New light on dark energy
24 June 2004
Cosmologists in the US have made the most accurate measurements ever of how dark energy varies with time -- and found that it remains perfectly constant.
If dark energy became progressively weaker, the universe would eventually tear apart in a "big rip". If it became stronger, on the other hand, the universe would collapse in on itself in a "big crunch".
