Worm Holes pt2

Episode Transcript

Speaker 1 (00:00):
Hello, folks, it's time once again for another episode of
the Time Travel Unravel podcast, the show dedicated to all
the fascination of traveling through time. We're doing it as
we speak. Did you know you were flying through space
right now, hurtling at twenty thousand miles per hour and

(00:22):
give or take a few don't quote me on that.
That means that you're flying through time traveling. Today's episode,
we're going to talk about some theoretical time travels hopefully
we can see in our lifetime. We're gonna take a
look at wormholes. Otherwise known as Einstein Rosen bridges. First

(00:51):
proposed by Albert Einstein and Nathan Rosen in nineteen thirty five,
the Einstein Rosen bridge is a theoretical solution to the
equations of general relativity. It describes a bridge or shortcut

(01:12):
connecting two separate points in space time. These bridges are
theoretically identical to what we now call wormholes. The Weinstein
and Rosen did not originally intend for them to be traversible.
According to general relativity, massive objects warp through fabric of

(01:37):
space time. A wormhole is a structure that could theoretically
allow a person or object to travel between two distant
points in space or time instantaneously by creating a shortened
path through space time. Talk about types of wormholes such

(02:04):
as traversible wormholes. These are hypothetical wormholes that can be
used for travel between two points in space time. They
require exotic matter material with negative energy to keep them open,
preventing them from collapsing under the forces of gravity. Non

(02:30):
traversible wormholes are wormholes that are theoretical but would not
allow for safe travel. For example, a wormhole that collapses
too quickly after being formed or that contains a singularity
at its center would not be traversible. Wormholes can also

(02:55):
be classified by their geometry. For example, a maximal wormhole
as a throat that allows for the largest possible travel space,
while a Schwarzchild wormhole has a single throat but is
not traversible due to the singularity at its center. Now

(03:18):
for wormhole creation and stability, for a wormhole to remain
open and stable, it would require exotic matter with negative
energy density. This exotic matter counteracts the attractive force of gravity,

(03:40):
preventing the wormhole from collapsing. The amount of exotic matter
required is vast and currently beyond our technological capabilities. Some
theoretical models propose the use of electromagnetic fields or quantum
fluctuations to stabilize wormholes. However, these methods are purely speculative

(04:06):
and face numerous challenges, particularly in terms of generating the
required amounts of exotic matter. While the concept of artificially
creating a wormhole remains in the realm of science fiction,
some scientists hypothesize that wormholes could naturally form in certain
regions of space time, though the conditions needed for this

(04:30):
are still not well understood. Now, let's dive into wormholes
in quantum mechanics. One of the key connections between wormholes
and quantum mechanics is the concept of quantum tunneling, where
particles can pass through barriers that would otherwise be impenetrable.

(04:55):
Wormholes might provide a macroscopic analog to this phenomenon, allowing
for instantaneous travel across vast distances. Quantum entanglement, the idea
that particles can be instantaneously connected across vast distances, has

(05:16):
led some researchers to suggest that wormholes could be a
physical manifestation of quantum entanglement, offering a potential way for
information to travel faster than light. In quantum mechanics, information
cannot be destroyed, which conflicts with the idea that wormholes

(05:40):
might allow information to escape from black holes. This paradox
as a spurred debate on whether wormholes could be used
to send information of backwards in time without violating the
laws of physics. Now, let's take a look at wormholes
and time travel. If wormholes can connect two distant points

(06:04):
in space time, it stands to reason that one could
potentially use them to travel backward or forward in time. However,
to travel backward, one would need to manipulate the geometry
of space time in a way that allows for a
closed time like curve, a concept that could theoretically allow

(06:27):
for time loops. One of the key concerns with time
travel via wormholes is the possibility of paradoxes. The grandfather
paradox is one famous example. If a person travels back
in time and prevents their grandfather from meeting their grandmother,
it would create a contradiction where the time traveler could

(06:51):
never have existed in the first place. Some physicists suggest
that quantum mechanics might allow for the resolution of paradoxes
via many world's interpretations, where multiple timelines exist concurrently, allowing
for both the prevention and continuation of events in different

(07:13):
branches of reality. Now for some practical challenges of wormholes.
The sheer amount of energy needed to create a stable
wormhole is far beyond anything humanity can currently generate. Some
estimates suggest that the energy required would exceed the mass

(07:36):
energy of an entire galaxy. Finding exotic matter or negative
energy remains one of the most significant barriers to wormhole creation. Currently,
no known materials exhibit the required properties, although certain quantum
field theories suggest it may be possible under specific conditions.

(08:01):
Even if a wormhole could be created, there would be
no guarantee of its stability. A traversible wormhole could collapse
at any moment, potentially trapping its occupants or causing other
catastrophic events. Now, let's look at wormholes in popular culture.

(08:22):
Wormholes have been a popular plot device in numerous science
fiction movies and TV series, such as Interstellar, Star Trek,
and Stargate. These depictions often focus on wormholes as portals
for instantaneous travel between distant locations or times. Authors like

(08:44):
Kip Thorne, who worked as a scientific adviser on Interstellar,
have also explored the theoretical underpinnings of wormholes in their works.
Thorne's book The Science of Interstellar provides a detailed look
at how wormholes could theoretically work in the context of
modern physics. And now, for time travel. In Einstein's theory

(09:12):
of general relativity, time is not absolute and can be
affected by the speed of an object or the gravitational
field it is in. As an object approaches the speed
of light or enters a strong gravitational field, time appears
to slow down relative to an observer outside of the field.

(09:36):
This phenomenon, known as time dilation, provides a form of
time travel to the future. We are all time traveling
right now. While time dilation allows for travel to the future,
at least in theory, traveling backward in time is much

(09:58):
more problematic. Some solutions to the equations of general relativity,
such as rotating black holes, suggest that time travel to
the past could be possible, but these solutions remain speculative. Unfortunately,
that's all the time we've got for today's episode of

(10:21):
the Time Travel and Travel, and I can't thank you
enough for listening. Until next time,
