CERN: Light Speed May Have Been Exceeded By Subatomic Particle


            In this article it is said that Einstein's theory of relativity may have been disproved. The theory says that nothing can go faster than the speed of light or better known as E=MC2(squared). This theory has always worked until European researchers clocked a neutrino going 186,282 m/s. (cosmic speed limit) A neutrino is a subatomic particle, odd silvers of an atom  with almost no mass that have three different "flavors" and it may have it's own anti particle and shifts one flavor to anther while shooting out from the sun. The neutrino traveled 60 nanoseconds faster than the speed of light . The margin of error is only 10 n/s.  The scientist at CERN have spent months rechecking their findings. They still aren't ready to call it a new discovery. They want other physicist to try and verify their discovery. There are only two other labs that can replicate the CERN one. How could this happen?There could be shortcuts through other dimensions. Or the universe is not perfectly symmetrical like Einstein said it was. Although our life's will not change if this is a new discovery, will change our understanding of how the universe operates. This can be a revolutionary discovery.
         I think it is crazy how for so many years we have lived by Einstein's theory and all of a sudden it may not be correct. It's kinda like when people thought the world was flat. However I am glad that, there is new discoveries. The discoveries will only make the world better because we will understand everything a lot better and know how to go upon certain situations.

The mystery jar

 Mystery Jar

We have made a mystery jar but had to hand it over to anther group, but in return we receive a .... 

We get a mystery jar handed over to us. What is in it? How many different stuff is in there? How much of everything is in there? Will it explode?

When the mystery jar is handed over to us,  we first begin to observe what may and may not be what's inside. We observe that there may be iron in this mixture, therefore we grab a magnet and test it. The magnet test proved that there was iron. However the real question was, how much? Therefore we weigh the whole mixture(12.20 grams) But  now we had to figure out what else was in there. And by our observation we concluded it was sugar and Callisumcarbonate. To measure the Callisumcarbonate we used the wire mesh To separate the Callisumcarbonate from the sugar nd iron. Then we used the scale to measure it which came out to be 8.82 grams now to separate the iron from the sugar... We decided the best way would be to filter out the sugar from the iron. This would be done by taking a beaker and set the filter in, and add water to the compound of sugar and iron then dump it the filter. And wait for the compound to separate. Before picking up the iron with the magnet, we measured the magnet which was 5.66 grams and after, with the iron it weighed 14.17 grams.  So now its all simple math. 14.17-5.66=8.51
iron=8.51 grams
12.20-8.51=3.09 
So sugar = 3.09 grams 

Now to see how close the calculations were..... 
    Callisumcarbonate= 8.84 g
    Iron= 4.51 g
    Sugar= 3.11 g 

All our measurements were close except for iron, maybe the magnet threw us off. 

Now we know what is in the mystery jar!=]
    (and it did not explode) 

Chromatography lab

Chromatography lab

What we used: filter paper, markers, water, paper, tray

What will happen to the drawing on the filter paper if we set the filter paper on top of a tray of water with filter?

If we make a drawing on a piece of filter paper with markers  and set it on top of a tray of water with filters then the Inc will smutch.

To begin with we drew with markers on the filter paper. Then we poked holes in the filter paper and twisted some paper and set it in the hole or holes. (this served, kinda like a wick in a candle, as a filter) after that we set the drawing in the tray of water and waited for the process to occur.

                     Before                                                            


                   
                                                                      After





Wow! All the Inc spread all over the filter paper.


So in this lab the Inc spread all over the filter paper because it was sperating the molecules in the Inc to make a specific color.

We have now experincesd the seperation technique of Chromatography.

Chromatography is the separation of molecules through passing liquids.
