"And the earth abideth forever"-- Is it literal or figurative? (click here for original Hebrew version)
Update: Rabbi Dr. Yonah Merzbach (1900-1980) was for many years chief editor of the Encyclopedia Talmudit and former rabbi of Darmstadt, Germany and a faculty member of Yeshivas Kol Torah. [*]
It is incumbent upon sages who write in periodicals to be careful in their words so that they not become a stumbling block. And therefore I wrote these words.
 Rav Emden actually ended up opposing Copernicus although some things that he wrote seemed to indicate possible agreement.
 Literally, חרדים, and I originally translated as Charedim. This left the a possibly faulty impression of who was being referred to (per commenter "Norm").
Update: Here is the full quotation regarding the "faster-than-light" argument:
There are other arguments used [against geocentrism], and they seem like good ones but in fact they don’t work out in real life. For example, the most obvious one is that distant stars are light years away. If they circle us once per day, they must move faster than light, which is impossible! This is true even for Neptune; at its distance it would have to move at just faster than light to make one circle every 24 hours.
I thought about this, and wound up asking my friend the cosmologist and fellow Hive Overmind blogger Sean Carroll. He confirmed my thinking: relativity says the math has to work out if you change a frame of reference, so if you do the detailed relativistic equations to look at the motion of distant objects, it still works. Things actually can move faster than light relative to the coordinate system, it’s just that things cannot move past each other with a relative speed greater than light. In the weird geocentric frame where the Universe revolves around the Earth, that is self-consistent.
In other words, the Neptune-moving-too-quickly argument sounds good, but in reality it doesn’t work, and we shouldn’t use it.
