Man, the math makes my brain hurt

Time travel isn't possible. If you went back in time you would be adding matter to the universe by creating a second you thus creating something out of nothing. If time travel were possible we would have known it by now. At least that's what the aliens told me.

Gotta love those Aliens they are usually right

there are many bridges to cross, the first being that you have to apparently create a naked singularity. that sounds easy- you just take the clothes off. unfortunately, unclothed (and thus lewd and lascivious) singularities are illegal, so you might get arrested. furthermore they may destroy the universe just by existing, and also cause a great deal of other problems like time travel, information paradoxes, eating your entire planet, hawking radiation megadetonations, and other things of that nature.

Time travel does exist! Everyday I look in the mirror I see this older version of myself staring back. I could swear I was still in my 20's. [8D]

[Twotribes]

I believe time travel may be possible BUT when you go back you either can not interact with the world OR you create a new thread that does not effect your actual present. Otherwise we would know by now.

Funny, I am watching right now the series on History Channel called Ancient Aliens.

You should meet my friend Dorian Gray.

Here's the more interesting question. If you could, would you?

There are questions which we might not want answers to.

You go back and change something, and in the process, you end up worse off than if you had left things alone.

Arthur C Clarke wrote a novel called the Light of Other Days. Awesome read. In the book, everyone ends up being able to see everything ever. Zero privacy. Think about that, no privacy ever again anywhere. Every mystery solved. Every truth known. All the mistakes revealed.

Ever wondered about something to which everyone is interested in the answer, but no one likely really wants to hear it.

Myself, my life hasn't been easy, but, I'm alive now. I think my future is looking up. I'm due to get married this year. I have a great son.
There isn't a single instance I'd risk changing. Maybe I change something, and I never have my son. Unacceptable result.

Did Christ really die? (one of the elements in the book).

Very true....

warspite1

Yes, defo!

So - and with military history matters in mind - if you could go back in time just once and can try and affect one individual battle (or specific incident that led directly to a battle), what would it be and why? What would you hope to achieve and how would you like things to have played out?

In order to affect the battle you can go back as anyone - politician, general, soldier - and can do whatever they could realistically do.

Iswandlwana - and would Pullein to coral his troops around the ammunition wagons. And defend the colours obviously.

Is there a money back (or time back) guarantee?

[TulliusDetritus]

I haven't read the PDF. Looks like Mandarin Chinese (the math) to me.

I always remember an Italian friend. Most people would go to ancient Egypt, Middle Ages or whatever. He would travel to the future, er, to next saturday to be more precise, would write the winning lottery numbers and back to his "present". And voilà, one week later Forbes magazine would be talking about his obscene wealth... Moral of the story? He loved his present but he wanted the money... the most convincing time traveler I have seen eh

Who's on first

[Curtis Lemay]

Personally, I would never want to travel further back in time than the invention of the flush toilet and electrical grids.

It's not time travel we want. It's to see back in time.

That's actually doable: Look at the sun and you're seeing 8 minutes in the past. Look at Alpha-Centari and you're seeing 4 years in the past. Look at Andromeda and you're seeing 2.5 million years in the past.

So, what's needed is to be able to violate Einstein's law about faster than light travel. Then you put detectors out far enough to capture the light from ancient events, with enough aperture ranges to resolve those events.

Do I have enough for a patent?

Bi-location would be the way to time travel. Your body stays here your spirit goes and makes a visit to a far away planet. Your spirit travels in time no need for a space suit. Don't laugh some have (its been claimed) been able to.

You need to include a working model in order to to apply for a patent.

On the other hand, it doesn't really matter when you invent time travel - you can always travel back and patent it earlier.
