Nothing in that article casts any doubt on the existence of gravity.
Quinn stating: “We should be able to measure gravity.” - seems to cast huge doubt on the existence of gravity, considering that is a full admission they cannot measure it.
You cannot just isolate this sentence out of the entire document and claim that it implies that gravity does not exist.
It is the same as me taking into isolation "seems to cast huge doubt on the existence of gravity" and say that Action80 wrote that it only seems to cast doubt on the existence of gravity so Action80 supports that it does not cast doubt on the existence of gravity.
Edited for clarity.
I do not believe a more feeble attempt to communicate a point has ever been made here on this forum.
Regardless, Quinn stating "We should be able to measure gravity," doesn't imply anything.
It admits that gravity cannot be measured and has not been measured.
From that, I can infer gravity doesn't exist.
If you read the entire article you will see that he only means that they should be able to measure gravity more accurately.
Your attempt to say that he means that they cannot measure gravity at all sounds much more feeble than my comment actually.
Again, you have no basis on which to interpret the statement, "We should be able to measure gravity," as somehow containing the words, "more accurately."
I am not attempting to state what he means.
He stated what he means.
When someone states "We should be able to measure gravity," that means someone should be able to measure gravity.
Further, stating "We should be able to measure gravity," clearly indicates it has not been measured.
Now, if you want to speak for Quinn, I suggest you contact him and do an interview, then ask his permission.
Otherwise, don't.
