Create a digital model of a football field. starting at the left and moving forward in time, label the
10-yard lines in years. using different colors, draw a horizontal line to mark the beginning and
end of each of the following periods and eras [note that the years have been rounded up for this activity]:

• cenozoic era (65 mya to present)
• triassic (245‒208 mya), jurassic (208‒146 mya), and cretaceous (146‒65 mya)
periods
• paleozoic era (570‒245 mya)
• proterozoic era (2,500‒570 mya)
• archean era (3,800‒2,500 mya)
• hadean era (4,600‒3,800 mya)

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.

explanation:

the supermassive black hole is in the middle of the galaxy.
