The purpose of this article is to introduce the basic concepts of 
what GR is about, without getting lost in mathematics, but also 
without succumbing to the “easy way out”, as given by seemingly 
simple yet highly misleading visualisations such as the ever so 
popular “rubber sheet analogy”. It is to be understood as a plain 
text, “first primer” type of introduction. This article is aimed at 
the interested lay audience with little or no mathematical 
background, so I will sacrifice mathematical rigour for clarity and 
understanding; the mathematical side of GR will be presented in a 
future article. While the finer details of GR are undeniably hard, 
its basic principles are simple, and can be understood by anyone.

Let us first of all recall a few important points from our 
discussion of Special Relativity – if you haven’t read the articles 
linked to above, I would urge you now to do so:

1.An event is a point in space at an instant in time

2.Space-time is the collection of all events

3.The geometry of space-time is the relationship between events, 
i.e. of the relationship between measurements of time and space 
taken at different places and times

4.In the absence of gravity, space-time is flat, and is described by 
the laws of Special Relativity

5.Time and space have no universal meaning, they are 
observer-dependent concepts
