UNIVERSE

Lately, everytime the word UNIVERSE comes to my head I get frustrated because I can´t understand what does it means on its totallity. By searching on google, it says that " The Universe comprises everything that physically exists, the entirety of space and time, all forms of matter and energy, and the physical laws and constants that govern them. However, the term Universe may be used in slightly different contextual senses, denoting such concepts as the cosmos, the world, or Nature." I understand that the meaning of Universe is everything, however, the part that the universe is infinite is the part where I don´t understand, but at the same time I do because ok; maybe it has an end, but what is after that end. This is very confusing and I also think it is amazing how everything was formed exactly in order to exist. We survive thanks to the food there is, that food exists because water and other factors, etc. I really hope someday we get a reasonable answer!
