Default LEE SMOLIN AGAINST EINSTEIN AND NEWTON

Smolin defends Newton against Einstein:

http://www.fqxi.org/community/articles/display/148
"Many physicists argue that time is an illusion. Lee Smolin begs to differ. (...) Smolin wishes to hold on to the reality of time. But to do so, he must overcome a major hurdle: General and special relativity seem to imply the opposite. In the classical Newtonian view, physics operated according to the ticking of an invisible universal clock. But Einstein threw out that master clock when, in his theory of special relativity, he argued that no two events are truly simultaneous unless they are causally related. If simultaneity - the notion of "now" - is relative, the universal clock must be a fiction, and time itself a proxy for the movement and change of objects in the universe. Time is literally written out of the equation. Although he has spent much of his career exploring the facets of a "timeless" universe, Smolin has become convinced that this is "deeply wrong," he says. He now believes that time is more than just a useful approximation, that it is as real as our guts tell us it is - more real, in fact, than space itself. The notion of a "real and global time" is the starting hypothesis for Smolin's new work, which he will undertake this year with two graduate students supported by a $47,500 grant from FQXi."

Smolin attacks both Newton and Einstein:

"Time Reborn: From the Crisis in Physics to the Future of the Universe, by Lee Smolin (...) A distinguished physicist delivers a thoughtful, complex re-evaluation of the role of time in the universe. Smolin (The Trouble with Physics: The Rise of String Theory, the Fall of a Science, and What Comes Next, 2006) points out that no one doubts that space is real. If the cosmos were empty, space would exist, but there would be no time. So time is inextricably bound up with the material universe, a real phenomenon at the heart of nature. This turns out to be controversial since the great thinkers from Plato to Newton to Einstein taught that time is an illusion that humans must transcend to achieve true understanding. Smolin disagrees, maintaining that embracing its reality is the key to solving the great problems in physics."

Lee Smolin,

Newton and Einstein cannot be equally wrong. For instance, Einstein says that the travelling twin returns younger while Newton would reject that with contempt. Who's right? Thibault Damour elaborates on Einstein's position and explains that "a sentient being can jump, within a minute (of his experienced time), arbitrarily far in the future, say sixty million years ahead, and see, and be part of, what (will) happen then on Earth". Do you agree with Thibault Damour, Lee Smolin?

http://www.bourbaphy.fr/damourtemps.pdf
Thibault Damour: "The paradigm of the special relativistic upheaval of the usual concept of time is the twin paradox. Let us emphasize that this striking example of time dilation proves that time travel (towards the future) is possible. As a gedanken experiment (if we neglect practicalities such as the technology needed for reaching velocities comparable to the velocity of light, the cost of the fuel and the capacity of the traveller to sustain high accelerations), it shows that a sentient being can jump, "within a minute" (of his experienced time) arbitrarily far in the future, say sixty million years ahead, and see, and be part of, what (will) happen then on Earth. This is a clear way of realizing that the future "already exists" (as we can experience it "in a minute")."

Default LEE SMOLIN AGAINST EINSTEIN AND NEWTON

Lee Smolin criticizes Newton's theory and glorifies Einstein's theory: According to the former, gravity does not bend light; fortunately Divine Albert informed mankind that gravity does bend light:

Lee Smolin, 66:12: "Newton's theory predicts that light goes in straight lines and therefore if the star passes behind the sun, we can't see it. Einstein's theory predicts that light is bent...."

"What is time? Is our perception of time passing an illusion which hides a deeper, timeless reality? Or is it real, indeed, the most real aspect of our experience of the world? Einstein said that, "the distinction between past, present, and future is only a stubbornly persistent illusion," and many contemporary theorists agree that time emerges from a more fundamental timeless quantum universe. But in recent cosmological speculation, this timeless picture of nature seems to have reached a dead end, populated by infinite numbers of imagined unobservable universes. In this talk, Lee Smolin explains why he changed his mind about the nature of time. Like many fellow theorists, he used to believe time is an illusion, but he now embraces the view that time is real..."

The consequences of Einstein's 1905 false light postulate are "deeply wrong" and have reached a dead end? Sic transit gloria mundi:
