Hi there.
00:02
This question is asking about science in general.
00:09
Science is a field of knowledge, but that knowledge is being continually added to through experimentation.
00:46
So the point is, science is not static.
00:53
Even the theory of the atom, the atomic theory that dalton proposed, a lot of that theory was great and still survives today.
01:03
But a couple of the things he said about that, were updated, had to be updated as new knowledge came along.
01:10
The main thing being the fact that dalton said that atoms were indivisible spheres.
01:15
Well, then as technology improved and we did more and better experiments, it was discovered that actually the atom has subatomic particles in it.
01:25
And now we are finding even smaller particles.
01:28
So we are constantly updating that atomic theory as an example.
01:32
So as we look at this question, these experiments, provide new knowledge.
01:38
If this knowledge doesn't agree with the existing theory, what we do, as in the case of the atomic theory, when thompson discovered electrons, the new knowledge is used to reevaluate the theory.
01:57
So i'm just going to shorten that down into the theory is re -evaluated in the frame of this new knowledge.
02:11
So that would be our correct answer.
02:14
As we look at the other answers here, they are definitely wrong.
02:18
For example, letter b, letter b says, the new knowledge is ignored in favor of the old theory.
02:24
Well, that's a really bad idea.
02:26
If that happened, we would not have cell phones today.
02:29
We wouldn't have cars.
02:30
We would just ignore all that and say, oh, you know, horse and buggies are the best.
02:34
And we see that going on now with gasoline cars...
