NASA Gives Up on LISA

This has been feared for a while in that community. There's quite a bit of animosity towards the JWST for soaking up NASA's budget in recent history, and JWST is trying to do some serious damage control because they're too far along and too big to fail. I saw John Mather (Nobel prize winner) give a talk recently that was basically "Look how far we are, and we're sorry for soaking up the budget."

That's too bad. Gravity waves are one of the last unknowns in science that we also know how to study. (Most other unknowns we don't know how to study.)<p>I've always wondered, we have rich foundations doing all kinds of good - do any of them try to step in and fill budgets of this sort?

A question to all the billionaires watching this thread:<p>Why would you give away money to charity while you could sponsor LISA?
