This is something that i was told recently,this is not a subject i know alot about,but find really interesting! can you send atoms back in time?

This is a very common misunderstanding of quantum mechanics. They are many properties of atoms and subatomic particles that can differ depending on the way they are observed. But, consciousness is NOT the relevant variable. The nature of the equipment used to make the measurements is quite relevant.

Atoms, Time ,Space etc..appear differentIly depending on the status of the observer.
If the observer's eyes are cockeyed ,he will see the Universe also that way. If the observer has a closed mind and one tract mind at that ,He will see the universe in the same way.
Therefore you are correct.
TIME OBSERVATION
Time must be understood for what it is. It only describes how fast a phenomena is taking place. If the Phenomena is not taken place no time can be measured. So time has only meaning if a phenomena is taking place. There is no forward or backwarks. The phenomena either occurs or it doesnt occur. There is no in between in Time.
If the formation of the Universe took place as a phenomena then a time measurement would be necessarry to be made. And from an observer at that instance time would be very short.
However from an observer on the Earth after Creation Time appears looking back as a dilated Time.

The behaviour story goes like this.

Atoms are very very small, so small we can't see them directly. If we want to know where one is we have to see its affect on something else. This usually means stopping it or firing something at it like particles of argon gas and see them bounce off. This is called the observer effect and means the atom is no longer happily going about its business as we have either hit it really hard or put something in its way.

The thing about time is that some physical theories (perturbation theory) can be explained more easily by constructing a theory where particles travel backwards and forwards in time. In feynmann diagrams the behaviour of a particle traveling backwards in time is exactly the same as that of an anti-particle traveling forwards in time. However, so far as I know no one has been able to prove such a theory one way or the other. We would have to find something that would be different between the outcome depending on whether it is true or not.

This is called the Feynmann-Stueckleberg interpretation because it occurred to Richard Feynmann and Ernst Stueckleberg independently. This proves the theory that great minds think alike - although (of course) it also proves that Fools don't differ.

This has beem proven hundreds of times since the 1960's in the laboratory, by spilitting a light beam into sparate photons so that one stays in a box and the other takes a different path.

When one of the photons is observed the other photon instantaneosly changes to have the same characteristics as the one observed, indicating that the two are indeed connected.

This is the basis of all physical theories on the nature of the universe (well, almost all, but some people still refuse to believe it) that every pair of particles is somehow connected, even though it may be billions of light years away. Most mathenaticians have now abandoned reality principles and seem to be attracted to string theory now which is gaining acceptance, even though it has not yet been proved,

We don't. It's a postulate by Dr. Planck. He says when you observe something you change its nature.

It's not even truly a theory, it's a postulate.

It says if you measure it, if you observe it, if you take readings of it you change it.

Even if it's unaware of the process.

When I had surgery they came in and took and EKG of me. That's an electronic measurement of the heart. The put all sorts of gismos on my chest and wrist and it scared me and my heart beat changed from 90 to 120.

The Technician said this is somewhat normal.

The fact I was aware of this measurement process changed my normal behaviour into a super abnormal behavior.

Now, when you go into a store and look up and see a security camera, it has an effect on you.

Now, to be frank, if this process is correct then Astrology may also be correct for Astrology says the position of the planets has an effect on you. The gravity wells and mass bodies exhert different effects based on their distances.

So Planck's view is everytime someone looks at a planet or star through a telescope they have a small effect on that planet or star.

And if you think about it, this is true.

Normally the photons of light just hit the Earth, but when you look through a telescope you focus and amplify those photons and they hit your eye and affect your brain and thus change the NATURE of thing on a very microscopic scale.

Planck's view is somewhat akin to the Butterfly effect. A butterfly flaps it's wings in the Amazon Jungle and there is a Hurricane in Florida as a result of that little action.

This is also known at the Chaos theory.

While some will argue with me over this comparison, it is, if you look at it objective, a similar phenomenon.

Cause and effect.

A bug slams into your windshield on the highway and as a resulting chain reaction a Star goes Nova sooner than it would have otherwise.

That is the Butterfly effect carried to extremes.

The theory also meets with STring Theory, which says ALL THINGS in the Universe are made up of little microscopic strings that vibrate.

Change one element and the symphony is altered.

Put your finger into a pool of water, wait 5 minutes and have someone throw a stone. The waves from the stone flow until they hit your finger and then they change.

Your finger affects the flow of waves in the pool.

The theory on global warming is one day we will start one too many manufacturing facilities or one too many cars and the ecosystem will be ruined beyond natural repair and thus the begining of the end occurs.

The day we used up MORE 02 than the system can replenish is the day 02 becomes and "endangered spieces."

That's the theory.

This is all about CAUSE and EFFECT.

Planck's view is the Peeping Tom concept.

You stare out your apartment window at a girl's bathroom window. If she's an exhibitionist she may tend to flaunt it becasue she feels a presence. If she's shy for some reason she'll turn her back to you or draw the curtains.

If no one is watching she's free to be.

That's the Planck view.

It has merits. But it's hard to prove.

The person who was talking to you was probably referring the the observer effect in physics. Read the Wikipedia article. It does not mean that atoms are conscious of being observed but that the act of observation, which needs physical interaction with the object, may change its behavior.

On your second question -- atoms cannot go back in time.

Well, it's not so much about atoms, but the particles that make them up. A group of electrons orbiting an atom's nucleus, say, have particular properties.

But, if you try to *measure* that property (let's say you wanted to find *exactly* where an electron is, for example) By measuring it's location (or weight, or diameter, or charge, or whatever), you have to isolate that electron - and therefore, you change it's properties - such that, the property you want to measure causes a particular effect... but when you compare your measurement to the effect it's causing - it's not equal.

YES! I won't mention any names, but there is a certain contact south of NY and I just get very frustrated when she does that! I mean, I just get used to her character, and just because of St. Patty's Day, she has to go and change her name. I love green though. I would still meet her down at the local pub, though!

could be possible to change the behaviour of atoms because thoughts have energy or you can call brain activity with e.e.g(Electroencephalography). I don't know if anyone can do it.

I don't know the answer for second question.

One cannot observe something without interacting with it in some way. For us to visually observe something, light from it must hit our eyes, which mean the object must either emit energy (which causes it to change state in some way) or reflect energy (which means we must direct energy at it).
