jimmyego: FTFA: 74.3 ± 2.1 kilometres per second per megaparsecThough going to The Daily Mail for this information is a bit like using a concussed 3 year old as your science authority,
cman: Can someone dumb it down even more? Difficulty: so even I can understand it. I know, its hard, but please, I want to play with the big boys, too
cman: Anyone think the rubber band theory (the big crunch) is a possibility?
Kanemano: cman: Can someone dumb it down even more? Difficulty: so even I can understand it. I know, its hard, but please, I want to play with the big boys, tooThe universe itself keeps on expanding and expandingIn all of the directions it can whizzAs fast as it can go, the speed of light, you knowTwelve million miles a minute and that's the fastest speed there is
simplicimus: cman: Anyone think the rubber band theory (the big crunch) is a possibility?It looks more like we're heading to the heat death.
picturescrazy: The thing that I don't get is that we can see almost as far away as there universe is old (makes sense), but in every direction? How does that work?
ZAZ: I'm sure there's a plot of Hubble constant vs. time out there but I can't find it. In 1930 it was 500 km/s/Mpc. There was a series of major corrections (oh, there are two kinds of Cepheid variables, we'll have to make the universe bigger). Around 1990 there was a young universe 100 km/s/Mpc faction and an old universe 50 km/s/Mpc faction. Some time after I was in school the sides got together and split the difference between their estimates.
Lava_Backflips: I am in our system and in a ship going away from our sun. I am going 2 times the speed of light and hold a mirror up one foot in front of my face, what do I see in the mirror?
Harry_Seldon: Lava_Backflips: I am in our system and in a ship going away from our sun. I am going 2 times the speed of light and hold a mirror up one foot in front of my face, what do I see in the mirror?You can never go faster than the speed of light based on our current understanding of physics. This seems to be a constraint built into the this Universe, and not likely to change. (but you know that and a making a joke).
OriginalGamer: Lava_Backflips: I am in our system and in a ship going away from our sun. I am going 2 times the speed of light and hold a mirror up one foot in front of my face, what do I see in the mirror?Speed is relative, so assuming you we're holding the light source creating your reflection, you'd see your face.I could be wrong though, it's kinda wibbly wobbly timey wimey.
IronTom: The universe is expanding so fast, that the things that are far away from you look small because at the time that the light left them to get to your eye, they actually were that small. For instance that TV over there./no?
MartinD-35: My first thought when I read about the end of entropy was that our actual reality is we are being sucked into some kind of giant black hole. ....
RockofAges: justtray: Okay a couple things not mentioned.It may not be that the universe is expanding that fast, but it may be that our area of space is moving very quickly, throwing off our readings. I'm not sure how far this space telescope has to be to minimize that effect.Semi related to that - faster than light travel is sort of possible. If the universe's expansion is accelerating, two objects going in opposite directions could at some point appear to be moving away from one another at faster than light speed, essentially causing those bodies to disappear from our visible view.Also, this conspiracy article strongly suggests that the DoD has already developed FTL communication. http://astroengineer.wordpress.com/2010/04/07/a-curiosity-of-spirit-fu ll-document/A quick wiki search shows that there is indeed FTL communication being tested on Earth, and has been reported to be successful at a range of 89 miles. http://en.wikipedia.org/wiki/Quantum_teleportationAs for how we could move objects at faster than light speeds, it would have to involve some type of manipulation of "dark energy," whatever that is. If you could negate the accelerating expansion effect in the area around a spacecraft, you could in theory achieve relative faster than light travel to some object by the same principle that would cause them to disappear from our view, as explained above. However, since we don't even really know what dark energy is, that could be a long way off.Not a scientist, but I did stay in a Holiday Inn Express last night.Did you say FTL?/Just got the Engi ship. This game is HARD but enjoyable because of that.
darthdrafter: MartinD-35: My first thought when I read about the end of entropy was that our actual reality is we are being sucked into some kind of giant black hole. ....That's what I was going to say. Maybe all that space stuff isn't flying away from us faster... maybe we're falling into the gravity well faster./Help! I've fallen (into a black hole) and I can't get up!
