Today, time rules our lives. We live each day with the moments broken up into hours, minutes and seconds. We never seem to have enough time. But can you imagine not being able to tell time at all, where the movements of the Sun and the stars was the only way to know what time it was? Let's learn about the history of time, methods of telling time, and Einstein's historic discovery that time isn't as fixed as we thought it was.

Thank you for the new episodes. Too bad, they were not announced where they usually were: http://feedproxy.google.com/universetoday/pYdq
I thought you guys stopped making podcasts.

Time is movement. Simply having movement defines time.

have you seen Time Warp on discovery?

this is a cool show on Discovery Channel where a team of guys capture everyday stuff on cameras with a shutter speed of 5000 frames per second then slow the event down to watchable speeds.

really neat stuff like drum sets with cymbals and drum heads, bullets slowly ripping through cans of soda and lolly pop heads and ballons and bubbles bursting.

just watching this really helps give deeper understand the physical world.

I find Time to be a topic which I just don’t get bored of but I have a question of sorts posed in a theory, but as a bumbling amateur fool with just the basic grasp of relativity and postage stamp size understanding of the quantum world most of this if not all maybe just be gibberish.


Question: is there only one force of time in the universe (space-time) or does it have a more powerful brother


Is the speed of the light really the actual the speed of light or just the max speed at which light and all other things can travel at and if so why is there a limit and what governs it?



a) If the above statement is correct then the Term the speed of light is in fact just a mental construct and just the speed limit at which LIGHT can not or anything else can pass!.

b) If we also agree that everything in the universe travels through time at the speed of light does this not show us that if these two speeds the speed at which objects pass through time equals the exact same speed as the speed which light nor anything else can move faster than within the flow general space-time there must be a direct connection between one and the other?.

c) Experiment has shown that we can slow light down but we can’t speed it up, As eloquently put by Mr Einstein even though a object may travel at the speed of light it does not effect the speed of the light leaving the object, a point here is why Einstein’s answer is correct to me is states that the speed of light relative to the speed of an objects movement through time (space time) can not change if so then is not the real speed limiter in the universe is the speed of time ?.

d) We agree that if we have two objects A and B and if B travels away from stationary A at the speed of light for a length of time and then returns A will have encountered more time than B has, but the time relative to each A & B is constant both encountered 60 seconds a minute 60 minutes an hour both travelled through time at the speed of light so how then does A experience more time? he does because the energy B used to travel at the speed of light through space-time has altered and his position in the flow of external space-time relative to his direct time, does this mean there are two forces of time one of a general flow of space time in which everything is loosely connected to like objects in a flowing stream and a relative force of direct time which each object in the universe feel relatively? .

e) We say space time is relative but it cant be it must be general and connected through out the universe in a motion of flow the fact we can take two objects and alter their position in space time to each other an analogy is if I could travel fast enough I could visit my great great great grandsons 21st birthday shows us space-time is a static flow which can be manipulated in a foward motion so the flow of general space-time is only relative to my postion and not my direct time.

f) But the fact that I can not change the rate of time I experience leads me to believe there must be a second force of time separate from space-time which is relative to me and unchangeable which can not be manipulated by the input or subtraction of energies this would happen on the quantum level and maybe why quantum physics is so strange because it is a place where a second force of time exists without space?.

g) And if at the quantum level another different force of time exists without space it would make sense of the problem of measuring things at the quantum level for instance asking a question about a particle’s location is like asking which way is up in galactic space the particle will be where ever you try to measure it, as general space-time has no effect on the quantum world as I picture it as a soup like structure with no space just particles and a force of direct time.

h) I believe that the reason I experience 60 seconds a minute 60 minutes an hour( meaning travel through time at the speed of light) is because each part of me at the quantum level is programmed by a direct force of time which cares not what happens in general space-time whether I take a holiday on a black hole or travel at the speed of light through general space-time to increase the distance I travel along it’s flow, my quantum clocking keeps ticking in direct time and I will never be able to make that 60 seconds a minute change relative to me.

i) Here is an analogy to help explain what I am trying to say: if we take space-time as a river that flows and each quantum particle is a boat with no power no oars travelling along the flowing river these particles can find ways to race ahead of each other and travel further along the flow and cover more of the river but as with all systems there is a governor in this case direct time which we will call the boat keeper , as each particle enters the river the keeper ties a line to it and gives a start time to each particle, the particles river cruise has a finite time allocated by the keeper and he also acts as a patrol man stopping particles escaping the river and misbehaving by means of his line he limits their speed so they don’t sink or take off and no matter how far the travel along the river(space-time) in relation to the boat keeper it matters not, when their allotted time is up he will pull them in so no matter what the particles do in the river (space-time) the will only ever experience there allotted time even if they find high energies to travel at speed of light through space time their hope of a longer life is just an illusion of movement through of general space-time relative to another particle..


I believe that general space-time as we it know travels in a flow in one direction forward; we can manipulate the positions of objects within it so long as it is in a forward motion.

But it still does not answer the question why I experience time at 60 seconds a minute 60 minutes an hour no matter what speed I travel at or how a manipulate my position in the flow of general space-time relative to anything else I always travel through time at the speed of light.

I just can't get my head round space-time being relative my mind has it only as a general force which flows in one direction and governs the land of the big , i also can't get rid of the idea of that there is a second more potent force of time on it’s own which is a force tied in at the quantum level that exists as a force of control on all objects at the quantum level limiting them to travel through time at the speed of light and it is this force which governs the speed light and everything else a force which can not be tampered with changed, altered , reversed or sped up and it is this force of time which truly is master of ours lifes , a force of time without space.
