What is beyond the space?
Astronomers think space outside of the observable universe might be an infinite expanse of what we see in the cosmos around us, distributed pretty much the same as it is in the observable universe.
After all, it doesn’t make sense that one section of the universe would be different than what we see around us..
How far does the universe go?
30 billion light-years awayToday, the most distant objects we can see are more than 30 billion light-years away, despite the fact that only 13.8 billion years have passed since the Big Bang. The farther a galaxy is, the faster it expands away from us and the more its light appears…
Does Infinity exist in reality?
Although the concept of infinity has a mathematical basis, we have yet to perform an experiment that yields an infinite result. Even in maths, the idea that something could have no limit is paradoxical. For example, there is no largest counting number nor is there a biggest odd or even number.
Are there any humans lost in space?
A total of 18 people have lost their lives either while in space or in preparation for a space mission, in four separate incidents. Given the risks involved in space flight, this number is surprisingly low. The two worst disasters both involved NASA’s space shuttle.
Does space have a smell?
As it turns out, space actually does have a distinct odor. … Astronauts returning from space claim that their suits smell, in a word, burnt. The lingering scent of space is “acrid” and “metallic,” reminding the astronauts of charred meat or welding fumes.
Can Hubble see the moon?
The Hubble telescope is known for its views of faraway galaxies, distant planets, dying stars, and black holes. … Since ultraviolet light is blocked by gases in the Earth’s atmosphere, ground-based telescopes can’t use it to observe the lunar surface.
Is space and time infinite?
Space and time, then, are truly and positively infinite, despite the protest of the imagination. … Professor Pickering says: “If it is difficult for us to imagine infinite space, it is still more so to comprehend infinite time.
Does space ever stop?
In theory space goes on and on… It’s because of the shape of space. Our part of space, or the observable universe, has a special shape: it is flat. That means if you and a friend each had your own rocket ship and you both took off and travelled in a straight line, forever and forever, you would never meet.
How cold is space?
Hot things move quickly, cold things very slowly. If atoms come to a complete stop, they are at absolute zero. Space is just above that, at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit).
Do things exist when not observed?
An item truly exists only as long as it is observed; otherwise, it is not only meaningless but simply nonexistent. The observer and the observed are one.
Where does space 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.
