Inspired
by Gene Roddenberry’s Star Trek, physicist Miguel Alcubierre set out to
transform one of the cornerstones of science fiction iconography, the
Warp Drive, into reality. But is it even possible? Can we "warp" the
fabric of reality so that we can break the speed of light? And why is
NASA actually exploring this potentiality? Join Matt on this week’s
episode to learn the physics of what's physically possible!

New Research Collaboration Explores Microbiome of the Space Station
https://www.nasa.gov/feature/new-rese...
“More
than 200 people have crossed the airlock threshold to the International
Space Station to conduct research that benefits people on Earth and the
agency’s Journey to Mars. The microbes they brought with them—and left
behind—are the focus of a new collaborative research opportunity from
NASA and the non-profit Alfred P. Sloan Foundation.”

How does ultraviolet light kill cells?
https://www.scientificamerican.com/ar...
“Ultraviolet
(UV) light kills cells by damaging their DNA. The light initiates a
reaction between two molecules of thymine, one of the bases that make up
DNA. The resulting thymine dimer is very stable, but repair of this
kind of DNA damage--usually by excising or removing the two bases and
filling in the gaps with new nucleotides--is fairly efficient.”

Science Documentary: Big Bang, Inflation, Multiverse, a Documentary on Cosmology

The Big Bang happened 13.7 billion years ago, but we do not know
what
or why it happened. So far we can only speculate, but we do know that
the Big Bang gave us all the ingredients that make up our universe. All
the energy and matter that exists in our universe was created during
the Big Bang.

Cosmology is the study of the origin of the
universe and the way in which it evolves over time. Since the speed of
light is a constant, this helps us to study the universe. When we look
at stars and galaxies through a telescope, we can determine their age by
measuring the time it takes for their light to reach our eyes. This
measurement of time is light years.

Studying cosmology has
provided us a concise picture of the universe from its origin in the Big
Bang all the way up to today. But there are several questions that we
have yet been able to answer. The first question asked is whether there
was anything before the Big Bang. Did space and time exist prior?
Another question is what is Dark matter. Dark matter is abundant in the
universe. In fact, there is more Dark matter than regular matter in
the universe. Dark matter interacts with gravity but not with light.

When
scientists observe the expansion of the universe, they observe that the
expansion was accelerating. This means that the galaxies were flying
away from each other faster and faster. It is believed that the cause
of this acceleration is due to Dark Energy.

Perhaps the biggest
question is whether there is life somewhere else in the universe. Our
technology to this point has not allowed us to discover life on other
planets, but over the next several decades, scientists believe that this
question may be answered.

Is our universe part of a multiverse?
The standard Big Bang theory suggests that the universe began roughly
13.7 billion years ago from an incredibly hot dense state referred to as
a singularity. But Inflationary theory suggests that the Big Bang was
not the beginning of existence , but it was our own local Big Bang in a
much greater multiverse which already existed.

The standard Big
Bang theory does not describe what banged or why. It merely describes
the aftermath of the bang. This means that the explosion of the Big
Bang had already occurred before the theory begins.

Inflation
is a theory that modifies the Big Bang theory, but is not intended to
replace it. Although the Big Bang theory is a truly successful theory;
inflation is the "bang" portion of the Big Bang theory.

Conformal Cyclic Cosmology

Conformal Cyclic Cosmology

Δημοσιεύτηκε στις 26 Οκτ 2016

Please check out these links before watching the video
https://www.youtube.com/user/skydivephil
By https://plus.google.com/u/1/116782372...

The
conformal cyclic cosmology (CCC) is a cosmological model in the
framework of general relativity, advanced by the theoretical physicists
Roger Penrose and Vahe Gurzadyan. In CCC, the universe iterates through
infinite cycles, with the future timelike infinity of each previous
iteration being identified with the Big Bang singularity of the next.
Penrose popularized this theory in his 2010 book Cycles of Time: An
Extraordinary New View of the Universe.

The Uncertainty Principle Documentary

The Uncertainty Principle Documentary

Δημοσιεύτηκε στις 16 Οκτ 2016

Heisenberg's
Uncertainty Principle states that it is impossible to know both the
exact position and the exact velocity of an object at the same time.
However, the effect is tiny and so is only noticeable on a subatomic
scale.

Werner Heisenberg (1901-1976) was a German physicist who
helped to formulate quantum mechanics at the beginning of the 20th
century. He first presented the Heisenberg Uncertainty Principle in
February 1927 in a letter to Wolfgang Pauli, then published it later
that year.

Light can be considered as being made up of packets of
energy called photons. To measure the position and velocity of any
particle, you would first shine a light on it, then detect the
reflection. On a macroscopic scale, the effect of photons on an object
is insignificant. Unfortunately, on subatomic scales, the photons that
hit the subatomic particle will cause it to move significantly, so
although the position has been measured accurately, the velocity of the
particle will have been altered.

By learning the position, you
have rendered any information you previously had on the velocity
useless. In other words, the observer affects the observed.

Project Starshot: Visiting the Nearest Star Within Our Lifetime

Ζωντανή μετάδοση στις 1 Δεκ 2016

The
nearest star to the Sun, Proxima, was discovered this year to host an
Earth mass planet in its habitable zone. Proxima is only 4.24 light
years away. Can a camera fly by this planet to find out whether there is
life on it? Starshot is a new project aimed to develop the technology
that will enable to launch a spacecraft at a fifth of the speed of
light, so that it will reach Proxima within our generation. The concept
is based on a high power (100GW scale) laser beam pushing a lightweight
(gram scale) sail, attached to a chip containing a miniaturized camera,
communication and navigation devices. The feasibility study phase of the
project had just started at a funding level of $100M for the next 5-10
years, with CfA participation.

Over
the last three years ICTS has been organizing successful summer/winter
schools on various topics of gravitational-wave (GW) physics and
astronomy. Each school from this series aimed at focussing on a
particular sub-area (theory, experiment, data science, etc) of GW
science. This year, the organization of such a school assumes a special
significance: The first direct detection of GWs by the LIGO
observatories has been announced on 11 Feb 2016. This confirms a major
prediction of Albert Einstein’s general theory of relativity and opens a
fundamentally new observational window onto the Universe.

This
year’s school will involve three graduate-level courses in theoretical
GW physics. The lectures will be given by three world leading experts
-- Clifford M Will (University of Florida), B. S. Sathyaprakash (Penn
State University / Cardiff University), Emanuele Berti (University of
Mississippi and Instituto Superior Técnico, Lisbon).

It
is the biggest of problems, it is the smallest of problems. At present
physicists have two separate rulebooks explaining how nature works.
There is general relativity, which beautifully accounts for gravity and
all of the things it dominates: orbiting planets, colliding galaxies,
the dynamics of the expanding universe as a whole. That’s big. Then
there is quantum mechanics, which handles the other three forces –
electromagnetism and the two nuclear forces. Quantum theory is extremely
adept at describing what happens when a uranium atom decays, or when
individual particles of light hit a solar cell. That’s small.

Now
for the problem: relativity and quantum mechanics are fundamentally
different theories that have different formulations. It is not just a
matter of scientific terminology; it is a clash of genuinely
incompatible descriptions of reality.

The conflict between the
two halves of physics has been brewing for more than a century – sparked
by a pair of 1905 papers by Einstein, one outlining relativity and the
other introducing the quantum – but recently it has entered an
intriguing, unpredictable new phase. Two notable physicists have staked
out extreme positions in their camps, conducting experiments that could
finally settle which approach is paramount.

Basically you can
think of the division between the relativity and quantum systems as
“smooth” versus “chunky”. In general relativity, events are continuous
and deterministic, meaning that every cause matches up to a specific,
local effect. In quantum mechanics, events produced by the interaction
of subatomic particles happen in jumps (yes, quantum leaps), with
probabilistic rather than definite outcomes. Quantum rules allow
connections forbidden by classical physics. This was demonstrated in a
much-discussed recent experiment in which Dutch researchers defied the
local effect. They showed that two particles – in this case, electrons –
could influence each other instantly, even though they were a mile
apart. When you try to interpret smooth relativistic laws in a chunky
quantum style, or vice versa, things go dreadfully wrong.

Relativity
gives nonsensical answers when you try to scale it down to quantum
size, eventually descending to infinite values in its description of
gravity. Likewise, quantum mechanics runs into serious trouble when you
blow it up to cosmic dimensions. Quantum fields carry a certain amount
of energy, even in seemingly empty space, and the amount of energy gets
bigger as the fields get bigger. According to Einstein, energy and mass
are equivalent (that’s the message of E=mc2), so piling up energy is
exactly like piling up mass. Go big enough, and the amount of energy in
the quantum fields becomes so great that it creates a black hole that
causes the universe to fold in on itself. Oops.

Hogan, a theoretical astrophysicist at the University of Chicago and
the director of the Center for Particle Astrophysics at Fermilab, is
reinterpreting the quantum side with a novel theory in which the quantum
units of space itself might be large enough to be studied directly.
Meanwhile, Lee Smolin, a founding member of the Perimeter Institute for
Theoretical Physics in Waterloo, Canada, is seeking to push physics
forward by returning to Einstein’s philosophical roots and extending
them in an exciting direction.

To understand
what is at stake, look back at the precedents. When Einstein unveiled
general relativity, he not only superseded Isaac Newton’s theory of
gravity; he also unleashed a new way of looking at physics that led to
the modern conception of the Big Bang and black holes, not to mention
atomic bombs and the time adjustments essential to your phone’s GPS.
Likewise, quantum mechanics did much more than reformulate James Clerk
Maxwell’s textbook equations of electricity, magnetism and light. It
provided the conceptual tools for the Large Hadron Collider, solar
cells, all of modern microelectronics.

What emerges from the
dust-up could be nothing less than a third revolution in modern physics,
with staggering implications. It could tell us where the laws of nature
came from, and whether the cosmos is built on uncertainty or whether it
is fundamentally deterministic, with every event linked definitively to
a cause.

Dancing in the Dark The End of Physics - BBC Documentary 2015

Scientists
genuinely don't know what most of our universe is made of. The atoms
we're made from only make up four per cent. The rest is dark matter and
dark energy (for 'dark', read 'don't know'). The Large Hadron Collider
at CERN has been upgraded. When it's switched on in March 2015, its
collisions will have twice the energy they did before. The hope is that
scientists will discover the identity of dark matter in the debris.

The stakes are high - because if dark matter fails to show itself, it might mean that physics itself needs a rethink.
