1. hypothesis

   A hypothesis is a statement of what is deemed possibly true, assumed and reasoned upon as if certainly true, with a view of reaching truth not yet surely known; especially, in the sciences, a hypothesis is a comprehensive tentative explanation of certain phenomena, which is meant to include all other facts of the same class, and which is assumed as true till there has been opportunity to bring all related facts into comparison; if the hypothesis explains all the facts, it is regarded as verified; till then it is regarded as a working hypothesis, that is, one that may answer for present practical purposes. A hypothesis may be termed a comprehensive guess. A guess is a swift conclusion from data directly at hand, and held as probable or tentative, while one confessedly lacks material for absolute certainty. A conjecture is more methodical than a guess, while a supposition is still slower and more settled; a conjecture, like a guess, is preliminary and tentative; a supposition is more nearly final; a surmise is more floating and visionary, and often sinister; as, a surmise that a stranger may be a pickpocket. Theory is used of the mental coordination of facts and principles, that may or may not prove correct; a machine may be perfect in theory, but useless in fact. Scheme may be used as nearly equivalent to theory, but is more frequently applied to proposed action, and in the sense of a somewhat visionary plan. A speculation may be wholly of the brain, resting upon no facts worthy of consideration; system is the highest of these terms, having most of assurance and fixity; a system unites many facts, phenomena, or doctrines into an orderly and consistent whole; we speak of a system of theology, of the Copernican system of the universe. Compare SYSTEM.

1. Nick Pope:

   Im more interested in the fact that this first photo has been leaked, and in the related leaking of information about the Pentagons Unidentified Aerial Task Force, where serving intelligence community personnel have shared insights from two intelligence positionreports, with my own defense background in this subject, three things stand out. Firstly, the description by one insider of the reports as shocking a wordthat begs the question what about UAP do these people find shocking. Secondly, the fact that the intelligence reports seem to have been given a surprisingly wide distribution in various intelligence agencies, and thirdly, the fact that the extraterrestrial hypothesis seems genuinely not to have been taken off the table.

2. Steve Cohen:

   Our hypothesis was that they are the same, but most affluents are not luxury travelers, simply because someone has a particular income, doesn’t make them a luxury traveler. And even those among high-income consumers who have taken a vacation, aren’t necessarily taking luxury trips.

3. Philipp Heck:

   We have more young grains than we expected, our hypothesis is that the majority of those grains, which are 4.9 to 4.6 billion years old, formed in an episode of enhanced star formation. There was a time before the start of the solar system when more stars formed than normal.

4. Scott Roberts:

   There’s one hypothesis from a prominent mycologist who suggests that the reason the body’s temperature is 98.6 is because that is the temperature where fungi can’t grow that well. And so, now we’re seeing Candida auris and some of the other new microbes that have come up that really grow quite well – even at temperatures of 98.6 in the human body. And so I think climate change, really selecting for these organisms to adapt to a warmer climate, is going to increase the odds that there’s infection in humans.

   CNN earning an award for coverage of the coronavirus outbreak, despite getting it wrong on masks, the lab leak hypothesis, transmission of the virus and more? ‘Nightline’ winning an award for the kidnapping plot of Governor Whitmer, which we’ve since come to find out involved more FBI agents and informants than actual perpetrators? You’ve got story after story listed for awards that not only got material facts wrong but for which other outlets did a far better job of getting the truth.
