Fastest means of Travel through space

This idea came to me like when I was sitting like Newton. When an apple fell on him he founded gravity. I may just have discovered the fastest means of travel through space.

We all know that the earth and all planets are rotating very fast.What happens if it were to suddenly stop?? We would just be thrown into  space  at that blistering speed.

Could we ever use this phenomenon to LAUNCH a SPACESHIP into space, it could very well solve our problem and enable us to reach distant galaxies.

The earth has a radius of around 6378 km. That means the circumference is about 40,000km which we are travelling in 24 hrs. This means a speed of 1670km/hr. I was not so good with maths from day one. Hence I leave the calculations of angular motion to you guys.

What I want to say is that the earth could easily be one of the most slowly rotating planets in entire space and even then any body at rest is travelling at 1670km/hr.

It means if suddenly when the earth were to stop, the objects on its surface will be thrown at this speed because of the Centrifugal Force.Of course gravity could play a part in slowing down.

Consider if we could find a heavenly body(planet,satallite or asteroid) that is rotating at a very high speed and whose size is small which reduces gravity,Our Problem reduces to finding a way to stop the panet from rotating.

I would restate the procedure in steps.

1.Select Body: I would prefer a satallite or asteroid which has high rotation speed. This is because when size increase, gravity increase and we have to decrese gravity as much as possible. I would say Satallites of Jupitur or Saturn would be up for it.

2.Place Spaceship: We must place it along its equator to gain maximum speed.

3.Stop Rotation: If I knew how  to do it, I wouldnt be blogging around. But I have a prospect for that too.

Rotation is a purely mechanical force which originated because of Big Bang and hence we cannot do much about it. But there is a large deposit of magnetic material in the earth's core which act as  bar magnet. If we apply a large magnetic force  repelling the earh's magnetization, we could stop it.

See You Yesterday

Want a ride? Well!!! How about one through Time. Time Travel may be the new form of Transportation in future but are you ready for it???

Today everybody says "See you Tomorrow". Who knows what the future holds could be "See you Yesterday".

Albert Einstein has proved contradictially(By theoritical arguments and not technically)  that whenever a body accelerates, Time slows down for it by a factor E(epsilon) called Lorentz factor. But this becomes considerable only when the body travel at speed matching the speed of light.

This can be Explained by an experiment called "Twin Paradox" .It says that if there are two twin brothers and one of them was an astronemer, and takes off in a spacecraft to a distant star and returns home,the journey done at the speed of light. when he returns home his brother would be twice as aged as him. It means he is in FUTURE.

It is because, each time the space Craft accelerates,time slows down for him.

Time Travel into past is highly unlikely as it can change the whole course of events after it reached in the past. The only explanation given is based on the Parallel universe theory.

It says that there are large number of similar universes in space. So if someone reaches in the past and changes some events, it can lead to another universe independent from ours.

Download Youtube Videos with EMBED DISABLED

You log on to the most famous  site YOUTUBE to download the most awaited and anticipated video song of your favourite pop star only  to find the EMBED disabled and you switch off in disgust and disappointment.

If you are that kind of a guy, YOU ARE IN THE RIGHT PLACE.

Well most of you would be using some plugins of Fiefox to do the job too.But here is how you can do it manually.

All you need to do is to understand the relation between the URL that you have and the EMBED code that you are seeking. 

eg: The URL of a specific  video looks like this  :

http://www.youtube.com/watch?v=9hLXeLYLu0A

There are two variables inside an EMBED code "value" and "src" whose values are equal and  based on the URL.The rest of the code is same for all videos.

They can be Obtained by making some variations to the URL at your hand. Delete the "watch?" and put a "/" in place of "=" and enter these in the end "&hl=en&fs=1". So that the URL now looks like "http://www.youtube.com/v/9hLXeLYLu0A&hl=en&fs=1". This can be used as the valus for "src" and "value" variables inside an EMBED code. All you have to do is this:

1. Copy the embed code of any video with good clarity.

2.Modify the "value" and "src" variables inside it to the value that we have formed.

3.You now have at hand  the EMBED code that you need to download any video. You can now use a YOU Tube downloader to download that video from YouTube.

Have a happy Time
