Summary

Perhaps one of the most common technologies seen in science fiction is anti-gravity and gravity manipulation. Today we'll examine if there's an scientific pathways in physics to permit such technology, and what sort of amazing options it might offer if developed in the future.

0:00.0	Hello, SFIA audio listeners, in this month's Nebula exclusive, Big Alien Theory,
0:05.2	we're asking the reason alien civilizations might be rare is because most aliens are huge.
0:10.5	To hear it and every episode early and add free, plus hours of bonus content,
0:15.1	check out go.nebola.tv slash Isaac Arthur and use my code, Isaac Arthur.
0:20.0	This episode is sponsored by CuriosityStream.
0:24.1	Gravity is the weakest of the fundamental forces in nature, but when it comes to climbing up
0:29.7	to humanity's future, it really draws us down.
0:33.1	The A few weeks back we did an episode on Clark Tech, hypothetical technologies so advanced they are indistinguishable from magic.
0:56.2	There we defined it as technologies that either at least had a basis in some plausible
1:00.7	scientific theory or were very conceptually straightforward like time travel, faster
1:06.2	and light communication or anti-gravity.
1:09.3	That was a survey episode covering many of these technologies quickly and we did a poll on
1:14.3	the SFIA community tab to see which one we'd look at in detail first, and anti-gravity
1:20.2	one hands down.
1:22.9	Fortunately it's a technology that requires very little, as both anti-gravity and artificial
1:28.6	gravity are staples of science fiction. And today we'll look at both some of the science
1:33.7	that might allow either version or a close approximation of them, as well as some less obvious
1:40.0	but powerful applications of gravity control like blowing up planets.
1:45.7	Gravity manipulation is an interesting one from a scientific perspective, because while we
1:50.3	really have little on the table to allow it, it's also a very poorly understood force,
1:55.9	which is ironic since it was the first of the four fundamental forces in nature we humans learned about,
2:02.0	even before Isaac Newton and his fabled apple falling on the head experience. Any projectile weapon,
