Predictions from theoretical math.<quoted text>
Another type of infinity arises in gravitation theory and cosmology. Einstein's theory of general relativity suggests that an expanding Universe (as we observe ours to be) started at a time in the finite past when its density was infinite — this is what we call the Big Bang. Einstein's theory also predicts that if you fell into a black hole, and there are many black holes in our Galaxy and nearby, you would encounter an infinite density at the centre. These infinities, if they do exist, would be actual infinities.
You should stick to football and the constitution, Goofus.
Have all your infinities you want in theoretical math.
In physical reality, I proved you can have none. By definition.
"Infinity and zero are abstract mathematical constructs which we use to describe what a system is tending towards. The mathematical philosophy behind this is not too difficult to grasp because these abstractions are unrealisable by self-definition."
"As with many physics theories, infinity is only a concept that fixes certain problems. In the literal sense it may not, and in the case of infinity, does not literally exist in nature. Since the universe had a beginning, it cannot contain infinity."
