Can you explain the "Maha Meru"?

I have come to learn the fact that the idea if maha meru is not only included in the buddhist canon but in many other beliefs and cultures which are not Buddhist. This is what Wikipedia says - https://en.wikipedia.org/wiki/Mount_Meru I belong to the theravada tradition so i am very interested in knowing sources in the canon for further learning if you can mention some. Also if you can ease me into the topic with a small explanation it is also very much appreciated. > *I know that this has nothing to do with nirvana but i am curious of this and i also read this* > > https://muslimanswersfiles.wordpress.com/2013/05/01/buddhism-modern-science/ I guess i want an answer to the question "While all other things are logical and also even scientific, why this (Maha meru) makes no sense?" Namo Buddhaya!
