Between their biases, general ignorance, and racist views they pretty
much did themselves in from all this.

They dismissed Einstein's ideas as "Jewish science" and of course he
and many other great minds left Europe for the Allies where they did a
lot of good for our side.

Thankfully for us, Hitler never fully appreciated or understood what
Wernher von Braun had with the V-2 rocket. He still thought massive
bomber strikes with his Luftwaffe would do the trick. And while they
did introduce the fighter jet into the war, it came rather late and did
not do the damage a fleet of them might otherwise had done.

And on the pure science front, when they did think about it, Nazis
supported one fringe astronomer's idea that under the Moon's crust was
a layer of ice. This was all part of some off the wall theories on how
the Universe was formed.

What made this serious was that their supporters tried to force this
idea as the main one for German university astronomy courses.
