Calling E.T.

Tonight as I was out walking I shined my flashlight at Jupiter. It's a really nice flashlight -- very bright -- and a cool planet -- also quite bright in our sky. So I started wondering how long it will take for my meager photons to get to Jupiter. At this website I discovered that Jupiter is currently 4.545 AU from us, or 679,922,910 kilometers. That means, if my Google-math is correct that my light will get to Jupiter in about 38 minutes. Well, will have gotten, then. I've been home about an hour.

PS. Google-math is doing multiplication, addition, units conversion and the like by typing them into the search box on Google. For those of us who are too lazy to click the start menu and launch the calculator program.

PPS. My flashlight is da bomb.

Taking Care of our Bodies

Something I've heard before:

"One of the purposes of this life is to learn how to take care of our bodies."

Think of your conception of what heaven will be like. Do you eat or not eat? (Can you?) Can you get hurt or not get hurt? Does your hair grow or not grow? Do you need to sleep or not? Poop? Etc.

Now, tell me if the above sentence makes sense together with your conception of heaven. Why or why not?
