlin, pg 13.)
Space and time are the framework within which the mind is constrained to construct its experience of reality. (Immanuel Kant)
he seems to be describing a "Star Trek" transporter, not a time machine
However, no such radiation was discovered by any test, so the uniform conclusion of physicists is that tachyons do not exist
we have invented measurement of space in order to be able to quantify distances, we have invented measurement of time in order to be able to quantify durations. By this perspective, time is not really anything -- it is merely the intellectual imposition of order.
This theory has a wide range of consequences which have been experimentally verified, including counter-intuitive ones such as length contraction, time dilation and relativity of simultaneity.
1. Once transmitted digitally, how is the body re-assembled into it's original biological form?
2. How does the body return, if the transmitting unit is at the origin point?
In truth, a teleporter, which I'm sure my opponent has no problem with, would still transmit across time, but in such in a tighter field, and only moments into the future.
To measure a particle traveling faster than the speed of light requires equipment that hasn't been devised yet.
So then perhaps Einstein was wrong with Special Relativity, and if time is a mere sequential measurement, then odd effects such as time dilation cannot exist.
'First round both debaters opened very strongly, both using very good scientific logic and the steady progess of mankind as strong bases for an opener, while both maintaining a somewhat tongue-in-cheek approach to Hollywood’s portrayal of time travel and how easy it seems. For the first round, due to a better explanation of the cons of the realities of time travel, the round goes to Adjensen.
Second round, Druid42 attempted to explain how we as humans could go about achieving the possibility of time travel, but as it would seem didn’t have the room to extrapolate the theory properly, instead delivering a more ‘teleportation’ based theory than one of time travel. Adjensen however in the second round recovered somewhat strongly, expanding on his previous post regarding the impossibilities of time manipulation and dimension given any forms of technology. Even though the information in the second round was only marginally more than in the first, the second round goes to Adjensen for a once again more concise reply.
Last round Druid42 began to address the issues his opponent had raised, and gave some very strong retorts to Adjensen’s ideas in the second round. He recovered strongly by bringing the facts to the table and opening the possibility of how time travel could actually work.
However, Adjensen had one last card to play, and this statement;
The inevitable plot hole of any time travel story is that with such a device, anything in any time can be done. Screwed something up? No worries, just go back five minutes earlier and inform yourself of the error. That didn't work, either? Go back five minutes before that. Repeat until you get it right, because you always have five more minutes.
Is very convincing to the con stance of time travel.
A very difficult debate to judge given the complex nature of the topic, but adjensen is the winner on this one.'
Although both contestants brought up valid points, I feel that Druid42 has prevailed. While Druid42 has shown that the future is full of possibilities and such a machine/concept is a future possibility, adjensen maintained a present sense of technology not looking toward the future of possibilities. Their arguments are based on what it is we know and understand today without giving leeway to what we may understand tomorrow.
As we do not understand how such a machine would impact our past/future we can only argue against by the standards we now have the ability to grasp and I don't feel that they made a good enough argument to nullify the possibility as a future occurrence.
wont profess to understand exactly what these two great debaters were talking about, but overall the case adjensen built seemed to be more coherent. I actually also learned something about the possibilities of time travel from adjensen who was debating against time travel. This part especially sold me to adjensens side:
"Why is the timeframe of the receipt of a time machine of no relevance? Because once it exists, ever and anywhere, it exists always and everywhere. It doesn't matter if such a device isn't invented for a million billion years, because it takes away any limitations on where and when it can be".
He did well in showing the logical inconsistences inherent in Druids side.
What I liked best about Druids debate is the idea of first proving that instant movement of matter through space looks to become a possibility in the future and then extrapolating from that the idea of movement through time. He buffered this point with "Rose's Law", showing the exponential progress of mankind. This was a brilliant move that swayed me to his side of the debate for a short while.
I would prefer Druids side to be true (wouldn't we all?) but at the end of the Debate I feel that adjensen made the slightly stronger case.
