My 720T battery has extremely low life. It basically has to be powered all the time. Perhaps I need to change the battery. What is the battery called for 720T?Is it the same as for 720?

This is such a contentious question. Humankind does seem to have a basic need to believe in a higher power.

At one extreme we have those who believe that the Cosmos is a random accident, including us. At the other, a Supreme Creator.

Certainly it is the case that our kind of life could not exist, if just a few vitally important basic physical values were to change just a bit.

On the other hand, if it all was not so perfect for us, then we would not even be here to look at the Cosmos and wonder. Does the Cosmos care either way?

Not me but I am assuming you have googled the problem also.
