Question about inflation theory
Recently, new results were released from NASA's Wilkinson Microwave
Anisotropy Probe (WMAP) satellite, launched in 2001 to measure the temperature of radiant heat left over from the Big Bang, which is the theoretical beginning to the universe. The new WMAP observations, announced at a NASA press conference today, reveal what the universe was like in the first trillionth of a second after the Big Bang. From the microwave background, researchers teased out a new signal called the "polarization signal." According to the conclusions of this report, during this growth spurt, a tiny region, likely no larger than a marble, grew in a trillionth of a second to become larger than the visible universe. Well, I'm confused. According to Einstein nothing can travel faster than the speed of light. If that is true, how is it that the universe expanded from the size of a marble to something large than the visible universe in a trillionth of a second? I'm neither an astrophysicist nor a physicist, which is why I'm asking this question here. And please be kind, as my calculus is a little rusty these days. Any thoughts? George |

Question about inflation theory
The basics of Inflation theory is that SPACE itself moves, so the
question about travelling Faster Than Light in Special Relativity does not arise. The thought that I have though is that if FTL is possible when expanding into empty space, but not possible at other times, must mean that there is some entity which will either allow or prohibit FTL. http://groups.google.co.uk/group/sci...0c1c2454c99cd1 Read my comments on this thread rather than those of other people. To me Inflation must either mean an FTL particle - or a multdimensional geometry which itself sets Inflation off. |

"... a trillion trillionth of a second" Well, I'm confused. According to Einstein nothing can travel faster than the speed of light. Right. You can't apply enough energy to an object to get anywhere near c. If that is true, how is it that the universe expanded from the size of a marble to something large than the visible universe in a trillionth of a second? No explosion. No energy required. No massive particles involved (since none of the "four forces" had congealed yet). Simply an adjustment in the distance between all "bits" of energy. I'm neither an astrophysicist nor a physicist, which is why I'm asking this question here. And please be kind, as my calculus is a little rusty these days. Any thoughts? It is what the data points to, couched in the Standard Model. Stay tuned! More sights to be revealed. I'd vote for Ernest Wittke building another EinsteinHoax page. David A. Smith |

Question about inflation theory
CeeBee a écrit :
The misunderstanding is that space itself expands. Everything inside the universe seems to be bound to the lightspeed as a maximum, but "the universe" itself (space) isn't bound by speed restrictions predicted by theory. After all, according to what reference would you measure the "speed" of space when it is expanding? SPACE itself expands ????? Sorry but INTO WHAT would space "expand" ???? I would bet that it would expand into... more space isn't it? This is just nonsense. But imagine for a moment that space is "expanding" faster than light, as proposed by this wonderful "inflation" theory. Since no object can go faster than light, NOTHING MOVES and all objects in the universe have negative speed: point a point b object x -- Object "X" starts moving at some speed smaller than "c" to point b, say, at 50 Km/sec. In one second object x has traveled 50 Km, but the distance between a and b has increased by more than 300 000 Km since space is "expanding". This reasoning is valid FOR ANY POINT A AND B. Then, object X will NEVER reach point b, nothing in the universe can move at all, the temperature of the universe is below absolute zero. Why? At absolute zero objects do not move at all. But since space is expanding, the speed of every object in this universe is negative (the object is flying AWAY from all other objects in the universe) All this is quite comic. Space is "expanding". Yeah. And I am getting younger every day. jacob |

... a écrit : The basics of Inflation theory is that SPACE itself moves SPACE moves ???? Excuse me but... WHERE would space move into ????? I bet it would be into more space since MOVING means changing one object's coordinates. SPACE itself can't move at all, since SPACE is not an object at all, you are dreaming. SPACE can't move. TIME can't accelerate... How much nonsense is possible to hear??? He meant Space expanding (not moving) faster than light. Luigi Caselli |

Question about inflation theory
Dear jacob navia:
"jacob navia" wrote in message ... George Dishman a écrit : Releativity says an object cannot travel through space faster than the speed of light in vacuo, but that doesn't stop the sapce between objects expanding at a rate such that the distance between them increases faster than that speed. SPACE itself expands ????? Yes, as defined by international decree. Sorry but INTO WHAT would space "expand" ???? NOT "into what", but "between what". Without matter/energy, there is no space. Space is simply a spreadsheet on which the laws of physics play out, and any value can be obtained. I would bet that it would expand into... more space isn't it? This is just nonsense. Your question is nonsense, yes. But imagine for a moment that space is "expanding" faster than light, as proposed by this wonderful "inflation" theory. Since no object can go faster than light, NOTHING MOVES and all objects in the universe have negative speed: point a point b object x -- Object "X" starts moving at some speed smaller than "c" to point b, say, at 50 Km/sec. In one second object x has traveled 50 Km, but the distance between a and b has increased by more than 300 000 Km since space is "expanding". Right. And you perceive a problem, where? Note that we aren't talking about motion, when we talk about either "inflation" or "expansion". Think instead of what inflation in an economy entails. When there is inflation, what are the goods and services expanding into? See? This question makes as much sense as your does. .... All this is quite comic. Space is "expanding". Yeah. And I am getting younger every day. A truly hackneyed response. Don't you get tired of living in a reality that you find entirely comfortable? Don't you feel the least bit of regret at leaving the host of facts that don't agree with your personal beliefs out in the cold? Where do *you* personally find wide-eyed wonder, jacob? David A.

George Dishman a écrit : Releativity says an object cannot travel through space faster than the speed of light in vacuo, but that doesn't stop the sapce between objects expanding at a rate such that the distance between them increases faster than that speed. SPACE itself expands ????? That is the common way of expressing it. Sorry but INTO WHAT would space "expand" ???? It is not embedded in some more fundamental manifold, space isn't "in" anything. I would bet that it would expand into... more space isn't it? This is just nonsense. It is indeed. But imagine for a moment that space is "expanding" faster than light, as proposed by this wonderful "inflation" theory. Since no object can go faster than light, NOTHING MOVES and all objects in the universe have negative speed: Don't confuse SR and GR, the limit is local. Consider a galaxy we can see perhaps 10 billion light years away. Space between us and it is expanding so the distance is increasing at a significant proportion of the speed of light. However, light within that galaxy is moving past its stars at the speed of light relative to those stars in all directions. point a point b object x -- Object "X" starts moving at some speed smaller than "c" to point b, say, at 50 Km/sec. In one second object x has traveled 50 Km, but the distance between a and b has increased by more than 300 000 Km since space is "expanding". This reasoning is valid FOR ANY POINT A AND B. The reasoning is valid only for objects sufficiently far apart, the speed is proportional to the distance. Then, object X will NEVER reach point b, ... Correct, it is called a "horizon". ... nothing in the universe can move at all, No, object x is still moving relative to a. the temperature of the universe is below absolute zero. Why? At absolute zero objects do not move at all. But since space is expanding, the speed of every object in this universe is negative (the object is flying AWAY from all other objects in the universe) All this is quite comic. Indeed, your ideas are bizarre. Space is "expanding". Yeah. And I am getting younger every day. Perhaps that's true, your infantile response appears to confirm it. George |
