Is the Universe Fine Tuned for Life?

Monday, June 14th, 2010

In short, NO. Do we need to invoke an intelligent designer to explain why the natural forces are the way they are? NO. Science is still researching how the laws of physics are determined, but everything that we know today tells us its not the universe that is fine-tuned for life, but life, through evolution, that has fine-tuned itself for the universe.

Why do I spend time debunking these absurd creationist arguments? My goal is to produce a series of videos that attacks the problem of ignorance from two angles: 1) Tell people what science actually says, how science works, what we know and are still figuring out; 2) Tell people why each of the creationist arguments are wrong, thereby not ignoring their claims and seeming to hide from them. Also, its so easy, its fun.

Heres how the calculation was done. Total volume = volume of the Milkyway galaxy (radius = Milkyway to Andromeda galaxy / 2) so the volume = 6.88e66 cubic meters. The volume of the habitable space on earth (-2000m to +8000m) = 5e18 cubic meters. Assume 1e11 habitable worlds per volume like the Milkyway. Total habitable volume (5e29 cubic meters) per unit volume (6.88e66 cubic meters) gives 7.3e-38 universe is habitable.

Universe

Thursday, June 10th, 2010

Is it possible for distant galaxies to be moving away from us faster than the speed of light?

And if it is would it be possible for us to see them?

Surprisingly the answer to both questions is a resounding YES.

How is that possible? How can something travel faster than the speed of light?

Today we will try and paint an accurate picture of the universe based on the Lambda-Cold-Dark-Matter model, which is the best cosmological model today.

Once we have painted that picture, the answers to our questions will be straightforward.

Universe : 1/14 : Beyond Big Bang : 1/7 : Copernicus

Monday, May 24th, 2010

The History Channel
Australia & New Zealand

The Universe : 1/14
Beyond The Big Bang : 1/7
Copernicus

Learn about Copernicus’ theories of a sun-centered universe.

It all began inside a violent, blinding explosion that threw everything into chaos. Ever since, our greatest thinkers have peered into that chaos in search of order, logic & the answers to where we began.

As earlier generations learned to decipher the cosmic clues of how we came to be, we stepped from revelation to revelation; epiphany to epiphany.

Aristotle told us the world was round. Ptolemy conceived of a system of planets, stars & sun.
Copernicus placed the sun at the center of this system.
Galileo confirmed it.
Newton explained what held it all together. Einstein offered insight into what fueled it.
Hubble proposed it started with a “Big Bang”.

Our search for answers has shaped how we have evolved as thinking creatures.
The Big Bang is the history of why & how we think about who & what we are.

We’ll contemplate how various cultures believe the world began & how it will all end…& what comes after.
& for the first time, we’ll be able to see what it might have all looked like, sitting in God’s front row seats.

Using unprecedented cutting edge animation, The Big Bang will recreate that amazing moment when everything started.
With interviews from the world’s leading physicists, engineers & historians we will employ every storytelling tool to make complex & confusing ideas clear, exciting & dramatic.
Recreations, visual metaphors & first-person accounts will explain concepts like: the formation of galaxies, the existence of other dimensions & the idea of a parallel universe.

The Big Bang will pose one of history’s greatest questions, Where do we begin?

Runtime: 00:58:56

There’s something very odd going on in space, something that shouldn’t be possible. It is as though vast swathes of the universe are being hoovered up by a gigantic and invisible celestial vacuum cleaner.

Sasha Kaslinsky, the scientist who discovered the phenomenon, is understandably nervous: ‘It left us quite unsettled and jittery,’ he says, ‘because this is not something we planned to find.’ The accidental discovery of what is ominously being called ‘dark flow’ not only has implications for the destinies of large numbers of galaxies but threatens to overturn our current understanding of the birth and evolution of the universe.

Does dark flow herald a new era of cosmological understanding, or does it simply mean that everything we know about the universe is wrong?

Another brilliant documentary from the BBC’s ‘Horizon’ series.

Carl Sagan – God, the Universe, & Everything Else

Sunday, April 11th, 2010

Stephen Hawking – God, the Universe, & Everything Else / Carl Sagan, Arthur C. Clarke (1988)
British journalist and TV host Magnus Magnusson tackles big questions about our universe in this educational colloquium that brings together three of the 20th century’s leading scientific thinkers: theoretical physicist Stephen Hawking, astronomer Carl Sagan and author Arthur C. Clarke. They explore everything from the Big Bang Theory to the expansion of the universe, black holes, extraterrestrial life and the origins of creativity.

Coast to Coast AM – Mar 26 2010 – Consciousness & the Universe part 1/9

Tuesday, March 30th, 2010

PLAYLIST: http://www.youtube.com/view_play_list?p=54FCCA59399F6B0B
Filling in for George Noory, Art Bell welcomed renegade thinker and scientist, Robert Lanza, who discussed how life and consciousness are essential to the existence of our universe — a
controversial theory called “biocentrism”. Numerous experiments show that everything we see out there, every single particle, depends on the presence of an observer, he said.

Citing the two-hole experiment, in which particles are beamed toward a barrier with double slits, Lanza pointed out that an observed particle acts as one would expect and goes through a single
hole. When unobserved, however, the particle behaves like a wave and passes through multiple slits at the same time. Lanza suggested that our observations effect the world around us as well, and
without conscious observers (in the form of biological life) there would be no universe at all.

space and time are not external objects and do not exist independent of an observer’s mind, he continued. Lanza likened time to a vinyl record on a turntable. All of the songs exist simultaneously
even if you only experience them one at a time. He further proposed that the choices we make in our present can effect the past, noting the conclusions of a recently published experiment in which
scientists retroactively changed a quantum event that had already happened.

This theory of time may dramatically alter our understanding of what we think are linear-based events, such the Big Bang. According to Lanza, without a consciousness there to observe it, the Big
Bang exists only as a probability state. As an example, he referenced the work of late physicist John Wheeler, who advanced the notion that light from distant quasars only existed when it was
observed.

Lanza also spoke briefly about human cloning and stem cell research.

What Hubble Taught Us About The Planets

Sunday, February 14th, 2010

Hubblecast 27: What Hubble Taught Us About The Planets.

For nineteen years, NASA/ESA’s Hubble Space Telescope has made some of the most dramatic discoveries in the history of astronomy but it has also helped scientists learn more about our own Solar System. From its vantage point 600 km above the Earth, Hubble has studied every planet in our Solar System except Mercury where light from the Sun would damage its instruments.

Hubble has captured the impact of a comet on Jupiter, immense storms on Neptune and even tiny dwarf planets at the edge of our Solar System. The veteran telescope keeps a watchful eye on our solar backyard.

Regarded by many as the most valuable astronomical tool, the Hubble Space Telescope is approaching its 19th anniversary in space. Hubble sees into the far reaches of the Universe but its powerful instruments have also surveyed our planetary neighbours. In this episode, well see what Hubble has revealed to us in our own solar backyard.

Even those who, for some strange reason, arent astronomy enthusiasts are likely to recognise some of Hubbles most famous images, like the “Pillars of Creation”in the Eagle Nebula or the Hubble Deep, and Ultra Deep, Fields which have shown us some of the most distant galaxies ever observed. The Hubble Space Telescope has really fundamentally changed our understanding of the universe at large, but with its high resolution images of planets and moons in our own Solar System, it has also taught us a lot about our own cosmic neighbourhood.

Hubble cannot observe our Sun, or the closest planet, Mercury, because its instruments are light-sensitive and would be damaged. However, the telescope has examined every other planet in the solar system, including dwarf planets Pluto, Ceres and Eris. But, of course, Hubble does not just produce pretty pictures, it provides planetary scientists with vital information about our neighbours that may help us better understand our own home planet, Earth.
