We call this the speed of light. pmoreira10 https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643676 2022-02-02 15:40:01 UTC https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643676 This energy is the fastest thing in the universe. pmoreira10 https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643679 2022-02-02 15:40:01 UTC https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643679 Energy that travels at high speeds through space in wavelike patterns. pmoreira10 https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643681 2022-02-02 15:40:01 UTC https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643681 Scientists can use this to calculate the rate of the expansion of the universe and to work backward to determine when the expansion began. pmoreira10 https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643682 2022-02-02 15:40:01 UTC https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643682 It occurs as objects move farther away from a source and the light shifts toward the red end of the electromagnetic spectrum. pmoreira10 https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643684 2022-02-02 15:40:01 UTC https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643684 Scientists can estimate the age of the universe by observing the universe’s oldest stars and the intensity of this phenomenon. pmoreira10 https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643686 2022-02-02 15:40:01 UTC https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643686 The universe continues to expand to this day. pmoreira10 https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643688 2022-02-02 15:40:01 UTC https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643688 Says that the universe expanded rapidly at first. pmoreira10 https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643690 2022-02-02 15:40:01 UTC https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643690 Says that the universe began as a very dense, hot, single point in space. pmoreira10 https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643692 2022-02-02 15:40:01 UTC https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643692 Most widely accepted theory to explain the origin of the universe. pmoreira10 https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643693 2022-02-02 15:40:01 UTC https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643693 REMOTE SENSING INSTRUMENTS pmoreira10 https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643695 2022-02-02 15:40:01 UTC https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643695 ELECTROMAGNETIC RADIATION pmoreira10 https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643696 2022-02-02 15:40:01 UTC https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643696 REDSHIFT pmoreira10 https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643698 2022-02-02 15:40:01 UTC https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643698 THE BIG BANG THEORY pmoreira10 https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643701 2022-02-02 15:40:01 UTC https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643701 Essential instruments for studying far reaches of the universe. pmoreira10 https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643703 2022-02-02 15:40:01 UTC https://padlet.com/pmoreira10/dm182rptqwc4s6h9/wish/2025643703
