Ask yourself does if ∞+1=∞ then does ∞/∞= either ∞ or 1
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.
If our Universe were infinite both in size and age, then our entire sky would, by necessity, be filled with light at all times. That it is not is Olber's Paradox -- and indication that our Universe must be finite in either size or age. The Big Bang was a hypthesis that it was finite in age; and every prediction made by the BB that has been tested has supported the hypothesis.
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.
The universe people think is infinite but in albert enstien general therom of relativity there might be enough mass to close the universe but not in a circular shape but in a oval shape as there isnt enough mass to make it circle but enough to make it oval and it is not infinite as it is 164,000,000,000 light years wide or 50 gigaparces
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}.
