All they need to do is turn into wheels with arms. Then they can do what they wantIf they could in some way manipulate their crystalline growth, they could perhaps fashion themselves into simple machines, which could in turn produce more complex machines.
Wheels or they could phase shift in and out of dimensions if they need to travel. Their ships operate in a similar way maybe, that is how they get around? They found that shifting dimensions was not limited to their habitatI like the way you think. And I love finding common ground
Whether or not sentient beings in, for example, crystalline form could become mobile or not, now that's a good question!
Win and they would have very fast Internet, even from the first days of the Internet in their technological historyYou could, for example, imagine a race of intelligent crystalline structures which function like advanced quantum computers. They could trap light inside their forms, bouncing it around inside themselves to alter the quantum states of their individual particles to achieve sentience. Such immobile life forms would not use technology of any kind, since they cannot manipulate the world around them, but they could very well exist in a virtual society. They could even be mobile in some mechanical way. Such life could exist on a planet almost regardless of the gravitational conditions.
Keep dreaming, its fun!So, not to worry, I'm not saying you've got your facts wrong, I'm just "dreaming" if you like
