So Mr Sesame, ref. your assertion
" Matter cannot be created, nor can it be destroyed ",
and " Similarly, Energy cannot be created or destroyed, it only changes form "

WHAT HAPPENS WHEN MATTER MEETS ANTIMATTER ? ( The existence of both has been proved experimentally )

I'd be interested to see the theoretical Interaction Equations.

Oblige me please.

E = mc²

The reaction of 1 kg of antimatter with 1 kg of matter would produce 1.8×1017 J (180 petajoules) of energy (by the mass-energy equivalence formula E = mc²), or the rough equivalent of 47 megatons of TNT.

The above is from http://en.wikipedia.org/wiki/Antimatter

Are the SI Units (like kg and J) so unknown in the USA, that you have to link them?
Why USA, Burma and Liberia don't accept le Système international d'unités, like everyone else?

Gasp, do you think as true Americans we are going to accept socialist commie pinko things like the metric system?

[Tread]

OK I'm pulling back the question, I fit is necessary to post Links.
It has nothing to do with them. They are only able to use the right system.

The metric system is much more scientific than the ounce pound foot mile hodge podge.

The metric system progresses in Tens. Its clean and uncomplicated.
mili centi deci meter deca hecto Kilo
Perfection!

Old English system: Jumps in threes and twelves... usually

1 digit=3/4 inch
1 Nail=3 digits = 2+1⁄4 inches = 1⁄16 yard
1 palm=3 inches
1 foot=13 inches... 12 inches from 1066AD onwards!
1 cubit=From fingertips to elbow, 18 inches.
1yard=36 inches
1 fathom= left fingertip to right fingertip with arms outstretched= 6 feet (not always!! )
1 rod=16 1/2 feet, used to be 20 feet earlier.
1 furlong= 660 feet=40 rods
(One plough's furrow long; in Saxon, furrow =furh)
1 mile=1760 yards= 5280 feet=8 furlongs... after 1066ad, became 5000 feet.

You see, its like some private measuring system going haywire! Those ancient barters and farmers didnt care about science or measurement standards. They managed with whatever they had, palms, hands, feet, ploughs even!

Do you think NASA uses this mad system in it's space programs? No. They use the metric system for scientific endeavours.

What was it then with the Mars Climate Orbiter 98? Ok, it was a NASA subcontractor from Lockheed Martin.

These statements are illogical and utterly Unscientific. There are scores of things that we know nothing about. But our ignorance cannot hinder their existence. Take for example, the Radio waves. Nobody knew about radio waves before Heinrich Rudolf Hertz discovered them in 1888 AD; Yet they have existed in full glory since the beginning of this Universe!

We cannot prove the existence of God or, Soul with our scientific instruments. But that doesnt disprove the existence of such an entity.

Yes, anyone can believe in anything... but that doesnt make it real or unreal. The Truth remains as it is.

Nasa software uses metric... especially after the units mix-up with the mars orbiter. But Nasa hardware often uses english because their tools and machines are still in english. It would be a huge expense to retool their shops.

It didn't go boom, it just didn't didn't enter mars orbit and kept on going because of mistakes with english vs metric units.

I'm going to get on my Nasa soapbox now. Yes, Nasa learned a lesson from that, and from the shuttle accidents. But the real lesson to be learned was with congress, and it certainly fell on deaf ears. I've heard a lot of complaints against Nasa. The shuttle is too expensive. They have too many accidents. They don't have their eye on the real mission - sending people to mars. Well the problem all along has been with congress and presidents. Nasa knows how to reduce costs in the shuttle. They can reduce accidents, and they would love nothing more than to send humans to mars. The problem is lack of funding. Congress and the American people would like nasa to do all these things, but Congress & presidents won't pay for it.

The shuttle has high operating costs because they were short changed during the development of the shuttle. So they skimped on design and shifted the costs to operational costs. The shuttle had to prove to be cost effective so they had to have a high flight rate and launch satellites that could have been launched by unmanned rockets. So they didn't listen to engineers that said it was too cold to launch Challenger.

They also skimped on testing because there were no funds for testing. Testing that would have shown the real dangers of falling debris which led to the Columbia accident.

So did congress & Bush learn from past mistakes? No. Bush proposed a new program called Vision for Space Exploration. The program is fantastic, and exactly what our country's space program needs to make huge advances. All the rockets required are being developed under a program called Constellation. The aim is not the moon, not mars, but for Nasa to learn how humans can travel, live and work throughout the solar system to exploit literally new worlds of resources. Bush can't even provide full funding for his own plan. Again Nasa is having to skimp on design which will translate into higher operational costs, and possibly lives of future astronauts. Democrats in congress criticized him on underfunding Nasa throughout his terms. So what do the democrats do now that they are in charge? Rather than correcting Bush's mistake of underfunding Nasa they throw together the Augustine Commission with the initial goal of declaring Ares I (the launcher for the new capsule) as too expensive. It is clear that congress will NEVER learn the consequences of underfunding space programs. This is rocket science... it's going to take some dollars. To fully fund the Constellation program would take another $3 billion per year. Congress belched out $2 billion for the cash for clunkers program like it was chump change, and Obama just spend about $2 trillion on BS programs. Don't get cheap now. Nasa's budget is just .5% of the nations budget. And on top of Nasa's budget, lawmakers tacked on an extra $750 million in pork barrel spending for their districts - for things like a dinosaur museum and other non-Nasa business.

Look at this:
http://www.nasa.gov/mission_pages/co...s_aug09_1.html

This is the Ares 1-X launcher that's assembled and ready to go within a couple of months. It's the first test Ares launcher and it could very well get canceled before it can even launch.

[Jenae LaTorque]

The Mars Climate Orbiter was intended to enter orbit at an altitude of 140-150 km (460,000-500,000 ft.) above Mars. However, a navigation error caused the spacecraft to reach as low as 57 km (190,000 ft.). The spacecraft was destroyed by atmospheric stresses and friction at this low altitude. The navigation error arose because a NASA subcontractor (Lockheed Martin) used Imperial units (pound-seconds) instead of the metric system.

went boom = destroyed

Amen to the rest of your statement!

Although I got a chuckle out of Randolph's reply; the answer is; No, they are not so unknown. As I stated below that, it was from a Wilkipedia page. When I copied and pasted; it brought the hyperlinks along with it.

I don't know exactly why the USA never completly switched over to the metric system. I remember that they said we would over 40 years ago when I was in school, but it hasn't happened yet. Right now we have a mixed up system. Think how lucky folks are in other countries. I have to have two sets of mechanics tools just to work on my vehicles.

The progress towards metric usage in the USA is happening; it is just rather slow. Just another example of the "will of the people" in action.
People have a natural resistance to change. Most likely that is an inborn survival trait. They resist change unless there is a clear-cut advantage to it. So far, this country has been able to get by without changing for the most part. Other countries had to change to compete economically. In areas like the sciences; the USA change was instituted long ago. Most of the Federal government has changed to the metric system.

One area that has changed is that alcohol (booze) is sold by the metric system. It is now sold in metric containers with a 750 ml bottle replacing the former "fifths" which were about 757 ml. Beer however is still measured by the old standard ounces like soda pop. Both usually display the metric volume in parenthesis also.

Hey Jenae,
What would happen if I tried to peta your joules?

[Rachel]

After many years of sometimes getting this weird sickness and wondering what it was it was suggested to me to check content labeling. I had purchased a store brand of bread crumbs that I knew didnt have msg. I purchased more in a different flavor ( plain and Italian style) Got sick looked at labels again still none in the plain however the Italian style had it! I've also gotten sick from frozen pizzas that didnt have msg listed in contents but I knew the symptoms so it was in there somewhere.

Homemade cure for food poisoning. I was deadly ill last night. I drank huge quantities of water and vomited 4 times. My fever receded instantly and I felt better. After that I prepared a solution with glucose and salts and kept drinking it to prevent dehydration.

I don't want people to think I am replying for Sesame, or that I am trying to take anything away from Jenae's authorship of this Thread, but it looks as though you have assumed that nothing is left when Antimatter hits Matter.
This is not so. Almost invariably intense Gamma Radiation is created with a very short duration, which is why I would imagine Jenae quoted E=mc2. In fact the velocity of stellar Gamma Ray emissions is far less than the speed of light, which is why it takes a hell of a long time to reach instruments here on Earth, and sometimes never reaches us at all if it is not aligned with our galaxy. Only a small proportion of Gamma Radiation received from space can be accounted for in this way, and Matter-Antimatter interactions in Space are one of the Holy Grails sought by many Astrophysicists.

And yes, the product of Matter-Antimatter interaction is pure energy ( mostly Gamma Rays )

What irritates some Astronomers is the observable fact that some stars apparently self-destruct without any apparent residual radiation ! Spooky stuff eh ?

************************************************** *******
Not sure what you mean by "spooky", and really am puzzled by the Astronomers being irritated by it. I for one can accept that we are limited in our observations by what our senses and instruments can detect. No need to get mad, get even! Build a new theory, based on the data you have, to account for it, and figure out a way to test the theory. Do again and again as necessary until you get it right. Only thus will you achieve harmony and enjoy peace and tranquility.

Oblige me please.

The sumtotal of all matter and energy in the universe is a constant. When matter and animatter collide, the result is not NOTHING, but the release of huge amounts of energy in the form of Gamma Photons. Each gamma photon carries 511 Kilo electronVolts of energy. If you apply E=mc^2, you will see that the matter-energy equation still holds true.

Antimatter~ example
When a very fast proton collides with a Hydrogen neucleus consisting of 1proton only, the proton and it's kinetic energy is converted to a neutron, an antiproton and a meson. The total electrical and the baryon charges are conserved in this materialization.

But the question is, if there is matter(mostly) and antimatter in this Universe, why doesnt it self-destruct?
