This is denoted by adding "i" to the numbers. It is the square root of -1 (multiplied by your number I suppose)

It is considered to be a mathematical tool that as it turns out justifies the universe having NO beginning. It also smoothes out issues re Black Holes.

It has been explored conceptually/ mathematically by Hawking and er (I must look up the name of the other person) concerning their main interest - Black Holes. It also removes the need for a Singularity.

As many posters debate the origin of the universe and the singularity in Black Holes I thought I really should post something on the subject - especially as Time itself is of considerable interest to me. I confess to knowing next to nothing about Imaginary Time except it is supposed to be perpendicular to space as a spatial dimension. I am not sure if it is mathematically used as a substitute for 'normal' time or as an additional time.

Maybe there are people here that know what they are talking about on imaginary time (?)
