The physicist and author argues that cosmologists should take the concept of time more seriously and talks about becoming a “converted skeptic” on climate change.
....MULLER: The flow of time does not exist in the usual spacetime diagram of physics. Time is mysterious; in any relativistic coordinate system, it is linked to space. And yet time is different—and I mean much more than simply a sign in the metric. Time flows. Choose any coordinate system and you can stand still in space but not in time. That different behavior breaks the otherwise glorious spacetime symmetry. Moreover, there is a special moment in time we call “now.” No such special location exists in the dimensions of space.
Einstein considered his inability to account for the flow of time and the meaning of “now” as a failure. Some modern theorists aren’t up to his standard; they think that anything they can’t explain with their current theories must be dismissed as illusionary.

Assuming you’re incorporeal, your location at any given time is quite absolute, to you. You have no choice in that coordinate system.
Assuming you’re not incorporeal, correction.
What "coordinate system"? There are a near infinite number of them.
(incorporeal: not composed of matter; having no material existence)
Moreover, there is a special moment in time we call “now.” No such special location exists in the dimensions of space.
Uh, how about “here?”
LMAO!
Your personal coordinate system can be none other than self-centered. At base, you have no other perspective and no choice in the matter, so long as you inhabit matter. Here is where self is at any given now.
That’s exactly what I thought.
I would also think, contrary to Baldwin’s comments, that you can’t stand still in space due to the expansion of the universe.
It was oddly geocentric thing to say, wasn't it?
I mean Muller.
The real purpose of this article is to convey the message quoted below. I believe this is why they don’t seem to be thinking carefully about space and time.
“We came up with a solid analysis of each of the biases and were able to conclude, using our independent work, that global warming was real and caused by humans.”
Does anybody really know what time it is?
Does anybody really care?
(Except maybe the pretty lady that asked me what time was on my watch).
I think they have a very different underlying agenda, as stated in post # 50.
The formula goes like this: talk about physics, sound authoritative (which didn’t work here), then let loose with the propaganda.
Here’s where the guy makes the move to establish his credibility:
“Einstein considered his inability to account for the flow of time and the meaning of “now” as a failure. Some modern theorists aren’t up to his standard...”
The article’s entire message can be summarized as follows:
“Think of me as Albert Einstein. Global Warming is real and caused by humans.”
Your personal coordinate system?
All that can do is describe where various parts of you are located on your body. (0,0) can be your belly button. :)
But that example deals entirely with SPACE, not time.
Velocity is DEPENDENT on time. So I suppose in the sense that velocity represents distance over time, and distance is space, then the two can be considered related. But how does one define time in terms of distance/space?
timetraveler
Lambda (Einsteins famous relationship for a mass at rest vs at a speed v) doesn't have time in it — only C (speed of light) and v (current speed).
This relationship can be used to determine time dilation and mass dilation.
Of course, velocity is distance vs time so time is implicitly defined in the equation.
