We Know More About Time Than You Think
Sir Isaac Newton claimed time flows universally. Albert Einstein said that time is relative to the observer. Theoretical physicist Professor Brian Greene rejoins WIRED to break down the emerging theories that tell us everything we know about time; from the impact of speed (special relativity) and gravity (general relativity) on time dilation to the role…

What’s happened, happened. Which is an expression of faith in the mechanics of the world. It’s not an excuse to do nothing.

11:48 So measuring time is measuring how disorganised the room is compared to another point in time?

He was in Epstein files. Stop giving him platform.

I’m not sure that the light moves, bruh.
The source of the light could move but the light itself doesn’t.
It is exist (appear) and (inexist) dissapear, without impacted by the distance.
The ‘range of the light’ depends on its power (energy).
That’s my opinion.

He has no idea, I wouldn’t give him a second thought.

How do you make this video sound less like it was researched by a group of students who didn’t care about their grade in physics class?

2 seconds; everybody exists in the *NOW* but by the time a word has left your mouth to a recipient, 3 seconds has elapsed
Enough time to formulate a joke about their dumb comment, and enough time for them to no longer be in the vicinity to hear it

The Stuff-side of the Eternal Life, is a Motion-Ocean,
Time is the ‘Shadow’ of Motion, Stuff-side,
Time do Only exist in the Consciousness of Living Beings.
Forget about Newton, Einstein, and Brian Greene.
Every child knows what Time-Space is, ”space-time”, is Doomed,
because it give NO meaning.
”Time Dilation”, is another Dead mantra, there is NO time dilation.

Everytime I see light it is stationary, unless shifted by a shadow casted by a moving object…

Thank you Dr. Who! I think that I agree, lol.

Still there’s no time in space and on earth, and no one can prove it’s existence

I think time is manipulated like ripples in a pond; something that will affect the future will affect the past.
My believe that time travel works like a loop that occurs countless quadrillions of times, and every line carries an infinitesimal change. After a certain number of rotations, that change can cause the loop to change itself. This explains the grandfather paradox, where you can kill him and still go back, to alter your creation. I also believe the universe will naturally auto-correct changes to the fabric of time to prevent total collapse.
Just because Kyle Reese was sent back in time doesn’t mean he was John Conner’s original Father; maybe Kyle’s son just took on the role, carrying a different loop.

Hmmm, not being a scientist I’m in the dark here. Everything that you explained, to me, is a representation of time, not actual time. Time is not an object or a sentient bring but an ethereal thing with no actual body. If time stops, as in your black hole theory, then it would seem that the person would not exist at that moment. The measurements of time may cease but time itself carries on in spite of that unless everything ends at that moment. Please elucidate.

hard to believe anyone who tries to force a BS theory like string theory
if you have 3 apples and it requires 9 for a pie… pretending you have 9 and saying, “we have PIE” is kinda insane it doesnt matter that apples + crust = pie…. apparently numbers matter in physics, who knew?

Here are 2 ships passing each other.
Ship1 at rest at top.
10;00 10;00
T——————–N
<--- N----------T 10;00 10;02 Ship2 at rest at bottom. 10;00 09;58 T----------N --->
N——————–T
10;00 10;00
Are the 2 ships passing each other once or twice?
T1 passes N2 twice. T1 passes N2 when the clock at N1 reads 9;58. T1 passes N2 again when the clock at N1 reads 10;00. If T1 meets N2 once then what is the time displayed at N1 when this happens?

I think time is a result of movement through space like how charge is electrons moving through a magnetic field. If u could stop all your motion in relation to space time would stop. You cannot reverse time because you cannot reverse your motion in space. you just change direction.

We are always time-traveling backwards and forwards in time. It’s just that we can’t remember doing so because the neurons and chemical reactions in our brains are also moving backwards and forwards in time
