The size of the universe......in MILES!

[neoaeonian]

I love this. Of course you should be saying "diameter" not "Size" as the size (total volume) would be that number to the third power * Pi / 6.

On FTL travel (alien tech) clearly we don't yet understand dark energy, yet it is abundant enough and possibly powerful enough to fuel FTL travel (warping space to sidestep relativity) so you never know. Might turn out to be easy to harness once you understand it.

However big the visible universe is now, it's getting bigger all the time.

[Fotrezas]

@neoaeonian Video = 2008 = Universe expands faster than light = Univers is Much bigger than 2008 Universe

An Unidentified Flying Object flying at 547.0000000 sextillion mph over this distance would take ...... ground zone.

[5LJ3A2]

@EliteGamer001 hehehe you cannot get 547 sextillion mph as this exceeds the speed of light!

[EliteGamer001]

@5LJ3A2 Yes you are right, I can't.. but I think aliens could! :)

[papisNY]

how to calculate when some one travel for 3 months of speed of light and some one here gets older?

[5LJ3A2]

@papisNY I am not sure, although it will be something to do with 'general relativity' I think.

[bendix109]

@5LJ3A2 Dude, you wrong! observable universe is 156 billion light years wide, not 93 billion light years. You can look it up on space. com here is the link w w w .space. com/scienceastronomy/mystery_m­onday_040524.html

[5LJ3A2]

This has nothing to do with this video, but its the only place on the net where I get a relatively large amount of traffic. Its about a British woman who has been given an unfair trail and been sentenced to death in Texas.

[british123able]

no1 knows how big the universe is, we can only speculate

[5LJ3A2]

Read the green annotation box at the beginning - my calculation is based on the estimated size of the observable universe, i.e., the part of the universe of which light has had time to reach us since the big bang. This can, and has been, estimated by scientists to be around 93 billion light years. My calculation is a conversion of that figure into miles. If you dispute the original figure which I used, I suggest you take that up with the researchers who formed that estimation.

[dedanoe]

uni equals one: uni verse = in verse x verse out

redo your silly calculation.

[landonre]

omg u are a math whiz or did u copy?

[5LJ3A2]

I worked it out myself.

[awall017]

In concurrence with zmodem... only GRAVITY and SPACE can affect the speed of light . light travels in a straight line but gravity bends it altering distance traveled. space CAN be infinite! maybe we have infinite space and the inflation is just the speed the matter can travel (just under the speed of light, or pretty much 99.9999% which is close enough for me!!!)

[squibble94]

Sounds like Nine inch Nails

[squibble94]

WOW, that's pretty big. Also, what's the song's name?

[5LJ3A2]

Artist: Nine Inch Nails

Song: 7 Ghosts I

Album: Ghosts I-IV

[daralzand]

only 3 trillion years? not bad imo.

[zmodem]

However, these figures are only relative when we take into consideration that our 'visible' universe is only about ~13-14 billion light years in any and all direction. This figure is only based on what we can see, based on the limit of light speed and how fast light has traveled to us. The universe, by any means, could be infinite.

[vidstrika22]

sweet

[partywithdjvit]

nice calculations but it would have been better to be more accurate. You forgot that space expands.

[brandeezy108]

the size of the universe really all depends on when you measure and record it because the universe is constantly expanding. meaning the universe was possibly 546.3379554 sextillion miles for a split second and then the size just greatly increases from there.

[xIntoThePitx]

Same thing happens to a woman once ya put a ring on their finger.

[brandeezy108]

LOL! XD

[Scorge120]

he said the estimated ENTIRE universe, not the observable universe.

the observable universe is estimated at between 13-15 billion light years in diameter. That's because it's estimated at about 13-15 billion years old.

[2inchfloppy]

how could we possibly be able to scientifically determine the size of an infinite universe?

 Even if it was that far, what happens when you reach the end? Do you fall off?

[Scorge120]

You can't reach the end simply because you cannot travel fast enough to reach the end.

The observable universe is how much of the universe we can actually see.

If light had infinite speed then we could see the entire universe, since lightspeed is only 186,000 miles per second, we have to wait for the light to get within range of our view.

Confusing, yes, once you know it, you return back to step one again with another million questions :P

[RyanB0011]

You can't reach the end. You can't exceed the speed of light. The only exception to the rule of general relativity is that space expanding. Space expands at a speed greater than that of light.

[DragonTheSlayer]

universe might be infinite although it doesn't mean it is. You will not fall of the edge because the space is expanding in a rate which is faster than a speed of light, so you will never get to the edge (if it exists) What they mean by determining the size is the size of the "Observable" universe, meaning as far as we can see with telescope (Universe might be far bigger but the light didn't have enough time to reach us yet);P

[shawndimery]

Because for a start its not infinite, its expanding which means its finite. And you wouldnt fall off 'the end' because its not flat

[5LJ3A2]

Search "Universe" in Wikipedia and read the second paragraph of the introduction.

[ICEKamiKaze]

OMG lol

[flubberdubber]

Is the universe actually that big? 93 billion light years sounds like a HUGE distance, but isn't it kind of small for the universe we live in? Its like comparing the Mandelbrot set, you can study this figure forever and you still won't get every detail about the picture. That is how the universe is, you zoom into a dark area, you find more stars, planets, blackholes.

Nobody knows if its actually 93 billion lights years across the universe, there for its impossible to measure the distance.

[dr3behemoth]

sextillion miles.haha sex

[benshehzad]

youe sense of humour is admirable

:-)

I removed red thumbsdown

best of luck for the one left

And your sense of humour is fine.

[jacksonbrownbear]

The universe is much larger than that. You forget we can only observe out in all directions the light that has reached our eye. If you were to observe out from the edge of our observable universe..?? how much further could you see

[SubaShinY]

wonderfull! XD

[youngglasskid]

that was quite brilliant mathematics

how did you figure it out

kudos

[5LJ3A2]

thanx....got size of observable universe from wikipedia (93 billion lights years) and worked out how far light travels in one year and multiplied the two together...

[Nickcorvetteman]

But, if the universe doesent last forvever something has to stop it and also go on forever for not causing something else to appear in the universe. Just a thought

[canuckman87]

beyond the universe is empty space which just goes on forever....unless there are other universes.

[ImtheTroubleIn421]

umm well for all we know it could go on forever. Everything is black because light hasn't been given enough time to travel that far. It's also true that the universe may be expanding faster than light itself making some parts impossible to see.

[jojojojo123098]

not to be a prick. . but things are black because of tiny particles in space (dust, gas, and debris) that sorta function the same as fog on earth. so light is basically blocked by those trillions of particles. and nothing travels faster than light silly :P. it would take an infinite amount of energy to do so. forgive the poor grammar :(.

[Nickcorvetteman]

thats amazing how big the universe is im only 15 and i dont care if im a space nerd. Does anybody know whats beyond the universe?

[jojojojo123098]

nothing. matter from the expanding universe hasn't reached that distance yet. plus it's theoretical that there even IS anything that far. unless it's just another universe? :O.

[shawndimery]

look up the multiverse, and prepare to have your mind truly blown!

[eagleultralights]

Good work.

Its too bad that in our lifetime we will never know what the entire universe is like except for some cyberspace animations.

[glennlopez]

which begs the question... why the hell are you americans still using the imperial mesuring system? you people are retarded

[spacehelmetforacow]

the insults towards my country notwithstanding, i agree with you. metric is a better idea (its certainly easier to do math with.)

[D4LL2KY]

he said sextillion LOL

[5LJ3A2]

"Sextillion", as funny as it sounds, is a real number - its multiplier is x10^21 [using the metric system]. To find out for yourself search for "names of large numbers" in wikipedia.

[MeX2004]

Indeed this universe is very huge, it is huge beyond belief. Not only it is huge it is also zoned, like the zones of galaxies and cluster of galaxies. Lots of people ask the question whether there is life out there beyond planet earth or this is all the life in the entire universe. I don't know about you but I believe that not only life exists out there, universe is teeming with life and seemingly out of reach deep space is not so out of reach at all. In fact this universe was created for us.

[MeX2004]

We just have to figure it all out and we intend to do just that. As for as finding suitable places for finding habitable planets goes every solar system in the outer edges of a galaxies is a potential habitable solar system. Unlike stars forming in the core of galaxies the outer solar systems seems to be older stable systems containing rocky planets. Once you have a rocky planet the size of earth or larger in the habitable zone with liquid water than presto -- you have a planet full of life.

[MeX2004]

Keep in mind that every planet or a large rocky moon of a gas giant in the habitable zone will be somewhat different in its composition to other planets therefore every planet will have its own unique set of life form on it. You see, once there is liquid water present there will be plant life form and once there is plant life form there will be oxygen in the atmosphere and once there is enough oxygen we can safely land on it without protection.

[5LJ3A2]

Yeah....interesting stuff!! I agree with you on the possibility of alien life forms....but how could the universe have been created for us???? Who created it???? I'm not religious and do not believe in a god...

[tommyk77]

Exactly. Created? What created the creator? What was he up to before he created it?

Thanks for the video

[rockerfrog25]

our collective desire "to be" before we even existed caused everything to be here maybe
