Cosmic Time 5 of 6

[laurence265]

there's alot of paradox' like, a man builds a time machine, goes 2 minutes into the past and walks behind himself getting ready to go 2 minutes into the past, and shoots himself in the back of the head. how does he shoot himself before he leaves?

09:44 Why is there sound and how can we see it from the outside?

I still liked the video though! :)

Time cannot be viewed in the past by peering into space. The universe is 13.7ba nothing can be viewed 13.7 billion light years away. There should be no galaxies found at that distance. Matter cannot travel faster than light. Eventually we will find that light does not exist until it's electromagnetic wave collapses. This action occurs in an instant. Distant objects are viewed in the present, not in the past. Evidence to this, see HawaiiEdu, "Tomotsugu finds galaxy 12.8 billion light years away."

Michio Kaku is my Justin Bieber

[HimesInu]

@madridisinSpain I don't know how you see Bieber, if you like him or not, but how is Kaku your Bieber?

[outerpol]

Boring

[frextext]

is time eternal?? not for us its not. am i bothered about it?? no. but, am i hungry?? yes. and how hungry am i?? lots

thats my theory of hangover

thanks

[Ayokalyb]

the fact that people from the future are not warning us about future catastrophe's is because we never achieve time travel. or our time now is that insignificant, regardless of how "important" we think we are.

[TheMidwestsk8ter]

@Ayokalyb Why would theyinetrere n thefirst place?Thats not how it works brehh

[Herv3]

@Ayokalyb or there is not future people.

[polarspirit]

@Ayokalyb ohh yes. ever heard of fortune teller? lol

[HimesInu]

@Ayokalyb Or that you can't change that which has already occurred.

[Donshameer1]

@Ayokalyb Oh perhaps they have finally understood the concept of chaos...

[Timdenomad]

or maybe they have changed things and we were spared from many more catastrophes, but how would we know? 

[kirydawg]

@Ayokalyb or because future humans knew of the danger of interrupting the space time continuum and thus decided not to interact with us.

[phobiazzzero]

@Ayokalyb maybe just because you can get back in time but only at the point of time travel device invention

[InvertedHorizon]

@Ayokalyb Or that we've all died out in the future.

[Godreignsonhigh]

An object of infinite density started the universe and time! well what formed the object? How can an orderly earth result from some chaos. it is a piety how humans struggle to separate God from His creation. However the creation is speaking with a tone ever louder about the Creator. This world was created, and we are beings that are given the ability to discover the wonderful works of God. This is no argument, as we dig deeper, the answer will stir us even clearer at the face-GOD!!!!!!!!!!

[slipnslide1o1]

@Godreignsonhigh who is god?

[ems390]

Yes time is relative but time being relative is as well relative what we describe of as time is not really the length of existence but also the length of existence of nothing. Time existed before the big bang in another universe and existed in this universe before the Big Bang. It would also exist afterwords as nothing.

7:58 supercharger lol

[logictoo]

the music around 3:10 to 3:33 reminds me of the movie "point break", the part where they skydive for the first time. the freefall music.

[naturesaved]

Here this person said that matter will die, and energy will die and that gravity will die, but they also said that time will remain forever!, the contradiction is that, time is Relative, it's tied up to mater, energy, gravity speed and other factors, Time Is Relative!

To Edsan91 : Existence will be forever, when we master time, or any civilization who has, can always go back to the pass, and surf in time for ever.

[naturesaved]

I dont think that time exist, only matter, movement = action and reaction, and space. This ones give us an illusion of time.

Space is created by matter and energy at high condensations and speeds. Creating gravitational fabrics. Gravity creates space.

And if Light Speed is, the limit speed in the universe, then there is a limit space for all the universal mass to travel to.

So there is limited mass in our universe.

[naturesaved]

Our universal space is limited by the quantity of our universal total mass and energy.

When the end of universe comes as described in the video, the energy will calm down and the mass will get colder and light disappear,

what's going to happen is that our universe will be pushed back together by the dying of space, space will start getting smaller

and will push all the mass back together, space will start disappearing.

[Edsan91]

Thats very interesting! Thanks for posting that! But if space will start dissapearing will existence as well? Its strange and weird! Maybe there is infinite mass! but if theres time then there must be an end like u said and maybe there might really be an end! WHat if that end has a start again! like if the big bang happens again! ANd it starts all over again? Maybe there were more than 1 big bang and were on a different one? Very strange!

[rabbitpi]

it's the sports car again :)

[hnicky]

hmm that sounds strange..
