Do you think the universe is ripping (itself) apart? Soon to collapse in on itself?

Answer 1

There are really two things happening here. Bodies like the earth and moon move away from each other over time. This weakens their gravitational pull on one another. So objects pull away farther and faster as time passes.
The metric expansion of space is a key part of science's current understanding of the universe, whereby spacetime itself is described by a metric which changes over time in such a way that the spatial dimensions appear to grow or stretch as the universe gets older. It explains how the universe expands in the Big Bang model, a feature of our universe supported by all cosmological experiments, astrophysics calculations, and measurements to date.
The expansion of space is conceptually different from other kinds of expansions and explosions that are seen in nature. Our understanding of the "fabric of the universe" (spacetime) requires that what we see normally as "space", "time", and "distance" are not absolutes, but are determined by a metric that can change. In the metric expansion of space, rather than objects in a fixed "space" moving apart into "emptiness", it is the space that contains the objects which is itself changing. It is as if without objects themselves moving, space is somehow "growing" in between them.
Because it is the metric defining distance that is changing rather than objects moving in space, this expansion (and the resultant movement apart of objects) is not restricted by the speed of light upper bound that results from special relativity.
The raisin bread model imagines galaxies as raisins in a raisin bread dough that will "rise" or "expand" when cooked. As the expansion occurs, each of the raisins gets farther from each of the other raisins while the raisins themselves stay the same size. The dough between raisins in this model acts as the space between galaxies while the raisins as "bound objects" are not subject to the expansion. This model is useful for explaining how it is that a standard ruler can be determined for measuring the expansion. In an empty universe, space serves as the only ruler and as rulers expand with space, there would be no way to distinguish between an expanding universe and a static universe. Only in a universe where there are objects which are bound and do not expand so that the rulers are independent of the expansion can the metric expansion be measured.
Like the ant on the balloon model, this model also suffers from the problem that the raisin bread is expanding into the pan. To make the analogy to the universe, it is necessary to imagine raisin bread that has no observable edge. Expansion would still occur, but the question "what is the raisin bread expanding into?" would be meaningless.
I don’t know that it will tear its self apart. I think this because if the universe is infinite then there are potentially an infinite number of black holes. On an infinite time scale At some point the moving matter should be absorbed by the black holes.

Answer 2

This depends on what you mean by "ripping itself apart".
Philosophically, if there is a 'tear" in the universe and stuff can "spill out" through the tear, the universe is simply its previous boundary plus the volume of the spilled stuff. So in that respect, it can't rip itself apart.

Most indications are that the universe is expanding, and physicists have argued whether the universe can go on doing this (apparently forever) or stop somewhere and start contracting. Most betting is on the first alternative.

Answer 3

Time isn't dependant on area. Time is portion of spacetime. You actually won't be able to separate area and time, they seem to be a similar 'ingredient'. out of your aspect of view, in case you count number to 5, it truly is going to take 5 seconds, sure. If, besides the undeniable fact that, you're transferring faraway from someone at just about the speed of light, to them it truly is going to take a lot longer than 5 seconds. there became no time previously the massive Bang, and no matter if it kind of feels intuitive or now to not you, it truly is in reality the point of foundation. the massive Bang did not only precipitate count number and power, it prompted spacetime itself. you're asking tremendous questions, yet they educate a foul lack of diagnosis on the challenge. save interpreting. ------------------------ "ok...Can someone clarify what "enviroment" the massive bang got here about in, if it didnt ensue in "area"?" In some hypotheses, it did not ensue everywhere. In others, it truly is basically a small subset of a larger set of places. Your question boils right down to "the position is the universe?" to which the answer is, relies upon on which speculation seems to be the right one.

Answer 4

I do get that feeling,..maybe more of an expanding, stretching feeling though...and that feeling was especially acute recently when I was reading a novel called the curious incident of the dog in the nighttime, as the narrator reflects on his understanding of the universe..

Answer 5

no..i don thnk d universe itself is ripping apart.....but only d galaxies r xpandin n der wil b at one point of time ,nothing in d universe. ....all energy wud b used up....

Answer 6

the events are already set in motion in which all matter which we know of will eventually disintegrate into nothingness

Answer 7

Hi. Soon? No.

Answer 8

no
