Question

which piece of evidence best supports the claim that much of our knowledge about the universe comes from electromagnetic observations? a telescopes reveal information about celestial objects without physically traveling to them. b the human eye can see every type of wavelength the same. c observations from earth give us all the information we need about the universe. d astronauts have visited stars and returned samples.

Explanation:

Telescopes use electromagnetic - radiation to observe celestial objects. They allow us to gather information about the universe without physically traveling to distant objects. The human eye can't see all wavelengths. Observations from Earth don't give all - universe information. Astronauts haven't visited stars and returned samples as stars are extremely far away.

Answer:

A. Telescopes reveal information about celestial objects without physically traveling to them.
