Time Machine

A time machine would violate the first law of thermodynamics would it not?(Oh, and I agree, Eta)

Without a doubt standard thermodynamics would not apply. The symmetry of time translation is lost (out goes the 1st Law) and the arrow of time is kaput hence the 2nd law bites the dust.And impossible not to agree about Yaro being hot.Game set and match for hotness.

Pfff.Such machine will be useless. With the luck we have it will just be for one person. No camera, nothing to digg or bring back some samples.
Won't work because of this.Denesha

yes its does but then again they say black holes do

The is no such 'thing' as time, it is merely the fourth measure of motion.You cannot travel back in something that does not exist.Time is our own construct.There never can and never will be 'time travel'.We do not even travel forward in time, time is entirely extent.There are no theories in Science that can give structure to time.[This message has been edited by V-Bird, 03-22-2004]

Time link Thought this was in keeping with the subject. Other opinions on the matter of time.

Faulted to say the least.

"There never can and never will be time travel"
Do you have evidence to support this statement?
I for one have been jet lagged on more than one occasion.
I am not saying you are incorrect I am simply curious about how you are so confident in your statement. Please enlighten me.

When Einstein proved the Theory of Relativity, he also proved the connection between space and time. For example, an atomic clock travelling at high speed in a jet ticks slightly more slowly than its counterpart on the ground. The difference is extremely small when we're dealing with jets and cars and such, but at velocities approaching the speed of light, the effect is enormous. So in fact, we use time machines everyday. At least to move forward in time.I don't know too much about how it works, but I have been explained that if we ever will be able to use wormwholes (also proved by Einsteins theory of relativity), we would also be able to travel back in time Read more about it here: Illinois Institute of Technology: 404 Resource Not Found

Phi, simply that time does not exist.Everything that is around you is simply energy, not just the cables that lead to your computer but you and the table your computer sits upon is energy, the 'difference' that you perceive between that stuff in the cable and the other 'harder' stuff that makes you and the table is that one is unbound by other energies, everything that exists is held in sway by these great forces, these forces act upon energy to produce the very fabric of all you perceive.Time has no energy component, it therefore does not physically exist, it is a 'construct' an 'abstract' we use to determine and and relate things.While we are at it, we may as well nail the other great 'stupidity' of modern times...Space does not exist.This at first seems hard to believe, but think for a moment, I am not saying that there is not 'distance' between things in the Universe as there patently is.But space again as an entity does not physically exist, it is nothingness thru which bound energy [matter] and unbound energy [light] can travel.So now we can nail the last dumb phrase that I wish were consigned to the History.Spacetime... as both parts do not exist, it does not exist.We are bound by our Physicality, we move thru Physical things, we can't move thru the non-physical, because that only exists in our imagination, the same half-ahsed place god [s] came from.[This message has been edited by V-Bird, 03-22-2004]

That is the worst corruption, to your own end, of Relativity I have read for a while.

OK, I admit my English is not as good as it should be (and that my knowledge of Einsteins theories lacks a little, I must admit), so my last reply may have come out wrong.But apart from that, it has been proved that time moves slower on moving objects (this has been done scientificly by placing an atomic clock on a Boeing 747, while another was placed on the ground). By comparing the two clocks after the flight, it showed that time had moved slower on the plane.The theory of going back in time, goes something like this (once again, excuse my poor english):
If you could open up a wormehole, and place one end on Earth and the other at a spaceship going close to the speed of light, you could go through the wormhole from Earth to the spaceship, a place that was back in time compared to time on Earth. Don't hold me to this, but I'm sure that is how it was explained. You could of cours not go further back than the existens of the wormhole.Anyway, timetraveling is mathematicly pheseable, but will remain a theory until proven wrong.Hope that came out right

We can't bend space and travel through foreshortened worm holes there is no space to bend. That means it can't be foreshortened.We can't jump to other dimensional planes for time travel, space is nothingness, therefore it has none of the attributes of dimensionality.Put 2 objects on the table in front of you, take out a tape measure and record the distance between them, have you actually measured 'space' or the relationship of one to the other.Are you getting the picture?

Your english is fine, it is your train of thought that is muddled.Let me put it simply...If we could travel as a quantum of energy [the speed of light]... where is time?The simple answer... it's not there.It's not there because it's not an attribute of energy.Because it's not an attribute of energy, it can have no physical properties to manipulate.This means that time can't fundementally effect energy and energy can't fundementally effect time.

Time travel cannot be mathematically feasible because we have no mathematics for time!
