A collider is a type of particle accelerator involving directed beams of particles. Colliders may either be ring accelerators or linear accelerators, and may collide a single beam of particles against a stationary target or two beams head-on.
Colliders are used as a research tool in particle physics by accelerating particles to very high kinetic energy and letting them impact other particles. Analysis of the byproducts of these collisions gives scientists good evidence of the structure of the subatomic world and the laws of nature governing it. These may become apparent only at high energies and for tiny periods of time, and therefore may be hard or impossible to study in other ways.
In particle physics one gains knowledge about elementary particles by accelerating particles to very high kinetic energy and letting them impact on other particles. For sufficiently high energy, a reaction happens that transforms the particles into other particles. Detecting these products gives insight into the physics involved.
Chris Hemsworth (born 11 August 1983) is an Australian actor. He is best known for his roles as Kim Hyde in the Australian TV series Home and Away (2004) and as Thor in the Marvel Cinematic Universe films Thor (2011), The Avengers (2012), Thor: The Dark World (2013) and Avengers: Age of Ultron (2015). He has also appeared in the science fiction action film Star Trek (2009), the thriller adventure A Perfect Getaway (2009), the horror comedy The Cabin in the Woods (2012), the dark fantasy action film Snow White and the Huntsman (2012), the war film Red Dawn (2012) and the biographical sports drama film Rush (2013).
Also in 2015, Hemsworth starred in the action thriller film Blackhat, had a comedic role in the fifth installment of National Lampoon's Vacation series, Vacation, and headlined the biographical thriller film In the Heart of the Sea.
Hemsworth was born in Melbourne, to Leonie, an English teacher, and Craig Hemsworth, a social-services counsellor. He was raised both in Melbourne and in the Australian Outback in Bulman, Northern Territory. He has stated, "My earliest memories were on the cattle stations up in the Outback, and then we moved back to Melbourne and then back out there and then back again. Certainly most of my childhood was in Melbourne but probably my most vivid memories were up there in Bulman with crocodiles and buffalo. Very different walks of life." He attended high school at Heathmont College before his family again returned to the Northern Territory, and then moved a few years later to Phillip Island. He is the middle of three boys; his brothers Luke (older) and Liam (younger) are also actors.
We've lost our heading
We have lost our way
Now fear is spreading
We fall and pray
We're getting closer
To the end
Head spinning faster, faster
When our worlds collide
There is nowhere for us to hide
Yeah we live and die
On this universal time
No more debating
Much to our dismay
The world is fading
Into decay
We're getting closer
To the end
It's spinning faster, faster
When our worlds collide
There is nowhere for us to hide
Yeah we live and die
On this universal time
We're treading water, we're getting further,
We're heading undone, upsetting all out [?]
When our worlds collide
There is nowhere for us to hide
Yeah we live and die
On this universal time
