For Most Of Human History, We Could

I Vowed To Myself That When I Grew Up And Became A Theoretical Physicist, In Addition To Doing Research, I Would Write Books That I Would Have Liked To Have Read As A Child. So Whenever I Write, I Imagine Myself, As A Youth, Reading My Books, Being Thrilled By The Incredible Advances Being Made In Physics And Science.

Chances Are, The Aliens Will Not Want To Land On Our Backyard, Or Even The White House Lawn, With Their Flying Saucers. They May Have Tiny, Robotic Self-replicating Probes Which Can Reach Near Light Speed And Can Proliferate Around The Galaxy. So Instead Of The Enterprise And Huge Star Ships, The Aliens Might Actually Send Tiny Probes To Explore The Universe. One Might Land On Our Lawn And We Won't Even Know.

It's Very Dangerous To Put Astronauts On A Moon Base Where There's Radiation, Solar Flares And Micro Meteorites. It'd Be Much Better To Put Robots On The Moon And Have Them Mentally Connected To Astronauts On The Earth.

Some People Are A Little Bit Afraid About The Future Because They See All These Gadgets And Gizmos Coming Down The Pike And They Think They're Too Old To Learn All This New Stuff. But Eventually They Begin To Realize, 'hey, Some Of This Stuff Is Useful.'

The Most Likely Possibility, Favored By Current Data, Is That The Universe Will Die In Ice, Not Fire. However, Personally I Believe That Trillions Of Years From Now, We (if We Are Still Around) Will Have The Technology To Leave The Universe, Perhaps In An Interdimensional Life Boat, And Move To A Warmer Universe.
