But, you know, the existence of exoplanets, planets outside the solar system was considered speculative when I started doing astrophysics about 40 years ago.
And for, you know, 40 years, not much time was allocated on telescopes to looking for such planets.
Now you might say, well, eventually it was discovered, yeah, but it took 40 years.
And also the cell phone would have served a very important role because Moses went for 40 years in the desert before he got to the close to the promised land.
