the theory undergoes or sutains changes?

[ostap77]

"The theory can be assumed to have undergone no substantial changes." Would it be OK to structure the sentence like that in writing?

[Rover_KE]

Yes, that's fine, ostap.

[ostap77]

What about "to have sustained..."?

[birdeen's call]

No. You can sustain something clearly unpleasant, like a wound or loss.

[BobK]

No. You can sustain something clearly unpleasant, like a wound or loss.

The question is, whose theory are we talking about? Einstein would have talked about Newton's and Euclid's theories having to undergo/withstand/sustain change. When a passive conceals the agent, it seems to me to be a good idea to express it differently.

I don't have the context. We were supposed to translate sentences for next class. "Sustain" would have been incorrect to use in that sentence? Does "sustain" imply a negative meaning?

[Barb_D]

Yes, sustain has a negative connotation. The army sustained casualties in the conflict, the town sustained damage from the tornedo.
