The reason entropy is a “force” that dooms things is that once maximum entropy is achieved, there is no energy differential, and with no energy differential you can’t perform any work, life cannot exist, electricity cannot be generated, etc.
The idea that entropy unstoppably increases predicts that, eventually, all energy will be “spent” and no life can exist - a timer for all sentience in the universe.
Also, launching probes into space doesn’t increase entropy (to be precise, the act of launching probes uses energy with some inefficiency, so it does increase entropy, just not through the fact that a probe is now in space), because pulling matter away from other matter increases potential gravitational energy. Maximum entropy in this sense would be all matter in the universe clumped together into an inert, uniformly mixed… Clump?
Also, I’m not a physicist, so I probably got some things wrong, especially terminology, so take this with a grain of salt.
