Or is there a boundary for the universe?

No, the universe is said to be no ending. Perhaps we human can't go there, so they came out with this theory. But science is science, you need evidence to prove it.
However, the universe is said to be a spherical shape. Thousand or even millions of galaxies are in there. It is believe that the universe will one day compress into a compact form which return its situation likely before the big bang.

No.
Acoording to the current model, after the Big Bang there was an inflationary phase where the universe expanded faster than light.
As a consequence, the entire universe is larger than the observable universe. As we can only measure things within the observable universe - measurement is observation - it's not possible to measure the diameter of the universe.
(Irrespective of whether the universe warps back into itself at that.)
Edit: I should mention, too, that scientists have tried indirect methods of inferring the radius/diameter of the entire universe, but that only yields a lower boundary.

The universe has no boundary. It is forbidden by General Relativity.
The part of the universe we can see (the "observable universe") has a radius of 13.7 billion light-years, since that is the age of the universe, so light has only had that much time to get to us.

It's possible to set up a time line for the size of the universe.
The first massive stars lit up about 100 million years after the beginning.
They became super-novas after about 10 million years.
The debris from these explosions crashed into the surrounding hydrogen field a million or so years later,causing the formation of thousands of solar systems,ours was one of them.
Our earth and solar system arrived to now in about 4.5 billion years.
This gives us a universe that may be 5 or 6 billion light years in radius enough time to reside in the outer arms of a spiral galaxy and enough time for the spiral galaxy to collapse and go out of existence.
The universe is about 6 billion light years in radius but it could be much older.
The farthest galaxies we see don't exist to-day.

Not really sure. It appears the consensus is about 10 billion light years. However, estimates range from 10 billion to 156 billion light years.

Think of racing against a NASCAR car while you are on foot. The universe grows bigger in that rate...

look from neuton we find energy cannot be cerated or destroyed.now if u thing every planet is a body of energy
so it cannot be destroyed nor can be created.but it is possible to shange the form of energy .So yes it has a boundry but scientist yeat couldent discover it .

no, the universe extends beyond the known universe.
