Similarly, time travels slower at your feet than it does at your head. Shorter people actually experience time slower than a taller individual.




I seem to recall watching something about teleportation that solves this. Photons (I think?) operate in couples, separating these will cause one to jump instantaneously through space to rejoin it's partner. The theory is that we can hijack this process and use it to transport practically anything. It's a poor explanation of a theory I saw once, so you'll have to forgive me. We can already accurately predict the position of planets and stars thousands of years in advance anyway.

Personally, unless Hawking gets off his arse (pun intended) and kicks the shit out of the holographic principle (which confuses the shit out of me), and some other smart arse discovers what mass actually is, we'll be no closer to speed of light travel than we are today.

For part one I think I'd heard that before. It's mostly going to be due to the fact the earth is round and that in circular motion the outside of a circle has to move faster than the inside as it has to move a bigger distance around. The smaller the units, the harder it is to get exact predictions. Like my ecology professor used to say, you can accurately predict what the mean temperature will be over a million years, and even what the mean climate will be over that period of time, but when it comes to predicting the weather in terms of daily, you won't get any further than 10 days into the future, with each day in the future being more subject to change. While if you predict the average over those 10 days as a whole, you'll get a more accurate result.

For part 2, I'd never heard of that before. Interesting. But if that's the case, if you separated one, wouldn't it rejoin its partner before you had any chance to move it a long distance? As for the prediction bit, it's true, but if you were off anywhere in the calculation, it could have bad results. Also by accuracy I doubt that means down to the inch and second. In terms of a few megameters to the hour, maybe. but in precise time frames, I doubt it.

Supposedly it is gravity that causes this, you're stumbling into the realm of fractals. Large gravitational forces distort time and space; the closer to the source, the greater the distortion. Since the effects are so miniscule here we aren't aware of it, but it is this principle which causes you to "spaghettify" when attempting to enter a black hole. Gravity pulls on your feet harder than it does on your head, amplify the effect by infinity and you get a mess.

The theory is known as quantum nonlocality. Every particle in the universe is inherently linked, by knowing the properties of one, we automatically define the properties of another. By altering A, B reacts accordingly to reflect this. Instantly. The theory being that every single particle in existence is aware of every other particle. My head starts to hurt if I think about explaining it any further.

As far as measurement goes, I think we've about nailed it as far as planetary movement goes. If the above is true, we probably won't need to.

Edit: Added "the"
Bet you don't know which.

Also of interest, recent research suggests time does not exist outside of the universe. time is a fabric of the universe.

That's just one of the conclusions one may draw from Einstein's theory, anyway. (Since time and space are intrinsically linked, and there is no "space" outside of the known universe, well...you get the idea.) Even weirder, "time" did not exist "before" the Big Bang. ("Before" obviously being meant relatively, here...)

Quote

Also, in observations of incredibly short amounts of time, the laws of physics seem to break down. I read all this about 2 years ago in some article where researchers were using pulse lasers to measure time in 14 attosecond bursts. atto- being metric for quadrillionths. So time measured in 0.0000000000014 seconds.

That's also to be expected, though I'd say that the laws of physics don't break down, but rather our understanding of them. Similarly, Einstein's relativity ceases to hold meaning at extremely small scales, smaller than the Planck length. That time in extraordinarily small quanta no longer follow our understanding of physics is also an extension of the link between time and space, since we've known for quite a while that relativity becomes a poor model for the universe in regards to space at extremely small distances.

Also, please disregard my separate use of space and time. They're the same goddamn thing excepting extreme circumstances (Planck length, Varizen's mention quanta of time), we're just not biologically equipped to think of them as such. Good luck zeroing in on a unified field theory, which present research suggests may lead down a rabbit hole of infinitely recursive, infinitely more complicated, and even self-referential mathematical gobbledygook.. If God is in the details, and the details are infinite...

This double posting shit is really starting to piss me off. I've even replaced my mouse with a spare and reinstalled drivers to see if that would fix it...screw fucking FTL travel, how the fuck do I work my computer?

Your physics don't have a unifying theory for quantum machinations. Time is most likely a construct of quantum interactions. What do?

[treelo]

Blame God.
Write a book about it.
Fuck kids.
Profit.

its a flippin comet/astroid. http://www.france24....4439634-1-0.jpg http://ctein.com/Com...kutake_Coma.jpg they look like that because they are made of ice and when they hit our atmosphere and then speeds up it melts spraying water everywhere and then the water turns into vapor. i can show you 100 of examples if you don't believe me. i dont know why people couldn't figure this out. I'm thinking the world got so boring people needed something exciting to happen so they said "ZOMG ALIENS" also UFO =/= Aliens UFO is an object that is in the air that has not be identified.

Except that it isn't a comet or we'd have known about it sooner. Not to mention that the last time a "comet" came anywhere close to our atmosphere it laid waste to hundreds of miles of Siberia. The trail is actually the vapour created by the sun's heat, and is usually curved as it rotates around the sun (as you can clearly see in your first link); the trail created here wobbles madly as it stretches across the horizon.

Oh, and you can quite clearly see the separation of a multiple-stage rocket at one point.

Were this a one-off thing I still wouldn't consider it a comet given the shape and nature of the trail. Given the spat of similar sightings across most of Asia, it's just those commie bastards scheming again with their highly advanced soviet potato-powered DIY rocket kits.

[Hackysacky]

i don't think that its a separation of rockets. its breaks the sound barrier which as you can see sends a shock wave backwards. and not all comet trails bend. http://www.tqnyc.org...30_color300.jpg http://www.lcsd.gov..../comet_west.gif

and heres a good illustration of what is happening. http://www.cosmograp...InCometTail.jpg

Also the Vapor Trail depends on the temp of the air if its cool it will stay for a long time if its super hot it will dissipate fast.

Sadly for you, it would appear the first link in your original post is of the McNaught Comet, taken about two weeks after it passed the sun. You see, the closer it gets to the sun, the brighter it gets. The only major difference our own atmospheric conditions would make to the thing is if it were cloudy and you couldn't see anything.

The "artist's impression" you give is actually just an overly pretty example of a twin coma. The tail is visible due to radiation from the sun, reversing direction as the comet rounds the sun as the flow of solar wind changes. Even assuming you were right for a moment, let's think about what a large object travelling at about 30,000mph would do when it hits the atmosphere. Oh that's right, heat up. Drastically. That's assuming it doesn't just explode instantly of course. So, by your own flawed logic the trail wouldn't even be visible since at such cataclysmic temperatures it would evaporate fairly quickly.

I mentioned it before and I'll do it again; the last time we think a comet hit the Earth, it laid waste to eight hundred square miles of Siberia. Oh, it didn't even hit the surface either, it exploded in the atmosphere.

And if basic physics wasn't enough, if it were simply a comet someone would have mentioned it by now. I seriously doubt whoever fired it is happy to have t'interwebz gossiping over their latest cock-up. As always, it's "under investigation" and might have "military implications."

It really isn't a comet, go back to physics class. Or just watch some damn TV.

it's clearly not a comet, but you're free to believe whatever you'd like lol

This.

Also, comets are purty.

I think it's time I take my piece of shit mouse out to the tool shed to be beaten. Really regretting pre-ordering FFXIV and Starcraft II instead of focusing on basic computer functionality--like a good mouse.
