Which is an idea that einstein introduced in his theories of relativity? a.) space is made up of three dimensions. b.) space and time are separate and distinct entities. c.) space-time bends due to the masses in the universe. d.) gravity is caused by a force of attraction between two masses.

Space-time bends due to the masses in the universe.

Choice C is correct

Explanation:

Space-time bends due to the masses in the universe is an idea that Einstein introduced in his theories of relativity.

If a body of any mass is placed down anywhere in the Universe the space around it will curve in response.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.

a and c are the answeres
