Is the square root of infinity bigger or smaller than infinity?

smaller imo
ETA: I know people will say sqart(infinity) = infinity which is true, but just saying theoretically infinity>1 and the square root of any number > 1 is less than the starting number.

Really, infinity isn't a number, it's like asking, "What's the square root of an apple?"

^ What papa said. It's a mathematical concept, not a number

Yep, gotta agree with albinopapa

I'm pretty sure any root of infinity is infinity, because of the logic of the infinity concept of real numbers' extension.

Infinity is introduced in infinite series math and is also called uncertain limit. It is one of the answers to a question  does the particular series converge? There are 3(I don't know maybe more) answers to this question: 1.) Yes they converge to a limit. 2.) No they diverge uncertainly(for example jump between numbers 1 and 1) 3.) No they certainly diverge to uncertain limitNow correct question that you are asking would be: Does a square root of certainly diverging series also certainly diverge ? The answer is yes(and if i translate it to your question then no)  and proof to that is the so called minor criteria which is an analogy of major criteria(a method of comparison between series which converge to zero). I am not going to explain this madness here in detail  if you really wish to know you should read an academic text about mathematical series  I can provide a link if you are fluent in german. Incredibly enough there is a direct visual proof of what you ask here in Chili's tutorial series  it's in old beginner tutorial 9. The pattern would have rings regardless of whether one uses square or root value of the distance. It does however affect the distance between rings aka divergence zones . You can see my explanation on this thread.

Yeah, I was going to say the concept of inifity only really makes sense in the context of limits.
