Good day, everybody. And welcome to the Astronomy Daily Podcast
00:00:03
for the first of September 2023. My name is Tim Gibbs and I will
00:00:09
be your host for today's episode. Now, as usual, I have
00:00:13
my digital A I assistant Hay here in the studio with me. How
00:00:19
many days the podcast with your host K Gibbs?
00:00:24
Now, Hay, have you got any interesting stories for us this
00:00:28
week?
00:00:28
I do indeed, Tim, one of them is a biggie. So hold on to your
00:00:32
hat.
00:00:32
Oh, intriguing. So back to you Hay for your stories of the
00:00:36
week.
00:00:38
A rare blue supermoon, the closest full moon of the year
00:00:41
dazzled Stargazers. Wednesday night, Saturn joined the
00:00:45
celestial spectacle visible alongside the moon at least
00:00:48
where skies were clear. It was the second full moon of August.
00:00:52
Thus the blue label and it was unusually close to Earth.
00:00:56
Therefore, a supermoon, the moon appeared to be bigger and
00:01:00
brighter than usual. Given its close proximity to Earth, just
00:01:03
222 miles, 357 kilometers or so. The August 1st
00:01:11
supermoon was more than 100 miles, 160 kilometers farther
00:01:16
away. If you missed it, it will be a long wait.
00:01:19
The next blue supermoon isn't until 2037 but another regular
00:01:24
supermoon is on the horizon at the end of September, the last
00:01:27
one of the year, Isaac Newton described his theory of gravity
00:01:32
as a force that acts instantaneously across space. A
00:01:35
planet immediately senses the effects of another astronomical
00:01:38
object regardless of the separation between them.
00:01:41
This aspect inspired Einstein to create the renowned theory of
00:01:45
general relativity where gravity becomes a local deformation of
00:01:48
spacetime. The principle of locality states that an object
00:01:52
is directly influenced only by its surrounding environment.
00:01:55
Distant objects cannot communicate instantaneously only
00:01:58
what is here right now matters. However, in the past century,
00:02:02
with the birth and development of quantum mechanics, physicists
00:02:06
discovered that nonlocal phenomena not only exist but are
00:02:09
fundamental to understanding the nature of reality.
00:02:12
Now, a new study from CSA Escola International Superior D ST
00:02:16
Avanza recently published in the Astrophysical Journal suggests
00:02:20
that dark matter, one of the most mysterious components of
00:02:23
the universe interacts with gravity in a nonlocal way.
00:02:27
According to the authors, Ph D students, Francesco Bonetti and
00:02:31
Giovanni Gondo along with their supervisor, Andrea Lappy. This
00:02:34
discovery could provide a fresh perspective on the still unclear
00:02:37
nature of dark matter. Dark matter is a fundamental
00:02:41
component of nature.
00:02:42
It is responsible for the formation of the structures we
00:02:45
observe in the universe today and surrounds luminous matter in
00:02:47
Galaxies contributing to the motion of the stars we see in
00:02:50
the sky. However, the nature of dark matter, especially its
00:02:55
interaction with gravity in smaller Galaxies remains
00:02:58
mysterious.
00:03:00
In recent decades, the scientific community has made
00:03:03
great efforts to understand these enigmatic phenomena. But
00:03:06
many questions remain unanswered to explore the nature of dark
00:03:10
matter and its interaction with gravity. A new approach may be
00:03:13
necessary explain the authors of the study. The new research from
00:03:17
CSA has precisely explored this intriguing path.
00:03:21
The study proposes a new model of non local interaction between
00:03:24
the dark matter of a Galaxy and gravity. It's as if all the
00:03:27
matter in the universe tells the dark matter in a Galaxy how to
00:03:30
move state.
00:03:31
The authors to model this non locality fractional calculus has
00:03:35
been employed a mathematical tool first developed in the 17th
00:03:39
century and recently found applications in various areas of
00:03:42
physics. The power of this calculus had never been tested
00:03:46
in astrophysics before we wondered if fractional calculus
00:03:50
could be the key to understanding the mysterious
00:03:52
nature of dark matter and its interaction with gravity.
00:03:55
And surprisingly experimental results on thousands of Galaxies
00:03:59
of different types have shown that the new model more
00:04:01
accurately describes the motion of stars compared to the
00:04:03
standard theory of gravity. Explain the authors.
00:04:07
This non locality appears to emerge as a collective behavior
00:04:10
of dark matter particles within a confined system proving
00:04:13
particularly relevant in small sized Galaxies, a thorough
00:04:17
understanding of this phenomenon could bring us closer what dark
00:04:20
matter really is. Now back to you, Tim The Astronomy Daily
00:04:26
Podcast.
00:04:28
Now I saw a headline, the other day and it was why Star Wars
00:04:35
needs its own answer to Star Trek. Lower deck. Star Trek's
00:04:40
animated sitcom has brought comedy to the final frontier.
00:04:44
Surely it's time that the Galaxy far, far away followed suit.
00:04:50
Strange new worlds and lower decks are both unmistakably Star
00:04:55
Trek, even though they hail from very different corners of the
00:04:58
final frontier.
00:05:00
The former plots, a similar course to Jean Roddenberry's
00:05:03
original series, a live action TV show set on the flagship of
00:05:08
the Federation crewed with familiar characters and steeped
00:05:12
in cannon lower deck. Meanwhile goes where no Trek has gone
00:05:16
before. Yes.
00:05:18
The animated series has taken Kirk Spock and the rest of the
00:05:22
original crew into the second dimension back in the 19
00:05:26
seventies. But the veteran Fran franchise has never previously
00:05:31
set its phases so bluntly too fun. The comedy show setting is
00:05:37
also far from traditional seeing as the US S Rios is in the
00:05:42
second division of star ships crewed by officers, unlikely to
00:05:47
trouble even the footnotes of Federation history.
00:05:50
Yet, when the two shows collided in those old scientists, the
00:05:55
latest episode of strange new worlds, they were able to
00:05:59
coexist organically more comic than your average SNW story and
00:06:05
more serious than the standard LD Outing the crossover ensured
00:06:10
that en signs and mana never seemed out of place alongside
00:06:16
Spock Pike and not beyond the usual fish out of water time
00:06:22
travel gags.
00:06:23
Anyway, that's largely because load has never lost sight of the
00:06:30
fact that it's first and foremost, a Star Trek show. It
00:06:33
is an animated workplace sitcom that just happens to be set in
00:06:37
the 24th century that Jean Luc Picard calls home.
00:06:41
This is a show that laughs with the franchise's long established
00:06:45
tropes rather than at them. And with the show's fourth season
00:06:49
heading for Earth later this year on September the 7th 2023
00:06:54
it's a formula that is a pro that has a proven track record.
00:06:58
It leaves you wondering why Star Wars is yet to make a genuine
00:07:02
comedy of its own or exception of James Bond.
00:07:05
That's been such a gift for comedy writers as Star Wars
00:07:10
beyond the all out goose spaceballs, family guy, et
00:07:15
cetera, et cetera. George Lucas 's Galaxy far far away has
00:07:19
provided rich pickings for everything from the big bang
00:07:22
theory and friends to robot chicken.
00:07:25
A large chunk of Kevin Smith's filmography and bad lip breeding
00:07:30
videos about the relative merits of sticks and bacon. But beyond
00:07:34
the numerous Lego Star Wars themed spinoffs and a Man's
00:07:39
Wonderful Visions episode. I am your Mother Lucas film have
00:07:43
traditionally been reluctant to play Star Wars for fun as
00:07:48
they're happier to let other people write the gags and make
00:07:52
the funny for themselves.
00:07:54
So I ask myself, isn't it time? We had Star Wars funnies. Let me
00:08:03
know what you think in a cosmos rich with planets beyond our
00:08:08
solar system, a majority tread astonishingly close to their
00:08:12
stars. But NASA's exoplanet Hunting Satellite has no spotted
00:08:18
a world with one of the longest known periods, meaning it strays
00:08:22
farther from its star adding to a, just a handful of such long
00:08:26
distance planets.
00:08:28
The newly found gas giant called to I 4660 C is about the size of
00:08:34
Saturn resides in a star system about 815 light years from Earth
00:08:40
and orbits its star every 482.82 days or 16 months. Among the
00:08:47
2000 or so worlds detected by NASA's Tess transiting
00:08:52
exoplanets survey satellite to I 46 XC is special for two
00:08:57
reasons.
00:08:58
Not only does does it have the longest year but at a frigid
00:09:02
minus 100 and 10 °F, that's minus 78 °C. The newly found
00:09:09
world is also one of the coldest among those spotted by tests.
00:09:13
Astronomers are particularly excited about this discovery
00:09:17
because based on what we know about the exoplanets we've found
00:09:20
so far, nothing really looks like our.
00:09:23
So solar system is Mail Moris, a graduate student from the
00:09:28
University Of New Mexico and lead author of the new study
00:09:32
said in a statement. So we want to find out how these different
00:09:36
types of systems formed and migrated. Now? Hay, have you got
00:09:40
a terrible joke for us this week.
00:09:42
As we talking sci-fi this week here are a couple for you. Why
00:09:46
did the board go to therapy because they had too many
00:09:50
assimilation issues. Why did Anakin Skywalker cross the road
00:09:55
to get to the dark side?
00:09:59
That's truly terrible. Hay. But thank you very much. Indeed.
00:10:03
