MOND: Trying to Solve the Problem of the Missing Universe

One of the greatest mysteries of astronomy is the problem of the missing universe. Well, the universe isn’t exactly missing, but a lot of its mass is. Ultimately, all of the matter scientists can see in the universe accounts for only a small percent of the observed gravity. Everything on Earth, everything we’ve ever observed with our instruments, all normal matter—it all adds up to less than 5% of the Universe. Essentially, some unobservable something in influencing the motions of the cosmos.

Astronomers often use dark matter to explain this missing matter. However, the dark matter interactions that scientists believe they observed remain inconclusive. Thus, scientists have yet to definitively determine that dark matter exists. In fact, we may never actually be able to detect it... and it isn"t ideal at predicting all manner of situations. As you see, dark matter does have some problems.

Some researchers think that the problem is really our understanding of gravity. In order to explain why the universe seems to behave as if there"s so much more matter in it, some scientists advocate MOND (Modified Theory of Newtonian Dynamics) instead of dark matter.
