The earth and the universe are in a free fall, thus giving people the appearence of weightlessness in space. If we are falling is there any chance of us hitting the bottom of this vast universe?

An object orbiting another in space can be considered to be in freefall around the center object. You have probably heard someone explaining circular motion like that of an astronaut or space station or the moon as being in freefall towards the earth. It's a balancing act between the gravity between the two objects (causing the free fall) and the inertia of the planets, moons, satelites, etc that keep them moving in a direction perpinduclar to the inward falling direction.
Eventualy the orbiting object will have to fall toward the center object or away from it, debending on whether the inertia or the gravity is stronger.
Our moon is moving away from us.
All the stars in the galaxy are moving around the center of the galaxy and all the galaxies are moving around the center of the universe but we will never fall in because not only is the universe still expanding, the rate at which all the galaxies are moving away from the center of the universe is getting faster.

What are you talking about? Who told you the universe and earth are in freefall? The reason we experience weightlessness in space is because we are far enough away from any mass to not be affected by any gravitational field. There's no need to over complicate things.
And as for reaching the bottom of the universe, what bottom of the universe? It doesn't have a bottom, the universe is a weird shape that cant be drawn or described except mathematically and so there is no 'bottom'.

sure interior the long-term a decrease valued dollar would be extra clever for our financial equipment than an truly sturdy one. i comprehend you do not have faith that yet a decrease fee dollar will gas American manufacture and upload employment. average you will get pertaining to to the comparable on your dollar as you do now. The intense fee of the dollar replace into between the best factors interior the shortcoming of producing. while products could be imported extra low-value than they may be made then ultimately your financial equipment will falter as ours is . we've tanked.

lol well first of all thew reason for weightlessness is not fallling in space but beacause of the lack of gravity and air to keep you down. this is one of those questions we will never kno unless it happens in theory the universe is neverending, which is really mind boggling if you think about it.

The Earth isn't in freefall, it's in orbit: Earth orbiting sun, Sun orbiting Galactic Center.
It's just that the Sun's orbit takes a really, really, REALLY long time.

We're at the bottom now, havent you seen Jerry Springer latly?

i'm not even going to begin to explain this to someone that doesn't have a clue as to the nature of the universe

no there is no chance. the universe is continually expanding so we will never reach its bottom

THINK DIMENTIONALLY AND LINEARLY, UNIVERSE DOESN'T HAVE ANY TOP OR BOTTOM SO BASICALLY WE CANNOT FALL DOWN OR LIFT AT SOME POINT CAUSE THERE IS NO GRAVITY.
CHEERS
