So I was wondering how Hammocks support the weight of the user when the type of threads used only hold around 30lbs tensile strength.
Hope someone can answer my question.

I think it has to do with the amount per square inch of the threads collectively, not one thread. Someone else will chime in hopefully....

"Bless you child, when you set out to thread a needle don't hold the thread still and fetch the needle up to it; hold the needle still and poke the thread at it; that's the way a woman most always does, but a man always does t'other way."

lol this is great Rev Thanks for the smile.
Yes bumble bees can fly (and they have proven how somewhat 'recently'... uses turbulence as opposed to standard lift if I recall what I read)
And yes you don't fall through a hammock because of the distribution over thousands of these threads... just like a million ton suspension bridge doesn't fall down even though the individual steel threads only hold a few thousand pounds each... cause there are thousands of them
breaking strength depends on the moment of force (static force). If the force involved is dynamic (i.e. me rolling about trying to find the sweet spot) it can be many times higher than your actual weight. Also keep in mind the angles! A hammock is a suspension system, so there are angles coming into play (i.e. it isn't a string holding a weight hanging straight down). Generally, the flatter the hang the higher the forces involved. As you approach "perfectly flat and super tight" the force approaches infinity (theoretically). In practice things just break as you do this

Hmm, I'm sure this is a case for trial and error. I may hurt my back in the process D:

Ohhhh wait... I think I misunderstood your question!!
Are you talking about thread-count of the fabric (general "I'm curious" question) or stitches-per-inch (practical application question) and thread type for sewing??
If a sewing question I'm sure many of the people who make their own gear here can give you some great guidelines!! I know the thread used is pretty darn heavy duty.

the thread holds together several (2 or 3) layers of fabric, increasing the available strength- much like stacking 2 2x4's into a 4x4- also consider that the load (pull) is cross ways to both the fabric and the direction of the stitches, which helps transfer the load into the fabric before any one stitch fails. Hope that helps, KM
