I heart science. One of my favorite sites is sciencedaily.com

Galaxies do NOT travel FTL.

The space that contains them is expanding.

When you go to the airport, and get on the people mover conveyors (horizontal escalator), by not walking, you are moving at walking speed to an observer, even though to every one else on the conveyor, you are standing still. Then when you decide to begin walking, you are walking speed X2.

Same with galaxies in space. The space is expanding, and the galaxies also have their own velocities.

I believe there are things that travel faster than light, however since our bodies cant see/sense those types of 'things' we have to build something that can detect those types of things, but they are on a complete different plane of existance than we are it would take a extreme discovery of those 'things' (i say things cuz dunno what other terminology to use, particles maybe?)

think about it but use a slower object... if we only saw sound waves, and could only detect sound waves then we would think the fastest thing in the universe would be sound waves. Then in that world, the discovery of 'light particles' would be a HUGE discovery and its on a different plane of existance (light vs sound)
I highly doubt that we have discovered all the basic 'particles' of the universe, being that it is extremely vast and we have yet to truely master space travel outside of our orbit, let alone our solar system then to the galaxy, who knows what else is out there. we can 'see' light from distant stars which are millions of light-years away because the light particles have a direct, non obstructed "line of sight' to our planet. so we know there is alot out there, but what about the forces that take the light's path away from earths view?

love this kind of stuff

You guys do realize they have recorded material that has traveled faster than light, which means everything we know is now false

That wasn't confirmed yet. Only one group of scientist observed it and the recorded times were barely out side the margin of error. And it was a neutrino that did it.

It did happen but still yet to be consistently verified...if it is then were back to square 1.

Glad to see some of you guys liked some of the videos posted here.. I will be posting a few more from my youtube collection.

Times, good to see you around man! In regards the FTL comment, in all honesty, I have no dogs in this race. However, depending on the medium used to "measure" the relative distance between two interstellar objects, speeds FTL can be "calculated" but not observed.. At least, not with the existing technology to measure speeds, etc, that mankind has at the moment.. The following is for your information:

"Can objects move away from us faster than the speed of light?
Again, this is a question that depends on which of the many distance definitions one uses. However, if we assume that the distance of an object at time t is the distance from our position at time t to the object's position at time t measured by a set of observers moving with the expansion of the Universe, and all making their observations when they see the Universe as having age t, then the velocity (change in D per change in t) can definitely be larger than the speed of light. This is not a contradiction of special relativity because this distance is not the same as the spatial distance used in SR, and the age of the Universe is not the same as the time used in SR. In the special case of the empty Universe, where one can show the model in both special relativistic and cosmological coordinates, the velocity defined by change in cosmological distance per unit cosmic time is given by v = c ln(1+z), where z is the redshift, which clearly goes to infinity as the redshift goes to infinity, and is larger than c for z > 1.718. For the critical density Universe, this velocity is given by v = 2c[1-(1+z)-0.5] which is larger than c for z > 3 .

For the concordance model based on CMB data and the acceleration of the expansion measured using supernovae, a flat Universe with OmegaM = 0.27, the velocity is greater than c for z > 1.407. "

General Relativity says no Quantum Theory says maybe. I have no clue...

the jury is still out on that one mate.

give it some time, let some other teams replicate the results and draw their conclusions.

the speed the neutrinos where traveling FTL were just a hair bredth whisper above light speed. I say lets' wait until more data comes in.

nice, i used to spend hours out in the winter nights with a scope, would love a go on one of those mega scopes!

^ I've done it a few times when i was younger Dec. Mostly what I remember are the dots of light (stars) being bigger, yet with no additional detail. Also, friggin cold at night at 12,000 feet up. And it takes aloong time to drive up there on those windy mountain roads. There's really not much to see in real time. the really fantastic things to see nowadays are computer enhanced and time reduced.

yeah, true on that. i rem a shooting star whizzing past my view once, scared the shit outa me lol and once an army helicopter started descending towards me and hit the fvckin lights, standing in a field in Northern Ireland near a soldier drop off with a long tubular object pointing skywards can be bad for your health lol

about 15 years ago or maybe a bit longer, i heard that there would be a meteor shower, supposed to be a good one. so around midnight, i got my lawn chair out, laid back, jug of wine at the ready, and watched. I saw dozens of meteorites. A variety of colors, reds, blues, whites.... a big red one came down, split into two, and continued on... very bright. A big blue one came down, and kinda exploded or powderized, and what once a large blue streak, somehow turned into more of a shot gun blast with a zillion little tiny ones. Pretty cool.

Astro Physics was one of my favorite subjects. i'll try and gather some of my brain cells and post some interesting info & topics

Sounds cool, I have not seen any that good, only the typical every year or two meteor shower where you just see the typical series of shooting stars but ti's still cool sitting out in the hot tub with some wine and the female of choice watching all the streaks in the sky. It usually leads to more than one full moon.

^ Oh, everything with you leads to orgies with hotties!


.....That's it! I'm moving back to ASIA!!!
