There is no end. They Universe is always expanding due to the big bang.

No, the Universe actually closes in on itself. If you left from here in any direction, and you went far enough and fast enough, you would arrive right back here.
In any case, the Universe does not have any boundaries.
Astronomers conclude that objects in the universe are moving away from Earth due to the observed redshift in their spectra. This supports the idea of an expanding universe, as described by the Big Bang theory. The amount of redshift is proportional to the distance of the object, allowing astronomers to estimate the speed at which galaxies are moving away from us.

The universe is a vast and mysterious place that never ceases to amaze astronomers and scientists.
The Big Bang

Unknown - As they can't easily be detected, and most of them are expected to have been formed upon the onset of the Big Bang. Astronomers estimate that in our region of the Universe, there are some 100 billion supermassive black holes. But this does not account for the lesser size black holes, of which there is estimate to be a much larger number.
people who study about the universe are called astronomers
Astronomers believe the universe began with an explosion, known as the Big Bang, because of the observed expansion of the universe, the cosmic microwave background radiation, and the abundance of light elements like hydrogen and helium. These pieces of evidence support the idea that the universe started from an incredibly hot and dense state about 13.8 billion years ago.

Unlikely, because that number is only someone's estimate.

radio waves. Of course they also use very big optical telescopes.
Perhaps in the future astronomers will do all the redshifts of the 100 billion galaxies in the universe.
