If Space time concept of Einstein is to be considered true, then we cant deny on below implications:

in the holographic view, if an alien moving towards earth with close to speed of light then his now would be our future.

1. now for this to happen, our future needs to deterministic (whether it has happened for us or not, that is a separate concept)

2. we all know, nature always select alternative which is low in energy. so if Big Bang to be true (for the time being), then we are constantly operating in circles, we start with big bang and eventually will end in Big Bang

3. if that is true then entropy is also cyclic, in one cycle, it can be said that it is continuously increasing but after reset of big bang, it will reduce to zero

4. but this theory have 1 issues:

a) Big Bang paradoxes

till now, we were considering Big Bang holographic cycle, since it is no longer hold true, it will raise several other questions.

lets look at the same cycle with a different view, rather than looking at the complete hologram, lets focus only one slice of it.

with the discovery of the great attractor, we all know that our milky way and galaxy are getting angular push towards it. if space time concept to be taken true then The great attractor will also create a warp in space time fabric which will make our galaxy to revolve around it. why not we say we are endelessly, orbiting around The great attractor and there was no origin (like in big bang) and it also supports other theories as well:

the other support is given below:

Asser 1. By theory of relativity, if earth is orbiting sun for the last million years without any change in orbit then it would mean, the overall movement of universe is supporting the earth's orbit. with the discovery of the Great attractor, it is clearly found that the Great attractor (with multibillion to size of earth or whole observable universe) is imposing angular motion. It simply means that our universe/galaxy/milky way is orbiting around the great attractor.Since, there is a gravitational force at play here (between The great attractor and other celestial objects), referring source 2, they must be exerting centripetal force. Even scientist themselves are claiming that it is exerting angular deviation.Source1: https://en.wikipedia.org/wiki/Great_Attractor" The variations in their redshifts are known as peculiar velocities, and cover a range from about +700 km/s to −700 km/s, depending on the ANGULAR deviation from the direction to the Great Attractor. ""The Great Attractor is an apparent gravitational anomaly in intergalactic space at the CENTER of the local Laniakea Supercluster"Source 2: https://en.wikipedia.org/wiki/Centripetal_force"In Newtonian mechanics, gravity provides the CENTRIPETAL force responsible for astronomical orbits. "

Asser 2. As per the study done by university of California, there is a growing evidence that the whole universe is following a common pattern or structure. Golden Ratio (1.61) and magic figure (1/137) all suggests that universe does follow a particular design. If we start looking at the structure of universe, it follows a certain pattern, electron is cyclic, natural cycles are cyclic, earth's orbit is cyclic, sun is orbiting black hole, milky way is round, galaxy are circular. if all the subset of a larger set are cyclic/circular, then we have to believe that parent force (angular force exerted by The great attractor on celestial bodies) and motion of our universe is also cyclic. In layman language, just like in hurricane, all of its particles will have circular trajectory because the overall shape of hurricane is cyclic/circular (but the eye remains at calm). we can consider the whole universe as big hurricane whereas its eye is at calm (I.e. The great attractor).Moreover, just like atoms have orbiting electrons around nucleus (with bulk of the mass concentrated at nucleus, similarly, the great attractor is having bulk of the mass and rest galaxies/celestial are having only approx. 15% of the mass.

Asser 3. Recent studies (in 1998) shown that the universe has an acceleration. no theory could justify this. as per this theory, since universe is also orbiting around a prime foci or the great attractor, it is now entering or exiting in perihelion zone, as all know when earth enters into perihelion, there is a change in rotational speed. that might be the prime reason why natural calamities are increasing because it is changing the gravity of the earth and hence changing the KE and potential energy of the nature. while coming it to equilibrium state, nature creating earthquake, tsunami. No theory in the existing modern age can answer all such questions, why natural calamities have increased and why universe is accelerating, change in earth’s gravity etc.Source 3: https://www.forbes.com/sites/trevornace/2017/11/20/earths-rotation-is-mysteriously-slowing-down-experts-predict-uptick-in-2018-earthquakes/#470b50226f24

Asser 4. In the 1920s, Milankovitch hypothesized that variations in eccentricity, axial tilt, and precession of the Earth's orbit resulted in cyclical variation in the solar radiation reaching the Earth. Milankovitch and other hypothesized that variation in eccentricity, axial tilt, and precession of earth's orbit are cyclical and thousands years of periodicity.this theory can only be valid if we are to believe that time is cyclic otherwise this theory loses its ground.Source 4: https://en.wikipedia.org/wiki/Milankovitch_cycles

Asser 5. According to law, total mass/energy of universe is constant. That means there are only 2 things that exists in the universe, Matter (which has a mass) and Energy. As we know that matter is also form of energy and law of conservation of energy, energy can not be created or destroyed. That brings us to the fact that Universe has finite energy.For any finite object, we can afford to take universes as closed environment. As we know in an closed environment, all motions become periodic. in layman language, if you download lunar ball or billiard game, reduce the friction to zero and cover all the pots. then no matter what shot we play, it is always going to periodic or all events will have its periodicity.

Asser 6. As recent study shows that earth magnetic fields have also changed around 200 BC and it always flips their North and South Poles. which also means they are also cyclic.Source 6: https://www.nytimes.com/2017/02/14/science/magnetic-field-earth-jars.htmlThis means the time is cyclic with Universe orbiting around The Great attractor not with Big Bang. Spacetime concept of Einstein was right, with a only tweak that like Time, we are only moving forward (yet cyclic), so as with space. New Answer to ParadoxesEven in case of Big bang, we never talked about origin of cosmos, (we always believed that hydrogen gas already there and other assumptions, whereas origin means irreversible process), in this theory, we got to believe that this peculiar skeleton of the universe cant be created, and it was always there. This structure is independent of time.
