What is the duration of universe?

Unnickporser said:Well, I referred to duration like I said, to lifetime, not time from big bang. Anyway, in Wikipedia there is only diverse stimation from different models, but not a really response to the question anyway
Garrulo said:But this is a neccesary knowing because finite real statistics used in physics and all of sciences need to know how many times a random phenomemon will ocurr. There are people seeking through Planck units, but , I would like to know it too. What is the duration (from the start to the end), not the actual age of universe? And its dimensions?
Garrulo said:I don´t understand you , sorry, my english no good. Could you tell it about other words
Neither the size nor the expected life span of the universe is known.Garrulo said:Yes, this is my question
Garrulo said:Yes, this is my question
Garrulo, as you can see, here on the Physics Forum, some of us like to repeat answers that have already been given. ;)Drakkith said:We don't know how big the universe is. We also do not know how long it will exist for.
Mi question is not trivial. We use probability all times, but probabilities small are not possible in function of the number of experiments that can be done in the universe about the experiment we wish know if a determinate event can ocurr. For example, age of universe is around 1018 s, and universe radius is around 1018 m. An event of an experiment done in a meter length laboratory with duration of one second have a probability of 10-36 can be dischargedGarrulo said:It is said that actual quantum theories can´t measure times longer than 1018 s, and this is the reason because we measure this quantity for the universe age
HUH? Where did you hear this? Sounds like nonsense to me. Can you give me a citation?Garrulo said:It is said that actual quantum theories can´t measure times longer than 1018 s, and this is the reason because we measure this quantity for the universe age
I can't make any sense at all out of this post. Can you say it differently?Garrulo said:Mi question is not trivial.

The current estimated age of the universe is approximately 13.8 billion years old. This is based on data from the cosmic microwave background radiation and the observed expansion of the universe.
Scientists use various methods such as the cosmic microwave background radiation, the redshift of distant galaxies, and the age of the oldest stars to measure the duration of the universe. These methods all provide consistent estimates that support the age of 13.8 billion years.
No, the duration of the universe has not always been constant. In the early stages of the universe, it underwent a rapid period of expansion called inflation. After this period, the expansion has been gradually slowing down due to the force of gravity.
The answer to this question is still unknown. Scientists have observed that the universe is currently expanding, but it is uncertain if this expansion will continue indefinitely or eventually slow down and reverse. More research and data are needed to determine the fate of the universe.
It is unlikely that we will ever know the exact duration of the universe. The methods used to measure the duration of the universe have limitations and uncertainties. Additionally, the concept of time itself is a complex and elusive concept in the field of physics.
