Any Scientific American Readers amoung us?

Very interesting article in September's Einstein issue about Dark Energy and scalar entities... anyone else a reader/subscriber?

pr0digal jenius · Oct 10, 2004, 02:07 AM

nope...used to be as i got it free through ym highschool...lol

but my college doesn't give me SA....MSDN...but no SA....lol

but yea, they have very itnerestign articles..i used to love reading it

i'm interested in that stuff... i know "of" those to subjects.. nothing much at all though.. just that i've heard of those 2 terms and a bit about them (although i might be getting them confused with other things)

Dark Mass being another possiblity

by dark mass i'm guessing you're referring to anti-matter judas?

actually Dark Matter, Anti-Matter are 2 completely different things...

Dark matter i believe (if i understood correctly) is a super heavy and highly gravitational form of matter... I think it's theorized to be on the verge of being a subspace form of energy that can effect things in normal space. As far as that i'm unsure of any more details.. or if i got what i know is even right...

Anti-matter is pretty self explanitory i think PJ

Dark Matter and Dark Energy i think are the same thing.... or somewhat related.... (would make sence)

lol...woops...yer right....i got confiseded...i knew 2 of em were close together....its late and im on my 5th dr. pepper....leave me alone

I am Jon, but I wont mention it on the bus...lol
sure I saw the articles....what are you up to mate?

Dark matter is what is postulated to account for at least 90% of the mass of the Universe, but which has not yet been directly detected. The evidence for its existence comes mainly from observations of what's going on with the behaviour of stars in galaxies and of galaxies in clusters of galaxies, from gravitational lensing and from cosmological models. Candidates for dark matter: brown dwarfs and black holes to weakly-interacting elementary particles such as low-mass, fast-moving neutrinos or massive, slow-moving cold dark matter particles.

Dark Energy is related but different... it is the thing that is believed to be causing the acceleration of the expansion of the universe. It is the residual energy in empty space. It is gravitationally repulsive. It is spread throughout the universe and appears to contribute to 70% of the energy density of the universe. It's existance was inferred by the happenings of a distant supernova and from combining CMBR anisotropy measurements with measurements of the density of dark matter. The cosmological constant is considered to be a particular form of Dark Energy and other candidates for Dark Energy include a very light scalar field. It is a large, negative pressure which may also help to explain the vacuum of space.

Anti-matter is matter composed from antiparticles... they are just like ordinary protons and electrons except they are oppositely charged (anti-protons, positrons)... when anti-matter and matter collide both are destroyed and other elementary particles are produced.... like photons. Particles with properties like these have been produced in particle accelerators.

can you imagine a game called DARK MATTER?

There's a game maker thing called Dark Matter... uses the Dark Basic coding language.

lol...dark basic....the frontpage of game making

Hey Tasty,

Haven't read it in a couple years, but do enjoy Scientific American a lot.

The most recent Discover magazine has a lot of interesting stuff on Einstein himself, with a lot of viewpoints on the theories he postulated...

Yeah, dark matter is basically matter that absorbs (rather than reflecting - which is how we observe things) most radiation, visible and otherwise, and thus escapes direct detection.

Oh, so Dark Energy (didn't know what that was...) could be considered anti-gravity? If so, imagine if we could harness it! There's your flying saucers, elevators to the moon...

well... sort of anti-gravity i guess... as for elevators to the moon... we only need to suss buckminster fulrene + carbon nanotubes to be able to do that
