Expanding Universe Irony

Current research reveals that not only is the universe expanding, it is accelerating.

One theory is that as it expands the increased vacuum pulls new matter into being. New matter needs more space and is thus pushing the universe apart.

However, there could be a bit of irony involved with the universe's expansion and how the scientists know it's accelerating.

They discovered the universe is accelerating by measuring light from Super Nova's - exploding stars.

These Super Nova's give off the same amount of light when they explode no matter where they are.

And it is thought that these explosions are what sends things like oxygen, iron, etc. throughout the universe. So it comes to fall on places like Earth.

But an explosion is an expansive force - a push apart force - not like gravity which is an attractive force.

Why couldn't these explosing Super Nova's be the things pushing the universe apart at an ever increasing speed?

And that's the irony... the very thing being studied which tells us the universe is accelerating could be the same thing causing the acceleration.

Thoughts?
