What is your parallel universe?
From science fiction to science fact, there is a concept that suggests that there could be other universes besides our own, where all the choices you made in this life played out in alternate realities. The concept is known as a “parallel universe,” and is a facet of the astronomical theory of the multiverse.
What is an example of a parallel universe?
Some theories about parallel universes are that they have different values for physical constants. There would be some universes where stars can’t form for example. The hyperspace of science fiction is a parallel universe which allows for faster than light travel between two entry points in our universe.
What is the theory of parallel universes?
The multiverse is a theory in which our universe is not the only one, but states that many universes exist parallel to each other. These distinct universes within the multiverse theory are called parallel universes. A variety of different theories lend themselves to a multiverse viewpoint.
Can we travel between parallel universes?
If you are an advocate of a multiple big bang multiverse, then that would mean that leaving our universe to travel to another would be just as impossible as travelling back to the time before the big bang that resulted in our universe even happened. No matter—you’ve worn them both, in two separate parallel universes.
Can you go into a wormhole?
Physicists have worked out a way that it might be feasible to send someone through a wormhole. Wormholes are tunnels between two black holes that connect distant regions of space-time, and normally it would be impossible to pass something through them, but factoring in an extra dimension might make it possible.
How fast can humans travel without dying?
“There is no real practical limit to how fast we can travel, other than the speed of light,” says Bray. Light zips along at about a billion kilometres per hour.
How far can human travel in space?
The record for the greatest distance from Earth has stood for more than four decades. In April 1970, the crew of NASA’s Apollo 13 mission swung around the far side of the moon at an altitude of 158 miles (254 km), putting them 248,655 miles (400,171 km) away from Earth.
How far have we seen in the universe?
30 billion light-years
What exists in between galaxies?
Gas called the intergalactic medium fills the space between galaxies; the gas of the circumgalactic medium surrounds galaxies more closely. The gas in both places regulates the birth, life and death of the galaxies, and holds a detailed history of the universe. Only lately have astronomers been able to detect it.
Can a planet exist outside a galaxy?
An extragalactic planet, also known as an extragalactic exoplanet, is a star-bound planet or rogue planet located outside of the Milky Way Galaxy. Due to the huge distances to such worlds, they would be very hard to detect directly. However, indirect evidence suggests that such planets may exist.
Is the space between galaxies empty?
Intergalactic space takes up most of the volume of the universe, but even galaxies and star systems consist almost entirely of empty space.
Is there anyone lost in space?
A total of 18 people have lost their lives either while in space or in preparation for a space mission, in four separate incidents. Given the risks involved in space flight, this number is surprisingly low. The two worst disasters both involved NASA’s space shuttle.
Is it dark in deep space?
Above the Earth’s atmosphere, outer space dims even further, fading to an inky pitch-black. And yet even there, space isn’t absolutely black. The universe has a suffused feeble glimmer from innumerable distant stars and galaxies. This artist’s illustration shows NASA’s New Horizons spacecraft in the outer solar system.
Why do you not see stars in space?
In space, or on the moon, there’s no atmosphere to spread the light around, and the sky will appear black at midday – but that doesn’t mean it’s not just as bright. Even in space, stars are relatively dim, and simply don’t produce enough light to show up in photos set for bright sunlight.
