Dark Matter and the age of the universe (13.8 billion years????) fieldofforce: We know that whatever "dark matter" (for lack of a better name for now), is, it warps space time. And consequently because it is estimated to be 25% of the stuff of the universe, the spacetime warping (gravity) that it creates has a large effect on time (motion, movement, change, etc.) It would seem to follow that our present estimates of the age of the universe (13.8 billion years) are considerably off. fieldofforce: Ineq: point taken. How much more influence on the age of the universe does dark energy have considering that it is 70% of the universe. Evelyn99: I think dark matter is just a name for an acceleration that we don’t know much about. Perhaps the minimum vacuum energy that is in every square inch of the universe. Kinda interesting that is the space itself and not the mass within it that accelerating. Could perhaps be a force not belonging to our traditional universe but rather some influences from a parallel universe.? Don’t think humanity will ever know because so much of the universe is expanding faster than the speed that gives us what we call the visible universe Harryhd: Yeah they name it that because of its influence on gravity & the laws of physis we currently understand. If youve seen pics of stars galaxies etc where things are like looking through water bendfing the visible light..say a star in front of the object your wanting to see, the light bends & the pic of what it should look like is calculated and then shown. U follow? I was wondering if the fartherest galaxies that we see the light of are 13.7 billion light years. How far are they ' actually away from us today'? kittybobo34: I wouldnt think the expansion of the universe or the speed of these other galaxies is very high compared to the speed of light. So if we see light that took 13.7 light years to reach us, its present position would be perhaps 14 light years away now. Of course it all depends on what star or galaxy we are looking at. kittybobo34: Somewhere around 13.8 billion years, of course that is assuming time is constant, which we know it isnt. Evelyn99: Well we only see the so called visible universe. That’s only a fraction of the universe. Some parts will never become visible ever. When we observe the edge it’s where light has reach us but there is no edge. Our expansion is about 13.7 ish billion years but something triggered the universe to expand so there must have been something perhaps other univers that had a collision maybe that is something that happened from time to time. Who knows. kittybobo34: I agree Evelyn, I have always thought that there may be multiple universes out there at distances we cant even imagine. All dead giant black holes, which would explain the accelerating expansion of our own universe. When one universal expansion collides with another, you have enough matter in the form of a super colossal black hole to trigger the explosion and expansion of a new universe. My pet theory. kittybobo34: They say our universe is 13.8 billion years old, because thats how far we can see in both directions.....apparently it hasn't occurred to them yet that we may not be in the middle. OR, that time may not be constant. afencewalker: they probably screwed up on dark matter, but they definitely screwed up on dark energy. the oldest data is of the youngest parts of the universe, and they are the fastest. everything after that is slowing down over time. there is no dark energy and we are decelerating, not accelerating. kittybobo34: hmmm Haven't seen anything that would go counter to the accelerating universe as yet. But I tend to agree about Dark energy. David Nathaniel: "BLACK holes" "DARK matter" these terms follow a malevolent masonic agenda to frighten and belittle. God laughs at them incessantly. "Dark matter" is the vain musings of the pseudo-scientific community which is a religion in itself requiring faith in its "theories." Exceedingly dark indeed!
