SPACE TRAVEL AND OUR UNIVERSE

Voyager 1 spacecraft which blasted off from Cape Carnaveral on 5th September 1977 has made history last week after traveling non stop for 43 years, at a speed of 60,000 kilometers per hour, has reached a distance of 150 Astronomical kilometers. One Astronomical kilometer is the equivalent of the distance from earth to sun (150 million kilometres) thus Voyager 1 is about 22.5 billion kilometers away from the earth as I write this (the entire distance around the earth is mere 40,000 kilometres ). The spacecraft will take another three hundred years at its current speed to reach the Oort Cloud. The Oort cloud is the boundary of our solar system, the gate into our domain. Our solar system, housing the eight planets, is located near the edge of our milky way galaxy and it's distance from the center of the galaxy is 27,000 light years. Voyager 1 need to travel 63,239 Astronomical mile to reach one light year. To calculate how far that would be is to multiply 150 million kilometers by 63,239 which is 9.4 trillion kilometers. Thus it will take voyager 1 at its current speed to travel for 16,863 years to travel one light year. The closest star to our solar system is Proxima Centauri, which is only 4 light years away. If Voyager 1 were to head towards it, it will have to be patient for 67,455 years to reach it.
Our milky way galaxy has stars, like our sun and Proxima Centauri, to the tune of 400 billion and the diameter of this galaxy is 100,000 light years apart. Therefore for Voyager 1 to traverse our galaxy from one end to another it will take 6.3 Billion years, which is more than the age of earth itself. That is just one galaxy among the over 2 trillion galaxies in our OBSERVABLE universe. If Voyager 1 could survive the voyage across our galaxy of 6.3 billion years, the next closest galaxy to our milky way is the Andromeda galaxy...do you know how far it is from our own? Just 2 million light years away....do you still think we are significant in the cosmic scheme of things?
At our current technology, traveling to the galaxy closest to us, the Andromeda galaxy which is 2 million light years away, could take us 126 billion years to accomplish, that is over 9 times the age of the universe itself. Even the light leaving that galaxy this very minute, despite light being the fastest thing we know in the universe at the speed of 186,000 miles per second, it will only arrive here in earth in the next 2 million years. All we are talking here is about the observable universe which is a mere 4.9% of the entire universe. Dark matter, the non luminous matter that couldn't be detected on the electromagnetic spectrum, together with Dark energy, made the bulk of our universe 95.1%.
That is why God asked us
Q79:27 "Are you a more difficult creation or is the heaven?"
You tell me.

Humans are insignificant on the grand scheme of things
