Is the only planet that we live in?
Earth is the only planet in the universe known to possess life.
What universe do we live in?
Our home galaxy, the Milky Way, contains at least 100 billion stars, and the observable universe contains at least 100 billion galaxies. If galaxies were all the same size, that would give us 10 thousand billion billion (or 10 sextillion) stars in the observable universe.
Are we the only ones in the solar system?
Our solar system is just one specific planetary system—a star with planets orbiting around it. Our planetary system is the only one officially called “solar system,” but astronomers have discovered more than 3,200 other stars with planets orbiting them in our galaxy. That's just how many we've found so far.
Does the universe just go on forever?
Many think it's likely you would just keep passing galaxies in every direction, forever. In that case, the universe would be infinite, with no end. ... Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space.
Do we live on Earth or in Earth?

What was before the universe?
The Universe has not existed forever. It was born. Around 13.82 billion years ago, matter, energy, space – and time – erupted into being in a fireball called the Big Bang. It expanded and, from the cooling debris, there congealed galaxies – islands of stars of which our Milky Way is one among about two trillion.
What exists beyond the universe?
The universe, being all there is, is infinitely big and has no edge, so there's no outside to even talk about. Oh, sure, there's an outside to our observable patch of the universe. The cosmos is only so old, and light only travels so fast. ... The current width of the observable universe is about 90 billion light-years.
How many Earth like planets are there in the universe?
One 2020 study that analysed Kepler data calculated that the Milky Way could harbour as many as six billion Earth-like planets, while another estimated the number of potentially habitable planets in our galaxy at about 300 million.
When did Pluto stop being a planet?
When Pluto was reclassified in 2006 from a planet to a dwarf planet, there was widespread outrage on behalf of the demoted planet.
How many planets are there in the Universe 2020?

How will universe end?
Astronomers once thought the universe could collapse in a Big Crunch. Now most agree it will end with a Big Freeze. ... Trillions of years in the future, long after Earth is destroyed, the universe will drift apart until galaxy and star formation ceases. Slowly, stars will fizzle out, turning night skies black.
Where does the earth end?
According to a paper that was published in the Journal of Geophysical Research-Space Physics, the border between the two—the so-called Karman line—sits 73.2 miles (188 kilometers) above Earth's surface.
Is time Travelling possible?
In Summary: Yes, time travel is indeed a real thing. But it's not quite what you've probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second.
