What is the last point of space?

In the 1900s, Hungarian physicist Theodore von Kármán determined the boundary to be around 50 miles up, or roughly 80 kilometers above sea level. Today, though, the Kármán line is set at what NOAA calls “an imaginary boundary” that's 62 miles up, or roughly a hundred kilometers above sea level.

Where does Earth's gravity end?

The Earth's gravitational field extends well into space it does not stop. However, it does weaken as one gets further from the center of the Earth. The Shuttle orbits about 125 mi above the surface, roughly the distance between Jackson and Nashville!

Does the universe have an end?

The universe, being all there is, is infinitely big and has no edge, so there's no outside to even talk about. Oh, sure, there's an outside to our observable patch of the universe. The cosmos is only so old, and light only travels so fast. The current width of the observable universe is about 90 billion light-years.

Is the Big Rip real?

Overview. The truth of the hypothesis relies on the type of dark energy present in our universe. If −1 < w < 0, the expansion of the universe tends to accelerate, but the dark energy tends to dissipate over time, and the Big Rip does not happen.

Is space hot or cold?

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). But space is mostly full of, well, empty space. It can't move at all.

The observable universe is finite in that it hasn't existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding). The observable universe is centred on us.
