Solved in 2 steps
- What is the order of objects to form from first to last after the Big Bang nuclei,neutral Atoms, protons?The discovery of the dark energy was a surprise because astrophysicists generally assumed that the expansion would be slowing down. Select one: True FalsePlace all of the following in order from earliest to the most recent: Dark energy begins acceleration of the expansion of the universe You study for your final in astronomy Last scattering of the Cosmic Microwave Background Radiation First stars and galaxies form Big Bang Universe becomes transparent (no longer opaque) aka photon decoupling time Inflationary Epoch Formation of first complex elements (hydrogen isotopes, helium & lithium)
