Are wormholes real?
Wormholes are shortcuts in spacetime, popular with science fiction authors and movie directors. They’ve never been seen, but according to Einstein’s general theory of relativity
, they might exist.
Do we know that wormholes are real?
Has a wormhole ever been created?
What happens if you go through a wormhole?
Has NASA discovered a wormhole?
Is there sound in space?
No, there isn’t sound in space.
This is because sound travels through the vibration of particles, and space is a vacuum. On Earth, sound mainly travels to your ears by way of vibrating air molecules, but in near-empty regions of space there are no (or very, very few) particles to vibrate – so no sound.
How many universes are there?
In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16.
What is the closest black hole to Earth?
In 2020 a team led by European Southern Observatory (ESO) astronomers reported the closest black hole to Earth, located just 1000 light-years away in the HR 6819 system.
Has anyone been in a Blackhole?
Fortunately, this has never happened to anyone — black holes are too far away to pull in any matter from our solar system.
Is time traveling possible?
The simplest answer is that time travel cannot be possible because if it was, we would already be doing it. One can argue that it is forbidden by the laws of physics, like the second law of thermodynamics or relativity. There are also technical challenges: it might be possible but would involve vast amounts of energy.
What do space smell like?
A succession of astronauts have described the smell as ‘… a rather pleasant metallic sensation … [like] … sweet-smelling welding fumes’, ‘burning metal’, ‘a distinct odour of ozone, an acrid smell’, ‘walnuts and brake pads’, ‘gunpowder’ and even ‘burnt almond cookie’.
What is the loudest noise in the universe?
The loudest sound in the universe definitely comes from black hole mergers. In this case the “sound” comes out in gravitational waves and not ordinary sound waves.
What is outside our Universe?
To answer the question of what’s outside the universe, we first need to define exactly what we mean by “universe.” If you take it to mean literally all the things that could possibly exist in all of space and time, then there can’t be anything outside the universe.
Do we live in a multiverse?
We currently have no evidence that multiverses exists, and everything we can see suggests there is just one universe — our own.
How do you destroy a black hole?
Black holes are among the most destructive objects in the universe. Anything that gets too close to a black hole, be it an asteroid, planet, or star, risks being torn apart by its extreme gravitational field.
Will black hole hit Earth?
The possibility that a black hole could actually impact Earth may seem straight out of science fiction, but the reality is that microscopic primordial black holes could actually hit Earth. If one did, it wouldn’t just impact like an asteroid, it’d pass straight through the entire Earth and exit the other side.
What can destroy a black hole?
Black holes are among the most destructive objects in the universe. Anything that gets too close to a black hole, be it an asteroid, planet, or star, risks being torn apart by its extreme gravitational field. By some accounts, the universe may eventually consist entirely of black holes.
How cold is space?
The temperature in outer space is generally 2.73 Kelvin (-270.42 Celsius, -454.75 Fahrenheit). This is actually the temperature of Cosmic Microwave Background Radiation, which is spread throughout the universe.
Does the past still exist?
In short, space-time would contain the entire history of reality, with each past, present or future event occupying a clearly determined place in it, from the very beginning and for ever. The past would therefore still exist, just as the future already exists, but somewhere other than where we are now present.
Do wormholes exist?
Wormholes are shortcuts in spacetime, popular with science fiction authors and movie directors. They’ve never been seen, but according to Einstein’s general theory of relativity, they might exist.
Can u fart in space?
The official verdict on gas in space: No burps, more farts, and no, you can’t use your flatulence to propel you around the shuttle.
