We call this the speed of light. pmoreira10 https://padlet.com/pmoreira10/n7lnfkalc4i67a7s/wish/2025646842 2022-02-02 15:41:16 UTC https://padlet.com/pmoreira10/n7lnfkalc4i67a7s/wish/2025646842 This energy is the fastest thing in the universe. pmoreira10 https://padlet.com/pmoreira10/n7lnfkalc4i67a7s/wish/2025646843 2022-02-02 15:41:16 UTC https://padlet.com/pmoreira10/n7lnfkalc4i67a7s/wish/2025646843 Energy that travels at high speeds through space in wavelike patterns. pmoreira10 https://padlet.com/pmoreira10/n7lnfkalc4i67a7s/wish/2025646844 2022-02-02 15:41:16 UTC https://padlet.com/pmoreira10/n7lnfkalc4i67a7s/wish/2025646844 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/n7lnfkalc4i67a7s/wish/2025646845 2022-02-02 15:41:16 UTC https://padlet.com/pmoreira10/n7lnfkalc4i67a7s/wish/2025646845 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/n7lnfkalc4i67a7s/wish/2025646846 2022-02-02 15:41:16 UTC https://padlet.com/pmoreira10/n7lnfkalc4i67a7s/wish/2025646846 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/n7lnfkalc4i67a7s/wish/2025646847 2022-02-02 15:41:16 UTC https://padlet.com/pmoreira10/n7lnfkalc4i67a7s/wish/2025646847 The universe continues to expand to this day. pmoreira10 https://padlet.com/pmoreira10/n7lnfkalc4i67a7s/wish/2025646849 2022-02-02 15:41:16 UTC https://padlet.com/pmoreira10/n7lnfkalc4i67a7s/wish/2025646849 Says that the universe expanded rapidly at first. pmoreira10 https://padlet.com/pmoreira10/n7lnfkalc4i67a7s/wish/2025646851 2022-02-02 15:41:16 UTC https://padlet.com/pmoreira10/n7lnfkalc4i67a7s/wish/2025646851 Says that the universe began as a very dense, hot, single point in space. pmoreira10 https://padlet.com/pmoreira10/n7lnfkalc4i67a7s/wish/2025646852 2022-02-02 15:41:16 UTC https://padlet.com/pmoreira10/n7lnfkalc4i67a7s/wish/2025646852 Most widely accepted theory to explain the origin of the universe. pmoreira10 https://padlet.com/pmoreira10/n7lnfkalc4i67a7s/wish/2025646853 2022-02-02 15:41:16 UTC https://padlet.com/pmoreira10/n7lnfkalc4i67a7s/wish/2025646853 REMOTE SENSING INSTRUMENTS pmoreira10 https://padlet.com/pmoreira10/n7lnfkalc4i67a7s/wish/2025646854 2022-02-02 15:41:16 UTC https://padlet.com/pmoreira10/n7lnfkalc4i67a7s/wish/2025646854 ELECTROMAGNETIC RADIATION pmoreira10 https://padlet.com/pmoreira10/n7lnfkalc4i67a7s/wish/2025646856 2022-02-02 15:41:16 UTC https://padlet.com/pmoreira10/n7lnfkalc4i67a7s/wish/2025646856 REDSHIFT pmoreira10 https://padlet.com/pmoreira10/n7lnfkalc4i67a7s/wish/2025646858 2022-02-02 15:41:16 UTC https://padlet.com/pmoreira10/n7lnfkalc4i67a7s/wish/2025646858 THE BIG BANG THEORY pmoreira10 https://padlet.com/pmoreira10/n7lnfkalc4i67a7s/wish/2025646859 2022-02-02 15:41:16 UTC https://padlet.com/pmoreira10/n7lnfkalc4i67a7s/wish/2025646859 Essential instruments for studying far reaches of the universe. pmoreira10 https://padlet.com/pmoreira10/n7lnfkalc4i67a7s/wish/2025646861 2022-02-02 15:41:16 UTC https://padlet.com/pmoreira10/n7lnfkalc4i67a7s/wish/2025646861
