Are humans aliens? Scientists discover why we haven’t contacted ETs yet

As per estimates of scientists, around one billion earth-size planets are present in the Milky Way galaxy. A recent theoretical study suggests that because the Earth was born early into the evolving universe, most habitable planets may not have been born yet. The rest will, over the remaining trillions of years of the universe’s lifetime, coalesce into stars whose solar systems will contain a myriad of Earth-like planets (artist’s representations above).

Scientist Researchers Peter Behroozi and Molly Peeples, both of the Space Telescope Science Institute (STScI) in Baltimore, Maryland, have suggested Earth-like planets are let to develop.

Scientists think that there are around 1 billion of Earth-sized habitable planets in our Milky Way alone right now and there are many others to be born all over the universe. “The bulk of those planets – 92 percent – have yet to be born”, NASA explained.

Behroozi is the lead author of the new study, which was published this week in the journal Monthly Notices of the Royal Astronomical Society.

“And, the party won’t be over when the sun burns out in another six billion years”.

The study displays that the universe was creating stars at a break-neck speed 10 billion years ago, but the portion of the universe’s hydrogen and helium gas that was associated was very low.

As early residents of the universe, we are lucky to have developed powerful telescopes like Hubble to document our lineage from the Big Bang through the primordial galaxy. That is, habitable planets must be distributed through the universe at such and such density, based on our observations of that universe at this moment in time, therefore contact is not improbable.

Yes, reports from NASA confirm that the Earth is in fact the earliest planets to form in the solar system. As the Space Telescope Science Institute puts it: “That’s plenty of time for literally anything to happen on the planet landscape”. Today, star birth is happening but at a very slower rate, still there is so much raw material left that universe will keep making stars and planets for many more years to come.

Kepler data revealed that potentially habitable planets located within their stars’ habitable zones are quite many in our galaxy.

For any future civilizations down the road, possibly in a trillion years’ time, the universe will look like a vastly different place.

The time frame in which our planet was created paired with our scientific capabilities means we are ideally placed to observe evidence of the cataclysmic creation of the cosmos and its evolutionary path, by studying ancient light and electromagnetic radiation.
