One day I learned that the relative size of the nucleus of an atom to it's electrons is huge. There's a ton of empty space between the center and the electron cloud floating around it's outer edge. If an atom were the size of a stadium the nucleus would be a small marble in the center of it. If it were the size of the earth an electron would be less than 10 cm in size.
Now since we and everything around us are made up of atoms, if you were smaller than an electron you would pretty much be passing through empty space, all the time.
The next thing that kind of hits me after I start thinking about this is that matter is essentially compressed energy. Because of Einstein we know that E = mc^2. If you do some algebra you get m = E/c^2 or Mass = energy divided by the squared speed of light! So to me that means that matter is just energy or light slowed down by a factor of 186,000 miles per hour, squared or 34.6 billion times.
This might all be completely bogus but think about it a little, if God made light, then he could make solid stuff out of it.
So this gets me to the point that freaks me out. We're all just floating around on pretty much nothing. The only reason we don't fall through the floor or pass through objects is because everything around us is the same size as us and so we bump into it. We can open doors, walk on the ground, stay on the earth, touch people, all because of interacting electron clouds! We're basically floating around in and made up of solid light/energy/waves. Stuff that's slowed down enough to bump into other stuff.
If God hadn't congealed all this light we wouldn't have been able to interact with each other. We wouldn't be able to talk to anyone, or see anything, or move around.
The implications of this are amazing. We have been given the gift of a world that can be manipulated by the thoughts and actions we take for granted. With this matter around us that is basically nothing but clumps of light, we have an entire lifetime to use it for how God wants us to. There's no way we would exist without him, we too are made of nothing but this dust he formed. So what better way to thank him than honoring his will in being kind to one another, for we are here today and gone tomorrow.
