It Took 100 Years, but We May Finally Have ‘Seen’ Dark Matter 

A NASA telescope may have detected evidence of dark matter , enabling it to be “‘seen” for the first time.

Since dark matter was conceptualized nearly 100 years ago by Swiss astronomer Fritz Zwicky, the invisible substance theorized to hold galaxies together that is supposedly all around us has largely remained a mystery.

Dark matter does not absorb, reflect or emit light, making it hard to observe directly and understand what it truly is. One theory suggests that they are "WIMPS", "Weakly Interacting Massive Particles", which are heavier than protons but, as the name implies, interact very little with other forms of matter.

Despite their shy nature, when two WIMPS collide they are predicted to annihilate, releasing other particles—including gamma ray photons—as they do so.
