Not everyone is made equally when it comes to baseball. Some people are pretty good at it, and some people (like me) are shockingly bad. And then there are people like Luis Arraez of the Minnesota Twins, who displayed such control of the ball in their game against the White Sox that he hit an incredible curveball, earning his team a home run. It's not magic that made this possible, it's physics.
These obviously aren't actual photos of the 'ghost particle', but its amazing how creative some publishers will get, when trying to illustrate how some sort of particle on the nano-spectrum looks. Ever since the first detection of neutrons in 1970, scientists have been doing whatever they can to try to learn about, and isolate the particle. But how does one go about identifying the mass of an object that is one of the closest to having no mass? The brightest scientific minds have been working for decades to figure it out. But for now, what we know is simply the upper limit that the mass of these particles could reach. The lower limit could literally be nothing, so there is still a lot of work to do.
Scientists are saying the discovery begins a new era of space science and research. Maybe one day we'll finally get a selfie with an alien. For now all we can do is wait for the next raid of Area 51 to check out what is really out there beyond out planet.
