Mathematically, it's called an "open" universe.
As best we can tell as of now, our Universe is open.
If a universe is coasting, it means it is expanding at a constant rate and will continue to do so forever without accelerating or decelerating. This expansion will result in the universe becoming increasingly larger over time.
Scientists predict that the universe will continue to expand forever based on observations of the universe's current rate of expansion, known as the Hubble constant, and measurements of the universe's overall density. These observations suggest that the expansion is accelerating, driven by a mysterious force called dark energy, which counters the effects of gravity and pushes galaxies further apart.
It will continue to expand
The generally accepted model is called the "Big Bang". It means that all the matter and energy of the Universe was in a tiny space, some 13.8 billion years ago or so, at a tremendously high temperature and density. From there, it started to expand; currently, the Universe continues expanding, and will probably continue to expand forever.
It's just called the expanding universe.
Scientists predict that the universe will continue to expand indefinitely, eventually becoming cold and dark in what is referred to as the "heat death" scenario. This will occur as all stars burn out, leaving behind remnants of galaxies and black holes.
The theory is that the universe 13.5-14.0 billions year ago was infinitely small but expanded very rapidly after the big bang.e.g. an expanding universe could1) expand until it reaches a size where it starts to contract2) expand forever but the speed of the expansion slows down in time until the expansion is almost not measurable3) expand forever at a fixed rate4) expand forever at an increasing rate (gets bigger, faster)The current theory is that the universe continues to expand and does so at an increasingly fast rate (e.g. item 4 above)Therefore, the best answer to your question is yes: the universe is truly infinitive because it will continue to expand and this expansions will be faster and faster the more time that goes by.
No, the market would not continue to expand forever; it would stop growing when the market expands to its limits, and it runs out of unused resources.
It's called the "Big Bang Theory." There's evidence that the universe is expanding, which means it all had to start from a single point. What caused this event is up for debate, as well as whether the universe will continue to expand forever, or reach a point and stop, then come back in on itself.
According to the general theory of relativity, the ultimate fate of the universe depends on its density of matter and energy. If the density is above a certain critical value, the universe will stop expanding and eventually collapse in a "Big Crunch." If the density is below this critical value, the universe will continue to expand forever. Current evidence suggests that the universe's expansion is accelerating, indicating a low density and a future where it expands indefinitely.
This question has been giving nightmares to cosmologists for years.But with the current evidences, scientists have determined that the universe is expanding at an ever-increasing rate and it will expand forever.
Closed: Is where there is sufficient gravity to halt the expansion of the universe, after which is slowly starts to contract until "The Big Crunch".
