The fact that people her are even attempting to compare Sagan, an planetary biologist, to NDT, an Astrophysicist, goes to show just how little you know about either man. Sure, they both have switched to "public educators" in the latter halves of their careers, but to compare their "contributions" is moot.
Sounds like most deformed-skull mouthbreathers ITT are only vaguely aware of who NDT is, likely learning about him through pop-culture osmosis and reading screenshots of tweets. NDT is a lauded researcher and has left a lasting impact on the field of Astrophysics.
His published articles written before many of you were born have contributed more to science than the sum of all you'll contribute to anything in your entire lives. You fucks minimizing his achievements clearly haven't even done a tiny bit of your own research, or you'd know how fucking stupid you sound. Read of a couple of his published works and come back here with how small of a percentage of it you understand.

He is a genius Astrophysicist, trusted advisor, business-minded, charming and articulate motherfucker, and he DEFINITELY gets more pussy than you incels ever will.
