Current theories would suggest, yes and yes.

If space does end, what is at the end?
It can't have always existed. Everything has a beginning.

You just keep going, until you hit a brick wall.

Space is relative to time.

Where's brian cox when you need him.
This is a question with no accurate answer IMO, nobody really knows the answer.

The universe fascinates me.
If anybody is interested in the history Of our universe and how we came to be 'here now' you can go no wrong with reading 'A short history of nearly everything' by Bill Bryson.
Its a contender for best book ever written. It explains the whole world of physics, chemistry and biology in a simplistic, easy to understand format - It should actually be the core book on science secondary school science syllabus's - it makes it fun.
Try the first few pages (about the creation of our universe) here. I promise 90% who read it WILL buy the book...

If space is infinite it can't have an end. If it's not infinite there must be something that's not space beyond it. Therefore the semantics hang on what is defined as space.
Is "absence of space" therefore space?
Similarly "time" is a relative construct of the time/space continuum - it only exists where matter exists so "always" is relative. The way to answer it is to decide for yourself if "something" (i.e. space including matter and therefore time) was created out of "nothing" - or not.
We can see something being created out of nothing in a vacuum where the sudden and random appearance of particles has been observed.
Whether or not they are coming from another something e.g. a dimension that we don't yet understand (where does anti-matter exist?) or are literally just appearing out of nowhere having been given mass without any ingredients, nobody knows as yet.
But if something is actually created out of nothing then the bigger question is "what caused it to happen" i.e. what was the creative force that changed inertia into activity? Without a creative force to act as a catalyst, nothing would remain nothing.
And that's where the concept of God comes into the equation.
So maybe there is space as we know and define it i.e the cosmos of "things and the spaces between and beyond them" and space as we don't know it (anti-matter, presumably in a different dimension as matter disappears down black holes and literally vanishes) and the two states fluctuate, with a creative force driving the ongoing changes of state between one and the other?
Nobody knows for sure as we humans are only equipped to sense our reality (and we don't do that particularly well).

Time and relative dimension in space!
