Does space ever end?
No, they don't believe there's an end to space. However, we can only see a certain volume of all that's out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn't had time to reach us yet, so we have no way of knowing such a galaxy exists.What happens when you reach the end of the space?
It will expand forever; the galaxies within groups and clusters will merge together to form a giant super-galaxy; the individual super-galaxies will accelerate away from one another; the stars will all die or get sucked into supermassive black holes; and then the stellar corpses will get ejected while the black holes ...How long until space ends?
It's Space Day, but traveling the vast entity that is space would take far longer than a single day. The nearest galaxy: 749,000,000 (that's 749 million) years. The end of the known universe: 225,000,000,000,000 years (that's 225 trillion) years.What is the last point of space?
The final layer of the atmosphere, the enormous exosphere, continues until around 6,700 miles (10,000 km) above the surface of our planet (and some say even further). At that point, the moon is still hundreds of thousands of miles away.How far does space go on for?
The observable universe can even be measured. It is 93 billion light years from one side to the other. Now that's a distance even astronomers find hard to think about. It's like making about 300,000 laps of our Milky Way Galaxy, yet our Sun has made only 20 laps in its entire life.What's At The End Of The Universe?
How cold is it in space?
The Cosmic Background Explorer (COBE) satellite has refined temperature measurements taken way back in 1964. According to data from the Cosmic Background Explorer (COBE) satellite, the temperature of space is 2.725K (2.725 degrees above absolute zero).What does 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'.Does space have a bottom?
The universe has a bottom. That bottom extends infinitely outward and has an infinite sky above it, with an infinite number of stars and galaxies. The bottom is remarkably terrestrial, with gravity, mountains, lakes, forests, and sunshine, each of which deserves additional discussion.Is time Travelling possible?
Yes, time travel is indeed a real thing. But it's not quite what you've probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second. And there are important reasons why we need to understand this real-world form of time travel.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.Will humanity ever leave the galaxy?
The technology required to travel between galaxies is far beyond humanity's present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.How long will the Earth last?
The upshot: Earth has at least 1.5 billion years left to support life, the researchers report this month in Geophysical Research Letters. If humans last that long, Earth would be generally uncomfortable for them, but livable in some areas just below the polar regions, Wolf suggests.What is inside a black hole?
The singularity at the center of a black hole is the ultimate no man's land: a place where matter is compressed down to an infinitely tiny point, and all conceptions of time and space completely break down. And it doesn't really exist.What year will the universe end?
22 billion years in the future is the earliest possible end of the Universe in the Big Rip scenario, assuming a model of dark energy with w = −1.5. False vacuum decay may occur in 20 to 30 billion years if the Higgs field is metastable.Will universe expand forever?
There is a strong consensus among cosmologists that the shape of the universe is considered "flat" (parallel lines stay parallel) and will continue to expand forever.What's on the other side of space?
A. If space is infinite, there is nothing on the other side. If space is finite because it has been bent around upon itself because of gravity, then again there is nothing on the other side of it because there is no seam.Does the past 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.Is time an illusion?
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.Can a wormhole exist?
In the early days of research on black holes, before they even had that name, physicists did not yet know if these bizarre objects existed in the real world.Can you fall in space?
In space, no kicking and flailing can change your fate. And your fate could be horrible. At the right angle and velocity, you might even fall back into Earth's atmosphere and burn up. That's why NASA has protocols that it drills into astronauts for such situations.Is the earth upside down in space?
“As far as we astronomers can tell, there really is no 'up' or 'down' in space,” he says. So the answer to the question of which way up is the Earth is simple: it is not any particular way up and there is no good reason other than a historical superiority complex to think of north as being the top of the world.Is everything in space falling?
Everything in space, including the International Space Station, is essentially in free fall, falling rapidly under the force of (almost) nothing but gravity. But most objects aren't quite in literal free fall. Lots of things can give satellites and other space objects tiny pushes in one direction or another.Can you 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.Will a body decay in space?
In space we can assume that there would be no external organisms such as insects and fungi to break down the body, but we still carry plenty of bacteria with us. Left unchecked, these would rapidly multiply and cause putrefaction of a corpse on board the shuttle or the ISS.Is space completely silent?
OK so wait, is space completely silent or not? While space is more silent than you could ever imagine, it's not completely devoid of sound. Sound waves cannot travel through space, but there are some infinitesimally small regions where sound can exist, under very specific conditions.
