And how do you know that god isent real give me 5 reasons
Also, I ment respect your views

@arch37 We all know what kind of expert god is. We know the earth is flat , that a few billion animal species fit on a wooden boat, those virgin births , gay is bad , slavery is good, torture your kids if they dont listen to you, ten commandments ,
born in sin , and all the other great things that come to mind.
You are right , God is just great and he is so smart . We just cant grasp all that greatness and smartness and he is so holy and everything . My God i cant seem to stop ,God help me.

@GentillAbdulla Well , since i am always wrong about everything, i’ll let you explain to me how you will reach faster than lightspeed , create a wormhole , put the wormhole in the desired position, travel through and so forth.
I am really interested to know.

@COMMOGSE You guys who fight God & Jesus His Son are in for it! You fight God in me too hard & God will hit back. How dare you try to get rid of God’s child. he’ll beat you every time, because Jesus is with him not you…yet!

@xaxie1 What do you mean “we respect yours”? Atheism isn’t a religious belief; it’s actually a lack of belief. I don’t belief in a supernatural entity, so there’s nothing for you to disrespect in regards to me. If someone likes the Batman character or Spider Man, I can say fuck those guys. They don’t exist so it doesn’t matter, understand that.

travel through the wormhole. The same effect can be created when traveling at light speed.

The trip itself would seem instantaneous to you because no time has passed. But it would only be occurring at light speed.

GentillAbdullaJanuary 3rd, 2011 at 7:34 pm

@COMMOGSE Sorry but you are wrong.

In order to pass through a wormhole you would have to move faster than light.And you seem to have a misconception of what happens when you reach light speed.When light speed is reached you trip takes no time TO YOU.You wouldn’t stop in the middle of the wormhole.A wormhole connects through hyperspace meaning that it takes no time because hyperspace is different from spacetime.It is a by product of the formation of closed spacelike curves.Meaning instantaneous

@sargemajor1 Great !
That was a great movie from the 80′s you just told us about.
It was remade at least a half dozen times since then.

sargemajor1January 9th, 2011 at 8:35 pm

So at the end of the day we must answer this question correctly and not say that time travel is impossible!
But we must say that it doesn’t look likely that we have the capacity to induce it

sargemajor1January 10th, 2011 at 7:36 am

therefore the cloud storm actually created a tunnel that induced “Time Warp“
Imagine in terms of physics what was happening in that Time Warp Cloud storm.

This Pilot could have encountered a cloud Storm that took him into the Past! (back into the dinosaur day or even into Space) and he would of gone down as MIA.

sargemajor1January 12th, 2011 at 2:32 am

There was an incident where by a pilot during his flight over the Bermuda triangle area encountered a strange Magnetic cloud storm and lost all his comms with flight control, he was sucked into the storm and then he successfully rode out the storm and came out through the other end.

Flight control reported he had arrived at his location and he was shocked to hear that ,because when he calculated the distance travelled over time it meant he was travelling at about 2,000Mph.

COMMOGSEJanuary 14th, 2011 at 10:10 pm

@GentillAbdulla Lets say you created a wormhole.
In order to fly through it , you would have to reach lightspeed. Problem # 1.
Time would slow down considerably and would stop inside the wormhole. Problem #2. During your few day short trip through the hole, a few billion years have past on earth. Problem#3 . The wormhole would collapse , when you entered it. P#4 Thats just a few problems i can think of right now.

GentillAbdullaJanuary 15th, 2011 at 6:52 am

@COMMOGSE The calculated mass needed to bend spacetime enough for a wormhole is about 9.6 solar masses.Then you need the energy to move one mouth of the wormhole to the galaxy that is preferred, and move the other mouth to the entrance you want.Wormholes unlike black holes do not have massive tidal forces so it doesn’t matter how close you get.But unfortunately the closest wormhole could be no closer then the nearest quasar.Tell me what happens when anything tries to go through a wormhole?

COMMOGSEJanuary 20th, 2011 at 6:57 pm

@GentillAbdulla Hypothetical question:
Our sun bends space-time only by one millionth relative to a flat universe. How many sun masses would you need to create a wormhole that could connect two galaxys for example ? How could you control such an object ? How could you get to such an object ? How close could you get to it ?What would it do to its surroundings . And most important of all , dont you think it would be visible to us , if it existed ?

GentillAbdullaJanuary 21st, 2011 at 5:59 pm

@COMMOGSE If it is possible to alter the fabric of spacetime then you can alter it to a point where mass acts as where it was previously.

This can be done with light cones, if you are familiar with the concept, through closed timelike curves.

Since you know about the subject then I guess an introduction is not needed. Continue.

we know you can live under water, live in space even other life in space, but time travel come on guys

xaxie1January 26th, 2011 at 3:09 am

@TheR33l
How dare you just disrespect something because you dont think its real, just because you dont doesent mean others do, we respect yours, and dont go offending you so shut up and stop being mean

xaxie1January 27th, 2011 at 9:37 pm

While time travel is indeed possible, we would probably only be able to travel through wormholes that we have created, so if we did make one, we wouldent be able to travel to our relative past, only to our relative future, and people from the future would be able to visit us :)
But I think time travel is dangerous, what if it became a tourist sort of thing and we ended up paying to go back in time and people accidently caused paradoxes?
It would have to be very controlled :S

ballking34January 30th, 2011 at 6:06 pm

@TheR33l i respect your beliefs. i really do. but can you respect my beliefs and not post things the offend my religion.

plastiswafersJanuary 31st, 2011 at 12:29 pm

although i find time travel extremely interesting, wouldn’t it be dangerous to do so? if anyone could change the past to their liking, then wouldn’t many parallel or conflicting universes be created?

TheR33lFebruary 1st, 2011 at 11:41 am

@ballking34 I can’t disrespect something that doesn’t exist.

ballking34February 3rd, 2011 at 7:00 am

@TheR33l its all about respect, so please dont disrespect God in any way

TheR33lFebruary 4th, 2011 at 4:58 am

@arch37 You’re dumb as shit. Your god can go fuck himself, yes I said it. He’s a powerless piece of shit.

COMMOGSEFebruary 6th, 2011 at 12:59 pm

@arch37 I think you should visit the religious idiots videos here on youtube.
Thats a better place for you. There you and other believers can make nice little stupid comments about jesus and how wunderfull everything is.
