How to build a dark matter detector - Jenna Saffin

Rating: 4.0; Vote: 1
More than 2 kilometers below the surface of northern Ontario, suspended in 345, 000 liters of ultra-pure water, theres a perfect sphere. Scientists continuously monitor this chamber, looking for a glimmer of light in the darkness. Why? Because that light would indicate the presence of one of the universes greatest mysteries: dark matter. Jenna Saffin describes how this dark matter detector works. Lesson by Jenna Saffin

So what you're telling me is that people are using billions of dollars to try and detect something they know they probably wont detect? instead of using all that mula to help people live life and stuff? No wonder we're 233 billion in debt to people who don't exist.

This also could also be a very expensive experiment to detect something that doesn't exist. Don't get me wrong, experiments like this are important. What if, Dark matter, is interdimensional, and this expensive equipment is looking for the wrong thing.

1: 20 We actually dont know if dark matter is matter. As Neil DeGrasse Tyson says, we should actually be calling it dark gravity because dark matter implies that it is matter which we dont know that it is
reply

But. if it's matter, how can it reach a place radiation can't? It's like they have a thick lead wall and they're expecting a car to go through more easily than an atomic blast
reply

This sounds similar to an underground sensor setup to detect neutrinos. I sometimes wonder if dark matter has some neutrinos in it. Hopefully we'll find out sometime. soon?
reply

For me our understanding of physics is incomplete, and until there's a groundbreaking discovery which finds that puzzle piece, we won't be detecting dark matter anytime soon
reply

what I'd like to know is why they've chosen Ontario as a location for testing instead of any other random place (or multiple places for that matter) on Earth.
reply

Since we predict that we live on the surface of a 4d object, I think that dark matter is that gravity from the other side of the universe

Everyone say that they are falling into the pit of endless ellen videos but Iam falling into the pit of endless science videos.
