There are two kinds of limits in scientific research:
1.
Theoretical or intrinsic limits: when
these limits exist, no matter how many scientific discoveries may be made in
the future, they won’t be exceeded.
2.
Practical limits: they
appear when, in theory, a problem can have a solution, but there are practical
reasons that make it impossible, at least for the time being. In these cases,
we cannot affirm that the problem won’t be solved in the future.
Sometimes we don’t know if a given limit is theoretical or practical. In these cases, what will happen in the future is open. If the limit turns out to be theoretical, it will never be exceeded. If it is practical, it will be exceeded if our technical capabilities exceed the technical needs for its resolution, being possible that this will never happen. Take, as an example, the inherently difficult math problems I mentioned in the previous post.
