Forums - General - Antimatter atom trapped for first time

Wow this is interesting. I didn't even know anti matter existed. Now I'm off to read up some more about it.

Very cool, I was actually wondering a while back if any progress was being made in this direction since antiparticles are so easily made these days...

I like the whole LHC thing. You have to like a machine that looks like that. 

But... I'm not a professor , nor a super smart scientist , so , what is the use of crashing these atoms into each other ? Yeah , to find out more about our universe wen it was very young. But aren't there more useful things to put those billions of dollars in ? Like finding something as an alternative to oil , medical development , space exploration ? 

You'd be surprised how these answers can be important.

Things like the theory of general relativity probably didn't seem of much practical use at the time but is now an essential part of things space-related, such as the GPS system. Quantum also probably seemed a impractical, but it has profound implications for the future of energy which will probably be powered by fusion.

An understanding of the universe eventually seems to pay off in practical terms.

 

Also I think knowledge for the sake of knowledge is good enough =P.



Ok, now if we can only make a fully capable warp engine in my lifetime!  

Very cool read, without this kind of research we will never be able to provide enough energy to such things.

Well as we've mentioned in the thread, the formation of anti-matter atoms is allowing them to be studied for the first time, and antimatter may hold potential for producing massive amounts energy. So that's something practical.

But, as always, we wont understand the full applications of what we discover until we've discovered it (although we can hypothesise).

An analogy would be Einstein's theory of general relativity. When Einstein developed it nearly 100 years ago it had no foreseeable practical applications, but since then we have used that knowledge to develop many practical things like satellites. What seemed like a theory with few practical applications theory now underpins modern society.

There's a quote that fits well here, but I can't remember who said it right now. It's something like "I can't think of anything more useless than the invisible light that has been discovered".

By invisible light he meant the non-visible part of the electromagnetic spectrum which is now responsible for things like television, radios, x-rays machines, microwave ovens, space telescopes, etc. It seemed useless at the time, but it turned out to be one of the most important discoveries of all time.

Well said.

Plus, by trying to achieve big scientific goals, even the most distant from what you commonly think as everyday's life, we often give birth to useful technologies as a side effect.

Trying to detect gravitational waves led to build big apparati, and in turn to develop new dampening engineering techniques and peculiar materials that will be used in precision machinery all over the world.

Statistical analysis of biological and astronomical data was the reason for the development of much of today's parallelized computation techniques.

And obviously as the most self-evident example, let's not forget that HTML webpages were born at CERN, originally as a way for physicists to exchange hypertextual documents.

I see what you did there. :)

That's a good point too. In fact, I bet the engineering and construction knowledge gained from building the LHC at CERN is incredible. It is possible the biggest engineering accomplishment to date.

For those that don't get it.

I remember a discovery a year or two back where they thought they discovered some naturally hidden on earth.

Thats impossible.

When matter and antimatter interact, they destroy each other and release energy.  Antimatter does not exist on Earth, the Solar System, or the Milky Way Galaxy, as there is positive matter everywhere, even in the vacuum of space, that would destroy it.  Its possible that there are antimatter galaxies out there, but likewise they would have no positive matter in them.  However, I highly doubt there are antimattter galaxies because we see galaxies colliding throughout the entire universe and they all display the behavior of positive matter (or atleast the same type of matter).  If a positive matter and antimatter galaxy collided, it would be a sight to see...

The only way antimatter can exist here is through human creation and an artificial method of keeping it seperate from positive matter, such as a magnetic field.  We can then study antimatter for its physical properties or use it for energy storage (to be used in an engine, weapon, what have you).
