“We could tell them [alien civilization] things that we have discovered in the realm of mathematical physics, but there is stuff that I would like to know. There are some famous problems like how to bring gravitation and quantum physics together, the long-sought-after theory of quantum gravity. But it may be hard to understand the answer that comes back.” KnowsMayLongHardProblemTogetherStuffAnswersTheoryCivilizationPhysicsAliensMathematicalRealmsGravityQuantumQuantum PhysicsGravitation Author:Paul Davies

“Scientific theories need reconstruction every now and then. If they didn't need reconstruction they would be facts, not theories. The more facts we know, the less radical become the changes in our theories. Hence they are becoming more and more constant. But take the theory of gravitation; it has not been changed in four hundred years.” IfsKnowsNeedsYearsFactsWould BeChangeFourChangedTheoryBecomingHundredConstantRadicalNow And ThenBecoming MoreReconstructionScientific TheoryGravitation Author:Charles Proteus Steinmetz
“The test of science is not whether you are reasonable—there would not be much of physics if that was the case—the test is whether it works. And the great point about Newton’s theory of gravitation was that it worked, that you could actually say something about the motion of the moon without knowing very much about the constitution of the Earth.” IfsEarthCasesKnowingTheoryMoonTestsConstitutionPhysicsReasonableNewtonGravitation Author:Hermann Bondi
“My opinion about Miller's experiments is the following. ... Should the positive result be confirmed, then the special theory of relativity and with it the general theory of relativity, in its current form, would be invalid. Experimentum summus judex. Only the equivalence of inertia and gravitation would remain, however, they would have to lead to a significantly different theory.” ShouldDifferentWould BeFormResultsOpinionSpecialTheoryCurrentsFollowingExperimentsRelativityInertiaGravitationTheories Of RelativityPositive Results Author:Albert Einstein

“A priori one should expect a chaotic world which cannot be grasped by the mind in any way... The kind of order created by Newton's theory of gravitation...is wholly different. Even if the axioms of the theory are proposed by man, the success of such a project presupposes a high degree of ordering of the objective world.... That is the "miracle" which is being constantly reinforced as our knowledge expands.” IfsMenWorldWayShouldMindKindDifferentOrderTheoryDegreesProjectsMiracleObjectivesNewtonChaoticAxiomsGravitation Author:Albert Einstein
