And that's why I believe there is intelligent life in the universe besides us.

Also, Total Perspective Vortex?

[–]seffers 63 points64 points ago

sorry, this has been archived and can no longer be voted on

The possibility of there not being other intelligent life seems pretty slim when looking at the scale, doesn't it? But I doubt humans will ever make contact with them before we're brought to extinction one way or another. It's a pretty long trip to go exploring...

Think about it from the perspective of a caveman reaching the shore of the ocean. It would take thousands of years for humans to set sail and reach new lands. I think that we are in the same phase now except the atmosphere is the shore and we can only dream of what lies beyond it.

Trying to find life in the Universe, is like taking a cup, dipping it into the ocean, and expecting to find a fish.

It's a really long journey before we set to explore the Cosmo's, but when that day comes it will be magnificent.

I also believe that this is an inevitable, logical step in our evolution. The only question is, will we destroy ourselves before we are able to reach it.

The chances of us destroying our selves are much greater than us traveling the Cosmo's at this moment.

But we eventually invented technology to make fish-finding tools. We've just started to identify and analyze rocky planets, which might be compared to a rudimentary fishing-spear equivalent of ET-finding tools.

If humans can avoid outright extinction long enough, us or our descendants will probably find something.

[–]HeezyB 0 points1 point ago

sorry, this has been archived and can no longer be voted on

Identifying rocky planets, and analyzing them is no where near the step to travel the Cosmo's and identify if there is life outside of our solar system. The Universe is so vast, that saying making a fishing-spear in the ocean is like saying creating a spaceship which travels faster than light, because even with the speed of light we will have trouble finding life that is nearby.

[–]RobbStark 0 points1 point ago

sorry, this has been archived and can no longer be voted on

Conceivably, we won't need to travel everywhere and investigate every single possible rock for life. Just like fishing, we might invent the technology to predict where life would arise or settle, or to detect it outright from afar as we can with sonar and other fish-finding tools.

It's a big universe, true, but our robot descendents will have an equally big amount of time to look...

There is a difference between exploring the oceans and exploring space that is pretty significant. To cross an ocean, it may take you a month or two. To get to our nearest neighbor star at the speeds we can reach today, it may take 19000 years.

[–]tewas 32 points33 points ago

sorry, this has been archived and can no longer be voted on

To be honest, for caveman reaching other side of the ocean at their speeds, could have taken a little more than month or two. We improved technology that allowed us to cross that ocean in a month. Our space travel is nothing more than simple paddle raft in the vast ocean of vacuum. Give some time, we might figure something like a sail boat

[–]northendtrooper 23 points24 points ago

To the caveman they were limited to technology. To our modern society we are limited to physics. Until we have the technology to surpass that ceiling we will forever be that CAVEMAN looking to cross the ocean.

[–]theshame 5 points6 points ago

sorry, this has been archived and can no longer be voted on

The point of the aforementioned technology is to overcome perceived physical limitations. I highly doubt FTL travel is possible, but there's a chance that we just haven't discovered/invented the means to achieve it.

[–]rage103 2 points3 points ago

It's easy, you don't go faster than light, you simply increase the speed at which light travels!

[–]JewboiTellem 3 points4 points ago

sorry, this has been archived and can no longer be voted on

They aren't perceived physical limitations, they are actual physical limitations! Even traveling a significant fraction of the speed of light would make any space debris capable of destroying the vessel with ease due to the energies at play. It's just simply not feasible.

[–]goldegl 9 points10 points ago

It's simply not feasible given our current understanding of the universe. I am not even going to begin to pretend we know as much as we think we do.

How many times has it been claimed "that's it, there is nothing more to know" in the history of man? Many, many times. How many times has it been proven that there is more to know? Many, many times. What tickles me is how damn sure people are that they know everything there is, people will look back on them and laugh at their childish ignorance.

[–]JewboiTellem -2 points-1 points ago

The laws of physics that are limiting us (GR) have been proved to be true. I don't get why people are so dubious of the laws. THEY ARE LAWS OF PHYSICS FOR A REASON! It's like saying that we could somehow maybe make a machine that could output more energy than it takes in because we don't know everything about engineering and physics.

I think you missed the point of the analogy.

As cavemen we didn't have the technology to set sail, but a number of years down the line we figured it out and it became somewhat trivial.

Right now we're cavemen looking into the ocean of space, we'll figure it out some day.. assuming we don't all destroy ourselves first.

[–][deleted] 2 points3 points ago

sorry, this has been archived and can no longer be voted on

I didn't miss the point. I'm a realist. We can't get our spaceships anywhere close to the speed of light. Knowing what we know about the universe, we can't necessarily plan for the ability to overcome the light speed barrier. We can't bet on stargate-like technology when we have no evidence that anything can go faster than the speed of light. If the travel time to another star is longer than the lifespan of a human, it presents another set of challenges, which we may be able to overcome with cryogenics. In any case, none of us will be alive to even see the planning stages of any such mission.

There is a limit on how fast you can go in space though -- the speed of light. And it's not something we'll overcome someday, it is literally impossible.

The possibility of FTL technology exists, we cannot conceive of it yet. There are all sorts of historical analogies that show we are capable. I know there are some fundamental physical constraints that may very well prove it impossible, but the fact is, there are solutions to GR that show it can be done in some form.

Even if it is possible (and that is likely an exceedingly small possibility), it won't happen any time soon.

[–]JewboiTellem -5 points-4 points ago*

sorry, this has been archived and can no longer be voted on

You can't travel FTL is you have mass. Ever. Even if you don't have mass, you still can't! Please, talk to someone who knows anything about physics, like a physicist...the term FTL doesn't even really make sense.

Faster than light travel will never ever ever ever ever ever ever ever ever ever be possible to achieve. Even near-light-speeds will probably never happen!

Edit: Just because you're pissed that there are obvious limitations on how fast/far we will be able to travel doesn't mean you have to get all bitter about it.

[–]salbris 4 points5 points ago*

sorry, this has been archived and can no longer be voted on

Actually, FTL doesn't mean you actually "travelling" faster than light. You need to use methods that get around time dilation. The problem is that with traditional propulsion you are constantly obeying the speed of light limit, so the faster you go the more your mass increases so the less your acceleration will change your velocity.

Anyways, if you can get around that. Say, by warping space-time instead of moving traditionally, then you are no longer held down by the speed of light limit. Because if you shrink the space in front of you and lengthen it behind you and say your travelling at 0.5c your actually going much much faster, but without the limit because you're actual velocity is only 0.5c

Edit: Some pretty poor english has been corrected.

No one can sit here today and tell you what 1,000 years in human future will look like. Our perception and understanding of physics continues to change. We discover new things. We aren't at the pinnacle of scientific existence TODAY and are no where close. So really, we are limited by our current knowledge and any assumptions made on the vast future of our species and potential interstellar travel are just baseless using current data.

No one is talking about jumping on a spaceship in 2020 and warping out to Alpha Centauri or anything.

Plus there's the time-scale to think about.

I think the chance of other intelligent life (other than us, I mean) ever existing is probably really high - but how long do these civilizations last on a galactic time-scale? Mostly not more than the blink of an eye I'd guess.

Us looking for Aliens in the universe might be compared to a mosquito that lived in India in 500BC, and an ant that lives in Brazil in 2011. They both existed, but they'll never be aware of each other (bad analogy really but I hope it helps to explain what I'm trying to say).

[–]Kryptus 1 point2 points ago

sorry, this has been archived and can no longer be voted on

I agree and understand what you are saying. Civilizations do not last forever. Extinction events are common and most likely happen to most any planet for numerous reasons. Odds of life existing on another planet is one thing, but the odds of two civilizations on different plants, living long enough to find each other is an entirely different thing.

[–]Kryptus 1 point2 points ago

I would predict that when we are able to reach distant planets, we will just be doing lots of archaeology. We will find evidence of previous life, but no intact civilization.

Kepler has already proven what some knew / expected all along. We know of 500+ extrasolar planets around other stars now. We needed scientifc proof. That is the microsoptic tip of the iceberg. In ten to twenty years that number will increase by a factor of ten. My guess anways. I think we're reaching a new period of new scientific enlightenment. Two or three generations from now kids will grow up knowing we live in just one of the untold numbers of goldilock planets. I hope they continue looking towards the heavens and pulling back curtain on the universe. What lurks unseen out there has the greatest potential to unite the planet and allow humans to transcend our petty differences in ways previously not possible. Imagine humanity uniting against a doomsday asteroid or the revelation of discovering an artificial object somewhere just beyond our technological reach. How better would our world would be.

But also consider how many species have ever existed on Earth and how many of them can be classified as intelligent life...

[–]BeExcellent 0 points1 point ago

sorry, this has been archived and can no longer be voted on

Well I'm in physics and I've developed a sense of intuition regarding larger numbers. I agree with you that there is no inherent sense of large numbers, but my claim was that one can train themselves to recognize the scale of larger numbers. While I didn't know exactly how long 1B minutes was in terms of amounts of time on a human scale, I did recognize it was on the order of thousands of years due to my training and familiarity with large numbers and orders of magnitude. I agree if you asked the average person how long that was, they would probably guess 1B minutes was contained within a lifetime. All it takes is training.

[–]Jonthrei -1 points0 points ago*

sorry, this has been archived and can no longer be voted on

eh, fair enough, with familiarity, you can get a very solid "educated guess" - but i know for a fact that the human brain just can't handle huge numbers in the same way it can't handle physical dimensions past three. you can certainly use tricks to help visualize - but its pretty much impossible to imagine one billion and picture it accurately, in much the same way its pretty much impossible to visualize a hypercube past n=3 without cheating and representing it in fewer dimensions, or focusing on it from one angle only.

a person who works with huge numbers on a daily basis, or with mluti-dimensional shapes, would certainly be much better at doing these things than an intelligent layman. but much like trying to hold a string of numbers in your head, barring mnemonics, there is a very, very hard limit with minimal variation between individuals.

its quite a clear statement. picture the number seven. clear representation. picture the number 49. same deal. picture the number 1,764,445,926. if anything, its just a mass, and its nowhere near accurate. this is because our brains are simply not wired for accurately interpreting numbers beyond what we would encounter in our day to day lives as hunter gatherers.

The pattern shown here keeps on going if you take into account neighboring "universes" (which I'm sure will need to be assigned a better name down the road), and the potential for those to be organized into clusters as well. And we can go the same level of steps if not more in the opposite direction down to the sub-atomic level. The simulation that is our reality is running on one hell of a beefy machine.

When you see the cosmic web, and realize how much it looks like the neural pathways in a brain, the possibilities are exciting. Reminds me of a Mandelbrot fractal.

Just to bring things into scale. If our sun was shrunk down to a quarter of a inch. Pluto would be 100 feet away, measuring around .0007" in diameter. The earth would be 2' 6" away from the sun measuring around .0026" in diameter.

The largest known star, at this scale would be 42 feet in diameter. The nearest star to our own would be 130 miles away. Light travels .06" per second, or 1" every 16 to 17 seconds or 30 miles in a year.

I think the Milky Way representation is off. It used to be represented like this, but I'm pretty sure current astronomy has shown we live in a barred spiral galaxy.

Im not sure how old this image is exactly, but I've seen it quite a few times before, so it can't be that new.

I'm not disagreeing, but do you have a reference for the Milky Way being a barred spiral galaxy? I haven't seen that before.

Edit: Don't worry, I found it.

I've always been a fan of scientific facts which put the world and universe into perspective. One of my favorite books growing up was "2,201 Fascinating Facts", published in 1983. Some of the interesting facts from the "Universe: Stars, Planets, Space" section:

  • If one were to capture and bottle a comet's 10,000-mile vapor trail, the amount of vapor actually present in the bottle would take up less than 1 cubic inch of space.

  • To an observer standing on Pluto, the sun would appear no brighter than Venus appears in our evening sky.

  • The Earth moves in its 585-million-mile orbit around the sun approximately eight times faster than a bullet travels.

  • When the Apollo 12 astronauts landed on the moon, the impact caused the moon's surface to vibrate for fifty-five minutes. The vibrations were picked up by laboratory instruments, leading geologists to theorize that the moon's surface is composed of many fragile layers of rocks.

No one is small.

"Recognize that the very molecules that make up your body, the atoms that construct the molecules, are traceable to the crucibles that were once the centers of high mass stars that exploded their chemically rich guts into the galaxy, enriching pristine gas clouds with the chemistry of life. So that we are all connected to each other biologically, to the earth chemically and to the rest of the universe atomically. That’s kinda cool! That makes me smile and I actually feel quite large at the end of that. It’s not that we are better than the universe, we are part of the universe. We are in the universe and the universe is in us." — Neil deGrasse Tyson

[–]Hapax_Legoman 10 points11 points ago

Neither. The observable universe is a sphere centered on whoever's doing the observing.

[–]FnuGk 0 points1 point ago

sorry, this has been archived and can no longer be voted on

the universe is mostly the absence of matter or simply just nothing. So what would be on the other side of the universe? Simply there would be nothing so in that way it is infinite though there is a radius with the big bang as center point where there stops being any matter.

[–]jasontimmur 6 points7 points ago

You're forgetting that time and space itself came from the big bang. No center.

This is the part that always gets me. What did the big bang expand into?

[–]faylan7 2 points3 points ago

sorry, this has been archived and can no longer be voted on

It didn't expand into anything. All of space was just infinitely dense. Imagine taking a sheet of graph paper where each square is 1 mm x 1 mm. Then you expand the squares so that they're 1 cm x 1 cm, and keep going until you've got several meters in between each line. You didn't gain any squares, the area between them just increased.

Now imagine your sheet of graph paper is infinitely large, and you have the big bang

[–]l34t 2 points3 points ago

sorry, this has been archived and can no longer be voted on

Contrary to the common belief, the Big Bang wasn't an explosion. And the expansion of space is not analogous to a muffin expanding in the oven. Imagine the number line from 0 to infinity. How many numbers do you have? The answer is infinity. Now multiply the number line by 2, how many numbers do you have now? Still infinity. You didn't get any more numbers by the multiplication. The interval between every number just got bigger by a factor of 2. This is essentially what the metric expansion is. Why is this happening and what is causing it? Dark matter. That's all we know. Just a name. We know absolutely nothing more than that.

[–]hearforthepuns 1 point2 points ago

sorry, this has been archived and can no longer be voted on

If it wasn't an explosion, why didn't "they" choose a more appropriate name at some point?

I find it oddly comforting that no one else knows the real answer either.

[–]l34t 2 points3 points ago

sorry, this has been archived and can no longer be voted on

Physicists have a funny way of naming stuff. Names are not always/necessarily descriptive of the function of a phenomenon. For example: black holes are not holes, neither are they black.

You can't really measure it, it's not accurate in that way or anything, it's just representative in a way we can understand it.

I've seen at least one other chart where they indicate the scale difference graphically and label it with the change in the order of magnitude. I was surprised this one didn't have one.

While this probably can't be answered because we don't know what is beyond this "observable universe", what would the end of space look like? A big wall like The Truman Show? Could it just go forever? All this "space" has to be inside of something else, doesn't it? Amazing...
