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.
The observable universe is a sphere about 29 gigaparsecs in diameter. We don't know what's beyond that, and it's more of a philosophical question than a scientific one whether two regions of space that can never have interacted because of the speed of light limitation are part of the same "universe" or not.
Astronomers say the Universe is possibly infinite in size, but we can only see the "observable Universe".
The Big Bang was about 13.7 billion years ago.
There are different ways of defining the size of the observable Universe, but it must be at least about 13.7 billion light years in radius. That's a diameter of about 27.4 billion light years.
That's a lot less than 29 gigaparsecs, which is about 94.5 billion light years.
If you allow for the fact that distant objects we see have moved away since their light was emitted, then 29 gigaparsecs is a reasonable estimate for the diameter of the observable Universe.
13.7 billion light years is the visible universe across but it can be larger we can can`t see it the light has not reached us yet and sinds there are infinite things it has to end somewhere
about 15 billion light years

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.
Some astronomers enjoy debating fine points of the Big Bang theory, but virtually all astronomers and astrophysicists accept it as the likely origin of our current universe.

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

radio waves. Of course they also use very big optical telescopes.
The universe has been continuously growing since the Big Bang, and there is no way to accurately measure it, so no. Comments: In fact astronomers have estimated the size of the "Observable Universe". They say there's probably a lot more that we can't see. The Universe is about 13.8 billion years old. That gives the maximum distance we can observe as 13.8 billion light years. But while the light from the "edge" of the Observable Universe has been travelling to us, the Universe has been expanding. Astronomers have estimated how far away that edge is NOW. The usual estimate given for the "real" radius of the Observable Universe is about 46 billion light years.
