hubble constant การใช้

• Schmidt's PhD thesis was supervised by Robert Kirshner and used Hubble Constant.
• There wasn't a miscalculation of the Hubble constant, the two astronomers concluded.
• "He's winning the Hubble constant debate, but he's taking no pleasure in it,"
• The debate over the Hubble constant has divided astronomers into two main camps.
• :: In different units, the Hubble constant is about 0.00007 Myr  " 1.
• He has raised at least two procedural objections to the high Hubble Constant values.
• The number of the Hubble constant, they concluded, is 70, plus or minus 7.
• But most observers didn't consider his estimate of the Hubble constant too far from hers.
• Knowing the value of the Hubble constant helps cosmologists estimate the age of the universe.
• The subscript'0'indicates the value of the Hubble constant today.
• Ditto for " quantization of the redshift " or " explanation of the Hubble constant ".
• The discovery astonished astronomers, but it helped clarify the age problem that arose with the Hubble constant.
• Sandage determined the first reasonably accurate values for the Hubble constant and also discovered the first quasar.
• He determined the first reasonably accurate values for the Hubble constant and the age of the universe.
• Also, the Hubble constant was measured to be 67.80 ?0.77 ( km / s ) / Mpc.
• The measured velocity of galaxies moving apart with the expansion of space-time is expressed as the Hubble constant.
• Freedman's adversary in the Hubble constant wars has been Allan R . Sandage, also at the Carnegie Observatories.
• By contrast, a high estimate of the Hubble constant implies a rapid expansion and a relatively young universe.
• Thus, with observed time delays and constrained mass model, the cosmological constant like Hubble constant can be inferred.
• Estimates of the expansion rate, also known as the Hubble constant, are fundamental to all theories of cosmic evolution.
