1. ## 1G Relativistic Rocket Ride, Wheeee

if I count the vectors of the rocket I will say , it will accelerate in curve way that means - at least for me - the acceleration will divide it in x ,y and z maybe it will go like twister way . or maybe those rules doesn't count in this situation . I did read some wikis things about acceleration it's seem the equations can't used in 1G relativistic state .
2. ## 1G Relativistic Rocket Ride, Wheeee

who said I want reach the moon to speed of light ? I just want to accelerate it > 0 in noticeable way . I'm still laughing but really that was the best answer. I guess we have to wait another a billion years to discover the moon escaped from the gravity of the earth. ======== can someone tell me if this motion will goes in a liner or a curved way . as I now the velocity increase with the time in liner way . how can I calculate the acceleration in every moment , with variable (v) and (t) ? as I know ? a = dv / dt or vf = vo + at (f = final , o = original ) or something else . I mentioned before but I didn't notice that things . as we know thrust comes from the blast and that comes from fuel . and of course fuel has a mass that mass connected with the spaceship .so with same thrust and a variable mass of fuel on that ship will make the spaceship continue at 1g until the fuel will be zero . in that way it will be more logical . I have to take my ticket in that journey .

I'm not sure if you understood the idea . maybe you didn't read the whole story take this example and explain it for me more . I want move the moon so I decide to built a machine ( the rocket moon ) the head of the rocket it's moon it self and the back of the rocket will be the machine look at this picture . if I start the machine do you think the moon start to move or not ?

"force would be force" it's true but there is a less and a more force at 1st newtons law ". Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it." as based of your theories and 1st newton's law you can move 1000,000 tons on space with one finger if and only if that is true then your theories will be true . but I can't see that happening . our space most of it is empty and there is a moon and it's on an empty space without any resistant , that moon has no atmosphere so if it's hitting by Meteorite ( as it's a moving object it means it has a force or at least what Newton thinks) it should force the moon to accelerate !!! why would that not happening . still all the three Newton's laws confusing us I don't know what does Issac Newton mean by "external force is applied to it" ?

yes that exactly what I meant before . lets see it in other side ,you can't get a full energy from a constant force - as mass it not changing (again relativity things)- maybe it's more complicated. I think force and energy are two sides of same coin .I mean if the force are constant how does you will get more and more energy ? for now , this is the only things I can say .

1G of velocity yes, but I'm not sure - as I'm not physician- it happens with acceleration . I will take newton's theory of action and reaction . in simple way ( there is a lot example but I will chose this one ) A and B two different of mass on the space (two different guys try pushing back together) if: 1-mass A=B ( and they push as same force this mean they separate in a same acceleration ) 2-mass A>B ( and they push as same force this mean acceleration of A will be less than B ) 3-mass A<B (and they push as same force this mean acceleration of A will be more than B) even all those state and movement object ,the acceleration will be zero again until they get more force greater than before . ( vectors things) maybe the relativity has related of these things that was all what I imagine of the movement in the space .so it just theories in my head .
8. ## What is time?

I will look time as thing changing from point a to point b .
9. ## 1G Relativistic Rocket Ride, Wheeee

you really hit something at that speed and make another big bang on our universe . I think mathematically it's possible -I actually thought about that before - but physically it's far from possible . at 1G of acceleration and every point of it you need more and more energy to keep you go that acceleration . 1/ million million million ...etc mistake of direction make you go in curved way . I don't know why most people still imagine they can travel in liner way. even in the earth you traveling in curved way .
10. ## Google earth (sky view)

Not for along time google earth upgrade their program to sky view ( stars & solar system and galaxies ) . for me this was the best idea as most people like astronomer and enthusiast have a hard time to find stars and galaxies . so is this pictures and the directions are real or fake ?. most of them looks like they are real stars and real galaxies even the directions of it . and sorry if this topic was mentioned before .
11. ## Here we go again! (New LHC Fears)

Scientist of good looking
12. ## I hear something ?

I hear these sounds since I was kid maybe 5 or 6 yr old . I need go to the doctor.
13. ## What is the total sum of all numbers?

that remind me Laurent series
14. ## I hear something ?

tinnitus , I thought that was another one it happen when I hear a very loud sound , my ears drums vibrate in unnatural way. you really don't hear a thing when you close your ears ??
15. ## I hear something ?

who knows maybe you're right .
16. ## The Official "Introduce Yourself" Thread

-I'm empty -27 yr -I like No: 3 and hate No: 0 -I still don't know how can I see things -more thing confuse me it's how did scientists discover a black hole at same time it sucks every things even the light -there is no perfect in our world -I still don't know what's a nature ? -and I'm in love ( yes I know I'm lucky)
17. ## I hear something ?

No I think it's more like a high frequency sound . I hear it more clearly when there is no sound else around me .
18. ## I hear something ?

thanks for replay , I'm not sure if you understood me . I actually meant by putting your finger on your ears -a full closing- . and thanks again .
19. ## I hear something ?

when I close my ears by my hand . I hear a noise actually two different noises . one of them with different vibration -frequency- ( like something exploding) and other one has same vibration -frequency- it's more like ( toooooooooo ). any one know what are those sounds ? and I'm sorry if that was a stupid question
20. ## what is the universe expanding into?

IMO at some point the universe will stop expanding .maybe the reason will be the reverse gravity of the universe and start back to point zero . there are a lot of things we didn't take it maybe one of them is time , our universe made of galaxies and that made of stars . some of them died by explosion and others became a black hole . my point is we can't imagine the expansion of universe if those things disappear or vanished . those things will die soon or later before they can expand .all people here imagine the expanding things but they didn't take changing thing ( time ).
21. ## Do you believe in God?

believe it if you said " Oh my god " if you fear the dark , when you know there is nothing to afraid about it. if you fear the death and you know there is nothing to lose if bother your self to think he exist or not exist . when you don't believe it .
22. ## Does the Soul Exist?

I mean that's same what does wiki mean soul
23. ## Does the Soul Exist?

As all people here (scientists) with a little or more knowledge ,do you think there is a soul on some matter and not others - as we know, we are just atoms ( gases ,solids,liquids) . do you believe those things has a brain to thinks to creates a cell (a live object) moves by it self and begin to evolution . If the matter is not alive things how did they creates alive one !!! . At first I didn't understand the quotes that says people made of mud. as what I understand mud means ( gases,solids,liquids) in general way. so what is keeping the body alive ?
