Why we might be alone in the universe?
Why does it appear, that humanity is the lone intelligence in the universe? The answer might be that planet Earth is more unique than we’ve previously assumed. The rare earth hypothesis posits exactly this – that a range of factors made Earth exceptionally unusual and uniquely able to produce intelligent life.
What is out there in space?
Outer space is not completely empty—it is a hard vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium, as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays.

Kepler-452b (a planet sometimes quoted to be an Earth 2.0 or Earth’s Cousin based on its characteristics; also known by its Kepler Object of Interest designation KOI-7016.01) is a super-Earth exoplanet orbiting within the inner edge of the habitable zone of the Sun-like star Kepler-452, and is the only planet in the …
Is Earth the only planet with life?
Earth is the only planet in the universe known to possess life. The planet boasts several million species of life, living in habitats ranging from the bottom of the deepest ocean to a few miles into the atmosphere. And scientists think far more species remain to be discovered.
How many Earths are in the universe?
“As many as six billion Earth-like planets in our galaxy, according to new estimates.” ScienceDaily. ScienceDaily, 16 June 2020.
Does the universe go on forever?
In the absence of dark energy, a flat universe expands forever but at a continually decelerating rate, with expansion asymptotically approaching zero; with dark energy, the expansion rate of the universe initially slows down, due to the effects of gravity, but eventually increases, and the ultimate fate of the universe …
Are there many Earths?
On November 4, 2013, astronomers reported, based on Kepler space mission data, that there could be as many as 40 billion Earth-sized planets orbiting in the habitable zones of Sun-like stars and red dwarf stars within the Milky Way Galaxy.
What’s the most powerful thing in the universe?
Quasars inhabit the centers of active galaxies and are among the most luminous, powerful, and energetic objects known in the universe, emitting up to a thousand times the energy output of the Milky Way, which contains 200–400 billion stars.
What is the weakest thing in the universe?
Actually, gravity is the weakest of the four fundamental forces.
What is the hardest thing in the universe?
Nuclear pasta
What is the most violent event in the universe?
Thousands of times more energetic than ordinary exploding stars, their visible light as bright as a million galaxies, gamma-ray bursts are the most violent events in the universe, and radiation from one of these events reaches the vicinity of Earth at a rate of about one a day.
How violent is space?
Space can be a violent place. Asteroids and comets slam into planets, stars explode – or they are ripped apart by black holes. But in terms of scale, perhaps nothing is as violent as the collisions between huge clusters of galaxies. When one cluster gets too close to another, their mutual gravity yanks them together.
What explosion created the universe?

How cold is deep space?
It will quickly tumble below zero and keep going until it reaches -454.67° F (-270.43° C). While that’s pretty dang cold, it’s not absolute zero, the coldest possible temperature. To reach that numbing number we’ll need to keep going to -459.67° (-273.15° C).
What is the hottest temperature ever made by man?
9.9 trillion degrees Fahrenheit
How cold does Pluto get?
-375 to -400 degrees Fahrenheit
Why did Pluto disappear?
Answer. The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. It contains the asteroid belt as well as the terrestrial planets, Mercury, Venus, Earth, and Mars.
Has anyone went to Pluto?
The only spacecraft to visit Pluto is NASA’s New Horizons, which passed close by in July 2015.
How hot or cold is Pluto?
-387 to -369 Fahrenheit
Can we live on Pluto?
It is irrelevant that Pluto’s surface temperature is extremely low, because any internal ocean would be warm enough for life. This could not be life depending on sunlight for its energy, like most life on Earth, and it would have to survive on the probably very meagre chemical energy available within Pluto.
What is the hottest planet?
Venus
Is Pluto still in our solar system?
According to the International Astronomical Union, the organization charged with naming all celestial bodies and deciding on their statuses, Pluto is still not an official planet in our solar system. Soon after Pluto was discovered in 1930, it was designated a planet, the ninth in our solar system.
