In general relativity, spacetime can be curved but can never be torn, because in GR, topology of spacetime can't change, only geometry can change.
That connection led to the creation of a model that proposes that spacetime can be created or destroyed by changing the amount of entanglement between different surface regions of an object.
Large objects such as the Sun and planets aren't the only masses that warp the fabric of space-time. Anything with mass—including your body—bends this four-dimensional cosmic grid. The warp, in turn, creates the effect of gravity, redirecting the path of objects that travel into it.
While black holes are mysterious and exotic, they are also a key consequence of how gravity works: When a lot of mass gets compressed into a small enough space, the resulting object rips the very fabric of space and time, becoming what is called a singularity.
In their paper, the authors consider a hypothetical example with w = −1.5, H0 = 70 km/s/Mpc, and Ωm = 0.3, in which case the Big Rip would happen approximately 22 billion years from the present. In this scenario, galaxies would first be separated from each other about 200 million years before the Big Rip.
We know the observable universe — the part we can visibly see and measure — began around 13.8 billion years ago with the Big Bang. So we know the age of the universe is finite at least from the time of the Big Bang.
Since in the observer's frame they are stationary and the Sun is moving, the conclusion is that velocity does not change the spacetime curvature. Incidentally, this is why a fast moving object does not turn into a black hole. Save this answer.
Electric charges and magnets are manifestations of certain types of matter, most particularly electrons. Since matter carries energy (via Einstein's famous relation that energy is mass times the speed of light squared), such objects will have a gravitational field and so they will distort space-time.
1 second in space is equal to 1 second in earth. Space time doesn't move any faster than earth time so we use earth time for all of outer space.
In order for you to stop time, you would have to be traveling infinitely fast. Nothing can travel faster than light (let alone infinitely fast) without gaining infinite mass and energy, according to Einstein's theory of relativity.
Gravity is the curvature of spacetime
It is here that Einstein connected the dots to suggest that gravity is the warping of space and time. Gravity is the curvature of the universe, caused by massive bodies, which determines the path that objects travel. That curvature is dynamical, moving as those objects move.
The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation, where one hour on the distant planet equals 7 years on Earth.
The “gravitational memory effect” predicts that a passing gravitational wave should forever alter the structure of space-time. Physicists have linked the phenomenon to fundamental cosmic symmetries and a potential solution to the black hole information paradox.
Historical origin
Many people link space-time with Albert Einstein, who proposed special relativity in 1905. However, it was Einstein's teacher, Hermann Minkowski, who suggested space-time, in a 1908 essay.
It is said that in order for an object or a projectile to leave Earth's gravitational pull, it must reach Earth's escape velocity, meaning reach a speed of 7 miles per second(~11 km per second). The speed needed for Apollo 11 to break free of the Earth's gravitational field was about 7 miles per second.
So, according to de Rham, the only thing capable of traveling faster than the speed of light is, somewhat paradoxically, light itself, though only when not in the vacuum of space. Of note, regardless of the medium, light will never exceed its maximum speed of 186,282 miles per second.
Only in the LabIn everyday circumstances, an object cannot travel faster thanlight. The Princeton experiment and others change these circumstancesby using devices such as the cesium chamber rather than a vacuum.
According to theoretical physicist Carlo Rovelli, time is an illusion: our naive perception of its flow doesn't correspond to physical reality. Indeed, as Rovelli argues in The Order of Time, much more is illusory, including Isaac Newton's picture of a universally ticking clock.
Because of its close proximity to the black hole, it experiences tremendous time dilation, with one hour on the faraway planet equaling seven years on Earth.
How much time on earth is 1 hour in space? Around eight minutes and twenty seconds. You should do the math for one minute.
Eventually, the entire contents of the universe will be crushed together into an impossibly tiny space – a singularity, like a reverse Big Bang. Different scientists give different estimates of when this contraction phase might begin. It could be billions of years away yet.
The overwhelming majority of the Universe will not be consumed by black holes, but rather flung into intergalactic space. Once there, they will wander the Universe as "runaway stars" (or stellar remnants) for as long as the Universe still exists.
If the Universe holds enough matter, including dark matter, the combined gravitational attraction of everything will gradually halt this expansion and precipitate the ultimate collapse. Over time, galaxies, then individual stars, will smash into each other more frequently, killing off any life on nearby planets.
