How Are Black Holes Created?

The Creation of Black Holes:

A star.A star shining in the sky light years away.It looks so calm and peaceful,but from up close it's hell.Nuclear fusion of simple Hydrogen atoms into more complex ones like helium and some other heavy elements releasing tons of energy. 







To do this on earth we would need to get the hydrogen atoms far hotter than the actual surface of the Sun,so how does the sun do it?

Quantum tunneling of course.Even tho' the atoms aren't hot enough they fuse anyway.Remember that the sun is so huge that these small chances happen all the time.That's the life of a star.But to learn how Black Holes work we might have to look deeper.It's birth and it's death.

Clouds of dust floating around space getting thicker and thicker until it's density is high enough.The cloud explodes creating a ball shaped object that has hydrogen atoms in it,starting the fusion as soon as it's born.This ball of light also has gravity.


Now let's look at how stars die.Stars run out of hydrogen atoms to create energy it explodes like a huge hydrogen bomb(Supernova) releasing gases that push the inner layers inside putting a lot of matter into one point.This point's density and gravity becomes infinite thus creating a Black Hole.

Size:

Sizes of black holes depend on the star and the size of supernova's.
The biggest black holes are usually in the center of a Galaxy.For example The Milky Way has a black hole in it's center.What do they look like?It's a dark circle that not even light can escape.This is all theoretical remember,i wish it wasn't of course :3

Hawking's Radiation:

Can one escape a black hole?According to Hawking's work,yes.But that doesn't mean you will be in one piece.You will be shattered in particles that is.

A black hole isn't a perfect prison.It leaks particles and matter over time,the smaller the black hole is more it leaks.


Re-a range particles and you can get your stuff back :D

Where does it lead you?

I don't know.

No one does,as i said it might be a wormhole.But even if it is,there's no way you can jump in without getting destroyed.

On my next post i'l go into deeper details about black holes,this is just a brief explanation of it's birth and it's death,as well as the stars life,after all these two are so related that they kind of resemble the same thing.

Dimensions,Timelines and The Void

This post is based on Doctor Who mostly.This BBC's British TV Show sure is smart.It triggers questions in our minds that we've never thought off  before.

So yeah..spoiler alert:

Let's start with Rose.She found herself in a different dimension living that boring life while the doctor travels through space and time with his other companions.This "dimension" might as well be called a parallel universe.




Anytime you make a decision a new universe is created in witch that decision isn't made.So if that's true there's millions of different universes.In one I'm dead,yet here I'm alive,same as Rose's dad.

So Rose was trapped in a parallel universe in witch her dad is alive,but she can't come back since the TARDIS can't travel through universes.This can only be done with a hole in the fabric of reality.
Too bad for her,but keep watching the show and you will be amazed 




Hmm you know i wonder..The Doctor said he mustn't change history,but he's doing it all the time.His answer to this question would be "I know what I'm doing" but..does he?

So judging by some episodes you can tell that some events are fixed,and some are not.The Doctor can't change events he didn't participate in.

The other theory would be the already known Harry Potter and The Prisoner of Azkaban.The Doctor goes in past and sees himself,helping him,changing history without paradoxes....I'm confused.

It's weird that the all mighty TARDIS can't travel through parallel universes.I wonder what's in between those.Oh yeah,The Doctor explained that too!The void.Sounds pretty cool eh?


This is what the Void looks like...But there's no colors either



What is it? Nothing. Just nothing!
There is no matter,antimatter,space nor time!

I wouldn't wanna end up there :<

Possibilities of E.T Life Forms

Extra Extraterrestrial Life Form Possibilities

This might be a little bit off the time travel topic,but it's still interesting and after all,this could still be fun for Whovians :)

The universe is massive,huge,endless.You cannot say there couldn't be any other planets with earths "life gift"

Earth,the water and oxygen creating a perfect atmosphere with the temperature.It's rare for a planet to be formed at the distance from the star to support life,but since this universe is so huge,there must be another planet at the same distance,size and gravity to support life.






But perhaps our answer is right in front of us.The Red Planet,Mars is believed to have been a home for life.If there was life,it were microbes and bacteria.Still it's pretty cool thinking about this.

Another interesting topic is space colonization.Imagine living on Mars or the Moon.Pretty awesome isn't it? Well not really,there's
a lot of unsolved problems.

First we would need basic stuff a human needs to survive.Food,water,oxygen.That wouldn't be too much of a problem if we bring enough.The next obstacle is gravity.Oh that gravity.


We'd need a planet similar to Earth in size due to our gravity requirements.Why is gravity important?Well simply because our bodies would rot.Our muscles exposed to low gravity levels would be useless,so the body would burn them out.On the other side,exposed to too much gravity would break our spines and bones.

This can be solved tho' if we could simulate gravity.Another problem is radiation.Who knows what kind of radioactivity there is in space.

And the most important one.Staying.Life would be awesome but hard.Traveling there would take a lot of time,maybe years.But if we decide to make buildings on the moon,it might actually work.

If we can overcome the simple obstacles we could do it.But the moon isn't our target.


Jupiter has a moon,a natural satellite orbiting around it.This moon is called Europa and it's the only possible life sustaining object in the Solar System other then Earth and possibly Mars due to having oxygen in the atmosphere and oceans of water on the surface.

But the space age of humanity has just started.The universe is huge and one day humans will explore it and find new life forms.

If only we lived long enough to see them,but who knows 

Paradoxes:

PARADOXES:

What is a paradox and what does it have to do with time travel?
Well paradoxes are kinda the problems in time traveling.If the classic paradoxes that involve time travel existed,and people could time travel the universe would collapse!

So first,let's find out what a paradox is. It is something that leads to the same thing.Or as wikipedia would say :

"A paradox is a statement that apparently contradicts itself and yet might be true"

To better understand this il' give you a few examples:

"This following sentence is true"
"This previous sentence is false"


This one is known as the Pinocchio paradox

This one is known as the "mindfuck"

Ok,so that's a paradox,what does it have to do with time travel? A lot!

Let's take a look at the Temporal Paradox,also known as the time travel paradox.

A time traveler goes to the past changing it and disabling himself to ever become a time traveler.How would he do that if his past self will never be able to do that.

An example is the grandfather paradox.I have a time machine so i go back to the past and kill my grandfather for some reason...So if i killed him before i was born i would have never been born,there for i could have never killed him in the first place!




What would happen?No idea!That is if we aren't talking about Harry Potter And The Prisoner of Azkaban.

In the 3rd book of this awesome series our heroes go back in time to help they're past selfs(without them seeing 'em ofc)

So thier past selfs could do the same thing to they're past selfs...

I'm sorry if that doesn't make sense.I'm trying my best.

If you want a video about it just watch this one:


It explains these paradoxes a bit better.I mean after all it's moving pictures not text.

The Warp Theory and The TARDIS

Warp Theory:

Believe it or not,the warp theory is from a sci-fi show.Yeah,Star Trek.It's pretty much using a force field and gravity created from the power of matter-antimatter collision that moves objects in space to allow incredible speed.The thing is the spaceship stands still while warping,it moves the universe on the other side of the vector.

Got it?Good

THE END

No,but really.It's silly because time traveling is going Faster/the speed of light,not standing still while the universe moves.

Of course if the universe moved the speed of light you would be time traveling,but i doubt some matter-antimatter collision could create enough power to move the universe.




How does the TARDIS Work:

So,everyone know what a TARDIS is,if you don't i shall explain.

It's a Time And Relative Dimension In Space spaceship that travels:you guessed it:through time and space.

That was simple,so could The Doctors spaceship really work?




In fact:Yes,yes it could,but this kind of science for now is only theoretical so it barely matters.What the TARDIS does(my guess):

1:It creates a hole in space-time.Much like the wormholes(black holes).
2:It creates Gravity(..don't ask)that bends space-time.
3:It travels faster than the speed of light.
4:It runs on Magic.

More Speed of Light Options

More Speed of Light Options:

Well all my time traveling dreams are ruined since we can't go faster than the speed of light...right..right?

Actually,we can.I mean it's all theoretical for now,but we may be able to in the future.What I'm talking about are the good ol' famous Quantum Tunnels and Wormholes

Now to explaining quantum tunneling and wormholes would be insane since you would need to know basic quantum mechanics.
So to avoid it,i'l put down some pics and videos you should watch 

http://www.youtube.com/watch?v=cTodS8hkSDg : Quantum tunnel

Quantum tunnel

Worm hole

Worm hole

Got it? Me neither,keep reading for more:


Ok,so now you should know at least a little bit of what I'm trying to say.If a Quantum Tunnel allows you to go faster than the speed of light then you could time travel using those.

As for the Wormholes(look at the pictures) they bend space-time to go into another part/timeline in the universe.



But scientists today can't create wormholes bigger than Quantum levels so too bad.But you could just jump into a  Black Hole too.

Now Black Holes are somewhat wormholes.We could 
1:Jump in(hard to survive but should work like a wormhole)
2:Orbit around(impossible)but would work..check the other post to understand xD

So the next time you see a black hole,jump in,see what happens..That's a good idea,After all:


-Wormholes are just quantum entangled black holes




The Speed of Light Time Travel Theory

The Speed of Light Time Travel Theory:

Here's a fun one.Since Einstein published his theory of Relativity we know that traveling the speed of light/faster is pretty much impossible due to the Energy/Mass increase.

But we also knew that if we could travel that fast,time for us would
pass much quicker than the others.




Also i'd like to point out that this is just the simple explanation.This is far more complex and I don't even get the most of it.Science..


Earth C Orbit Travel

C stands for speed of light by the way,that is : 299,792,458 mps
Now what i propose is to build a satellite that travels faster than the speed of light.(fat chance)And launch it into orbit with someone inside.




After 5 minutes of orbiting at the speed of light land the satellite back.As the brave(should be dead) astronaut walks out proudly he sees his granny."Hi Granny Rose" he would say."Who are you calling Granny Jack!Go to your room"...


Yeah that story sucked but proves my point.Your family will already be dead by the time you play a game of League in orbit at the speed of light(for the not-very-bright :that granny was his mother)

To understand this better just Google it or read a book about the theory of relativity.It may sound scary but it's pretty simple.

The problem about this blog o' mine is that all of the information are from the internet.I'm afraid some may not be correct,that's why this blog should pretty much be just an eye-opener that should get you motivated to learn more.

After all you learn better if you do the research yourself.Do it.



Gather Whovians and non-Whovians + We're all time traveling!

I'm aware that all of us have at least once heard of Doctor Who,or ever thought about time travel and how awesome it would be...

Well what if I tell you that you're already time travelin'
In fact,all of us are.




In this blog o' mine we will discover the theories about time travel.
That means we will have to go through some:
-astrophysics(not as boring as it sounds)
-relativity
-astronomy
-classical mechanics

But since no one here knows any of there(I barely know that f=ma)
I will make it REALLY SIMPLE.So none of you(and me) get lost 
reading this.


We're all time traveling:

So this one is simple and pretty scary..
Don't freak out but..your feet are older than your head..
Didn't freak out? Well you shouldn't cuz it really isn't much of a difference.


Gotta love the 10th :3


Why?

Well we have to ask Einstein.I'm serious.According to his theory:Gravity bends Space-Time.That means a massive object in space like Earth or the Sun can bend time and space around it.This results in your feet being older.




It also means when astronauts come home from the ISS(international space station) they are younger compared to others.It's a few seconds(depends on how long they were in orbit)

Yes,but how come?

Our feet are older because more gravity bends the time around them.Your feet are the lowest to the ground.So they are the closest to the Earth's core than ur head.There for you're feet are faster.Pretty Weird huh?
