Can time travel be done?

As it just so turns out...



I have a theory. As with all my truly terrible theory's, it is very rough around the edges, but it's not like anyone's gonna actually be stupid enough to try it so whats the harm done in sharing?  (Unless of course you do try it, so in that case WhatTheJunk blog is not responsible for your stupid ass.)



So, for years people have always wanted to go back in time to correct mistakes they have made in the past or meet their future relatives 60 years in the future. (Oh and you can't change anything in the past, but I'll explain later.) It's been one of human kinds desires to be able to jump any where in time for a while now.

Why we can't leap frog through time yet.

It is theorised that to be able to time travel we would have to travel at the speed of light which is 3x10^8 m/s (that's very fast) but travelling at this speed would cause a very painful and permanent case of death. And the reason you would be dead is because of the amount of energy used to propel you at this speed and the energy that would be created by you being propelled at this speed would most likely burn and disintegrate you alive. Sounds like a fun past time. But I have been thinking and I thought a Faraway mesh cage maybe able to solve this small problem of death.

A Faraway cage was invented by a dude called Micheal Faraway in 1836 and it creates a shield and blocks external and non-static fields. I hypothesise you would need a Faraway cage/mesh to conduct the energy that would be produced when travelling at such a high speed. I'm not sure of the in's and out's of this and I know a Faraway cage or mesh would not be able to protect you against the thermal energy that would be created when you do a 'time jump' but its a start nonetheless.

 

But how would we be able to travel at the speed of light?

I have no idea. But these guys came pretty close to doing so...
 
But please don't do this to your sleeping friend.
 

Lets say Hypothetically this was correct. What would happen when we time jump?


Lets say hypothetically you found something that could allow you to travel at the speed of light (and no a giant slingshot will not do) and hypothetically the Faraway mesh enabled you to time travel without being vapourised and conducted the energy. It is theorised  that when travelling at the speed of light, you would see time bend. And when two folds bend, a tremendous amount of energy is required to absorb the jump. As energy is like a bank, when you overdraw you need to pay it back. But because no one that we know of (other than Doctor Who) has travelled to the past, we don't know how to 'pay back' the energy that we have used to travel to the past. So it could kill you, the people around you or take the energy from surrounding electrical equipment when it 'withdraws' its energy back. Who knows? But it all sounds too scary for me and Im quite content in the time that I live now. What about you?





'Once confined to fantasy and science fiction, time travel is now simply an engineering problem.'

Pseudoscience

What the hell is it?


Pseudoscience is not the same as regular science. I found this very short video to explain to you a few of the subjects in which are Pseudoscience and which are Science;





As said in the video Pseudoscience is kinda superstitions dressed up to look like Science subjects such as Psychology, Criminology and what not. It is from Pseudoscience that we have such theories about Mind control (as mentioned on a previous post), Time travel, Telekinesis, Bioengineering etc.

What makes something Pseudoscience?

What characterises Pseudoscience you mean? In nearly all Pseudoscience, all claims do not obey to a valid scientific methods, lacks plausibility because of it's exaggerated claims and lack of evidence, cannot be reliably tested (mainly because it's claims are so bold), or otherwise lacks scientific status.

And this is why it is so fascinating! Many Scientists live by 'that just because we cannot see, touch, hear, taste or even 'prove' that its true doesn't mean that it's not there'. We have already accepted Psychology and other types of Social Science's enough to actually practise them in society, so just because the theory of time travel seems a little bold and we can't prove it and we may never be able to because it may actually not exist (although I wouldn't be to disappointed if it isn't) but the fun in it is the theorising and the philosphy in it. At least that's what Albert Einstein thought when he was making his theory of special relativity.
