less than 100 years ago Dalton published his theory that atoms could not be broken down into smaller particles. Scientist have found out that they can in fact be broken down even further.
One possible conjecture is that the product of two odd integers is 8. A conjecture does not have to be true, nor does it have to be sensible. It must be testable, though. Many conjectures were initially thought to be sensible and true but later proven to be false. And when the false nature is fully understood, in retrospect they no longer appear sensible either!
In a way, yes. Certain "postulates" or "axioms" are assumed to be true; all other statements are derived from those. The "postulates" are chosen so that they are reasonable and simple assumptions.If you try to prove the postulates, you have to derive them from some other statements, so sooner or later, you will always have unproved statements. That can't be avoided.In a way, yes. Certain "postulates" or "axioms" are assumed to be true; all other statements are derived from those.

This question is unanswerable. How can a "statement of truth" be made which "is not true". Truth does not change. It cannot be that something was true when it was said and later it became untrue.
False. "Get the Party Started" was written by P!nk, along with Linda Perry and Scott Cutler, but it was originally performed by the artist Missy Elliott. P!nk later released her own version of the song, which became popular.
False. The purchase day book is not a part of the ledger; it is a subsidiary book used to record all purchases made on credit. Entries from the purchase day book are later posted to the individual accounts in the general ledger.
No, this is mainly due to habitat. However, rumors have been passed round that some have been sited, these were later proven false.
This statement is false. Although the Greeks thought some constructions impossible, not all of the so called impossible problems were later proven to be possible.
Langley's law is it takes less energy to fly once you gain momentum. He based this on a skipping rock or a skater skating on thin ice. It was later proven to be false.
Yes, many were later proven to be impossible.
This is false. Allergies can spring up later in life.
False
From perspective on ground, land (more specifically ocean) was flat, and went on and on, until you fell off the side. This was later proven false, as with airplanes. As you travel up, you start to see more spherical shaping occur.

No. They were not proven to be possible.

im not sure but i think yeah!
