Our universe is WEIRD and as they say in this great video, our intuition about how the world works is not a very good tool to understand how the world truly works!
Sorry, I call BS on "spacetime" - I say space and time are independent.
@TheMiddleWay GPS uses time dilation to be more precise. This essentially factors in gravity on their equipment. However time itself does not slow down - it is independent from gravity.
@TheMiddleWay It means that but what really happens is the mechanical devices used to measure time are slowed - time itself doesn't slow down
@TheMiddleWay Clocks are an attempt to measure time - gravity has an effect on clocks - but not on time. Time moves at a constant rate throughout the Universe. There's no getting around that. I call BS on Wormholes too. Time is one thing - space is another. And the shortest distance between two points is still a straight line.
@TheMiddleWay time - the infinite continued progress of existence. Some theorist try to tie to space, so their time travel and wormhole theories become plausible. Its all BS - we will never have time travel or wormholes.
@TheMiddleWay It has not been proven, only in theory IF the theory is accurate - which it isn't.
@TheMiddleWay Gravity can bend light and slow clocks - it has no effect on time.
@TheMiddleWay A clock is not time, gravity has an effect on clocks, not on time.
@TheMiddleWay Sure - with a sundial, or do you consider that a clock?
@TheMiddleWay Clock -a mechanical or electrical device for measuring time, indicating hours, minutes, and sometimes seconds.
Looks like a sundial doesn't qualify, its not exactly a mechanical device - a stick in the ground is a sundial.
@TheMiddleWay Relativity is a theory - not a law.
I think you are confusing time with "measured time"
Gravity effects clocks attempt to measure time - Time dilation
@TheMiddleWay You don't seem to get it - Time does not slow down - Clocks slow down.
I guess not everybody here understands the core principles of agnostic.com:
"The following are core principles* we agree with:
@verifiabliss Actually Einstein theorized about spacetime - he was correct that gravity effects our attempts to measure time. But a clock is not time. Time does not slow down. This is a simple concept that seems to evade many.
@TheMiddleWay Wrong again - Time has always existed. Clocks are an attempt to measure time.
Gravity effects clocks.
Gravity does not effect time.
Lets say you can see a planet with a large gravitational field. And theres a clock on the surface, running slower than ones on earth. Would it be more accurate to say " Time on that planet is slower than ours" or "The clock on that planet is running slower than ours"?
@TheMiddleWay A. I know time has always existed, not because of a clock, but because the Universe has always existed.
B. A clock is a mechanical attempt to measure time. Studies prove that gravity effects mechanical devices;
C. Tell time without a clock? I don't know - is that a riddle?
@TheMiddleWay A -The Universe has always been here, the Big Bang took place about 14 billion years ago.
B - Logic
@TheMiddleWay The Universe - infinite space and time.
b) The Observable universe - 14.5 billion years old, approx. 90 billion light years across.
@TheMiddleWay No - that's when the BB occurred
