Hello,
I have read that vacuum cleaner makes 70 dBa and earplugs can easily go beyond this.
The problem I have is that I can hear my neighbor's vacuum cleaner thru wall easily. But if I set my mp3 player at max (should be around 100dBa according to manufacturer) I can heard this at few...
Yes, you're right, I ment orientation - vertical & horizontal.
The graph is amazing. It perfectly shows what I wanted to see. I worked with this when visualising the speed time dilation for me, and what you draw make sense to me.
I can now imagine acceleration time dilation vertical or...
No no, I mean it as the light is released above event horizon, the "light clocks" are not in even horizon, both mirrors are slightly above it. (slightly = simply I assume the gravitation will be able to bend the light as in example on the left side.)
Thank you so much for the reply.
I think it's correct. It sounds logic.
But, this would mean the position of light clocks is also important ... while I have some sense that time dilation should be "general" - and not depending on position of clocks, let me explain...
I know, I read this many times.
The problem I have is why acceleration and gravitation cause time dilation. (I know it dilate time, I don't know why it dilate time - the "logic" of this effect is what I don't know)
The logic at speed time dilation is simple - the light in "light clock"...
Thank you for reply.
I realized this sounds bad. It sounds like I think the time is slower because it will fly more kilometres thru the "gravitation well". I ment it as it will take longer distance for the light beam inside "light clocks" to make one "cycle" inside the clocks. (while the speed...
I have better picture now:

As visible on picture the full green line is a path of ship A - traveling thru spacetime with no gravitation influence.
While second green light shows path of ship B - which travel thru space and then travel...
I were trying to figure out the "logic" why gravitation (acceleration) causes time dilation.
While at "velocity time dilation" its because (e.g) light in light clocks must travel longer distances.
As seen on those pics:

I know its valid frame of reference, not different from our's on earth.
My point is that there is ship and A to B route
Ship is one frame of reference and
A to B is also one frame of reference (they are not moving to each other)
My point is that if a ship is moving, so people on Earth...
So if there's A to B points = distance 1 light year.
A= earth
B= destination_planet
Ship travels v=0,999c, from A to B.
From ship's view of point:
The cosmonaut will not spend approx 1 year in space.
He will fly on distance of 1ly divided by the y (d=1ly/22=0,045 ly)
So the time will be t=d/v...
Ok, I think I understand.
1)
From his point of view, the B point is closing to him. Since there's a length contraction, the "his" length between ship and B is small. But how long will he travel then from his frame?
Will he think he spent 1 year in ship, or less?
2)Andd as soon as he...
Hello, I have been lately very interested in time dilation. I have found out many information about it and it's very interesting for me. But I have few problems I don't quite understand, so I will be glad for your help.
Let's start:
There's a man traveling in a spaceship from point A to...
