What's the matter with matter? (Strange Universe Series -- 2011).
We think the Universe must be made up largely of dark matter, a slow, cold form of as-yet-unknown particle which provides the gravitational glue needed to hold stars together and cause galaxies to accrete from clouds of particles, atoms and dust over time. But new research only deepens the mystery of it’s properties. Dwarf glalxies in our local neighborhood don’t show the gravitational distribution we would expect if dark matter exists as predicted.
After reading the linked article, what do you think about Dark Matter? Why is it so determined to keep is in the dark about its whereabouts? Do you think the entire model of gravity is fatally flawed, and Dark Matter is just a fudge-factor meant to cover the flaw, or that dark matter does exist and eventually we will find and understand it?
Here are the previous questions in the Strange Universe Series – 2011 questions. Here are the previous Strange Universe Series—2011 questions:
1—How do you envision space in more than 3 dimensions, then rotate it to see what happens?
2—How can we be certain the Uncertainty Principle is certain?
3—If the universe is infinite, how big is what it is expanding into?
4—In an expanding universe, how do separate galaxies manage to collide?
5—Since space is expanding and is linked to time, isn’t time expanding as well?
6—How can space expand between individual hydrogen atoms?
7 of False? When you’ve seen one entropy, you’ve seen them all.
