There are a lot of science and physics sites out there discussing questions like "what is time?", "does time exist?", "time travel", and "do you believe in time?" etc.
Some have just general chat, on others you can ask specific questions, others are based on specific topics and videos etc.
Here are some links to forums where I have asked or answered "timelessness" based questions...
(I posted this comment on Professor Sean Carrol's page on time, but unfortunately got carried away so it was too long, and got removed,
so you can see it here)

CreateDebate
CreateDebate "Does Time exist? How?/How not? "
A great site, very professional, you can "support", "dispute", or "clarify" different parts of the ongoing debate.
"Physics StackExchange",
Where I'm asking...
(and)
"DcJunkies"
Very casual chat, warning some colourful language.

"Closer To Truth".
Very professional site.
Lots of good interviews on "time", but every one seems to start from the assumption "time exists", and does not check this.
