Wormholes

[the bomb]

Answer this. Is it threadjacking if its your own thread.

[Shadowmistress]

......

Fascinating....

[sacajaweeda]

Is it crankyanking if it's your own crank?

[Ripper2860]

thank you for clearing that up Ripper. I don't know where the worm hole goes but now I know what goes in the worm hole.

Just trying to bring a little science into everyday life !!



So -- Taking Einstein's theory of realtivity one step further ...

If you are on a rocket ship approaching the speed of light and are having sex with a 1st cousin -- are they still a relative??

[the bomb]

Yes because thats what crankyanking is.

Yes

[sacajaweeda]

But what's that got to do with rocket ships and shagging your cousin?

[Ripper2860]

Yes because thats what crankyanking is.

A stroll down memory lane ...

Take out the papers and the Trash ...

Yankity-Yank. Yank that Crank !!

[Capmaster]

RIPPER

[the bomb]

I'm so confused.

[BJ_M]

and here i was trying to throw a little learning at you and all i get is crap ...

i'll go back and continue my latex web search now ....

[Shadowmistress]

Let's do the time warp agaaaain.

It's just a step the left.....

[sacajaweeda]

i'll go back and continue my latex web search now ....

Aaah, yes! Useful, practical knowledge.

Keep us all posted on your findings, will ya??!

[Shadowmistress]

Maybe you can apply that scientific mind of yours to find some longer lasting latex for Dolly?

I'm sure he'll make it a sticky

for dollys "owner" - kelvar would not be out of place for dolly's most "used parts" ..

[the bomb]

Did you have to go and tell Cap that?

[Capmaster]

Mmm .....Kevlar

[the bomb]

Will one of the other Mods give BJM a yellow card, look what he did to Capmaster.

[BJ_M]

did he make a little booboo on the couch again ? :P

[vitualis]

i meant to comment that anything approching the speed of light in water (see above) would have the same friction as the light encounters . .. i doubt to much that you could get anything going much faster or even close to -- BUT not to far off using a slingshot effect .. ..

Incorrect.

Firstly, the concept of "friction" is an inappropriate analogy when thinking of different particles going through the medium.

For example, a beta particle (travelling through water) that is ejected from an atomic nucleus from fission will have no difficulty going faster than the speed of light in water (though it won't travel very far). While it is travelling at faster than light (in the water), it will emit Cherenkov radiation.

Let me give you an example/thought experiment.

Say we accelerate a super dense bullet (e.g., an alpha particle) at up to 0.9c (c = speed of light in vacuum). We then have it hit a body of water. The speed of light in water is about 0.75c. Now, the particle will slow down when it hits the water, but it will not slow down instaneously. There will be a short period of time when it's velocity is between 0.75 to 0.9c (i.e., faster than the speed of light in water). During this time, it will emit Cherenkov radiation.

Feynman's positrons might be electrons going backwards in time-

Interesting proposition though one needs to explain why there is the preponderance of matter vs anti-matter. Electrons travelling backwards in time does not explain this. Furthermore, it is difficult to explain entropy as well. That positions are electrons travelling backwards in time is not an accepted hypothesis interesting though it may be.

Antimatter is created by the combination of quantum mechanics and special relativity discovered by Paul Dirac.

Eh?

Paul Dirac's work on a quantum model of atomic theory seemed to predict the existence of a "positive electron". The existence of the positron was confirmed somewhat later making Dirac a hero.

Many of these early theorists, however, hardly had a good understanding of quantum mechanics though (not surprising since they were CREATING the field).

All I know is that we'll truly see how approaching the speed of light truly affects a physical object when man can travel at or faster than such a speed. When man can send a monkey into space at such speeds and sees that his physical nature has been altered by force of speed, then we'll see what new approach we take towards it. until then, an atomic clock is a fallible mechanical device.

[vitualis]

By "we", you only mean "you".

Sorry, but no one is trying to prove to YOU by your standards (sending monkey at relativistic velocities) that time dilation exists. It is a ridiculous antropocentric experiment of no real value.

Time dilation has been shown to exist by numerous experiments some of which I have already explained to you.

The half life of an extremely short lived (i.e., unstable) particle that is the result of high energy collider experiments is not a "mechanical device". The very fact that it "lives longer" the faster we accerate it is pretty much proof for time dilation.

After all, the null hypothesis that time dilation doesn't exist means that we shouldn't be able to detect these particles at all. Fact: we can detect them and their half life is prolonged by increasing their velocity in a particle accelerator.

Again: GPS satellites. We are not talking about just taking an atomic clock up into space and coming back down and saying, "gee whizz, they're different!"

GPS satellites make adjustments to their calculations for the timing of their on board atomic clocks in accordance to the slight amount of time dilation as predicted by general relativity.

If there is no time dilation, then the GPS satellites are progressively making compounding errors in their calculations and GPS would fail to function at all.

If the assumption that time dilation doesn't exist is true, then there must be some sort of unknown physical phenomenon that affects all the atomic clocks on all the GPS satellites in exactly the right way such that it precisely counteracts the incorrect adjustments made.

Sorry, but you just have to accept that time dilation exists and we use its principles in every day technological applications. Your objection is as logical as someone denying that the Earth is round until they can personally take me up in a spaceship and orbit the planet.

Right, this is called a beta+ particle or e+. Also known as a positron.

Are we seaking about kelvar or kevlar here?

That's a rather frightening thought, actually.
Not if you use a file and remove the rough edges first


Cap -- Way to thwart a an blatant "threadjack" attempt by BJ_M !!
The only one who can fully thwart a mod's threadjack is another mod
But BJ_M usually takes 2 or 3 of us

Hey - I can hijack pretty well - does STARWARS mean anything to you???

And to answer the earlier question - NO it isn't threadjacking if you do it in your own thread

[Doramius]

we can detect a hologram, but it's not a physical thing that exists.

[Shadowmistress]

Thank you!!!

[vitualis]

No Doramius.

A hologram is a physical thing and it does exist.

The hologram exists as three dimensional data recorded as interference patterns on a photographic plate -- i.e., it is a physical object. The image is then projected with some form of illumination (i.e., with photons which also exist).

Sure, the actually projected perceived three dimensional object isn't there but that is somewhat irrelevant isn't it?? Just like the "person" in a photo isn't "actually there" or the my reflection in a mirror isn't "actually there" either. These are simply human perceptual irregularities rather than anything else. Our brains interpret visual stimuli in a "contextual" rather than "literal" sort of way which is why we can see a photo as a photo rather than as a simple piece of paper with a complex array of colours.

I see Daoramius hasn't disputed this yet. perhaps he's having trouble identifying his keyboard. maybe it doesn't actually exist.......
