Does Evidence of the Afterlife Exist?

We can imagine that other dimensions exist beyond our own 3-dimensional world. Unfortunately, we have no way to directly observe those domains, it's impossible. However, sometimes a tear in the fabric of time & space casts a shadow in our world that dimly reveals truths about what lies outside of our universe.
Take for example the tesseract featured in this event's image. It is the shadow of a 4-dimensional hypercube, analogous to a two-dimensional square or three-dimensional cube. It's usually rendered in continuous motion folding in upon itself (animated gifs don't work in Meetup). By observing the shadow, we can understand some of the properties of the object, but only in a limited way.
In this event we will discuss what constitutes acceptable evidence. There are religions, theories, conjecture, and speculation that try to explain the hereafter, I reject blind faith; show me some good evidence.

Please note: This meeting will present the same information as the first event. If you attended a previous meeting there is no need to join this one.
