You know...starting to build our own theories. Starting to use all the knowledge we gathered, etc.

And the universe? I mean, it almost takes a lifetime to even understand what is already known. When do we start to exploring it our way?

I am 30. I am right in the middle of my lifetime, more or less. And I wonder if half a life is enough to grasp Physics by the horns and learn all about nature? I totally love physics, the beauty and mystery that the universe truly is. I actually feel empty without reading or seeing something...

I think I know what you mean now...was thinking the same thing...but since I am not well-versed with Physics terms, I couldn't express myself right..thanks!

The black clock belongs to Adam and the red one shown here, belongs to Sarah, i.e the Earth clock, in other words, the "second light clock". The time according to this, red, EARTH clock, is what is worrying me. The super above says "slow" whereas it should be "fast". If you still think I am not...

Man..sorry, but you are just repeating that. I need to know how? and why? I think we have already agreed to disagree on the EARTH clock being slower. But I need an explanation. I am sorry, but I am not quite convinced by your explanation.

Ok then tell me what's wrong in this: Adam- Space Sarah- Ground Beam of light shone from the spaceship according to the person on EARTH - Takes a longer time for the light to reach the spaceship back due to a V shape according to the person on the SPACESHIP - Takes a shorter while for the...

I don't agree then. Because my calculation tells me Adam should see Sarah's clock going FASTER and not SLOWER. Because again, Sarah's clock RELATIVE TO Adam's clock, took longer. Which means her clock is faster compared to Adam's clock which took a shorter time.

I just shared the screenshot above...That's the crux of the problem...I can understand everything, except that bit. It doesn't show the clock, but it DOES show that the time on Sarah's clock is SLOWER as compared to Adam. Which I don't think is right. Adam should see EARTH clock FASTER. Right...

Ok, but can we talk only in terms of this example..this video particularly? I want to understand this, but this is the only point I am not able to understand.

Nope. Didn't get it. For me, it's pretty simple. This is how I break it down: less time passed = slower clock more time = faster clock So, according to Adam, the EARTH clock SHOULD be fast and not slow.

From 2:58 to 5:55.

That's opposite of what the video says: The video says, the person on Earth will see that the beam takes longer to bounce back to the ship. The Person the spacecraft sees it come quicker. Hence, MORE time has ticked off on the clock on EARTH (takes longer for the beam?) and LESS time on the...

This is exactly what I don't understand. How can it be slow for the person in the spacecraft ? Shouldn't it be FAST because less time passed = slower clock more time = faster clock Or am I missing something?

Ok, I went through a video to understand it more simply. But there is one point I just don't understand. Which is this: How does Adam think others' clock is SLOW? Shouldn't it be FAST? Here's my breakdown of the video: Adam is in- Space Sarah is on - Ground Beam of light shone from the...
