Hopefully we will learn how the universe was created.

I have been thinking about this for some decades. For example, X-rays of objects, such as part of the body, are not photograghs, they are photograms. A photograph focuses the rays and produces an image, the simplest example is holding a magnifying glass above a white surface to focus the ambient light.

X-rays have a wavelength that is very short.

At the other extreme is radio, which has a long wavelength. In fact, there are 'telescopes' on Earth that are over a thousand miles long! It is an array of antennas that run along the ground for miles.

As Albert Einstein said, "the most incomprehensible thing about the universe is that it is comprehensible".
