What is the memory capacity of a wireless device?
Is there a way to store and send information on a completely wireless system?

We're wondering....
How can a collection of atoms create thought (like in people)?
How do atoms move through time and space? For example, how do atoms in our bodies move to make us move?
If the universe is expanding and everything in the universe is getting further away from each other, are the individual atoms that make us moving further apart as well so that we'll eventually disconnect?
How do they keep the cloud cables dry if they're under the ocean?

Do atoms ever stop?
Is there a point when you're splitting atoms so much that they're not considered atoms anymore? If so, what would they be?
If there is nothingness beyond the universe, how could that be? How is nothingness possible? Could there be a place where there is nothing? And if there is nothing, how can we call that a place?
What is the likelihood of another element being discovered?

About the speed of light
The speed of light is very fast, as you know. It slows down a bit when it (i.e. the photons it's made of) bump into atoms in our air. Based on Einstein's work, we now think that the speed of light is the maximum speed that any object with or without mass can go.
Do you understand mass? You may know it as weight, but that is only on Earth. Mass exists everywhere! We use mass constantly to calculate important things to understand our world. When we push on something, our Force equals mass times the acceleration of the thing (F=ma). When something is moving, it has a certain momentum that keeps it moving based on its mass and velocity (momentum = mass x velocity). So we use mass all the time. In gravity like here on Earth, mass is the same as weight. Two objects with mass attract each other with gravity. Our planet has a lot of mass so it attracts all of us and gives us weight. All of the things that we live with, like cars and airplanes, travel at far less than the speed of light because of their mass.
We don't understand why the speed of light is the fastest speed that anything can go. We may learn that as we learn more about physics. It has something to do with how our world is built, but we don't fully understand it yet. If you learn as much as you can about physics, then maybe you can help us understand more about our world!
