What is beyond outerspace?
If by outer space you mean all that surrounds the Earth and stretches into all directions as far as people can see, then you’re talking about what astrophysicists call the universe.
For there to be anything outside of the universe supposes that it has an edge, which is a problematic supposition for physicists..
What will happen to our galaxy in 4 billion years?
The Milky Way is on track to collide and merge with its nearest neighbor, the Andromeda galaxy, in about 4 billion years. The galaxies will pass through each other, get snapped back together by gravity, and eventually merge cores. NASA illustrations show what the arrival of an entire galaxy of stars will look like.
Will the Earth die?
However, the long-term trend is for plant life to die off altogether. … By that point, all life on the Earth will be extinct. The most probable fate of the planet is absorption by the Sun in about 7.5 billion years, after the star has entered the red giant phase and expanded beyond the planet’s current orbit.
What is the smallest thing in the universe?
An atom is the smallest unit of any element in the periodic table. … Experiments found that each atom has a tiny, dense nucleus, surrounded by a cloud of even tinier electrons. The electron is, as far as we know, one of the fundamental, indivisible building blocks of the universe.
Will the Milky Way ever die?
A new study shows that the Milky Way galaxy is currently in its second life, having previously died over a 10 billion year time period. … After around three billion years or so of these alpha process supernovae, shock waves started to heat the gases up to warmer temperatures.
Where does the Milky Way galaxy end?
Two billion years from now, the Milky Way and Andromeda, our closest neighboring galaxy, will begin to fuse into one giant football-shaped galaxy.
Where can I see the Milky Way tonight?
Generally the dense part of the Milky Way is best viewed when it is as high as possible in the Southern sky. Facing south during April and May the pre-dawn hours are best. From June to early August the best time is near midnight, though the Milky Way will be visible almost all night.
Is the Milky Way moving?
The Milky Way does not sit still, but is constantly rotating. As such, the arms are moving through space. The sun and the solar system travel with them. The solar system travels at an average speed of 515,000 mph (828,000 km/h).
What is the biggest thing in the universe?
The biggest supercluster known in the universe is the Hercules-Corona Borealis Great Wall. It was first reported in 2013 and has been studied several times. It’s so big that light takes about 10 billion years to move across the structure. For perspective, the universe is only 13.8 billion years old.
What happened to Theia?
Computer simulations suggest that Theia was traveling no faster than 4 km/s (8,900 mph) when it struck Earth at an estimated 45 degree angle. … In contrast, evidence published in January 2016 suggests that the impact was indeed a head-on collision and that Theia’s remains can be found in both the Earth and the Moon.
How many dead bodies are floating in space?
However, of the roughly 550 people who have so far ventured into space, only three have actually died there. Bringing the universe to your door.
How do galaxies die?
The process repeats: Gravity condenses gas into galaxies and stars, stars blow up and kick the gas out, gravity cycles the gas back in and makes new stars. … Without gas, it can’t form new stars; the old stars live out their lives and die, and eventually the galaxy dies too.
How long will the Milky Way last?
about 4.5 billion yearsThe Milky Way and the Andromeda Galaxy are on a collision course, and in about 4.5 billion years, they will meet. Now astronomers using the Hubble have provided some visual insight into what that collision might look like.
Will we die when Andromeda collides?
Four billion years from now, our galaxy, the Milky Way, will collide with our large spiraled neighbor, Andromeda. The galaxies as we know them will not survive. In fact, our solar system is going to outlive our galaxy. … Currently, Andromeda and the Milky Way are about 2.5 million light-years apart.
What’s the heaviest thing on earth?
The heaviest object ever directly weighed was the Revolving Service Structure (RSS) of launch pad 39B at NASA’s Kennedy Space Center, Florida, USA. The structure was lifted up on 21 jacking points which, between them, measured the mass of the RSS as 2,423 tonnes (5,342,000 lbs).
Are the Milky Way and Andromeda going to collide?
The monster collision between our Milky Way and fellow spiral galaxy Andromeda will occur about 4.5 billion years from now, according to the new research, which is based on observations made by Europe’s Gaia spacecraft.
Is the Milky Way galaxy in a void?
Astronomers have previously noticed that the Milky Way sits in a large, flat array of galaxies called the Local Sheet, which bounds the Local Void. The Local Void extends approximately 60 megaparsecs (200 Mly), beginning at the edge of the Local Group. … This has been called the Local Void or Local Hole.
Does the Galaxy end?
And now, NASA scientists say they know exactly when it will come to an end. In a universe that is forever spreading apart, the Milky Way has been moving closer to celestial neighbor the Andromeda galaxy.
