Is it possible to drop a fishing line to the bottom of the deepest ocean?

I marked it as a great question because I want to see some answers.

Physics, science

I don’t know the answer but it makes me wonder: do scientists really know how deep the deepest ocean is? I was thinking they had a hard time even getting machines down there.

I think there are parts of the ocean so deep we have not even seen what is down there. There are creatures we don’t even know exist living that deep. That was my understanding anyhow. So I don’t think u could drop a fishing line that deep. I think it would get swept away or tangle.

From what I’ve read and heard, this has not been accomplished. The line would have to be rediculously long and there would have to be some kind of sensor on the bottom of it to know when you’ve hit the end. This sensor would also have to be able to resist intensely high temperatures due to the core of the earth being so close.

It isn’t going to happen and anyone that has asked this has no idea how deep the ocean is.

I just wanted to mention that the Mariana Trench is the deepest part of the ocean on record.

The most accurate measurement on record was taken by a Japanese probe, Kaikō (かいこう), which descended unmanned to the bottom of the trench on March 24, 1995 and recorded a depth of 10,911 meters (35,798 ft)

I just wanted to add my 2 cents in. I know this is an old pretty much dead question.

If your fishing line is long enough, you can easily drop your fishing line to the bottom , providing you have a heavy weight at the bottom of your line.
