Is it true you have 3 quarks that make up a proton...but one quark is bigger than a proton? How come? Can it be said that a quark is the smallest size that a sub-atomic particle can ever be broken down to? :smile:

I thought the universe starlight condensed to a point... Like what Abdul Ahad's constant was saying:) http://siliconvirtue.com/read.php?f=141&i=839&t=826 and bottom of this page:) http://www.astroscience.org/abdul-ahad/aa-glossary.htm E

nice dream It's cool for a sci-fi thing, but the above poster is right: we're still a long way off from this. So when is your novel due out/ who's publishing it? E

I hope we never hsve to use it... on our fellow mankind (pacifist!) Eridanus1

I saw this binary with me friend's 10-inch. The secondary looked so blue I could not believe my eyes! Has anyone hear noticed the deep colour of this lovely double star? Eridanus1

I really hate to sound pessimistic, but we have never achieved even 1% of light speed in any spaceflight, let alone hope to go FTL with anything imaginable in the current era. Yes, we all like to dream of warp engines and the like, and so we should, but I think many physicists are simply...

What is the biggest explosive potential of a nuclear weapon? Is it a deuterium-tritium based chain reaction or something more advanced than that? If the film 'Independence Day' became real, what could we use to zap the alien ships? What is the ultimate destructive weapons at our disposal in...

What is the highest tensile strength material known to man? can we use for builsing a spaceship or o neil habitat? I think it has to be titanium based, but what is it. Is it possible to alloy titanium with something exotic like ---- e.g uranium? No?

they are the oldest things in the galactic halo, having formed near the birth of the milky way. So with all the 10 odd billions of years of existence, i think they all should have gone supernova and destroyed the shape of the cluster. So how do they stay gloubular in their shape?

Sooner or later its bound to happen. Has there been a recent observed colliding force between two stars in our Galaxy? i'm keen to see a collision between a red star and a blue one to know what colour the end star will be. E

Cosmology is a difficult subject, so much opinions and room for errors. The distances and timescales are quite dizzying, to say the least. But that don't mean we should stop trying to gain more answers, eh? :-) What is the latest, most accurate value of the 'Hubble cosntant'? Is there a...

Not all romantic. Scientifically alpha centuri A and B can hold life bearing planets, proved here --- "In a binary system, a planet must not be located too far away from its "home" star or its orbit will be unstable. If that distance exceeds about one fifth of the closest approach of the...

Abdul Ahad wrote: "A Tiny Ray of Hope in the Eternal Darkness... Successfully locating an Earth-like planet in the habitable zone around one of the two principal 'suns' of the Alpha Centauri system will surely rank as one of the greatest discoveries in the entire history of science. Such...

Brightest gamma ray burst within milky way Let's hope there isn't a invisible magnetic neutron star circling a nearby star within 10 l/y... otherwise could be in big trouble: http://www.spaceflightnow.com/news/n0502/19grb/ Is there anything to rule out an unseen neutron star drifting the...

Ahha! My nephew beat you to it. He was just 8 when he drew up his first virtual propulsion bridge to alpha centauri... "Although a few sci-fi authors had previously written one or two fantasy novels that may have used the odd ice ball here or there as a means for propelling space vehicles in...
