Observing changes the outcome how can we observe?

In summary, the conversation discusses the impact of observation on the outcome of events, particularly in the field of quantum mechanics. It is acknowledged that the observer is a crucial part of any observable event, and this has been taken into consideration in scientific discussions and experiments. However, the effects of observation are typically only significant at the quantum level. The conversation also touches on the limitations of human understanding and the idea that the universe existed and behaved in the same way before humans even existed. It is noted that our understanding of the universe is based on present-day quantum theories and that there are still many unanswered questions and theories in the field.

[SOLVED] Observing changes the outcome.. how can we observe?

Since it is now known that the observer is part of ANY observable event, don't we need to redo oh so many so called factual observations?

Is it even possible to observe something without the observer changing the outcome?

No.

No. Since we understand this, and have for about 80 years, this had been taken into consideration. In fact the last 80 of physics have been filled with discussions and experiments designed to test and understand this fact.

It is important to realize that the effects of observing are very, very small, and are typically only significant at the quantum level. We are usually talking about the effects photons on other subatomic particles. There are a couple of schools of thought resutling from Quantum Mechanics that hint at deeper, macroscopic effects, that is effects for large objects, but this stuff is still highly theoretical and but one or two interpretations that compete with about a dozen other theories.

It is true that no observation of any kind can be made with any amount of accuracy, but for a more important reason than the effets of that observation.

We forget sometimes that we view the world with an imperfect tool, and will never even hope to fully comprehend anything we observe. Pidgeons can see geometrical patterns in light, and dolphins can change the frequency of their communications. Face it, we are not all knowing, and can never hope to be.

The universe evolved just fine without any observers [er, us in particular] for a very long time. The universe has also been kind enough to let us watch the video of how it all happened. The fact it is behaving in exactly the same way now as it did long before we even existed, suggests the observer effect is temporal, at best.

How do you know all this? Our understanding of cosmology is based on our present day quantum theories, which are radiacally observational (at least in the most common interpretation). AFAIK the stupid creationist idea that the universe was created yesterday with all its properties, like CMB, and the records of all the scientific experiments all up to date to fool us, is logically undefeatable. Not that I'm proposing it, just suggesting that everything isn't as cut and dried as 19th century scientists believed.
 

1. How does observing change the outcome of an experiment?

When we observe an experiment, we are actively paying attention to the process and collecting data. This can influence the outcome by making us more aware of any errors or biases that may arise, leading to more accurate results.

2. Can observing alter the behavior of the subjects being studied?

Yes, observing can affect the behavior of the subjects being studied. This is known as the Hawthorne effect, where people may change their behavior when they know they are being observed. This can be minimized by using techniques such as double-blind studies.

3. How can we ensure that our observations are objective and unbiased?

To ensure objectivity and minimize bias, it is important to have a well-designed and controlled experiment. This includes using random sampling, controlling variables, and having a control group. It is also important to have multiple observers and to use standardized methods for recording and analyzing data.

4. What role does technology play in observing changes in an experiment?

Technology can greatly enhance our ability to observe changes in an experiment. It allows for precise measurements, real-time data collection, and the ability to record and analyze large amounts of data. However, it is important to use technology appropriately and to also rely on human observation and interpretation.

5. How can we use observations to improve future experiments?

Observations can provide valuable insights for improving future experiments. By analyzing the data and identifying patterns and trends, we can make adjustments to our methods and variables to increase the accuracy and reliability of our results. Additionally, sharing our observations with other scientists can lead to new ideas and collaborations for future experiments.
