Can the fabric of space be ripped?
Einstein’s general relativity says no, the fabric of space cannot tear.
In fact, the realization that quantum physics leads to violent short-distance undulations led some to speculate that rips and tears might be a commonplace microscopic feature of the spatial fabric..
Why is time the 4th Dimension?
“Time is ‘separated’ from space in a sense that time is not a fourth dimension of space. Instead, time as a numerical order of change exists in a 3D space. Our model on space and time is founded on measurement and corresponds better to physical reality.”
Can you breathe in space?
But inside the International Space Station (ISS), the American astronauts and Russian cosmonauts do breathe air almost identical to the stuff we breathe down here on planet Earth – same pressure and about 80 per cent nitrogen and 20 per cent oxygen. … It turns out they get it by ‘splitting’ H2O with electricity.
Is it possible to travel back in time?
The Short Answer: Although humans can’t hop into a time machine and go back in time, we do know that clocks on airplanes and satellites travel at a different speed than those on Earth. … However, when we think of the phrase “time travel,” we are usually thinking of traveling faster than 1 second per second.
Does time exist without space?
Special & General Relativity Questions and Answers General relativity tells us that what we call space is just another feature of the gravitational field of the universe, so space and space-time can and do not exist apart from the matter and energy that creates the gravitational field.
Is time and space the same?
What Is Time? Back in the 1800s, there was space and there was time. … But there was no notion that space and time were in any sense “the same thing”. But then along came Einstein’s Special Theory of Relativity—and people started talking about “spacetime”, in which space and time are somehow facets of the same thing.
Can a black hole kill you?
The point at which tidal forces destroy an object or kill a person will depend on the black hole’s size. … For small black holes whose Schwarzschild radius is much closer to the singularity, the tidal forces would kill even before the astronaut reaches the event horizon.
How is space like a fabric?
In Einstein’s theory, space and time are aspects of a single measurable reality called space-time. … We can think of space-time as a fabric; The presence of large amounts of mass or energy distorts space-time – in essence causing the fabric to “warp” – and we observe this warpage as gravity.
Is time really a dimension?
There’s a fourth dimension that’s just as important, even though it’s very different: time. We’re always moving forward through time, sure, but it’s just as much a dimension as any of the spatial ones. … But even two different objects with the same exact three-dimensional spatial coordinates might not overlap.
How many dimensions do we live in?
In everyday life, we inhabit a space of three dimensions – a vast ‘cupboard’ with height, width and depth, well known for centuries. Less obviously, we can consider time as an additional, fourth dimension, as Einstein famously revealed.
Can space be created?
No. And nor is energy. Energy is the one thing we can neither create nor destroy, and it seems to be intimately related to what space is. But nevertheless the stress-ball does get bigger as the pressure reduces, so it’s reasonable to say space is “created”.
Is space made of dark matter?
It turns out that roughly 68% of the universe is dark energy. Dark matter makes up about 27%. The rest – everything on Earth, everything ever observed with all of our instruments, all normal matter – adds up to less than 5% of the universe.
What is the fabric of space made from?
The fabric of spacetime fabric is not made of energy, particles , photons or any other physical entities. The space is made of nothing and time mostly indicates change. Advocates of the fabric of spacetime also say that it behaves like solid ‘structure,but no structure’.
Is space a material thing?
Space in our Universe is three dimensional, and when you combine it with time, you get a four dimensional quantity. When it comes to the notion of spacetime curvature, this is what General Relativity refers to. But under no circumstances should you conceive of space as though it’s a material, physical thing; it isn’t.
Can we see spacetime?
In physics and, more generally, in the natural sciences, space and time are the foundation of all theories. Yet we never see spacetime directly. Rather we infer its existence from our everyday experience.
What does space smell like?
Astronaut Thomas Jones said it “carries a distinct odor of ozone, a faint acrid smell…a little like gunpowder, sulfurous.” Tony Antonelli, another space-walker, said space “definitely has a smell that’s different than anything else.” A gentleman named Don Pettit was a bit more verbose on the topic: “Each time, when I …
How much time on earth is 1 hour in space?
0.0026 secondsThat number times 1 hour is 0.0026 seconds.
Is empty space empty?
Space is not empty. A point in outer space is filled with gas, dust, a wind of charged particles from the stars, light from stars, cosmic rays, radiation left over from the Big Bang, gravity, electric and magnetic fields, and neutrinos from nuclear reactions.
