I Like 'the Simpsons' Quite A Lot.

The Idea That There Could Be Other Universes Out There Is Really One That Stretches The Mind In A Great Way.

If String Theory Is Right, The Microscopic Fabric Of Our Universe Is A Richly Intertwined Multidimensional Labyrinth Within Which The Strings Of The Universe Endlessly Twist And Vibrate, Rhythmically Beating Out The Laws Of The Cosmos.

But If You Think About A Practical Implication Of Enriching Your Life And Giving You A Sense Of Being Part Of A Larger Cosmos And Possibly Being Able To Use This [gravitational Waves] As A Tool In The Future Maybe To Listen Not Just To Black Holes Colliding, But Maybe Listen To The Big Bang Itself, Those Kind Of Applications May Happen In The Not Too Distant Future.

Time Allows Change To Take Place And The Very Evolution Of The Universe Is What Requires Some Conception Of Time. Mathematically Can We Write Down A Universe That Doesn't Have Time? Sure. Do We Think That Would Be Realised In The Larger Reality That Is Out There? None Of Us Take That Possibility Seriously.

Free Will Is The Sensation Of Making A Choice. The Sensation Is Real, But The Choice Seems Illusory. Laws Of Physics Determine The Future.
