How much of the universe would you say is directly observable?
The term "observable" refers to anything that can be detected or measured using scientific instruments or methods. This includes things that are directly perceived by our senses, as well as things that can only be observed indirectly through their effects on other observable phenomena.
It is currently estimated that only about 4% of the universe is observable. The remaining 96% is made up of dark matter and dark energy, which cannot be directly observed but are inferred from their effects on observable matter and energy.
No, it is not possible to observe everything in the universe. The observable portion of the universe is limited by the speed of light, which means that we can only see objects that are within a certain distance from us. Additionally, there may be parts of the universe that are beyond our current technological capabilities to observe.
The observable universe is constantly expanding as light from distant objects continues to reach us. However, due to the finite speed of light, the observable universe will always be limited by the age of the universe and the distance light can travel in that time.
Scientists use observable data to make predictions by analyzing patterns and trends in the data and using them to develop hypotheses and theories. By testing these predictions through further observation and experimentation, scientists can refine their understanding of natural phenomena and make more accurate predictions in the future.
