For base 16 the largest such prime is 3b9bf319bd51ff. Notice that it has 14 digits. 6 digits more than in base 10 (shown in the tweet). In general the number of digits in such primes increases with base. See plot below.pic.twitter.com/1fyoKfqbSi
more interesting cases are base 14 and 24. They represent the biggest jump in number of digits. Here are plot showing distribution of such primes.pic.twitter.com/lNUPXEig9h
Math people have entirely too much free time on their hands. 
It is the largest, not just the largest known. If you try adding a 1-9 at the end and non of those ar prome numbers, you know that this has to he the biggest existing.
Yes. This is easily verifiable.
But if you consider all bases (not just decimal), this may not be the largest
