Though it may come as a big surprise to you, the fact is — all of us are travelling in space at a speed as high as 1027.7 times the speed of sound.

And definitely — I am not talking out of hat.

Here are all facts and figures that prove that all of us are travelling in space at a speed as high as 1027.7 times the speed of sound.

The facts and figures

Is it not true that we also revolve around the Sun at the same speed at which the Earth revolves around the Sun?

Well, as we know — the Earth revolves around the Sun at an average speed of about 1,674 km/hr.

So we also revolve around the Sun at an average speed of about 1,674 km/hr.

Any doubt about it?

Next …

Though we are travelling at this speed around the Sun, the fact is — the Sun is revolving around the black hole of the Milky Way also along with its all planets (including the Earth) at an average speed of about 828,000 km/hr.

So we are also travelling around the black hole of the Milky Way at the same speed.

However because the direction in which the Earth is moving around the Sun and the direction in which the Sun is moving around the black hole are not same, we are not travelling at a speed of 1,674 + 828,000 km/hr — the arithmetic sum of their speeds.

We have to treat the speed 1,674 km/hr as well as the speed 828,000 km/hr as vectors.

If we may treat the speed 1,674 km/hr as the vector “V1” and the speed 828,000 km/hr as the vector “V2 ”, we may say — we are travelling in space at a speed of “V1+ V2”, as shown in the following diagram.

Though we should calculate the value of “V1 + V2” using the formula “V1 + V2 = √(V1² + V2² +V1.V2 Cos A)” where ∠A is ∠BAC, the fact is — we can calculate the value of “V1+ V2” by this method only if we know the value of “∠A”.

Since the value of “∠A” keeps on changing, obviously — this method does not suit us.

So we need some shortcut.

Luckily, we don’t have to hunt for a shortcut.

I have found out the shortcut.

The shortcut

We may calculate the value of “ ” even by multiplying “V1 + V2” with 0.9 because even if we calculate the value of “ ” using this formula, its value is expected to lie between 0.85 to 0.95 times “V1+V2” most of the time.

So we may say, we are travelling at a speed of approximately 0.9 times “828,000 + 1,674” that is — at a speed of about “746,706.6 kilometers per hour” in space.

But the fact is, the Sun is not travelling only around the black hole.

It also oscillates as shown in the following diagram.

At present, it is climbing at a speed of approximately 25,200 kilometers per hour above the galactic plane.

Though you shall get a different value of this speed depending upon the source from where you may pick up this figure, I picked up this figure from “Poe”.

If we may denote this speed of the Sun by the vector “V3 ” and add it to “V1 + V2” by multiplying “746,706.6 + 25,200” by “0.9”, we shall get the approximate value of “V1 + V2 + V3” which works out to a figure of “694715.94 kilometers per hour”.

But besides climbing above the galactic plane, Sun is also travelling toward the constellation Hydra along with its all planets at an approximate speed of 72,000 kilometers per hour.

Let us designate this speed as the vector “V4 ”, add it to “V1+V2+V3” and multiply it by “0.9” to arrive at a value of “V1+V2+V3”+V4”.

If we multiply “694715.94+72,000” by “0.9”, it yields a figure of “690,044.346 kilometers per hour”.

So we may say, the value of “V1+V2+V3”+V4” is around 690,044.346 kilometers per hour”.

According to “Poe”, our galaxy is moving toward the Centaurus constellation at an approximate speed of 720,000 km/hr.

If we may designate this speed by the vector “V5 ”, add it to “V1+V2+V3”+V4” and multiply it by “0.9”, we may calculate the value of “V1+V2+V3”+V4+V5”.

If we multiply “690,044.346 +720,000” by “0.9”, it yields a figure of “1,269,039.9 kilometers per hour”.

SO WE MAY SAY, THE VALUE OF “V1+V2+V3”+V4+V5” IS ABOUT “1,269,039.9 KILOMETERS PER HOUR”, WHICH IMPLIES THAT WE ARE CONSTANTLY TRAVELLING IN SPACE AT AN AVERAGE SPEED OF ABOUT 1027.7 TIMES THE SPEED OF SOUND BECAUSE THE SPEED OF SOUND IS 1234.8 KM/HR — ANY DOUBT ABOUT IT?
