What would happen if we sent a scientist back in time 30,000 years?

All things considered, the first issue I see is that the world was distant from our present spot 30.000 years prior, because the Sun circles the Galaxy at 230 km/s.

This implies the Sun moves round the focus of the Galaxy 217 trillion km in 30.000 years, which resembles 23 light-years.

Regardless of whether you moved back in time just one second you’d end either out of the environment or entombed under 230 km beneath the surface of the world .

We will, in general, imagine that the Sun is static:

this is the manner by which it moves around the Galaxy and how the planets make winding circles around the Sun. 

By chance, the circle of the Sun around the focal point of the Galaxy is eminently roundabout,

which implies that the Sun never draws near to the Black Hole in Sagittarius B.

That, to a limited extent, clarifies why the Earth is livable, on the grounds that the focal point of the Galaxy is very forceful to life, yet I diverge. 

In addition, the circle of the Sun “wobbles” here and there in the Galactic plane this way: 

The Sun moves “upward” from the Galactic Equator 250 light-years and withdraws another 250 light a very long time in 66 million years 

In 30.000 years the Sun and Earth would dislodge around 0.1 light-years away or towards the Galactic Equator. 

We don’t see very well how this development carries on. 

In any case, pause! There is more! 

Presently, the Galaxy is likewise moving towards the group of stars of Leo at 590 km/s… just about .

All the developments I even have discussed are predominated by the speed where we move towards the Virgo supercluster.

We have an ambiguous thought of how we are moving, we just realize that we move just about towards the Leo group of stars, and our development is suffering from numerous worlds in our neighbourhood:

Right now Milky way is set apart with the yellow letters “MW” and this is the best estimate we have of the present development of the various worlds 

In this way, generally, 30.000 years back, the whole Galaxy would be dislodged 59 light-years from Leo and lemme let you know,

we don’t know very well in which heading due to the impact of numerous Galaxies near our own, similar to Magellan Clouds. 

Along these lines, you need not exclusively to head out in time yet to go in space a limit of 23+59 = 82 light-years. 

In this way, it isn’t sufficient to have the innovation to go back in time 30.000 years. 

You likewise a requirement for the researcher to be moved back in time alongside a spaceship that has the innovation to move around,

suppose, 80 light-years, to where the Sun and Earth were in that age before this researcher can arrive on Earth. 

The Terminator radiant innovation wasn’t time travel, on the off chance that you simply follow my float:

the person moved exposed through space during a non-distinguished spaceship to point out up to Earth.

In any case, Arnold had it simple, contrasted and what you propose: he moved a few of years in time while you’re discussing 30.000 years.

This implies the spaceship you send back in time would not be sufficient. 

This researcher does not just need to go for 80 light-years:

he needs to live over 80 years in the wake of showing up to the past to have the option to arrive at where Earth was 30.000 years back. 

All things considered, he should make a trip to the “Earth-in-past-time” at speeds probably littler than that of light speed. 

At last, he would have a moderately confounded issue simply discovering Earth the same number of stars around the Earth would be uprooted by in excess of a minor sum and the vulnerabilities about Galactic and Solar development are huge. 

The colossal issue, I think.
