Which statement about scientific knowledge is true?
The correct answer is D. Scientific knowledge can change with new evidence. Explanation: Scientific knowledge refers to the knowledge and understanding scientist obtained about the world using the Scientific method that includes stages such as observing, creating a hypothesis, testing, etc.
Why is the scientific method not accurate?
Documentation of experiments is always flawed because everything cannot be recorded. One of the most significant problems with the scientific method is the lack of importance placed on observations that lie outside of the main hypothesis (related to lateral thinking).
Can a scientific theory be proven true?
A scientific theory is not the end result of the scientific method; theories can be proven or rejected, just like hypotheses. Theories can be improved or modified as more information is gathered so that the accuracy of the prediction becomes greater over time.
How can a fact be proven?
The usual test for a statement of fact is verifiability—that is whether it can be demonstrated to correspond to experience. Standard reference works are often used to check facts. Scientific facts are verified by repeatable careful observation or measurement by experiments or other means.
Can a factual statement be false?
Factual statements surely are corrigible in the light of further evidence. For factual statements are just the true or false answers we give, or could give, to questions of fact, or to possible questions of fact. But a statement of fact cannot be false.
What is scientific proof?
Scientific evidence is evidence that serves to either support or counter a scientific theory or hypothesis. Such evidence is expected to be empirical evidence and interpretable in accordance with scientific method.
Why is space flat?
In a universe with zero curvature, the local geometry is flat. With dark energy, the expansion rate of the universe initially slows down, due to the effect of gravity, but eventually increases. The ultimate fate of the universe is the same as that of an open universe. A flat universe can have zero total energy.
How far down does space go?
In the 1900s, Hungarian physicist Theodore von Kármán determined the boundary to be around 50 miles up, or roughly 80 kilometers above sea level. Today, though, the Kármán line is set at what NOAA calls “an imaginary boundary” that’s 62 miles up, or roughly a hundred kilometers above sea level.
