To this excellent post of eminent scholar Sri Raj Vedam, i would like to share my 2 cents of speculative reconciliation on the feasibility of time travel accounts provided in the Holy Hindu scriptures.

IMHO I think it all boils down on what one means by concepts like "Time" and "Travel”. These concepts have been some of the most debated and speculated topics not only in ancient philosophical traditions across the globe but also medieval philosophies as well as modern sciences. Particularly, the ontological and epistemological status of time is one of the most important questions debated across different schools of philosophies. Take the Indian scenario itself, there are considerable differences in between each of these pairs of schools viz. नयाय & वैशेषिक दर्शन (nyāya & vaiśeṣika darśana), योग & सांख्य दर्शन (yoga & sāṁkhya daṛśana), उत्तर /वेदान्त & पूर्व मीमांस दर्शन (uttara / vedānta & pūrva mīmāṁsa darśana). The Buddhists and Jains have their own customized versions as well. Similarly, in the western world there are a variety of schools.

While some schools consider काल (kāla - time) as an
independent ontological entity – दरव्य (dravya - element), while for others it is just an epistemological
construct.; similarly, for some it is a धर्मि (dharmi –
substantial), while for others it is धर्म (dharma -attributive); again, some schools believe that time momentary, while
others say it is enduring, while still other believe it is perduring. For some time is linear (flat space-time), for some it
is cyclical, while for still others it is spiral. Classical physics considers
time is static and absolute, whereas relativistic physics considers it dynamic
and relative. Certain schools of quantum physics consider time not as a
fundamental principle, but as a derived or emergent one. In a nutshell,
there is no single universally accepted model of time either in religion,
philosophy or for that matter even in physics.
The next
important concept to understand is that not only there are striking differences
in the ontological viewpoints on time across philosophical schools, but there
are also differences in the measurement scales of time i.e. defining the units
and durations of time scales. Before proceeding further, please remember that
both according to ancient Hindu philosophical wisdom, as well as modern
relativistic-quantum physics देश (deśa -
space) & काल (kāla - time) are not considered as two isolated entities but
as one integrated संप्रवाह (saṁpravāha - continuum) called the
fabric of देश-काल संप्रवाह (deśa-kāla saṁpravāha – space time
contiuum).
For
example, according to the श्रीमद् भागवत महापुराण (śrīmad
bhāgavata mahāpurāṇa) the denomination of space-time begins from microscopic subatomic
scales of परमानु (paramānu), अनु (anu), त्रसरेनु (trasarenu),
त्रुति (truti), वेध (vedha), लव (lava); through मानुष्य काल (mānuṣya
kāla – human time) of meso-time
scales निमिष (nimiṣa), क्षण (kṣaṇa), काष्ठा (kāṣṭhā), लघु (laghu), नाडिक (nāḍika), मुहूर्त (muhūrta) दिन (dina -
day), सप्ताह (saptāha -week), पक्ष (pakṣa -
fortnight), मास (māsa - month), आयन (āyana – half year), वर्ष (varṣa -
year), युग (yuga - aeon), महायुग (mahā yuga
– grand epoch), मन्वन्तर (manvantara – patriarch era), कल्प (kalpa) etc. In a
nutshell, the comprehensive timescale roughly spanning from nano-seconds to
more than trillions of years. Many scholars, scientists and subject matter
experts are testifying that these time scales are astonishingly very close to
modern cosmological estimates.
In many
scriptures the length of the महायुग (mahā yuga) is
considered to be 43,20,000 solar (human) years. Which is further split
into चतुर् युग काल (catur yuga kāla – fourfold epoch
period) in the ratio of 4:3:2:1 across 17,28,000 years of कृत्या युग (kṛtyā yuga
– creation epoch), 12,96,000 years of त्रेतायुग (tretāyuga
– third epoch), 8,64,000 years of द्वापर युग (dvāpara
yuga – second epoch) & 4,32,000 years of कलियुग (kaliyuga –
dark/black epoch) respectively. 71 such महायुग (mahā yuga
– grand epochs) constitute what is called as a मन्वन्तर (manvantara
– manu’s period) and 14 such मन्वन्तर (manvantara
– patriarch periods) constitute a कल्प (kalpa -aeon) which
in turn corresponds to 24 hours (=12*2) or 1 ब्रह्मअहोरात्रि (brahma
ahorātri – daytime of brahma) and 720 (=360 *2) such ब्रह्मअहोरात्रि (brahma
ahorātri – daytimes of brahma) corresponds to 1 ब्रह्म वर्ष (brahma varṣa
– brahma year). 100 such years correspond to ब्रह्म आयुश् काल (brahma
āyuś kāla – brahma’s lifetime). And more importantly, such scales
are cyclical wherein the events are repetitively recurring.
In fact, the दश महा विभव अवतार (daśa mahā vibhava avatāra - ten supreme glorious incarnations) of Lord श्री महा विष्णु (śrī mahā viṣṇu) is also uniformly spread across चतुर् युगकाल (catur yugakāla - four-fold epoc period) i.e. one महा विभव अवतार (mahā vibhava avatāra - supreme glorious incarnations) for every 4,32,000 years. In other words, the golden ratio 4:3:2;1 is applicable not only to the epochs (yugas) but also to the incarnations (avataras).
In this context, just as there are temporal units of measure discussed above, there are spatial measures as well. For example, the temporal ranges discussed so far belongs to the realm of human consciousness operating within the spatial range of मनुष्य / भूलोक काल (manuṣya bhūloka kāla / bhūloka – human /terrestrial spacetime fabric /plane). But this is not the only space-time realm. There are still higher realms of spiritual consciousness viz. देव लोक काल (deva loka kāla – heavenly space-time plane) which has time scale ranges like देव अहोरात्रि (deva ahorātri), देव वर्ष (deva varṣa), देव युग (deva yuga) etc. However, even this is not the end of Hindu time scales. There are still higher degrees of spiritual space-time realms like the ब्रह्म लोक काल (brahma loka kāla) having time scale ranges like ब्रह्म अहोरात्रि (brahma ahorātri), ब्रह्म वर्ष (brahma varṣa), ब्रह्म युग (brahma yuga) etc. and even further extends to विष्णु लोक काल (viṣṇu loka kāla) and शिव लोक काल (śiva loka kāla) each possessing corresponding time-scale ranges like विष्णु अहोरात्रि (viṣṇu ahorātri), विष्णु वर्ष (viṣṇu varṣa), विष्णु युग (viṣṇu yuga) & शिव अहोरात्रि (śiva ahorātri), शिव वर्ष (śiva varṣa), शिव युग (śiva yuga) etc., respectively.
In fact, the दश महा विभव अवतार (daśa mahā vibhava avatāra - ten supreme glorious incarnations) of Lord श्री महा विष्णु (śrī mahā viṣṇu) is also uniformly spread across चतुर् युगकाल (catur yugakāla - four-fold epoc period) i.e. one महा विभव अवतार (mahā vibhava avatāra - supreme glorious incarnations) for every 4,32,000 years.

Thus, each
realm has a relative frame of reference and of course there is a mathematical
mapping relating these realms. Like a मानुष्य वर्ष (mānuṣya
varṣa – human year) in the भूलोक (bhūloka – terrestrial plane) corresponds to a देव अहोरात्रि (deva
ahorātri – divine daynight) in देव लोक (deva loka
– heavenly plane). Similarly, there are corresponding mappings between देव लोक काल (deva loka
kāla – heavenly space-time plane), विष्णु लोक काल (viṣṇu loka
kāla) & शिव लोक काल (śiva loka kāla).
Based
on the account given in the sacred श्रीमद् भागवत महापुराण (śrīmad
bhāgavata mahāpurāṇa), at present (as on 14th June 2018),
in the capacity of ordinary mortals are operating currently from भूलोक (bhūloka –
terrestrial plane) in the 5118th year in the 4th phase of the चतुर् युग काल (catur yuga
kāla – fourfold epoch period) viz. कलियुग (kaliyuga –
dark/black epoch) of the 28th महायुग (mahā yuga
– grand epoch) in the वैवस्वत मन्वन्त्र (vaivasvata
manvantra) which is the 7th मन्वन्तर (manvantara
– patriarch era) within the श्वेतवराह कल्प (śvetavarāha
kalpa) in the 51st ब्रह्म वर्ष (brahma varṣa
– brahma year). The eminent Indian astronomer श्री वराहमिहिर (śrī
varāhamihira) in his phenomenal work सूर्य सिद्धान्त (sūrya
siddhānta) very clearly testifies this model.
However,
the next important point to understand is that while referring about the time
scales in the Indian scriptural context viz. इतिहास (itihāsa - epic), पुराण (purāña - mythology), ज्योतिष
शास्त् (jyotiṣa śāstra – astrological
literature), there seems to be some discrepancies regarding the durations
amongst different scriptures. For example, some eminent astronomers do not
subscribe to the above ratio (4:3;2:1). श्री आर्यभट्ट (śrī
āryabhaṭṭa) in his monumental work आर्यभाटीय (āryabhāṭīya) states that
the महायुग काल (mahā yuga kāla – grand epoch
period) is distributed in equal proportions across the चतुर् युग (catur
yuga– fourfold epochs) viz. 10,80,000 years each.
Similarly,
लगध महऋषि (lagadha mahaṛṣi) in his magnum opus masterpiece वेदाङ ज्योतिष (vedāṅga
jyotiṣa) which is considered to be one of the oldest astrological
(astronomical) treatise does not talk about such huge time scales. In fact,
instead of the चतुर् युग काल (catur yuga kāla – fourfold epoch
periods) spanning to lakhs of solar years, he only refers to a period of
five-fold solar years viz. सांवत्सर (sāṁvatsara),
परिवत्सर (parivatsara), इदावत्सर
(idāvatsara), अनुवत्सर (anuvatsara) & उद्रवत्सर
(udravatsara) respectively (totaling to approximately 12830 human days) which
is again a reflection of the definitions in the ancient वेद शास्त्र
(veda śāstra) like the तैत्तिरीय ब्राह्मन (taittrīya
brahmana).
Please
do not get confused between such vast differences between these two strikingly
different models of युग (yuga - epoch) system. Although both the models commonly leverage
the term युग (yuga - epoch) to represent time scales, yet they target completely
different functionalities. The former is used to measure cosmological
phenomena, while the latter serves more for social and ritualistic calendar
purposes. In other words, they are similar but not the same. Once we understand
this, the seeming disparities (inconsistencies) in yuga definitions will
reduce.
With this
general background overview on time scale models, let us get back to the topic
of time-travel. The Indian scriptural corpus is pregnant with multiple accounts
of such time-travel episodes. There are ample case studies in the महाभारत (mahābhārata), महापुराण शास्त्र (mahāpurāṇa śāstra – mythological
literature), (yoga vaśiṣṭa) beautifully demonstrating
time-travel. For example, श्री नारद महामुनि
(śri nārada mahāmuni) for
example is one of the most popular space-time traveler mentioned across almost
all the पुराण शास्त्र (purāṇa śāstra – mythological
literature). The story of ककुद्मी (kakudmī), लीला (līlā) are other very popular
examples. But one may be wondering how is such time pravel
physically possible particularly when traveling across prohibitively large
astronomical distances, considering the physical limitations posed by the laws
of relativistic physics.
The
conventional view is a common-sense logic according to
linear sequencing of time scales, also referred as ‘mesotime scales’.
Such a linear flow of time is also called ‘psychological time’ in modern
physics. It’s a great model for all practical purposes and
I personally am fine with it.
But this is
not the only model discussed in ancient religious philosophies as well as in
modern science. The temporal models referred in the पुराण शास्त्र (purāṇa
śāstra – mythological literature) are spirally cyclical models spanning
great ranges of time scales.
Now,
coming the main crux of your genuinely valid observation/concern raised in the
comment. Instead of look at these massive time scales in a unidirectional
linear mode which makes it difficult for the feasibility of time travel.
However, this difficulty can be theoretically reduced if we begin to consider
other alternate space-time geometric models. For example, instead of the linear
model we can consider a spirally cyclical model. Such spiral model is also
speculated by many physicists including Frank Tipler the eminent mathematician
physcist. Again, typically, such spiralized space-time geometry, one can
conceive two different paths or trajectories viz.
·
क्रमक यात्र (kramaka yātra – gradual travel / pilgrimage): one is traversing along the spiral curve which
is the longer path. One can visualize such a spiral channel as a perdurant
tube, and any cross-section (arc) in the 3+1D curve is considered as a
space-time (block universe) containing both spatial parts and temporal
parts.
·
सुवेग यात्र (suvega yātra – rapid travel / pilgrimage): In this case instead of the regular trajectory
of gradual progress, a spiritual adept takes a short cut viz. a direct vertical
line (and that is the perpendicular distance which mathematically is the
shortest distance between the source and target points) by making a hole
(technically called a worm-hole) through the space-time warp (tunnel).
According
to many scriptures महायुग (mahā yuga) cycles
can also be shrunk accordingly, as done in the scriptures itself. The कलियुग (kaliyuga –
dark/black epoch), द्वापर युग
(dvāpara yuga
– second epoch), त्रेतायुग (tretāyuga) & कृत्या युग (kṛtyā yuga) is
stated to be 4,32,000 years in some scriptures at the same time, another
scripture scales same as just 4,320 years and still others provide a similar
but slightly different time-scales. This seeming disparity between them
will be cleared if we understand the laws of relativity viz. relative frames of
references used across different scriptural versions which need to be
interpreted from perspectives viz. Vertical vs spiral etc.
For example, the duration in terms of vertical scales of of 43,20,000 मनुष्य / भूलोक काल (manuṣya bhūloka kāla / bhūloka – human /terrestrial spacetime fabric /plane) distributed across चतुर् युगकाल (catur yugakāla - four-fold epoch period) in the golden ratio (4:3:2:1) as 17,28,000:12,96,000:8,64000:4,32,000 can be temporally dilated (mapped / reduced) to 12,000 ब्रह्म लोक काल (brahma loka kāla - divine spacetime) distributed in the same ratio as 4,800: 3,600: 2,400: 1,200.
Please remember that as established by Einstein's General relativity ...Time is not an absolute measure but a relative measure based on the frame of reference. The life time of भगवान् श्री रामचन्द्र मूर्ति (bhagavān śrī rāmacandra mūrti) can be considered from both scales...based on your personal belief system or frame of reference.

Moreover,
we should understand that time, as testified in many schools of ancient
metaphysics as well as modern medieval ontological philosophy and even modern
physics, time is not absolute of linear unidirectional tensed flow from past,
through present, to the future. It rather is a tense-less enduring continuum
(field). Time is a special kind of spatial extension and hence all the three
tenses of time along with the spatial dimension persist always. However, as
part of our constrained empirical consciousness only three spatial dimensions
and one temporal dimension (which is the present tense) is perceivable at any
instance. In other words, past and future entities are as real and enduring as
the one in the present tense. Just as distant places far away are as real and
enduring.
However,
ordinary mortals like us whose locus of conscious awareness is typically
confined (bundled) to the triple realms of अन्नमय कोश
(annamaya kośa – food/body sheath), प्राणमय कोश (prāṅamaya kośa – mind sheath) and the मनोमय
कोश (manomaya kośa) and operating within the triple states of जग्रत् अवस्त् (jagrat avasta-wakeful state), स्वप्न अवस्त् (svapna
avasta – dream state) & सुशुप्ति अवस्त् (suśupti
avasta – sleep state) respectively, can only empirically experience the present
instance as a tangible consciousness of an extra-mental spatiotemporal objective
reality. This is because, we still bound by the त्रिमल
(trimala – triple fetters) viz. आणव/
अणुत्व ( āṅava /
añutva – minuteness/atomicity), कर्म
(karma - fate) & माया (māyā - delusion) respectively because
of which the mind differentiates between the अस्मद् (asmad – I/me) and न
अस्मद् (na asmad – not
I/me) – in other words the विषयिन् विषय भेद (viṣayin viṣaya bheda –
subject-object discrimination). One of the best ways to understand
this concept is through the Minkowiski’s famous space-time diagram wherein
the present tense (the now-here moment) is an intersection of the past and the
future light-cones. the three dimensions of space hypersurface intersects the
present-tense of time All spatio-temporal parts falling within the light-like
cone boundary within perceptional boundaries while others are not.
On
the other hand, for spiritually evolved souls, whose higher faculties of ब्रह्म ज्ञान सिद्धि (brahma ṇana siddhi – spiritual /
para normal potencies) are awakened are no longer bound by the अहंभाव
(ahaṁbhāva aṇutva – self
arrogating minuteness) in terms of विषयिन् विषय भेद
(viṣayin
viṣaya
bheda – subject-object discrimination). In other words, space-time
continuum is fully pervaded by their mind and hence their journey space-time is
no longer an extra-mental journey but an inner journey which again is a yogic
time-travel. through the yogic technique of प्राण अग्निहोत्र (prāṅa agnihotra),
they travel in mind and as we know mind is the fastest traveler. of course,
much faster than light as well. For example, although Sun light takes 8 seconds to reach us, and even millions of light years for light to reach us from a distant star or galaxy, we can instantaneously think of the Sun or distant star through my mind. Hats of to mind -the greatest gift of God to man!
So the faster than light limitation is no longer applicable to such adepts. The yogically activated आधार चक्र (ādhāra cakra – base canters) in their सूक्ष्म ज्ञानदेह (sūṢma jñāna deha – subtle gnostic body) acts as the worm-hole through which the time-travel is made feasible.

Again, please remember that it is not necessary that these yogic
adepts physically travel through spatial world-line to reach the target
destination. Unlike for ordinary mortals, for them the whole multiverse is a
omnj-jective continuum wherein the yogi is an endurant force capable of
entangling even with any non-local entity.
They teleport through what
is technically called in Minkowisky’s model as the ‘time-like’ worldline where
the impact of gravitational resistance of spatial mass is minimized and the
actual teleportation is only de-materialized (spiritualized) as quantum
information wave viz. – मन्त्र नाद स्पन्दन (mantra nāda spandana - theosonic
vibrations) which is then rematerialized (cloned) as the entangled polarity at
the target. In other words, their स्थूल भूत देह (sthūla
bhūta deha – gross physical body) made up of the पञ्च महा
भूत (pañca mahā bhūta – five physical
elements) is spiritualized, through a technique which can be called as विप्रतीप पञ्चिकर्ण
(vipratīpa pañcikaraṅa – reverse
quintuplication), into ज्ञान देह (jñāna deha- gnostic /
information body). Please remember that in accordance with the laws of
quantum thermodynamics, the aroused प्राणाग्नि (prāṅagni
– vital heat) serves
as the medium (channel) for वाक् शक्ति (vāk śakti
information-energy) helping in breaking the information-entropy which otherwise
constraints the arrow of time.
