what would happen to a bowling ball if it were to remain truly stationary in a region of space in an expanding universe? assume the experiment will compensate any effect of gravity.
Absolutely - you can use anything you want. I prefer to always define myself as stationary. It's usually easier that way. And it makes me feel special!DARKSYDE said:I believe we could use lots of things in the universe for reference. Pulsars, background microwave radiation, etc.
We know how fast our solar system is traveling with respect to some objects and vice versa: we know how fast they are traveling relative to us. Either can be considered moving or stationary and neither is an absolute or "priveleged" selection. All - ALL motion is relative.and as far as stationary, i do mean relative to our motion. we do know how fast our solar system is traveling as well as our galaxy.
A prediction is a statement about what is likely to happen in the future based on observations and data. It is testable and can be proven to be true or false. A hypothesis, on the other hand, is an educated guess or explanation for a phenomenon that has not yet been proven. It is used as a starting point for further investigation and can be supported or rejected by evidence.
In order to make accurate predictions, scientists use the scientific method which involves making observations, forming a hypothesis, conducting experiments, and analyzing data. They also rely on past research and knowledge in their field to inform their predictions. Additionally, they may use mathematical models and simulations to help make more accurate predictions.
Uncertainty is a natural part of making predictions in science. Scientists account for uncertainty by acknowledging and considering all possible outcomes, using statistical analysis to quantify the likelihood of each outcome, and being transparent about the limitations of their predictions. They may also conduct further research to reduce uncertainty and improve the accuracy of their predictions.
Yes, predictions can be proven wrong. In science, predictions are always subject to testing and can be either supported or rejected by evidence. If a prediction is proven wrong, it means that the hypothesis or assumptions on which it was based were incorrect or incomplete. This can lead to further research and refinement of the prediction to improve its accuracy.
Predictions are used in a variety of real-world applications, such as weather forecasting, market trends, and medical diagnoses. In these cases, predictions help make informed decisions and prepare for future events. Scientists also use predictions to inform public policy and decision-making, such as predicting the impact of climate change on ecosystems. However, it is important to note that predictions are not always 100% accurate and should be used in conjunction with other information and data.
