This is deduced from the expansion of the Universe. Far-away galaxies recede (go away) from us, with such a speed, that they must have been near us about 14 billion years ago.
What makes you think it does?
The redshift of the cosmic microwave background radiation
Look up at the sky, and its second star to the right strait on till morning!
No, relative age dating cannot be used to determine the age of the universe. Relative age dating is a method used to determine the relative order of events or objects in geology or paleontology. To determine the age of the universe, scientists use various methods such as the measurement of the cosmic microwave background radiation and the analysis of the redshift of galaxies.
The CMBR did not reveal anything DIRECTLY about the age of our Universe. However, its spectrum and isotropy are almost perfectly as predicted by a Universe that began to expand about thirteen billion years ago -- a timeline given by the Hubble Constant. As such, it gives extremely strong support to that timeline.
It is more likely that we derived the age of the universe from its present size. The age depends upon the value of the Hubble Constant, which probably isn't really a constant in the strictest sense.As for the area of the universe, regarding it as a sphere is probably a mistake. The topology of the universe is different from that of the 3 dimensional objects with which we are familiar. ---- The answer is No. According to Astrophysicist David Palmer, we cannot currently determine the actual size of the Universe; but only attempt to determine the size of the "known" Universe which is that part of the Universe that we can see. It's analogous to standing in a stationary position in the middle of a dessert. We will be able to view sand all around us; but will have no idea how much more sand may lie beyond that which we can see.
At present, there is no way to determine where the "center" of the universe is, or even if the concept of "center" makes sense when applied to the universe.
The Universe has an age estimated to be about 13.8 billion years.
Take it to a Veterinarian. And they can determine the age.
The thickness of the shell (lip) increases with the age. This is how you can determine the age of the conch.
that portion of the universe that we can see in principle, given the finite age of the universe
