Those lists are both infinite. If you could specify a range, it would be easier.
The question of whether the universe is infinite is still a topic of debate among scientists. Some theories suggest that the universe could be infinite in size, while others propose that it may have a finite boundary. More research and observations are needed to definitively answer this question.
Olbers' Paradox questions why the night sky is dark if the universe is infinite and static. The resolution to this paradox is that the universe is expanding, which is a key aspect of the Big Bang theory. The expansion of the universe causes light from distant stars to redshift away, making them too faint to illuminate the night sky.
The question of whether space is infinite is still a topic of debate among scientists. Some theories suggest that space may be infinite, while others propose that it may have a finite size. Further research and observations are needed to definitively answer this question.
The three differ in their extent. Lines are infinite in both directions. Line segments are finite: they have two well defined end-points. Rays are finite in one direction, infinite in the other: it has one end-point and stretches to infinity in the other direction.
There are theories, such as the multiverse theory, that suggest the existence of multiple universes beyond our own. These universes may have different physical laws, constants, or dimensions. However, the existence of these other universes is currently speculative and has not been definitively proven.
ummmm, galaxies can have galaxies in them unless they combine, also, we don't know, the universe is infinite and we have ye to see beyond our local galaxy cluster... sorry but that is an impossible question (although if the universe is infinite then nothing is quite impossible...)
It can't, at least one of those two suppositions must be false; possibly both.
Isn't that just the most fascinating question, friend? Picture this: space is like a never-ending canvas with endless possibilities. We may still have corners of the universe waiting for us to explore and reveal their wonders, just like little surprises hidden in a happy little painting.
Einstein never made any such calculation. Even today the total size of our Universe is speculative at best. Einstein speculated it was infinite in both size and age.
Yes. Remember that rectangles and squares are both parallelograms. Square tiles are the most common. The next most common are rectangles. Both shapes can tessellate finite planes. Other parallelograms can tessellate infinite planes (or finite ones if you allow parts of the parallelogram along the edge of the plane.)
Easily. Indeed, it might be empty. Consider the set of positive odd numbers, and the set of positive even numbers. Both are countably infinite, but their intersection is the empty set. For a non-empty intersection, consider the set of positive odd numbers, and 2, and the set of positive even numbers. Both are still countably infinite, but their intersection is {2}.
