How long will the universe exist?
5 billion years
What is the fine tuning argument for God’s existence?
The Fine-Tuning Argument, to be abbreviated by FTA in what follows, claims that the present Universe (including the laws that govern it and the initial conditions from which it has evolved) permits life only because these laws and conditions take a very special form, small changes in which would make life impossible.
What are the anthropic constants?
Anthropic principle, in cosmology, any consideration of the structure of the universe, the values of the constants of nature, or the laws of nature that has a bearing upon the existence of life.
Can you give some examples of the fine tuning of the universe?
Examples of such “fine-tuning” abound. Tweak the charge on an electron, for instance, or change the strength of the gravitational force or the strong nuclear force just a smidgen, and the universe would look very different, and likely be lifeless.
What’s beyond the edge of the universe?
In our own backyard, the Universe is full of stars. But go more than about 100,000 light years away, and you’ve left the Milky Way behind. Beyond that, there’s a sea of galaxies: perhaps two trillion in total contained in our observable Universe.
What’s the oldest thing in the universe?
GRB 090423 was also the oldest known object in the Universe, apart from the methuselah star. As the light from the burst took approximately 13 billion years to reach Earth.
What is fine tuning in deep learning?
Fine-tuning, in general, means making small adjustments to a process to achieve the desired output or performance. Fine-tuning deep learning involves using weights of a previous deep learning algorithm for programming another similar deep learning process.
Does our universe have a twin?
The new study suggests that the universe that came before our own universe was its identical twin. Image credit: NASA and ESA.
Is God the universe itself?
There is nothing separate or distinct from God, for God is the universe. If, on the other hand, the conception taken as the foundation of the system is that the great inclusive unity is the world itself, or the universe, God is swallowed up in that unity, which may be designated nature.”
Is mirror world possible?
And so it was refreshing to see small groups of scientists setting up relatively cheap experiments that just might give concrete evidence for a strange notion known as the mirror world. The mirror world, as postulated, would exist not in some inaccessible dimension or faraway exurb of space, but right here.
Why is our universe fine tuned for life?
Various reactions to the universe’s fine-tuning for life have been proposed: that it is a lucky coincidence which we have to accept as a primitive given; that it will be avoided by future best theories of fundamental physics; that the universe was created by some divine designer who established life-friendly conditions …
Is our universe fine tuned?
The fact that our Universe has such a perfect balance between the expansion rate and the energy density — today, yesterday, and billions of years ago — is a clue that our Universe really is finely tuned. The Universe really is finely tuned, and our existence is all the proof we need.
Did the Big Bang create space and time?
The Big Bang marks the beginning of space and time as we know them, so there was no space before the Big Bang. In order to do such an experiment, we would need to create a whole new universe that contained space but no matter, just to see if it’s possible.
How small was the universe before the Big Bang?
In the first period, the universe grew from an almost infinitely small point to nearly an octillion (that’s a 1 followed by 27 zeros) times that in size in less than a trillionth of a second. This inflation period was followed by a more gradual, but violent, period of expansion we know as the Big Bang.
Did gravity exist before the Big Bang?
Gravitational Waves Reveal the Universe Before the Big Bang: An Interview with Physicist Gabriele Veneziano. It’s not usually put like this, but the discovery of primordial gravitational waves two weeks ago has given us our first direct glimpse of a period before the big bang.
