13 things that just don’t make any sense

There are mysteries in this world that still confound us.

1 The placebo effect

You induce pain in someone several times a day, for several days. You control the pain with morphine until the final day of the experiment, when you replace the morphine with saline solution. Guess what? The saline takes the pain away.  But, don’t try this at home.

How Galaxies Came to Be: Astronomers Explain Hubble Sequence

A figure illustrating the Hubble sequence.

For the first time, two astronomers have explained the diversity of galaxy shapes seen in the universe. The scientists, Dr Andrew Benson of the California Institute of Technology (Caltech) and Dr Nick Devereux of Embry-Riddle University in Arizona, tracked the evolution of galaxies over thirteen billion years from the early Universe to the present day.

The Milky Way Doomed to be Destroyed by Galactic Bombardment? Probably Not, Study Says

This image from a supercomputer simulation shows the density of dark matter in our Milky Way galaxy which is known to contain an ancient thin disk of stars.

As scientists attempt to learn more about how galaxies evolve, an open question has been whether collisions with our dwarf galactic neighbors will one day tear apart the disk of the Milky Way.

Physicists Search For Dark Matter

Milky Way Galaxy

95%. That is the percentage of the known Universe that is missing. As in it is not there. Or at least if it is there, we can’t see it. We call this unseen stuff “dark matter”. That has been well known for sometime. What is trickier in answering is why? Why is it that 95% of the universe is made up of this so-named “dark matter?” An even trickier question is where? As in where is this dark matter? It is those two questions that have plagued physicists for decades. Dark matter, by its own definition cannot be seen, hence its name. So how do we “see” it, how do we know “where” to look?

The Mysterious Mima Mounds

The Mysterious Mima Mounds 

We don’t know what they are, where they came from, or what caused them

Scientists love a mystery. Biologists used to have the human genome, but now they have the structure of protein. Physics used to have cosmic rays, but now they have the God particle. Astronomers used to have black holes, but now they have dark matter. (Pics)

Darkest Secret of the Universe Only Parsecs Away

Misbehaving Matter 

THE universe’s darkest secret may be hiding not far from us. Three dwarf galaxies near the Milky Way appear to contain a higher proportion of invisible dark matter than any stellar system so far studied. If so, they are the ideal place to look to figure out what the stuff consists of.

Dark Matter Still Confuses Scientists

The universe is expanding at an ever-increasing rate.

After a decade of research, scientists have come to this conclusion about dark energy: they still have no idea what it is!

Here’s a fascinating article on the most mysterious force in the Universe, the dark energy, by Dennis Overbye for the New York Times (no physics equations, we promise!):
