there is no PROOF... notice the words they always use... MIGHT BE... PREDICT... THEORY OF RELATIVELY
these are not FACTS.... i mean shyt... it's the BIG BANG THEORY... even parts of evolution are still THEORY
The scientific definition of the word "theory" is different from the colloquial sense of the word. In the vernacular, "theory" can refer to guesswork, a simple conjecture, an opinion, or a speculation that does not have to be based on facts and need not be framed for making testable predictions.
However, in science, the meaning of theory is more rigorous. A scientific theory is "a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment."[24] Theories are formed from hypotheses that have been subjected repeatedly to tests of evidence which attempt to disprove or falsify them. In the case of evolution through natural selection, Darwin conceived the hypothesis around 1839, and made a first draft of the concept three years later in 1842. He discussed this widely with many of his intellectual companions, and conducted further research in the background to his other writings and work. After years of development, he finally published his evidence and theory in On the Origin of Species in 1859.[25]
in other words... it's just a well-substantiated thought.... but cannot be proven to be 100% fact like "water is wet" "1 plus 1 equals 2"
scientists BELIEVE these things might be true... but cannot prove it and make it happen 100% of the times they attempt it.. so they come with predictions and theories... but still legally, have to be very careful of their words, cause it's still not fact
they have to adjust clocks on satellites because of this
