When was the last time you didn’t have any “strings attached?”
Lots of interesting stuff in that post.
Yes heating air makes it less dense, so it rises, but in rising it expands, and thus cools.
So what we find as we go up in the air is that it gets cooler (hence snow stays on the mountain tops longer than on the lower slopes, as it is cooler up there). This is known as the adiabatic lapse rate, and is about 2 deg C (3 deg F) for every 1,000 ft of altitude. So if it was 106 F at your ground level, then hopping in the balloon, and going up 5,000 ft, would make it a much cooler 91 (still very comfortable), going up a further 10,000ft would drop it to a cool 61, and a further 10,000ft would put you in the freezing zone.
In terms of being untethered, that is an interesting concept.
A tether to me is a rope that binds us to a stick in the ground.
We cannot escape the laws of physics, and sometimes we can organise within them to gain freedoms that are not normally available (like flying suspended beneath a balloon).
I do not see myself as tethered by anything, and I do acknowledge all of the many layers of laws and relationships and connections that exist, and within which I am able to exercise my freedom. I do not see those things as tethers, as in any sense restricting my freedom, quite the contrary, for without those laws and connections, my existence itself would not be possible.
It seems to me that our existence as aware entities capable of choice comes from the very small gap that seems to exist in the laws of nature, the small space in the probability curves that seem to define the laws that make matter and life possible. Within the boundaries of those probability curves we can exercise our freedom. When you multiply out that effect through enough levels, the freedom delivered is almost infinite.
So in that sense, my entire existence is untethered, but not unconnected.
