Things that make you go "hmmmmmmm..."

Amazing stuff but I thought that I read an article on here claiming that someone had discovered evidence of dark matter. It was a long read so I didn't pursue it. Anyway if this is true it would indeed turn some of hard physics on its ear.

I don't believe in gravity.

What is the opposite of gravity?....

Bekenstein’s theory has three functions which characterize space-time—a tensor, vector and scalar (TeVeS)Ha, I knew it.

An attractive theory, to be sure. However, it needs more research before the weight of evidence will sway more people. Still, it could pull in a lot of funding as scientists weigh the relative merits vis a vis the standard theory.

On 14-Dec-2006 by Abe "...we are asking the community to believe in the existence of a particle that has never been seen. We have to be damned sure that you can't explain the universe without this huge leap." Because seeing is believing? Why is it so difficult to believe something you can't see? To limit the universe to what you can see is damned arrogant I think!
What's "damned arrogant" is pretending they know something when they don't.

Until they observe dark matter, I'm pretty skeptical. Thanks for posting this article.

Dark matter has been observed, but gravitation results from energy density. The vacuum is one source. The recent discovery of axions show one source of dark matter. Axions are particles with a small mass(10-6 10-3 eV) that provide for the observed CP invariance in strong interactions in the Std Model.

Hey, everybody believes in force. Nobody's ever seen force. That doesn't mean that force doesn't exist.

Good, it was starting to get crowded in here with all that "dark matter" floating around!

I was discussing gravity with my son a few years ago and he brought up the fact that it is just a Theory of Gravity. This article is very interesting. I said well I guess the earth's spinning holds us on? He said Like an electric fan with blades spinning? That throws things OFF.

I do notice that gravity is weighing me down more and more now that I am elderly! It makes me weigh too much.
