Aren't you two suggesting two different things? As I read it 1effect is suggesting that the light will approach the receptor at the "closing speed" which was v+c, and cadnr on the other hand is suggesting that the light will reach the receptor at the speed of light (just c), no matter if it is...
Okay, I don't know really if this is the right forum to ask this in, so I apologize if it ain't. I will also add that I am 16 years old and from Sweden, so pardon my English.
The question I have is the following:
I read a short part of a chapter in our physics book in school which was about...
I changed my mind ;) Math is proven to be 100% correct, in this world. But we cannot know if the conditions of "reality" is the same as "here". So therefore we cannot say math is correct.
Short question; Matter attracts matter, black holes even attracts light. If all matter in this universe was together, wouldn't that create big enough gravity to never let that matter go? Or would it create some kind of implotion? Or how could Big Bang be?
(Sorry for my bad english, and maybe...
I would say you cannot in any way find out or prove what reality is. Everything we see, touch and think about might just be some kind of illusion. The only things that you can be 100% sure of is that you exist and that mathematics are correct.
1) Check black holes on wikipedia, or continue reading my mediocre explanation of black holes. Matter attracts matter, and the bigger mass the matter has the bigger attraction it has on other matter. For example Earth attracts us with an acceleration of 9,82m/s^2. If Earth's mass would be...
Well I believe it would turn out the same every single time. It's really impossible to get exactly the same conditions, but if it would be possible, there are no reasons why it shouldn't have been the same time after time after time.
I don't know how I could explain it, but every action we...
I believe that if we rewound to the early years of universe and let it all happen again, with the same starting conditions, it would all turn out the same.
You could look into it in another perspective. If there were another planet with the exact same conditions as earth, which had the same...
I think you have to analyze different theories and judge if they're logical or not. If you find any theories which you don't believe in, try finding out yourself how it could be, then try to prove it.
You must mean Vzero + V = s / t ?
if we replace the t with v/a we get a deltav, and the delta v should be the negative of Vzero.
Because out of that I got:
( Vzero + V ) / 2 = s / ( -Vzero / a )
Vzero + V = 2s / (v / a )
-Vzero/a ( Vzero + V ) = 2s
-Vzero (Vzero+V) = 2as
-Vzero^2 - Vzero * V...
maybe we could replace the Vzero with something instead.
V = Vzero + at
-Vzero = -V + at
Vzero = V - at
Vzero = 2ta - V
V - at = 2ta - V
V = 3at - V
2V = 3at
Since V = 0 the equation would be
0 = 3at
0 = 3 * 7,856 * t
0 = 23,56t
Didn't work. :/
EDIT : Was written before your post. Will...
That would be ( Vzero + V ) / 2 :
Vzero = initial velocity
V = the final velocity
t = v/a
t = ( ( Vzero + V ) / 2 ) / a
ta = ( Vzero + V ) / 2
2ta = Vzero + V
Vzero = 2ta - V
BUT, this is 2 unknown variables ( Vzero and t ), which makes the equation uncalculable (as far as I know)...
v=s/t
maybe we could replace v with s/t in the quation
t = v/a
t = (s/t)/a
ta = s/t
t^2*a = s
t^2 = s / a
t^2 = 22 / 7,865 ( the acceleration is negative, but since you can't "root" any negative numbers i put it as a positive number, is this right or wrong? )
t^2 = 2,78
t = 1,67s
