Time travel

Albert,

It is no illusion. It is real. That is the definition of reality. To each deminsion or in this case individual to thier self.

Darwin

KPM,

Feel free to chime in any time.

Darwin

Tie it together,

If you think the computer is the invention of one man it would seem this is unlikely.

What we are seeing is "evolution" in progress. Our eys are now able to go were our body can not. The creatures we made(Sound familiar) are now crawling around on another planet. Soon we will evolve to the next level.

Its evolution. The universe is changing to better see its self.

Darwin

Great to talk with both Einstein an Darwin, not bad!

Here is my assertion:
Present time does not exist.
Every thing has happened. We only see things happened in the past.

If I was on the Moon, and you where on Earth, we would have our own time-capsule around us.
Separated by approx. 1 sec. Where is the reference of present time ?

A question:
Does an object exist if we go 1 nanosecond in future in our own time-capsule ?
How about if we was there, what would we see?

You missed it Mizar. There is only one "now"

Darwin

Now hasn't happened yet ...

Mizar,

start at the beginning and read the whole thing. form an understanding

Hi Guys,

Well this whole time thing gets worse to get my head around, if it does not exist why is it in every known equation fron relativity to qauntum physics, how can it not exist we have to believe in it because of things like E=MC2. Although when you sleep and dream the dream often only lasts a few seconds but you will have exprienced something that went on for hours now where did time go there? It also begs the question whether the human brain is big enough to understand it all anyway. We can make a Bomb though using E=MC2 clever eh?

KPM,

You are the reason for the season so to speak. Start at the beginning and read the whole thing and then come back. you are just like me . you try to start were you want to, but you need to start at the beginning.

Darwin

Maybe ... each person's (being's, animal's, plant's) reality is comprised of what information has arrived at that being.

When Wolf in America talks with Candy in Iraq, there is a moment's delay between their questions and answers. Even if Candy shows Wolf live video of a bomb going off, in Wolf's world, it hasn't happened until a moment later when he sees it.

What's happening right now on that new exoplanet 22 light years away? The images we see right now through our telescopes ... little people driving 1980s cars and wearing 1980s hair and listening to 1980s music.

And when they show us what they see of us through their telescopes ... John F. Kennedy ... and the Beatles.

Maybe none of it is real until it congeals in our minds.

Give me some of that, But dont worry, just look to god and you will get there.

Actually even the word "real" only means "official according to the king's standards" (like "royal")

So even the words we use reveal that it has always been difficult to pin down what is.

Wayne,
You a thinker. give me something to go on.
Darwin

Well, I'm humbled to be in the presence of Darwin and Einstein!! Just thinkin out loud!

I like your thought that the universe is alive. Depending on how we define life ... the sun is alive, consuming hydrogen to make helium, iron, heat, and light. It will outlive us by a long shot, still doing what it wants to do.

Maybe storms are alive. They consume energy from the air and travel around to see the world.

I also liked Einstein's does-not-exist illustration! Fascinating to think from the perspective of the photon.

re: time travel ... well I think of an animal's life as like a very tightly controlled fire. We travel along a thread of fuel, changing reduced carbon into oxidized carbon, using the resulting energy to climb mountains and store memories.

What would it mean for a fire to go back in time? The fire would have to function in reverse, pulling carbon dioxide from the air, adding heat and water to create wood and oxygen.

For us to go backward in time we would have to combine memories, CO2 and poop to create oxygen and burgers.

We'd also have to pull the entire universe back in a little tighter like it was yesterday. If we don't do that part, we're not actually traveling backwards in time but just mimicking the past.

Wayne,

You are the eyes of god. You are to god as your arm is to you. Look it in and give him a show. See the wonder, Thats what your lord wants to see.

Darwin

I think it is accepted that if you travel faster than somebody else, time does move more slowly for you than for them. E.g., the space shuttle astronauts gain a few seconds, or milliseconds or something.

But I think even so ... if you travel away from Earth in a straight line, the amount of time you gain is very small compared to the time your message would take to get back to earth.

But the faster you go, the greater that proportion would be. Psst - Is that right Albert?

Here's a good NOVA site on relativity and time travel:

http://www.pbs.org/wgbh/nova/time/

You can slow time down relative to someone else's experience of time, but you can't go backward.

Ah but if you went backward, wouldn't you forget you went backward

At the beginning there was nothing, time did not appear until hundreds of millions of years after the Bang. If I travel faster than light toward a star I am going into the future as I will see it age 20 years in a week, I will consume and pass decades as I consume and pass the on comming light. Throughout I am always in the now, when I return and look back a week later I see the star 20 years younger once more. If I keep acclerating away from this star I will see it getting younger, hotter and brighter until it ceases to exist, am I going back in time or just in the now still?
