Not sure, is there actually a cycle in the universe (don't know what the latest theory is).? I suppose if a body in space becomes stardust eventually, so will the whole earth. So either way you end up as stardust.
All the planets and stars that you see in the sky (and earth) where made from spacedust. So yes you would be part of the cycle of the universe, possibly even creating new life :)
Who knows, perhaps we were created from some dead aliens shot into space.
