aliens and astronomy -

Yeah, poor choice of words. But it was less awkward than 'over a very short distance' and I figured that it was close enough, given that time and distance tend to be referred to together when you're talking about light.

did anyone hear on the news yesterday that they found some particles going 10 nanoseconds faster than the speed of light?

Bullet Magnet · #**723** 09-24-2011, 02:04 PM

If they really did.

I think it's most likely to be a math error

Scientific announcement + Public media = Scientific "fact"

Bear in mind that the scientists themselves presented their results so that other people could look at it and find what they'd done wrong.

Do these particles have any mass?

VirturisticFire · #**728** 09-24-2011, 10:04 PM

My idea is that humans on planet earth are alive so there are probably aliens just not in our galaxy.

They have a miniscule mass and are electrically neutral.

moxco · #**730** 09-25-2011, 12:19 AM

It's not really my place to say, but I'm guessing they've made a mistake then.

Keep in mind Scraby lives in Croatia.

Croat media isn't that different from Serb media; their media can be quite fucking weird at times. But, occasionally right. As in... SERBIA BOMBZ TEH BOZNIAKZZZ

So... Croatian scientists may have discovered said particles.

STM · #**732** 09-25-2011, 01:14 AM

'discovered'.

It is physically impossible for anything with mass to exceed the speed of light. Unless maybe the scientists found something like an anti photon...travelling at the speed of light+1. Badass.

Dixanadu · #**733** 09-25-2011, 01:41 AM

Well, grow a beard and call me Sally...

SomeOddworld · #**734** 09-25-2011, 03:54 AM

It's debatable as to whether they're in OUR Solar System, but I believe aliens definetly exist somewhere in the Universe (perhaps they're quite close to us).

The point that those scientists were making was that if their experiments were accurate, all the physics models we currently teach are all wrong and would need to be revised. So... I don't really see what you were trying to say in your post.

STM · #**736** 09-25-2011, 05:54 AM

Well if that's the case then wouldn't that be fantastic! Something so revolutionary as to make how we perceive physics as redundant! Truly mind blowing, although it's more likely they made a mathematical error somewhere.

Bullet Magnet · #**737** 09-25-2011, 10:12 AM

And with that, STM has outlines exactly why scientists love discover that they're wrong.

Scraby · #**738** 09-25-2011, 10:15 AM

well i dont think they did a math error they did it a couple of times over and were stunned by the results,they mesured it aftherwards couple of times and it was stunning....

STM · #**739** 09-25-2011, 10:27 AM

For those of you interested, the particle is called a neutrino and by being a neutral particle it is not slowed down magnetically by other nor are they affected by electromagnetic forces acting on electrons. Rather only by weak sub-atomic forces. As such they can travel long distances very quickly before being stopped.

MeechMunchie · #**740** 09-25-2011, 10:35 AM

Well duh.

Bullet Magnet · #**741** 09-25-2011, 01:16 PM

They're also notoriously difficult to detect. For starters, they tend to pass through neutrino detectors unimpeded.

LDG519 · #**742** 09-27-2011, 02:09 AM

this is probably crazy nonesense but is it possable that the gravity of earth bent space in a way were the neutrino got to the detector earlier without actually going faster than light?

Scraby · #**743** 09-27-2011, 02:31 AM

the neutrino got quicker than light,so what its a breaktrough in science,we cant say that there arent things that are faster than light that would be a bit funny,just as people believed that nothing could go faster than the speed of sound,and today we have jets that do just that.

Or maybe they made a mistake in their experiment. Back in 1989, some physicists claimed to have produced cold fusion, but given that no-one has been able to reproduce their results since then, we haven't gone back and rewritten the physics textbooks.

I don't quite follow your logic, but I am quite sure that the experimenters would have taken that sort of thing in to account.

Scraby · #**745** 09-27-2011, 03:57 AM

well i dont believe you can make 5 times a mistake,they relaunched it a couple of times and the neutrinos were faster than light,you cant make mistakes that mutch,at the first time when they launched it they also thought it was impossible,then they rechecked all of the equipment and relaunched a couple of times till they saw that the neutrinos were faster.

also i have been reading that some scientists found dna on an meteorite that fell on earth recently

Wings of Fire · #**746** 09-27-2011, 04:28 AM

You can make a mistake 100% of the time if the way you perform the experiment is faulty to begin with.

shaman · #**747** 09-27-2011, 04:34 AM

Faster than light particles?

Talk about being relatively uncertain.

Nope. They found some chemicals that resemble the ones that are necessary for life to exist. It's not proof of anything, but the fact that we're made of chemicals that are possibly quite common in the universe. Which makes sense, after all.

STM · #**749** 09-27-2011, 09:34 AM

I think that as far as meteoric life goes, we have yet to find any extremophiles however, there are amino acids present on a lot of asteroids. Which is cool.

Scraby · #**750** 09-27-2011, 10:34 AM

try to translate this site with google or something,it says that actual dna is found on a meteorite http://www.znanost.com/clanak/pronad...u-meteoritima/
