That's why I said that...
you need air to breathe, who said anything about oxygen...
I like this thread.
You need air with at least 12 or 14 percent oxygen content I think.
Normal air has 21%, and when you breathe it out, it still has around 14% or so.
the only major problem with this is that time is also slowed down for the observer. When one reaches near the speed of light it appears that they go faster then light.

A little nostalgia in this thread, keep going
Several reasons, one being the Coriolis Effect. Because the earth is spinning, everything airborne in the northern hemisphere will eventually turn to the right, and since balloon travel is dictated by wind, you will never go in a straight line.
Also, the air mass you are in would need to move around the earth with you (24 hours), but it won't. The balloon would instantly need to be exceeding 1000 mph once it lifts off. Have you ever seen a balloon do that?
1. Bullets are made of lead, lead is not magnetic.
2. Bullets are moving so rapidly that any magnet capable of diverting ones course would have to be heavy enough to break your fucking neck when you put it on.
In order for this to work the giant mirror like object would have to already exist. If you had to build one then you could only see as far back as the moment when the light first hit the mirror.
Say it was 10 light years away, and we put it there right now,it would take 10 years to start working, and would only show us a linear timeline begining from when we put the mirror there.
But the real reality of it is we would only be able to see the reflections of stars, as the earth wont give offf enough light to be seen in the mirror. So you would see starts as they were several light years ago. Which we already do.
Though if it took the light from a star 10 light years to reach earth, and the mirrior was also 10 light years away from earth, yet the mirror was 5 light years away from the star, looking directly at the star would show us how it was 10 years ago, looking at the star through the mirror would show us as it was 15 years ago.
The speed of push is much slower than the speed of light.
The speed of push is actually just under the speed of sound. So you're not communicating with someone faster than light, you're communicating with someone slower than sound.
Ignoring the curvature as mentioned, assume that you're on a perfectly flat plane that is infinitely large.
If the rope,which we'll assume is uniform, has a diameter of xcm, and a mass of y kg per m, and that the gravity is z m/s^2.
The further you pull the rope, the more force is required to keep it off the ground. Eventually it will break. Assuming that you have a rope made out of an unbreakable material, you'll eventually require millions of tons of force just to keep it off the ground.
You must be trolling....
the guy on the right is out 10 bucks.
he put 20 in the box and bought it for 30 totaling 50$ out of his pocket, but got 40 dollars from the box.
If you couldnt figure that one out pls gtfo
Little visual aid
no because the first 10 of the 20 lightyears the *light* (picture) would need to travel to the new builded mirror. so it would just not be visible from earth the first 10 years. and then the picture (light) would have to travel back 10 years, so yes you would see yourself 20 years in the past. but not as a baby but as the man at the moment the mirror was created.
slap me if iam wrong.
i dont ... im trying to .. my brain its ...

Opening transaction - putting the money in the box
Guy A: -20
Guy B: -20
second transaction, selling box for 30 bucks
Guy A: 10
Guy B: -50
Third transaction, guy B realizes he has 40 dollars in the box
Guy A: 10
Guy B: -10
are you fucking stupid, the no. 2 guy uses 50 dollar dollar bills, and the other guy uses 20 dollar.
Therefore it is the no. 1 guy getting 10 dollars from the trade, while the other guy gets -10 dollars
Because you can't put enough force through your legs to negate all the momentum gained during your fall. You would hit the ground a bit slower, but not by much.
I hope you are a troll?
Pushing off a chair the same weight as yourself would propel the chair faster downwards as much as it would push you upwards.
If you pushed off of an object the same weight as yourself in space, you would each go flying opposite directions at the exact same speed.
On Earth you would have to factor in gravity but yes, you would indeed hit the ground at a slightly slower speed than if you had not pushed off the chair
Nope. It's the same principle as rocket engines; they expel mass to gain momentum. By pushing the chair downward, you gain upward momentum. It's just a very tiny amount compared to your existing downward momentum.
haven't you heard of conservation of momentum. The masses aren't changing hence the only way for momentum to be conserved if velocity remains constant.
a floor exerts a force on a chair equal to the weight of the chair.
the chair exerts the same force as the person exerts on the chair in this case as well.
Indeed, there is no net force on the system so net momentum does not change. That is to say, MVchair + MVtroll = MVchair' + MVtroll'. Let's say you are both 1 kg for simplicity's sake and were both moving at 10m/s. If you push off at 1m/s, we have this: 10 + 10 = 11 + 9. You are moving slower and the chair is moving faster but the net value is the same. We can set MVchair' + MVtroll' to be anything we like as long as they add up to the original value, and there will be no contradiction.
That anon was very slightly mistaken; the speed of push /is/ the speed of sound. The speed of sound is just the speed of the propagation of a compression wave through a medium, and pushing something /is/ a compression wave.
Visually that is correct, otherwise it is not. The circle would be made up of miniature jagged edges, which by definition is not a circle. Thus, Pi does not equal four.
this is actually a reasonable idea, save for the fact that you wouldn't actually be able to earn enough money to pay for transportation if the amount of money you earnt is even non-negligible. Plus if the difference in gravity would result in any noticeable difference in mass reading on the scales then the scales would most certainly be adjusted for that area
No, weight is a positive number. The force acting on the mass may be negative, but weight is always positive. To say it is negative is to say it "less then exists" which is less then nothing.
Prove me wrong?
