Like @swamidass I also know absolutely no one where this is true.
Almost 100% of the field recognize that “there is a point (or a time) beyond (or before) which we may not be able to see?”. This is as close to being certain as you can get in science. The easiest example is that faraway (equivalently, when we look far into the past), the Universe expands faster than light. This means that there are parts of the Universe that are racing away from us faster than the speed of light, i.e. the fastest information can be transferred.
