Muscle soreness or discomfort that occurs 24 to 48 hours after exercise is normal, particularly if the exercise involved a high amount of eccentric work (e.g., downhill running, resistance training, landing after jumping) or activities you are unaccustomed to performing. There are, however, occasions when the pain or discomfort can mean that something more serious is going on. If you have any of the following symptoms you shouldn’t exercise until it improves or you are cleared for exercise by a medical professional. 
No pain, no gain No pain, no pain!

Scale of the universe

Scroll to your hearts content from the Planck length to the diameter of the observable universe - click on any object and it will open an info box - I can’t imagine how much work must have gone into this. A few surprising things: Pluto has a smaller diameter than the width of the USA and Vatican city can fit in central park multiple times.
