Skydiver aims to break sound barrier in free fall

[3870x2]

They were pretty accurate on everything except for the longest free fall time, where they were off by more than 1 minute, or about 22%

Isn't gravity much lighter at 400,000 feet? The diver can control the speed of his descent by positioning his body, like Felix.

Things that burn up in our atmosphere are already going fast. The burn wouldnt kill you, the 7200 mp/h windspeeds would do you in before that.

The Gravity is pretty much the same. It might be .1% lighter than on the surface. The big difference is the pressure. Closer to the earth you will have a huge amount of atmosphere above you, obviously. Diving 33 meters under water would be the same pressure increase as going from 120k feet to the ground.

regardless without shielding you will be killed

Why? A lot of people given the chance to do this would have. I would have in a second. This guy isn't a god. Hes just lucky as hell they picked him.

You have to take it in context; (I know it was sprawling and hard to keep track of; all 16 words) he said "This guy is a god. He knows how to do a proper leap of faith" which, was funny but now its murdered...

New thought: Drone always finds the awesome pics.

My guess would be...

AAAAAAAAAAHHHHHHHHHHHHHHHH!!!

But at 800MPH.

i cant stop crying now from laughing so hard

So I just read that gravity continues on forever. That is not nearly as astonishing as the fact that at 250 miles away from the earth, the gravity is still at 90% of its full force. When you are in space, you are not weightless, you are in free fall, along with other objects (In other words, you are falling not towards earth, but around earth, as are all the objects around you).

Gravity can be felt tens of thousands of miles away from earth.

This may or may not be common knowledge for all, but to me it was a surprise.

I had always figured gravity kind of ended quickly somewhere not too much farther than Felix took his jump (IE like 200,000 feet or something)

Interesting that I can grasp Quantum physics, String theory, etc.. But something like this has escaped me for so long.

I love this stuff.

Gravity is pretty cool; one of the most basic, least understood concepts. Its been proposed that, unlike light and everything else we know of, it may not have a speed limit; i.e., the speed of gravity is infinite, even across the universe. Although at any distance it gets to be very minute

There is no way to test that theory unless you could create a huge object out of thin space and measure its gravity from very far away. So for all intents and purposes, Gravity's speed doesn't matter.

 

[Irony]

Yeah, theres always some excuse for every good theory, lol. The cost to create an artificial star would probably be prohibitive

There are four forces in nature. Weak, Strong, Electromagnetic and Gravitational Force.

Weak and Strong forces work only for "shortest" distances (atomic and subatomic scale). While electromagnetic force/waves (light, radio, microwaves, T-rays, X-rays, gamma rays) and gravity work for all distances and propagate with the speed of light.

Interesting that I can grasp Quantum physics, String theory, etc.. But something like this has escaped me for so long.

Quantum physics can explain only weak, strong and EM forces. While general relativity works with gravity. To understand and describe all four forces scientists need quantum gravity, that'd be their Holy Grail.
