Based on a simple fact there was not time before the creation of the University (time and space can't exist one without the other). Even a kid knows that. Ah yeah, I forgot, we have a very shitty education here

How does it relate to the statement below?

What a argument; they say so, so it is so.

So, that very dense mass that did exist before big bang, didn't take any space? They say it was dense, but come on, it gotta have taken some space if all the shit around here is from it.

Time is by the way a measurement; measurement that measures and connects events. If nothing happens, you just can't measure time. Although I am quite sure there wasn't no one measuring time even after big bang, I mean for some time, and at least around here (if there is some another shit far away; like folks from older big bang, that is different matter).

Time exists as much as metre.

Who said there was a mass? Where did you learn physics, man? There was just energy which has created a mass after the explosion. The scientists blame it on Higgs boson. But with or without it, the mass can be produced from pure energy, as well as the energy can be produced from pure mass. A 9th grade of mandatory school in my country

P.S. Here is a simple formula for you that fully explains my post: m = E / c^2 (actually it was already posted in this thread). If you want, I can easily calculate the minimal amount of pure energy which was needed to create our University from nothing (no physical bodies with a mass).

You surely take somewhat uncertain things and take it as a granted. Have you no theoretical thinking? You just repeat things like a parrot.

But let me rephrase. That energy didn't take any space? Or whatever that did exist before big bang didn't take any space? You know, in volume, etc.?

I'm not a scientist, so I accept the knowledge "as is". I think that Albert Einstein and Stephen Hawking are much smarter than me so I don't question their conclusions. The E=m/c^2 works just perfect, but I will accept any better formula if it will be invented.

Depends on what type of energy you are talking about. Kinetic? Potential? Gravitational? Internal? The energy of explosion? Dark energy?

LOL ))) I gave you a formula above. Don't you agree with it?

Your superior Russian school books don't define it? You are the one who was talking about energy, so pick the one you meant.

It's not mine. It's the most famous in the World formula created by Einstein Man, it's a mandatory school material and you "have no experience to evaluate it?" Is it a joke or you really live in a cave?

I have no experience evaluating that neither. Besides, you wrote it differently or wrong.

What is mandatory school material? Evaluating the mathematical presentation or the formula itself? We didn't evaluate that much about Einstein's work. So, how it worked? Did you prove it right?

I will help you my Finnish friend. So here we go:

m = E / c^2 is the formula invented by Einstein and every kid here knows it. Let me explain it to you in the concept of the Big Bang Theory. We take pure energy (E in Joules) which has no mass ("no", means absolutely no), divide it by the light speed (c in meters per second) multiplied by itself and... get the mass outcome (m in kilograms) produced during the explosion.

Means that every citizen must learn it in the school. If a kid doesn't visit school, he will be taken out of family and will be forced (literally forced) to visit school in orphanage. The mandatory minimum in Russia is a 9 grade school and Einstein's theory of relativity is included into that education program. You may stay in school for more 2 years and then go to the university, but 9 grades is "a must". I feel a bit strange when explaining the basics of our education to such a serious expert of Russia like you.

See my explanation above.

Yes, his formula has been proven many times. For example, the nuclear bomb won't exist if it didn't work.

It's not something you have to learn (I didn't "learn" it). It's just a theory you maybe familiar with. Anyways, what it has to do with your "math as shown that an entire galaxy can be colonized in a few 100 million yeas" statement? Go ahead and show your "math" then. Will be very interesting to discuss

That equation looks a tad different in wikipedia and in other sources.

I didn't know that you blew out nukes in school. Besides "the nuclear bomb won't exist if it didn't work."- sounds a tad silly. Usually the equation is tested, not the other way around. You know; we observe things and make equations to model those things; not making some shit up and say: "my equation makes this and that possible".

have at it.


To arrive at their conclusion Dr Hair and Mr Hedman assumed that outer space is dotted with solar systems, about five light years apart. They then asked how quickly a single civilisation armed with the requisite technology would spread its tentacles, depending on the degree of colonising zeal, expressed as the probability that intelligent beings decide to hop from one planet to the next in 1,000 years (500 years for the trip, at a modest one-tenth of the speed of light, and another 500 years to prepare for the next hop).

All these numbers are necessarily moot. If the vast majority of planets is not suitable, for instance, the average distance for a successful expedition might be much more than five light years. And advanced beings might not need five Earth centuries to get up to speed before they redeploy. However, Dr Hair and Mr Hedman can tweak their probabilities to reflect a range of possible conditions. Using what they believe to be conservative assumptions (as low as one chance in four of embarking on a colonising mission in 1,000 years), they calculated that any galactic empire would have spread outwards from its home planet at about 0.25% of the speed of light. The result is that after 50m years it would extend over 130,000 light years, with zealous colonisers moving in a relatively uniform cloud and more reticent ones protruding from a central blob. Since the Milky Way is estimated to be 100,000-120,000 light years across, outposts would be sprinkled throughout the galaxy, even if the home planet were, like Earth, located on the periphery.

Crucially, even in slow-expansion scenario, the protrusions eventually coalesce. After 250,000 years, which the model has so far had the time to simulate, the biggest gaps are no larger than 30 light years across. Dr Hair thinks they should grow no bigger as his virtual colonisation progresses. That is easily small enough for man's first sufficiently powerful radio transmissions (in the early 20th century) to have been detected and for a reply to have reached Earth (which has been actively listening out for such messages since the 1960s). And though 50m years may sound a lot, if intelligent life did evolve more than once, it could easily have done so billions of years before this happened on Earth. All this suggests, Dr Hair and Mr Hedman fear, that humans really do have the Milky Way to themselves. Either that or the neighbours are a particularly timid bunch.

In the context of a homogeneous universe, we note that the appearance of aggressively expanding advanced life is geometrically similar to the process of nucleation and bubble growth in a first-order cosmological phase transition. We exploit this similarity to describe the dynamics of life saturating the universe on a cosmic scale, adapting the phase transition model to incorporate probability distributions of expansion and resource consumption strategies. Through a series of numerical solutions covering several orders of magnitude in the input assumption parameters, the resulting cosmological model is used to address basic questions related to the intergalactic spreading of life, dealing with issues such as timescales, observability, competition between strategies, and first-mover advantage. Finally, we examine physical effects on the universe itself, such as reheating and the backreaction on the evolution of the scale factor, if such life is able to control and convert a significant fraction of the available pressureless matter into radiation. We conclude that the existence of life, if certain advanced technologies are practical, could have a significant influence on the future large-scale evolution of the universe

[1411.4359] Homogeneous cosmology with aggressively expanding civilizations


Olson set out to test the ambitious idea using a mathematical model. Not only does he show that intelligent life can theoretically come to fill the vast void of space in a fraction of the universe?s lifetime, but universe spanning civilizations may influence the evolution of the cosmos itself?a profound and entirely novel suggestion.

fyi, i'm not a rookie at this gfy shit.

just a punk

It's the same one (laterally: absolutely the same formula) - just believe me. What's wrong with you, man? Yet another victim of Finnish education?

*facepalm smile here*. Are you really that dumb or just kidding on me (I'm still can't believe it's for real)? Einstein said it clear: E = m/c^2 - the energy of explosive will be equal to the mass (Google for "critical mass" in case of nuclear reaction) multiplied by the speed of light in square. I can't believe you didn't learn it in the school... And you were talking something about education level here and there? OMFG

Abstract

If even a very small fraction of the hundred billion stars in the galaxy are home to technological civilizations which colonize over interstellar distances, the entire galaxy could be completely colonized in a few million years. The absence of such extraterrestrial civilizations visiting Earth is the Fermi paradox.

A model for interstellar colonization is proposed using the assumption that there is a maximum distance over which direct interstellar colonization is feasable. Due to the time lag involved in interstellar communications, it is assumed that an interstellar colony will rapidly develop a culture independent of the civilization that originally settled it.

Any given colony will have a probability P of developing a colonizing civilization, and a probability (1-P) that it will develop a non-colonizing civilization. These assumptions lead to the colonization of the galaxy occuring as a percolation problem. In a percolation problem, there will be a critical value of the percolation probability, Pc. For P<Pc, colonization will always terminate after a finite number of colonies. Growth will occur in "clusters," with the outside of each cluster consisting of non-colonizing civilizations. For P>Pc, small uncolonized voids will exist, bounded by non-colonizing civilizations. When P is on the order of Pc, arbitrarily large filled regions exist, and also arbitrarily large empty regions.

I haven't asked you for any abstractions. I've just asked you to show me the math. I'm not aka123 and I can read/evaluate formulas(I don't need the explanations etc). So please just go ahead and shoot it here.

Maybe the same formula, but it is first time I see it written that way.

You said something about proving that equation in school. So did you make nuke tests to prove it or not? It doesn't work the other way around, as I already said.

By the way, I haven't said anything about Russian education. Surely you have superior school system. You are so smart people-> knowledge increases pain->thus you drink so much to relieve all that pain. It makes sense.

they're not MY calculations, i stated THE math shows that the galaxy can be colonized in x million years, and also supplied several mathematicians work on the subject, you can't comprehend that, I get it.

you can talk about the subject or make it about me. you choose to make it about me, I'm trying to keep to the topic.

if you want to keep to the topic too, then read the shit I posted and comment on the results they reveal and don't act like a dick about where I learned math all while you act like you have some sort of superior math comprehension.

Not a problem, please post math calculations performed by others. I'm really excited to look at them.

Fermi based his paradox on assumptions. First he assumes Earth is typical. Next he assumes interstellar travel is possible/cost effect. And he assumes there would be reason to colonize/explore everything and that it happened in the past 200,000 during human existence. Last he assumes millions of years is short time frame for an advanced species to survive and remain advanced.


------------------------

I don't think humans are typical. I think there was spark required to make life then a separate spark to make human life. Maybe we are the only lifeforms that can travel to space. Maybe others came here and brought dinosaurs home as pets. Maybe their stealth is so advanced they're undetectable.

We just learned to fly about 50 or 60 years before we left the atmosphere. But, for at least 200,000 years before that we humans, the most advanced of all species (in our own minds) didn't know much about flight or space flight. That doesn't mean intelligent advanced life didn't exist on Earth. We just hadn't figured out how to fly yet. Now we've known how to for about 0.1% of the estimated time of our existence.
