Space is giant and hence there are numerous possibilities that space is not only an event but also a coordinate system of well-defined geometry. Sometimes, we consider space a “void” and sometimes consider “virtual particles”. But, how one can be serious about its existence? Even we do not know from where space came from, is it came from somewhere or just a perception? However, there are numerous possibilities but we are confined with some limits because we will never know about the existence of space and also why does it exist? But as a traveler, we are more curious to know how space works? May be, there are infinite spaces but our current theory not support that kind of hypothesis. That kind of hypothesis is not only seen in hypothetical books, but also is a best perception / observation about existence of space. At least, we would be able to understand the existence of space, yet this is not possible but one day this would be. But still at that time we would not be sure ab...
