Time Traveling

I may have brought this up a long time ago, and if I did its probably buried somewhere and I don't want to bother to look.

Time traveling

I think it's impossible. As much as I would love for it to be true, it's just not going to happen.

Now, what little kids hasn't dreamed of flying in the TARDIS going off to adventures and traveling through time? Here's a video featuring Ronald Mallett, a professor of Physics. The video explains the rest:

Now, I don't claim to have any great knowledge in Physics but I do admire the subject. I would say I'm an amateur but today's meaning of that indicates I'm inept on the subject. While that may be true, "amateur" once meant "lover of". Regardless, here's some things that bother me with the theory of "time traveling."

Mass. While accelerating particles may be fun and all, no human body would be able to handle the amount of pressure if you were to propel at or near the speed of light. If you've been on a rollercoaster you'll know what I mean by "pressure." So, that would mean that a vessel is required. Well, if that's the case, say that the vessel would be able to contain you but the problem still lies at the fact that you and the vessel have mass, heck of a lot more than a subatomic particle. So, according to the formula e=mc², multiplying the mass by the square of the speed of light, I believe the amount of energy produced would be so immense that it could practically blow up the whole Universe because then you would become infinite energy. Or, with that amount of energy, would you then become a supermassive black hole?

Wormholes and decay. Sci Fi always had the idea of portals and wormholes way before theoretical physicist took it seriously. Well, lets say a wormhole is possible if wormholes where the answer. But, I don't believe that if a wormhole were to be produced it would take to you nothing, neither to the past of the future. Not the past because of decay. Take something simple like a human that's been dead since 1990. Creating a wormhole that takes you back to 1980, perhaps you successfully bended time and space but don't we follow a constant line that's moving forward? We age, everything ages, everything dies, everything is decaying. It's not like we leave some sort of fixed signature behind or create a marker ahead of us in order for any spectator to see. As much and I'm against the social construct of time as being an entity, everything that is made up of atoms is aging, therefore I believe if one moves back in time, you won't find anything. Same as moving forward.

So no matter when Mallett turns on his time machine, I don't believe a particle will come back to our present time from the future.

Time Machine. I believe this is the wrong name for it. There are already time machines and they've existed for a very long time, we call it a watch. If the goal is to bend time AND space, the terminology should be something different. Perhaps Time And Relative Dimension In Space?

Yes, it's fiction, but it makes a hell of a lot more sense than just "time machine."

More later.

And as always, the thread will go off topic, if you feel inclined to do so, keep the discussion related to "time traveling", don't go starting off talking about goats and French wine.

I'm trying to get a conversation going, what FH was meant to be used as.

Cool subject! Beyond exhaust right now, I'll come back to this tomorrow. Thanks for posting!

Why bother with French wine. I have never had a bad California wine. Buy U.S.A. Later, Dude.

**Camino** · 08-21-2009, 01:26 PM

^that wasn't very nice!

I can't even claim amateur with this subject, I have zero knowledge as far as this is concerned.
But none the less, I found it very interesting. Thanks again for sharing!

That was a delaying action until I have time to read up on the subject. Besides, this is Whatever. It is traditional, even mandatory to get off topic here.

If there was such a thing as a "time machine", I'd go back 10 years, stick my 10year younger self into the time machine, send him back to now and snog the hell out of that girl in FixR's avatar.

As for my older self in the past, I'd avoid the web bubble of '99, and pull out on time
(that's what she said)

Time travel has not been proven to be either possible or impossible.

Physicists take for granted that if one were to move away from the Earth at relativistic velocities and return, more time would have passed on Earth than for the traveler, so in this sense it is accepted that relativity allows “travel into the future”. On the other hand, travel to the past is highly unlikely due to several unresolved paradoxes (grandfather, etc.).

Stephen Hawking once suggested that the absence of tourists from the future constitutes an argument against the existence of time travel although Carl Sagan suggested that time travelers could be here, but are disguising their existence or are not recognized for what they are.

If you have a few hours and don’t mind the resulting headache, read the entry in Time Travel at Wikipeadia.
