International Space Station has a Large Hadron Collider – and it’s collected 18 billion cosmic rays

The largest-ever experiment in space has reported the collection of some 18 billion “cosmic ray” events that may help unravel the Universe’s mysteries 알라딘 1992년 영화 다운로드.

Run from a centre at Cern, the Alpha Magnetic Spectrometer (AMS) aims to spot dark matter and exotic antimatter.

At the heart of the seven-tonne, $2bn machine is a giant, specially designed magnet which bends the paths of extraordinarily high-energy charged particles called cosmic rays onto a series of detectors, giving hints of what the particles are mms wmv.

A series of ever-larger particle accelerators built here on Earth aim to drive particles to ever-higher energies, smashing them into one another to simulate the same processes that create them elsewhere in the cosmos 축구 앱 다운로드.

But no Earth-bound experiment can match nature’s power as a particle accelerator – and Earth’s atmosphere absorbs incoming cosmic rays – so the AMS will catch some of these high-energy particles “from the source”, as a kind of complement to the likes of the Large Hadron Collider 다운로드.

What is the Higgs boson and why does it matter? (in simple terms)

What is the Higgs boson and why does it matter? (in simple terms)

If you remember basic chemistry, the atom is made up a proton, neutron, and electron. Those were the basic building blocks of life when I was a kid. I remember illustrations showing the neutron and proton in the center with the electron orbiting around it 둥지 짓는 드래곤 다운로드.

In the 1960’s several physicists starting thinking about things smaller than atoms, called sub-atomic. They developed several theories about these sub-atoms until the 1970s, when one model stood out. This is called the Standard Model of physics.

In that model, there are 12 particles and 4 forces. The particles are called quarks and leptons, and the forces are called – strong, weak, gravity, and electromagnetic 다운로드.

The forces are the most important because they describe some pretty amazing things. For example, the electromagnetic force is carried by a particle of light, called a photon. The photon has infinite range and great strength, giving the light of stars the ability to travel thousands of light years to be seen on Earth.

The force of gravity is carried by a particle called a graviton 초콜릿 영화 다운로드. It also has an infinite range but a very weak strength. For example, the Sun exerts a powerful pull on the Earth because it is very close, but when you get farther away that strength becomes minimal. It does not have the range that the photon does.

Both of these particles, and all of the particles that involve energy, are called bosons. These bosons are sub-atomic particles that transfer energy to each other 다운로드.

Now, the interesting thing is figuring out why these photons can travel for infinite ranges, when other particles can barely keep moving.

The leading theory, calls for a Higgs field that covers the entire universe. It is an energy field made up of a particle called the Higgs boson. When a particle travels through the universe it either attracts the Higgs boson or pushes it away 테드 영상 다운로드. If it attracts the Higgs boson then they combine to form matter and gain all the properties of mass (weight, gravity, etc.). If it repels the Higgs boson then it continues to travel as a form of energy over an infinite range (light).

The combination of the Higgs boson with other particles creates life as we know it, the matter that makes up humans, plants, rocks, etc. This is most likely the reason why it has come to be called the “God particle.”

The forces that ignore the Higgs boson do so at varying degrees 꿈이 아니길. Photons of light ignore it completely. Other particles attract some Higgs bosons and slow down, eventually limiting their range and strength.

Of course, none of this was certain because scientists were unable to see the Higgs boson. Being a sub-atomic particle it is invisible to the naked eye and undetectable in a lab. It puts us in a weird predicament, how do you find something that you are not even sure exists 다운로드?

CERN’s Large Hadron Collider solves that problem for us. This gigantic particle accelerator allows us to speed up particles and smash them together. Specifically, it smashes together hadrons which are multiple particles combined together.

When these particles are smashed together the scientists observe what happens 다운로드. If everything acts like the Higgs theory says it does (i.e. there is a Higgs field with Higgs bosons that slow some particles but not photons), then they have proof.

With that proof the scientists of the world can move on to other more complex problems. Areas where this model falls short like with dark energy or the full theory of gravitation 임협헬퍼 극장판 다운로드.

Another step in our greater understanding of the world. Each one allowing us to do more with energy, matter, and life.

Do galaxies form like snowflakes? Winner of Space Lab competition to find out

I'd love to be an Astrophysicist or specifically a Theoretical Cosmologist.

The Space Lab competition from YouTube invited young scientists to submit an experiment for the chance to have it performed by NASA aboard the International Space Station 다운로드.

From among thousands of entrants, six regional winners have been chosen. In North America, Emerald Bresnahan of Plainville, Massachusetts, was chosen for her Snowflakes in Space experiment realtek HD 오디오 관리자.

Emerald suggests that galaxies might form in a similar way to snowflakes. She wants to test how snowflakes form in the absence of gravity to better understand the link between them and other complex shapes like galaxies 다운로드. Will these tiny structures give us the answers to some of our biggest questions about the Universe?
