Emails From Heaven
Robert Kuhn interviews the ever ebullient and entertaining physicist and futurist Michio Kaku on the always pressing question of whether life – and the Universe itself – has any meaning.
Kaku ultimately suggests that meaning for homo sapiens comes from what we do with our lives, and how we value our activities.
Kaku quotes Freud’s answer to this question, namely that life gains meaning through work and through love. He speaks of more conservative scientists who say that the purpose of life – to quote Saint Ignatius – is to give greater glory to God (ad majorem dei gloriam).
Putting the two together, it seems to me that performing work that makes a difference in society, as well as helping our fellow human beings in a Christ like way, is doing God’s work.
I once asked my brother – who was teaching Sunday School, and didn’t know how to pop the hood of his car – where heaven was. He knew he was in for a sparring, but his answer was nevertheless brilliant:
Heaven is where your heart is.
Whither the Martian Atmosphere?
The principal scientific team – out of the University of Colorado at Boulder – has now just reported what it thinks happened to Mars’ atmosphere.
Because Mars does not have a significant magnetic field, it cannot “shield itself” from the solar wind and that wind’s own magnetic field.
When the solar wind’s charged particles hit the Martian atmosphere, at speeds up to 1.8 million miles per hour, molecules in the Martian atmosphere become ionized, and can be transported into space by the solar wind’s own magnetic field. This process is called sputtering.

MS – An Update
In December 2016, I wrote about a new therapy for primary progressive multiple sclerosis called Ocremizulab. Well, according the Chicago Tribune, the FDA just approved it for distribution. That was fast!
