Recently the scientists have discovered shocking news; the Red Shift from distant galaxies is greater than previously measured. This can only mean one thing. Not only our universe is expanding, it is speeding up. Scientists have never predicted that. Scientists had no answer what could have caused this. They could not believe this. But data proves that universe is certainly accelerating. They made up a theory that some sort of invisible energy is working against gravity and causing our universe to accelerate. They call it the DARK ENERGY.
