Scientists have warned that Earth could one day be stranded and “left alone” as the universe expands rapidly.

And the American astronomer Edwin Hubble and others discovered in the 1920s that the universe is expanding, and they showed that most galaxies escape from the Milky Way, and the farther away from it, the faster it escapes. Here, Hubble defines an approximately constant ratio between speed and distance, which is known as the Hubble constant.

For every additional megaparsec (a measure of distance equal to one million parsecs or 3.26 million light-years) of distance, Hubble found that galaxies recede at 500 kilometers per second (310 miles per second) as they move away from Earth a million parsecs.

Therefore, the value of the Hubble constant is set at 500 kilometers per second per megaparsec. Over the years, astronomers have significantly revised this estimate as technologies have improved.

But Hubble laid the foundations for what scientists know today, and through the NASA telescope of the same name, the Hubble Space Telescope was able to astronomers look into the depths of the universe, and the telescope allowed scientists to move forward and note that the universe is already expanding.

But, according to Professor David Kaiser of the Massachusetts Institute of Technology, the universe is not just expanding and expanding. Speaking during the BBC series, entitled: “The Universe: Where Everything Begins and Ends” (Universe: Where everything begins and endsIt’s actually getting bigger and faster,” Kaiser said.

Most observations indicate that the expansion of the universe will continue forever. If so, the popular theory claims that the universe will cool as it expands and eventually become too cold to sustain life..

This could, in the end, leave planets like Earth alone, suspended in space, in the face of freezing days. This is what Professor Larry Gladney of Yale University suggested during the documentary series.

He said: “We can well imagine that the universe will continue to expand and become so large that galaxies will eventually disappear. They will be so far away from us and moving so fast that we have no hope of seeing any light from them. This is a real possibility of what could happen in the future.“.

And dark energy, the mysterious force that is causing the rate of expansion of our universe to accelerate, could force the space between groups of galaxies to grow at an ever-increasing rate..

With this in mind, some theories point to the possibility of a scenario called “heat death”.

This scenario was put forward as the ultimate fate of the universe, indicating that it could evolve into a state in which there is no thermal energy and therefore would not be able to sustain processes that increase entropy, a measure of the amount of energy unavailable to do something (a measure of chaos within a system ).

Scientists, through means such as the Hubble Space Telescope, have collected a great deal of information about the universe. They used these observations, along with previous calculations, to develop a model now known as the Big Bang to help explain the formation and evolution of the universe.

This model states that about 13.8 billion years ago, all matter in the universe was concentrated in one very small point. From this precise point, the entire universe expanded outward to what exists today.
