And even further to that, IceCube can give us a unique view into the heart of these phenomena.

Because again, unlike photons, neutrinos can escape relatively unscathed from high energy environments such as the core collapse of supernova explosions.
voice-verified
or cataclysmic mergers of unfathomably dense neutron stars, or even the searing fury of supermassive black holes, IceCube can deliver new and different information.
voice-verified
It can see things light-based telescopes are blind to, so to speak.
voice-verified
The neutrinos it detects can hugely broaden our understanding of all these events, and of the most fundamental nature of the universe.
voice-verified
During these events, physics is pushed to its limits.
voice-verified
Particles are accelerated to speeds and energies thousands of times greater than what we can achieve in our particle accelerators on Earth, like that of CERN.
voice-verified
This allows physicists to test their theories.

and use the arrival of neutrinos at IceCube to make new discoveries, not only about the behaviour and properties of neutrinos, but also about dark matter and even about ice itself.
voice-verified
This is why so much effort was put into building such an extreme telescope as the IceCube Neutrino Observatory, an effort that took seven years to complete, with work pausing during the Antarctic winter when planes are shut out from Earth's most southerly continent by the brutal weather, only able to briefly resume for the summer months of November to February.
voice-verified
Over those 7 years, the IceCube team drilled 86 holes 2.5km deep using 18,000 litres of fuel per pole and melting 750,000 litres of ice in the process.
voice-verified
All to have a few hundred scientists live and work in one of the most inhospitable environments on our planet in an attempt to understand the most extreme events in our universe, and to capture a glimpse of the most elusive particle in the universe.
voice-verified
Neutrinos are the phantoms of the particle kingdom.
voice-verified
It takes bold and ingenious ideas from ambitious scientists to witness even a single one neutrino.
voice-verified
We know so little about them compared to other particles, but they are just as important in furthering our understanding of the fundamental laws of nature.
voice-verified
With each neutrino detected, we are moving closer to comprehending the universe and the powerful forces that shaped it.
voice-verified
Light is so much stranger than you might think.
voice-verified
Sure, it may seem simple enough, travelling around the universe, delivering energy from one place to another.
voice-verified
It helps us see, it provides life to plants, and thus to our planet generally.
voice-verified
It has a reputation for being very fast.
