Faster than light if i had a big foot

[ErlyRisa]

I may take light 'light years' to reach a destination...but

if i were bigfoot, and was half the size of the universe, then in order for me to see the universe from the other side I would only need to take one step.

yes the postulate is philisophical in nature... which brings me to my piont.

maybe me, being bigfoot, can only occupy the enirety of the universe if I am nothing more than part of the universe as a 'ghost' of information.

--makes me think that god is actually real.

If you were a bigfoot that big you would have to have a very subtle body because your head and your feet wouldn't be causally related...I think this answers your questions.

[ErlyRisa]

but like a game of Chinese Whispers... I can tell my foot to move... faster than what a light beam would take to reach it...

..especially so, if I don't tell it to make a linear step, instead if I cheat and just 'shuffle' around oribitally untill I get to the otherside.

...probably why relativity don't work too well on centripital motion.

[sanctus]

Sorry I don't know the game you refer to so I'm a bit lost.

I read (a long time ago), in a popular Science mag, that information could theoretiaclly travel faster than the bounds that we set upon the universe with spacetime/light.

If this is the case... then if the information was large enough, relative to the universe, than, relativistically speaking, an ant would perceive a flashlight as something the size of the sun, and would have no-hope in ever outrunning it, but I on the other hand, can just place the flashlight on the ground, and make one step (being Big Foot), and in effect out run the speed of light.

--so on a Darwinian, survival of the Human species, stand piont, what do we want to do...become a smaller package so that we can reside in side an atom,,, or go big and ascend to the size of our percieved environment.

We'll be gobsmacked once we know what makes the universe works

The game of Chinese Wispers – also called “telephone” or “rumor” – is simply a demonstration of how information can become distorted in the retelling. One person recites a message to another, who recites it to another, etc., then the last person recites the message to the first, who compares them to see how they changed. Obviously, this means of communication – which is not a bad analogy for how signals travel in a human (or presumably a bigfoot) body – is much, much slower than light.

I believe what ErlyRisa is suggesting is the “long, rigid stick” scenario, which ask, if I push on one end of a long rigid stick, won’t someone on the end immediately feel it, or at least feel it before the light image of me pushing it occurs.

Practically the answer is no. In ordinary materials, the end of a long stick doesn’t experience a push on its opposite end until a “pressure wave” traveling at the speed of sound in that material reaches it. In a material we think of as very rigid, such as steel, the speed of sound is 5000 to 6000 m/s, or about .00002 time the speed of light.

In principle, the stick could be made of some “super material” (such “neutronium” or “quarkium”, degenerate matter equivalent to a giant atomic nucleus or a giant neutron), but even then, it would still be made of fundimantal particles interacting via bosons limited to the speed of light (in this example quarks interacting via gluons), so could only approach, never match or exceed, the speed at which the signal could be sent using light.

actually the principal that I reas in the Mag...went like so.

If we want to communicate with Mars occupants in real time, then we need a medium that is faster than light...so...

The principal revolved around using two lasers, some how the information was theoretically able to travel faster through the 'connceted beam' from piont A to B than what the light was traveling at.

It had somethig to do with quantum theory ( i remmember reading)

-So the 'spring effect' is not what I am talking about.

I believe you’re referring to a description of “quantum teleportation”.

As the linked to wikipedia article explains, theory predicts that neither this technique, nor any other quantum entanglement-related phenomena, can be used to communicate faster than light (though such a technology, the “ansible”, has long been a staple of science fiction). It does suggest that it may be possible to use quantum teleportation to create 2 identical objects, like the replicators and teleporters on Star Trek, though without the ability to duplicate existing objects, such as people.

I read that article too (in popsci mag)

but this article wasn't about that.

--I really should try and find the mag.
