How many current theories of the universe began with observations?
Most current theories of the universe, such as the Big Bang theory and the inflationary theory, began with observations of the cosmos, including the cosmic microwave background radiation and the distribution of galaxies. These observations have provided evidence that scientists have used to develop and refine these theories.
When can scientific theories be changed or replaced?
Scientific theories can be changed or replaced when there has been significant evidence for the change. The scientific method must be used to create a new hypothesis, which must then be proven.
What do scientist need to do to prove something?
If they are mathematicians they can prove a theorem. In the physical sciences theories cannot be proved. The current theory is the one that fits the experimental evidence more closely than all alternative theories. When a new theory comes along that is more accurate, the old theory is superseded.
Age of the universe?
in the neighborhood of 14.5 billion years, from current evidence
How material science or modern science dare to consider the authority for truths in this world?
Authority is based on experimental outcomes. When two competing theories predict different outcomes for an experiment, the experiment is conducted and one (or both) theories are demolished. The only authority is the result of methodological testing, NOT simply the say-so of some scientist or some divine revelation. You yourself may overturn any current scientific theory simply by demonstrating, through a properly controlled experiment, why the prevailing theory is wrong.

How have scientific theories changed over time?
Scientific theories have changed over time as new evidence is discovered through experiments and observations. As technology advances, scientists can gather more accurate data and refine their theories accordingly. Additionally, the acceptance and rejection of ideas by the scientific community also influence the evolution of scientific theories.

What is the current conflict in Portugal?

Yes
What is the current conflict in Cuba?

Are tachyons possible?
The existence of tachyons, hypothetical particles that travel faster than the speed of light, has not been confirmed. Current theories suggest that tachyons would have imaginary mass and could violate causality, leading to paradoxes. As of now, there is no experimental evidence supporting the existence of tachyons.
What is a current conflict in the US?
Economy
What can't science answer questions with but can give us the answer based on the knowledge at the time?
I'm not exactly sure what kind of answer your looking for, but if your asking about decisions made based on scientific evidence. The reason statements are based on "Knowledge at the time" is because later evidence or findings might cancel out the current decision. scientific answers are based on the exploration of theories, and until all theories can be exhausted, there cannot be a single answer to the given question.
Is there a corner to the universe?
Not if the current theories about its origin and developments are correct.
What is evidence that an electrical current produces a magnetic field?
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
