The universe is consistantly expanding
The ancient Greek philosopher Pythagoras is credited with first proposing that the Earth was spherical around 500 BC. This idea was later supported by Aristotle and eventually confirmed through empirical evidence by astronomers like Eratosthenes.
Plate tectonics is a well-established scientific theory, supported by a large body of evidence, and is no longer in the experimental stage. It is now considered a fundamental concept in geology and Earth science.
The "Martian canals" originally thought to be evidence of a complex network of waterways were later found to be an optical illusion. These features observed by early astronomers were likely due to limitations in their equipment and interpretation of what they were seeing on the Martian surface.
Evidence.
Belief is a personal conviction in the truth or existence of something without necessarily having proof. It involves accepting something as true based on trust, faith, or personal experience rather than objective evidence.
There has been a lot of speculation about other universes, but it is just that: speculation. There is no firm evidence that other universes actually exist. Nor, for that matter, is there any firm evidence that other universes DON'T exist.
there is a theory that there are. the choice is up to you! Einstein said that Schwartzchild wormholes may be a gateway to alternate universes the math is quite complicated but on paper it is quite possible ------------------------------------------------------------------------------------------------------------ Theoretically, we do have parallel universes, and some [although not alot] of evidence supporting this theory has come up. Actually, even though the notion seems entirely ludicrous, there is some serious math behind the parallel universes theory or the many-worlds interpretation.
Experimental evidence is data obtained through conducting an experiment. For example, if I measure the boiling point of a substance at 500 degrees Fahrenheit by boiling the substance, 500 degrees is my experimental evidence.
Hypothesis.
Democritus did not have experimental evidence to support his idea of the atom. Instead, his idea was based on philosophical reasoning and speculation.
Physics is considered a a experimental science because much (70%) of physicists work is conducting experiments. Experiments are used to test relationships and theories. The result of the experiments weed out theories and support theories, other experimetns test rhe range of a relationship.
Ancient Greek philosophers such as Democritus and Leucippus did not have experimental evidence to support their theory of the atom. Their idea of the atom was purely philosophical and lacked experimental verification until much later.
Yes.
The moon
No different than within a single universe.See also:Can you show that God exists?
Nobody knows. There are ideas that there many be many universes such as ours. There is no evidence that there is anything else.
The existence of multiple universes is a theoretical concept in physics, such as the multiverse theory. Some formulations of this theory suggest the possibility of parallel universes or alternate realities, but currently, there is no empirical evidence to support the existence of other universes beyond our own. It remains a topic of ongoing scientific investigation and debate.
