The Mystery Of The Oh My God Particle | Answers With Joe



On October 15th 1991, astronomers recorded a cosmic ray that was moving faster than should be possible – and despite the fact they’ve found a whole lot since, they have no idea where they come from.

From 1983 to 1991 on the Dugway Proving Ground in Utah, an experiment had been under way by the University of Utah called the Fly’s Eye Cosmic Ray Detector.

And this is how they found the Oh My God particle, but before I explain it, let me back up and talk about cosmic rays so you can fully grasp the Oh My God reaction here.

Cosmic rays are mostly made up of the nuclei of atoms, 90% of them are single protons – the nuclei of hydrogen atoms. These are much higher energy than solar radiation because unlike photons they actually have mass.

This was the first ultra-high energy cosmic ray discovered, which was shocking not just because of it had a lot of energy, but because it kind-of shouldn’t have been possible thanks to something called the GZK cutoff.

GZK stands for the scientists Kenneth Greisen, Georgie Zatsepin and Vadim Kuzmin, who set a speed limit for cosmic rays at 5 x 10 to the 19th electron volts, or 8 joules of energy. It was believed that particles couldn’t exceed this limit due to interactions with photons in the microwave background radiation.

This new class of cosmic rays became known as trans-GZK cosmic rays. They are super rare and believed to be from fairly close by in order to have that kind of speed – the less they’ve travelled, the less they would be slowed down by the CMB.

Since discovering the OMG particle, there have been a slew of new cosmic ray observatories like the Pierre Auger observatory and the Telescope Array Project, which is the successor to the fly’s eye.

There have also been efforts to focus on high-energy neutrinos with the belief that they may be created in a similar process to the high-energy cosmic rays. There’s an observatory underneath the south pole that specializes in that.

    What if antimatter is still in our universe? What if all the massive voids that we see in between all the superclusters are where matter and antimatter annihilated each other? If any antimatter never came in contact with matter, it would still be there. What if what we see in the Observable Universe are clusters of antimatter just isolated from the clusters of regular matter? If you could make a video about what you think on that, that would great.

This Is The BIGGEST Discovery Found By Accident…




This Is The BIGGEST Mystery Found By Accident…


It’s kind of amazing that we’re sitting here in the year 2018, yet new discoveries about the planet still manage to surface every day. Some include newly undiscovered places or animals that no one has ever seen or documented before. And that is exactly what we’re talking about here today on Top 5 Supreme.

Before we get started with today’s video don’t forget to click the bell to get notified every single day with the best Top’s you’ll ever see. Also, don’t forget to subscribe to this channel. So let’s get rolling!

#5 Large Skull

Imagine having your own farm and one day discovering that your land is the exactly location where an ancient animal lost his life? That’s exactly what happened to this soy bean farmer in Michigan. James Bristle made this crazy discovery recently. One day he saw something sticking out of the ground. On first thought, he imagine it was probably some time of fence post. But, it wasn’t. After getting a team to dig deeper into the land he found out that his land was the proud owner of an ancient wooly mammoth skull that was completely intact! This animal lived here 15000 years ago. Wow.

#4 Potato Chips

So, how many of you love to eat potato chips? I expect to see everyone’s hand raised right now, by the way. Anyway who knew that potato ships were actually an accidental creation? In 1853 a chef in New York accidentally created the tasty treat when an annoying customer kept sending back his French fries because they were too soggy. So the chef, in an attempt to be funny, sliced his next batch of potatoes extra thin and drowned them in salt. To the chefs surprise though, the customer actually loved the new creation. And thus, potato chips were born! Pretty cool huh? Actually, I’m pretty hungry and could go for some chips right now. Oh, never mind. Moving on.

#3 Weird Wishes

Around 50 years ago a farmer in china wanted to build a new well on his land. So, he sat out with the proper tools and began digging into the ground. However instead of finding water, he found something pretty crazy, and kinda cool. What he found was over 80,000 – yes, I said 80,000 – perfectly preserved statues of ancient generals and warriors. It turned out to be the burial sight of an ancient general, and the fact that all of these were found relatively unharmed is a sign that he was a general of great distinction and respect. One more cool fact is that the general was only 13 years old when he ordered the construction of the statue army. 13!

#2 Voynich Manuscript

The Voynich Manuscript is one of the most bizarre discoveries ever made. The codex, or book, is written in some kind of alien code that not one person has been able to decipher. Found in 1912, it was discovered that the book was actually written in the 15th century. The contents of the book are pretty crazy – otherworldly animals, alien coding and nude women doing all sorts of crazy stuff can be found throughout it. The book is so unusual that the language that was used to fill the book is still yet to be deciphered. The scientists and researchers who’ve studied the writings within are all stumped to this day, leading some to believe that the entire thing is just a hoax. But, for what purpose? Others believe it was dropped here, a long, long time ago, by some kind of alien beings. Whatever it is, here’s to hoping that the writings are deciphered sooner than later.

#1 $2M Penny

How much are the pennies in your pocket worth? Probably just 1 cent. Like normal. But what if I told you about a penny that was actually worth about $2 million? Check this out. Robert Lawrence was the son of a guy that worked in the US mint. After his father passed Robert took over his coin collection that was just sitting in a little sandwich bag. One of the pennies in the bag – an all aluminum penny that was only 1 of 10 ever made – was originally believed to be worth about $300. But after a little more research it was actually discovered that it was worth $2M. That’s crazy!
