it is already open till infinity extent and is still opening!
By their very nature fractals are infinite in extent.
Because it is impossible to determine the extent of the universe because we are only aware of the parts we can see. For this reason, our solar system sits in the very middle of the Earth-visible universe. With regards to the rest of the universe, we are almost certainly nowhere near the center.
Assuming you mean the whole universe and not just the observable universe.No one knows the answer to this question. We are not even sure the universe has an edge. Further it is even unknown if the universe has a finite volume.Possibilities include:A universe with no edges and infinite extent(~volume)A universe with no edges but finite extent ( roughly analogous to the surface of the earth having no edges but finite area)A universe with edges(infinite or not infinite)Many possible universe shapes exist in each of these categories and the universe may exist in more than 3 spacial dimensions further complicating the question. Edges may also exist in some directions but not others.Despite not knowing the answer their are some bounds on the answer considering minimum size and level of local curvature.
the limits of universe are still not defined. until now whatever we know about the limits of universe is because of the light we see. if we keep on receive light from farther distance than that means universe's limits are even beyond. but if we don't receive light from farther distances than that means universe has limits. THIS IS NOT A PROFESSIONAL ANSWER.
It is the idea that the universe will continue to expand forever. By contrast, the closed theory states that gravity will eventually cause the universe to shrink. (I think) In addition to the above. Essentially it is the theory that the universe has no boundary and is not closed in on itself in any way. The shape of the universe in this case must be either "flat" or "curved" to some extent, but not curved enough to form a cylinder, sphere, ellipsoid or torus.
The universe is believed to have no defined upper limit in terms of its size or scope. It is constantly expanding, and the extent of its boundaries is unknown to us.
Super Tengen Toppa Gurren Lagann's size and power suggest it could potentially destroy a universe, but the extent of its destructive capabilities is not explicitly stated in the series. Its attacks demonstrate immense power, capable of causing significant damage on a large scale.
Well, isn't that a beautiful question to ponder? The universe is mind-bogglingly vast beyond our comprehension, so some scientists believe it may go on forever in all directions. Just like with a lovely painting, it's all about exploring the mysteries of the cosmos with curiosity and wonder.
Extent
It is part of the gaming series, to an extent. It's more part of the game's universe rather than a title in the series proper.
The steady state theory was disproved by observations in the sense that at larger distances, the Universe doesn't look the same as nearby. This means the Universe has changed over time, directly contradicting the main assumption of the steady state theory. - I am not sure to what extent quasars were involved, but quasars do tend to show up more frequently at greater distances, i.e., in the early Universe.
