i'm afraid I'm too dumb to understand that :haha:

oooo-k... Let me try explaining it to you a different way...

... Planet of the Apes... yes the movie (not the actual planet)... No the original one! You travel at the speed of light around the universe and come back to Earth and billions of years have passed, but you are just a few months older. Got it now?

Umm I got that idea from the beginning but how I just couldn't understand it logically speaking. I can grab the idea but not understand why it is so.

we will probably never reach those planets. Maybe in our solar system but not beyond

We would need to figure out or find a

Worm hole.
Black hole - then we would have to suvive the black hole according to scientist eveything breaks up inside the black hole.
Warp drive - speed of light travel.
Gravity.

To travel from one end of the milky way to the other traveling at the speed of light would take 100,000 years.

A worm hole would be the best way to travel we would get to our destination in seconds. Im sure thats how the Aliens do it. :DL

Mass Effect 2 game got me thinking about this.:DL

Again time is Subjective. For a travel going about the universe at c the time it takes to travel is a lot less. For the Objective observer here on Earth it takes the full 100,000 years to travel make the trip.

I don't pretend to understand it but that is how Relativity works in its counter-intuitive way.

I don't see how a Black Hole would help you get anywhere except the great here after. Unless you are talking about harnessing it for power or something.

There is nothing at the bottom of the singularity. Unless you start talking about quantum physics and the destruction of information.

It's quite the opposite, actually, everything is compressed inside a black hole due to the infinite gravitational pull in the singularity, so nothing would quite break apart. Not much use for interstellar travel in either case, though.

Speculation is fun n' stuff, but I've held to this concept:

Not only is the Universe capable of more than we imagine, it's capable of more than we can imagine.

I think they do 'break apart', but not in the way being used above. The electron bonds get broken when the atoms get crushed under the immense gravity, therefore releasing the bonds. Since it is a singularity. then the structures of objects no longer exist. The debate in physics continues though over if the information of these structures remains, ie Hawking radiation and all the associated issues.

Actually it works both ways. The faster you go the longer it takes the light from your starting point to reach you, hence the slower things there would appear to move (assuming you could see them). Unfortunately relativity works both ways, so the light from your spaceship would have the same problem, so the reality is that time would seem to slow down on earth if you could see it.

Or at least that's the way it would work for two spaceships, since neither one is travelling at all except when compared to the other.

Buuuut...

Gravity seems to throw that all out of whack, so to a person in a gravity well (such as a planet like earth) the spaceship, which has no gravity of its own (none to speak of anyway) really would appear to be passing time more slowly. Here's a simple explanation:

And this one's a little easier to understand:

Looks to me like we either get one of these or we ain't going very far:

So many new places to go and no way to travel to them.

Space is amazing, even if you don't believe in God, space itself proves time and space itself are eternal. To think no matter how far you look backward or forward, it's non ending.

We don't have the technology or sources to travel space to use any planets. Unless life comes from another planet, we'll be here using earth up.

Course the year 2012 is coming soon and it will all be over. :woot: I just hope it's not another ice age, I hate the cold.

Well according to most accepted theories if you look far enough back you will eventually see nothing because you will be seeing the universe before the big bang in which time at matter didn't exist. As for the end it depends on what theory you subscribe to, but most either way end with all matter in the universe coming to and end, with out any matter measurement of time becomes nearly impossible.

Sometimes I feel like I'm talking to my self. Everyone seems to underestimate humans, and what they are capable of. When I build my Orion for my Rigel Kent flight none of you can come along...

...except maybe Oberon, ML, Luftwolf and Vendor.

Nothing...is still something, emptiness is still space. The big bang may have happened out of thin air....but thin air is something. Time and space is non-ending.

I don't underestimate humans, I expect them to do what they've always done, take over and destroy civilizations and then rebuild again, it's just now the damage we can do can set us back to the dark ages.

Humans...humbug..

Tchocky 02-21-11 04:27 PM

Our galaxy itself contains a hundred billion stars, it's a hundred thousand light years side to siiiiiiide

Platapus 02-21-11 04:52 PM

It is kinda sad that there will be places in the Universe that humans can never explore.... or it may be a good thing, depending on your perspective. :D
