how come that the universe is going away from us in all directions, should not at least one direction be going the same way as us, unless we are really the centre of it all, alun

It wouldn't be expanding then, would it? It'd be crunching to the left and expanding to the right.alun2504 wrote:how come that the universe is going away from us in all directions, should not at least one direction be going the same way as us, unless we are really the centre of it all, alun
We are the center of it. Every point is.alun2504 wrote:how come that the universe is going away from us in all directions, should not at least one direction be going the same way as us, unless we are really the centre of it all, alun

Not knowing everything doesn't mean that we don't know a lot, and know it well. Science is about seeking the answers to mysteries, not letting them be. You're in the wrong forum here.alun2504 wrote:seems to me that when they cannot find an answer they make up hypothetical mysterious answers, think i ll just let the mystery be, until i go and find out the answer for myself alun

He hoped to solve the horizon problem in a natural way by showing that the early universe underwent an oscillatory, chaotic epoch. Misner hoped that the chaos would churn up and smooth out the early universe. Also, during periods in which one direction was static (e.g., going from expansion to contraction) formally the Hubble horizon H−1 in that direction is infinite, which he suggested meant that the horizon problem could be solved. Since the directions of expansion and contraction varied, presumably given enough time the horizon problem would get solved in every direction. While an interesting example of gravitational chaos, it is widely recognized that the cosmological problems the Mixmaster universe attempts to solve are more elegantly tackled by cosmic inflation.>>Click to play embedded YouTube video.

Well, that's a breath of fresh air. I see a lot of people reminiscing over the last century and wishing it was "like the good old days" again. I couldn't disagree more with that sentiment! As long as we don't annihilate ourselves somehow, things are constantly looking better for humanity. I have to stay positive and hope that we'll avoid the worst case scenario with global warming somehow, but other than that...alun2504 wrote:. . . but the next one should be even better
