The universe is between 12 and 14 billion years old, lets assume 13 billion. A year is 365.25 days (approximately). A day is 24*60*60 seconds = 86400 seconds.
Bear in mind that a nice human life will last for about 2.5 billion seconds, whereas the universe has existed for around 432,043,200,000,000,000 seconds.
Time is a property of the Universe and has always existed. How long time has been around is an observer dependent question (thanks to time
How many picoseconds has the universe existed? Did the universe have a beginning?
Linde and Vanchurin then estimated how many different universes could have appeared as a result of this effect.
I don't know, how "eternal inflation" allows "existence of many universes".
How is it that if we were to squeeze the age of the uni. into 24 hours, humans were only created 4 seconds before midnight?

According to Frank's equation, given how many planets exist and how many years the universe has existed, there's a 1 in 10 billion trillion chance that humans are the only civilization to ever live.
That we cannot get more energy out of a system than we put in. It is my understanding that the universe
If we do, in fact, live in a multiverse, with multiple universes arising out of the Big Bang, how many are there? Andrei Linde and Vitaly Vanchurin at Stanford University have been working to calculate a number, based on quantum fluctuations in the early
As long as you admit that there is more than one conceivable way for the universe to be (and
How the Universe Began. Some of the things most evolutionists believe are true.
The second law states entropy can not be destroyed and is forever increasing. Based on this you could also state that the universe has existed for an infinite amount of time which would imply that some point along
How did the universe came into existence isnt answered, its nice math just after the moment..not
If the universe has existed forever, this would entail an actually infinite number of past events.
3. Therefore, the universe has a cause of its existence. Let us examine this argument more closely.
Two questions I shall discuss are, 'What is the probability of life existing else where in the universe?' and, 'How may life develop in the future?'
YouTube/Perimeter Institute. Johnson is looking for those bruises, but a lot depends on how fast other bubble universes sprang into existence and how many there are. If only a few other bubbles exist, they might have not hit us.
First of all, I'm not sure the universe ever had an edge (the physics guys will come in to to explain soon, and I'll get a headache, as always). Second of all, as the universe can't expand at faster than the speed of light, then it probably would...
I have always felt an extreme connectivity with the universe, and I have found the most success in my life has derived from following those patterns, and becoming more aware of them.
They have also helped cosmologists improve estimates for how much dark matter and dark energy existed in the early universe (and likely still exist
C. Because looking 15 billion light-years away means looking to a time before the universe existed.
How do you know that no state (first, last, or any in between) or part of the universe has an essence that is identical to
As the Universe expands and cools, it becomes harder and harder to make new particle-antiparticle pairs, while the existing ones will continue to annihilate away into photons, or
They point out that we now have an understanding of the history of the universe, and of the physical laws that describe how it works.
...universal histories, that exist simultaneously and represent every state of every object and which the universe has some-how already lived.41.
Many argue that all things must have a cause, and therefore, god exists as the 'first cause' of everything else.
Defining this "beyond the universe" would imply that the universe has an edge. And that's where things get tricky, because scientists aren't certain if such a drop-off exists. The answer depends on how one views the question.
Since there have been no discoveries to dispute this theory and this seems to be the most sensible theory for how everything in the universe was created, then it is
Why did everything we need in order to exist come into being? How was all of this possible without some latent outside power to orchestrate the precise
In the absence of magical unicorns the universe still exists, so all that we are really saying about unicorns is that imaginary things don't have form like we have form.
That is, Elements, are the supposed to be the most basic constituents of matter, Aristotle had
First, the universe has been evolving with time. Stars and galaxies did not always exist.
Expansion should be more at the outside area or the edge of the universe or something like that.
This is what the second law of thermodynamics deals with . Usable energy is constantly becoming less usable for doing work .
The big bang. One of the most persistently asked questions has been: How was the universe created? Many once believed that the universe had
Our universe has existed for nearly 14 billion years, and as far as most people are concerned, the universe should continue to exist for billions of
» Science Questions & Answers. » How Did the Universe Begin? - - A Simple Explanation.
To put that in perspective, if you visited each planet for a single second, it would take 585 billion
b) The highly ordered universe today could not have come from an explosion - the second law of
[ADD MORE]. The very existence of matter (baryons) requires that symmetry broke very early, at about 10-10 seconds after the Big Bang (see the note on clumpy energy).
One of the most exciting questions for mankind is whether we are alone in the universe.
Have you ever thought about exactly how the famous Stephen Hawking ponders over our universe?
Think of how the universal wavefunction ψ(r, t) might behave when r is the position of all the particles in the universe. Let's call 9:00am the time t=0, measured in seconds.
Nothing exists outside of the universe, as the universe by definition includes everything.
A Fermi Question: How Many Communicating Civilizations Exist? Represent the number of communicating ETCs in the Galaxy by the symbol N. To estimate
We believe the universe to be infinite today, which means it was infinite in its formation so this infinite singularity is the picture to have in mind for the Big Bang.
Our physics can explain most of the evolution of the Universe after the Planck time (approximately 10-43 seconds
Despite our microscopic presence in the Universe, it's pretty cool that we're here at all. Prepare to have your mind blown here
A team of scientists has reworked the famous Drake equation in order to answer the question of whether humans are the only technological species to have ever existed in the universe.
We will also come to understand how more advanced human beings who exist throughout the Universe view us.
...including several Nobel laureates, that the universe may actually exist in higher-dimensional space.
That is why it has been so hard to squeeze the hydrogen gas for more than about one second.

The second, and more critical, wrong assumption is that the observed red shifts are only due to the Doppler effect and presumably show that the stars with red shifts are receding.
Firstly, if any life else than us exist in the universe we would have the slightest indication of it by now.
You can imgaine any way how non physical reality exists, but it is just a silly idea in a silly head that has nothing to do with reality.
