Enjoyed your discussion guys.. OK, here we go.. can we travel faster than light, and can we travel through time? Serious question, serious answers only please.

Oh, and by the way, what relationship are you to Stanley Unwin? (RIP) Deep joy.

Mr P:

Some of us have the right idea already if you bother to read the rest of the posts.

Bally Heck:

Any body above absolute zero radiates heat regardless of its surroundings. It is a dynamic equilibrium, and if its surroundings are at the same temperature, then it will absorb heat at the same rate as it loses it.

I also preferred Tricky's explanation.

I have now donned my cone shaped hat with the D on the front. I am also standing in the corner of the classroom, fully humiliated in front of the other pupils.

Sir tells me that what I should have said was that the amount of heat lost by a body is proportional to the fourth power of the temperature (K) times the area of the body times the Stefan-Boltzman constant.

He also tells me that the temperature of the universe which "What are you on about. As a vacuum cannot contain any heat by defintion,"
is 4 degrees K.

Apparently I can go to my seat soon

Thumbs up

I think I got it now, Noise is what makes things move. Its obvious now, Loud cars go quick, F18 and F111 make lots and lots of noise so they can fly.

A rocket makes even more noise, so it gets into space, here it lets out the sattelite which makes no noise so it stays where it was put. the rocket then turns on the noise generator and heads back to earth. On entering the atmosphere it makes so much noise, that the energy overload causes it to burn up.

So now to the Question , How does the Tardis get around.

Hang on a bit.........if my poor grey matter understands what some of you are saying, then if a rocket DID NOT shut down after attaining escape velocity (and assuming an inexhaustable fuel supply), it would continue to accelerate in this void ultimatley reaching the speed of light?

Nah! there would have to be some friction or something offered at some point by what little is out there and set up "drag" to retard its progress - wouldn't there?.

Toolbox, that is where E=mc2 comes in. And also the rocket will reach a constant velocity when its forward speed is equal to the speed of the gases being emitted from the rocket, as it is newtons reaction (equal and opposite) that makes the rocket accelerate.

Smudger, with reference to the speed of light, scientists have already found particles that travel faster than the speed of light, called quarks, but they only exist for microseconds, but I was theorising that maybe we can only detect them for microseconds because due to traveling faster than the speed of light, they are traveling through time, or maybe they are flicking in and out of sub either, or even existing in more than one place at a time due to traveling in the 4 th dimension....that being time........Just some food for thought

Avtrician,
with reference to the Tardis, there is a beautifully simple answer.

Being a telephone box, the Tardis is effectively a sound device, and as suggested on this forum, the level of sound is really what makes rockets and other things fly. Simple as that.

Newton missed this whole concept because he was looking for something only scientists and nerd schoolboys could understand. Other scientists then built a load of bollocks theory on top to confuse everyone away from the simplicity and the conspiracy has continued.

Yes - the Tardis amplifies and modifies sound in different planes to enable space and time travel along those planes. You have all heard the Tradis sound - there is no other sound like it.

Show me a transporting device that does not involve levels of sound emmission in proportion to it's power! Even in space an idle rocket is just drifting quietly. To alter direction it must cause matter or particles to move or vibrate and this is sound. Who will prove me wrong!

Space vehicles, of course, use gravity (ie planets) to change direction. Gravity does not create noise as it acts simultaneously on all matter and thus cannot create a local compression which then propagates as a sound wave.

So there you have it. Issac was right all along. (Clever bloke - came from near me)

Of course you are right, I forgot about the Whoop Whoop sound of the Tardis on lift off. I am now a totaly happy (if somewhat deranged) person.

Now that I think about it The transporter on The Star Ship Enterprise is sound powered as well.

Now if I could only find out what the meaning of life is.

Hey, keep in mind that the Trekky Transporter doesn't actually give you any speed. You're just there, then you're somewhere else with no real physical movement through space. Time yes, maybe, but not space.

Perhaps it's got something to do with the tone of the sound.

Actually Newton was sorta close but missed an important point.
Gravity only appears to act silently, using your example of space vehicles using it to change direction, a great deal of 'latent' sound is actually produced, the enrgy has to go somewhere, which like latent heat is only released by a change of state.
One needst only observe or hear the latent sound that is explosively released when said space craft or object hits the earth out of control at high speed and changes state.
Latent sound of course, is why we have to plan our descent from altitude carefully in order to allow a managed and careful dissipation of the latent sound built up from our continual fight with gravity enroute.
If we get this and the very final latent noise dissipation stage close to the ground wrong (some call it landing, incorrectly applying the wrong branch of physics), the stupendous release of whats left of the accumulated latent noise can be very embarrasing, indeed fatal in the most extreme cases. We must control this change of state carefully.
One needs only to observe the effects of the release of latent heat in a thunderstorm to have a visual demonstration of the power.
We have seen enough pictures of the effects of the inapproriate release of latent sound to prove this thesis, these unfortunately were not then available to Newton who would have drawn this entirely different conclusion.
The SN (Specific Noise) level of the apple was just not high enough to register above the other ambient parameters.
A simple mistake but understandable in the context of the then technology, given that there were few if any machines capable of generating great volumes of noise.

gaunty, after illuminating our brethren on the science of motion as explained through audio vibration, it may be necessary to begin a thread debunking that electrickery fraud, and explain how smoke generators power our avionics.

I have been trying for years to explain to the Great Unwashed (the masses) that there is no such thing as electricity, and that everything is powered by the instantaneous transmition of smoke via copper (for the most part) lines. no-one will believe me, even though when the TV or Stereo lets the smoke out, that it wont go anymore.

Never mind we that Know the real story will just have to be happy in the Knowledge of the truth,

Halle Lua brother.

Another thread could be called for.

Checkers and Avtrician

So it's safe to "come out" on this subject then.

I have always suspected that this is the actual rather than postulated description of the transmission of electrickery.

Like all physics the simple answer is always the best.

I mean all that smoke generated at the power station has to go some where. Sure in the early days they hadn't got the efficiencies in production sorted so a fair bit of the smoke escaped up the chimney stack whereas with the modern plants they have got it down to almost zero.

But thn I don't have a degree in electrical engineering so what would I know?

I'm with you Avtrician just happy to KNOW.

And when I see the workers milling around the power poles scratching their heads the slow distant smile starts. Smoke is much smarter then they know

Checkboard and Gaunty,
Now you have really let the cat out of the bag!

You can't have smoke without mirrors as any management guru already knows but I suspect they do not have a clear vision of the relationship one to another.

Without mirrors the smoke lacks clear purpose and direction. It is only a mirror that can direct it with the correct lateral and vertical orientation. Being aware that correct verticality is naturally displayed by a mirror some people miss the essential point that lateral rectifiers are required to correct the left/right transposition factor, otherwise the smoke keeps running into itself and goes nowhere. Management types tend to make this error. Pilots, on the other hand, have a thorough understanding of this phenomenon and their smoke always travels smothly along on it's way functioning perfectly.

No doubt this branch of science has been neglected and it is refreshing to see it exposed at last on this forum.

By the way; do you have a Cracked Mirror Drill? A very serious situation can quickly develop if not dealt with promptly with smoke swirling around aimlessly.

Thanks Turbofan, I will, even though others before me have posed the questions and sought the answers in a far more informed and eloquent way than I ever could (I'm just a scarebus driver!). I think a certain Mr Hawking has already led the way but it would be fun to hear people of our ilk discuss the subject.

Cool

My Head is starting to hurt, Im not sure if its because of trying to understand the physics of these great problems that we are trying to solve, or the beer (no cant be the beer).

Smoke , mirrors,???? Yes that combined with sound definitely explains how the Enterprise transporter and the Tardis work, perhaps the black holes work as intergalactic lenses that focus all this energy. Obviously a by product of this is light, which is why we can see to type.

The universe is a wonderful place full of wonderful people ( if they think like us ). I am peace with my self at last. ( However the Kids are on the move and asking for money, so the peace is a little dented at the moment)

Beam me up

pterodactyl and Checkers

I am forever in your debt, as I had not made the connection between pilot mirrors, plural, the management mirror, singular and its interelation with the smooth or chaotic transport of smoke.

I have often worn both hats in my labryinthine career so far and had never made the connection viz the difference.
I now understand why I always had extreme difficulty in reconciling the differences in the imperatives. It was always lateral rectification, or lack of

You are correct this branch of science has been neglected and I feel a new "management theory", "book", "movie" and "lecture circuit fees" coming on.
Perhaps we should collaborate on the book as the psychobabble and management guru market are ever hungry for the "next big thing".
I will call my publisher on Mon with an outline and negotitate an appropriate advance.
So if you could advise your champagne of choice I will order sufficient in to start the juices going eh?

Folks! remember you saw it here first
