The fundamental constants of the Universe appear to be fine-tuned with incredible precision to allow for life. The slightest variation would make our existence impossible, raising a profound ...

It would further help the situation if the physical constants weren't so constant. It is already understood that some of the physical constants can be modified under some very high energy conditions.

In this way it becomes possible to test the values of the physical constants when the Universe had only 25% of is present age, that is, about 10,000 million years ago. Very far beacons .

He says only that a certain set of physical constants would start to favour the emergence of a new physical “structure”, which would endure if it had robust properties. “I realise that what I am ...

Cosmic alcohol, vintage seven billion years, measures physical constant Confirms the proton-electron mass ratio has been constant since. Matthew Francis - Dec 13, 2012 7:00 pm UTC.

In terms of some of the physical constants we’re more familiar with, this is a ratio of the elementary charge (of, say, an electron) squared to Planck’s constant and the speed of light.

The physical constants of the universe appear to favor the existence of life. ... The constants are the way they are because if they were different, we wouldn't be here to observe it.

Following analysis of data from two large telescopes, John Webb and his team suspect a basic physical constant, known as alpha, the Fine Structure Constant, which measures the strength of ...

Why Is 1/137 One of the Greatest Unsolved Problems. Season 8 Episode 28 | 14m 37s Video has Closed Captions | CC. The Fine Structure Constant is one the strangest numbers in all of physics.

Most "tweakings" of the physical constants, however, would render a universe stillborn. That said, some don't like the concept of the multiverse.

New Quasar Studies Keep Fundamental Physical Constant Constant Date: April 1, 2004 Source: European Southern Observatory (ESO) Summary: Detecting or constraining the possible time variations of ...

One of these constants is the so-called "fine structure constant", alpha = 1/137.03599958, a combination of electrical charge of the electron, the Planck constant and the speed of light.
