Can relative age dating be used to determine the age of the universe?
Simple Answer:Relative age dating is usually in the domain of geology, archeology and paleontology. Relative age dating alone does not give the age of an object or the date of an even, just the relative ordering in time.More:The principles of relative age dating can, however, be applied to cosmology. The basic principle is that one uses characteristics of objects to identify whether one object is is older than another, and then arranging them in chronological order.Alone, relative age dating can not be used to determine the age of the universe or anything else, but with some knowledge of absolute age one can arrive at statements like, event B must have come after event A and event A is a known date, so event B must be at an earlier date.For instance, the universe must be older than the Earth. The Earth can be dated to about 4.5 billion years in age, therefore the Universe must be older than 4.5 billion Years. If, one adds to that the one knows that the light from a distant galaxy takes a 10 billion years to reach Earth, then the galaxy, and hence the Universe must be more than 10 billion years old.
How do you determine how much an object has aged since its light left?
The speed of light is absolute, so you begin there. You know the distance between the Earth and the sun (from celestial mechanics originally), so now you have a general idea of how long it takes for light from such an object to get to to your eyes. Now you've spotted an object - a star, or distant galaxy, let's say - and ask how far away it is. You compare its light to that of objects (like the sun) that you know. A little math tells you that what you're seeing happened there a billion years ago.
What helped scientist determine the age of the universe?
The redshift of the cosmic microwave background radiation
Scientists say that thr Universe started about 14 billion years ago Does this allow us to determine the size or total area of the Universe?
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.
Does the universe have an outer edgeor?
There is no evidence that the universe has an outer edge. The universe is thought to be spatially infinite, meaning it goes on forever in all directions. Our observable universe is limited by the speed of light and the age of the universe, not by a physical boundary.

Which of these is not used to determine the age of an object?
magnetometer
How do scientists use isotopes to determine the of an object?
Scientists use the relative amount of stable and unstable isotopes in an object to determine its age.

Is the inside of the universe younger than the outside?
All parts of our Universe our exactly the same age. There is no "inside" and no "outside" -- all parts of our Universe came into being at exactly the same amount, and no part is closer to an edge than another. That part of our Universe that we on our planet can see -- what we called the "visible Universe" -- does have this feature: the farther an object is from us, the farther back in time is what we are seeing. For example, if we view an object one billion light years from us, we are seeing what was occuring there one billion years ago; for an object two billion light years from us, what we are seeing occurred two billion years ago.
Computers can determine the age of an object?
Computers can determine the age of an object through techniques like radiocarbon dating or thermoluminescence dating. These methods utilize the natural decay of radioactive isotopes or the accumulation of trapped electrons in minerals to estimate the age of organic or inorganic materials. It requires specialized equipment and careful analysis of data to accurately determine the age of an object.
How far away are the farthest objects we can observe?
The farthest objects we can observe are galaxies that are around 13.8 billion light-years away. This distance is governed by the age of the universe, as light from these objects has taken the entire history of the universe to reach us.
What is the significance of the Hubble radius in understanding the expansion of the universe?
The Hubble radius is important in understanding the expansion of the universe because it represents the distance at which objects are receding from us faster than the speed of light due to the expansion of space. This boundary helps us determine the rate of expansion and the age of the universe.
How old is light and what implications does its age have on our understanding of the universe?
Light is estimated to be about 13.8 billion years old, originating from the Big Bang. Its age helps scientists determine the age and expansion of the universe, as well as the formation of galaxies and structures. Studying the age of light provides insights into the history and evolution of the cosmos.
