Final answer:
It is true that the scientific views on the universe in the 1920s inspired modernist artists to experiment with new techniques, reflecting the era's spirit of innovation and change.
Step-by-step explanation:
The statement is true: The ideas of scientists about the nature of the universe inspired modernist artists to try new techniques during the 1920s. This was a time when artists were significantly affected by industrialization, social, and cultural changes, and sought to create art that mirrored the modernity and innovation encompassing their lives. The embrace of new ideas and techniques by these artists was a rebellion against the conservative norms of academic art. Modernity, innovation, and the drive for change fueled artists to participate in the creation of a new world, as exemplified by movements like Cubism and Futurism which reflected themes of simultaneity and speed, and Dadaism which expanded the boundaries of art to include non-traditional materials and mediums.
