In college I dove into the subject of PHYSICS. Physics is a part of everything in our daily life. My specific point here has to do with weight. (Sorry, not about firearms) it’s about our planet. A simple part of physics that i learned was, if you take weight away from any object it will be easier to push or pull. Now lets talk about our PLANET. I’ve seen on the news again that Space X has sent more satellites up into space. Each piece of equipment that is sent into space weighs something, correct. NASA, and other companies have been doing this for years now. All this material has come from our planet. So, again to the point of PHYSICS, they’ve made our planet lighter. The planets rotate around the sun due to their weight and gravitational pull of the sun. So if our planet is becoming lighter wouldn’t be more easy for the suns gravitational pull to drawl the earth closer and also create temperature to rise? Physics, only saying…
The key concept here is mass, not weight (per se). And no, collectively, the kinds of masses we’re talking about cosmically are grains of sand falling off the back of a supertanker. Our orbit is holy stable from ecological standpont – and thank God. In short, our planet continues to orbit the sun at a relatively stable orbit because it always has (and always will). But our ultimate end lies in winter, not heat…
Well, a lot of the stuff that we send up is on a trajectory that will eventually fall back to earth, thus returning its mass to the planet.
Plus there’s an estimated 100 tons of space rocks and dust falling down on the planet daily
The more concerning thing is the amount of water and concrete that India and china are consuming and moving has begun to cause a shift in earth’s rotation!
Exactly what I was going to say BUT, YOU Said it First…
Like a rock in the tire tread. 
That is called Talent! 
I agree with others. What we are sending up orbiting the earth has no significant effect on the planet’s mass and is a net zero if you consider the mass of earth and the bodies that orbit earth, both natural and man-made. Of course, everything that is man made is, in fact, made from natural elements found on earth.
It’s currently very trendy and a great way to get research dollars if you are going to blame everything on human activity. (It’s all about the clicks, make a crisis, get some clicks carries the day) The geological record shows that entire continents have drifted with little effect to the earth’s rotation. The magnetic poles drift and reverse on a regular cycle. The rotation slows due to the moon’s tidal forces. It’s not all about us.
Agree completely. With all those complaining about global warming, they ignore the fact that there have been multiple cycles of freezing and heating the earth over billions of years with geological proof. What we as humans do today have little effect in the grand scheme of earths rise and fall over the next 100, 1,000, 1,000,000 or more years. The Universe has bigger plans for the third rock from the sun!
Less mass, more speed. More speed changes time continuum and we live longer.
It’s a win-win situation.
We need more satellites and less falling rocks.
The weight of the H2O that evaporates from the oceans and is suspended in the atmosphere is billions of times higher than the satellites in earth orbit.
I think you’d have to look at our mass as a system. The sun’s gravitational pull on us is in sum total of the earth and the debris circling around us, as well as the moon.
“The Sun’s gravity acts on every mass individually in the Earth–Moon–debris system. But when you step back and look at the overall motion of the system, it behaves as if all that mass were concentrated at a single point: the system’s center of mass (barycenter).”
I think I took one physics class in high school and one in college. Not my best grades at that.
I think yours is an interesting question. From what I have seen in my short travels, one of my concerns is pollution, past, present and future, and how we can clean our one and only earth.
But as far as weight, I’m guessing the weight removed from earth could be so small a fraction compared to what is still here.
But, if I may be light hearted, let’s grow more trees, they are heavy, when their leaves fall, it creates more soil, thus adding even more weight. All those trees and soil is bound to create more life/creatures, even more weight.
Lest we forget, plants grow by taking stuff out of the earth, then, they put it back either into the earth or into the atmosphere. It’s a Zero Sum Game…
What I’ve just realized is… that I poop less than I eat.
If we multiply it by 8.1 billion… 
It’s a gigantic Earth weight deficit.
Unless there are more people who can do this:
Sometimes a post is entered to see how many serious folks are around. Straight talk means more to our future. Having fun raises the sole and keeps us willing.
Everyone have a Happy New Year.
Stay alert, keep training.
Cycles are the key to what is going on with the earth. Cold winters then warmer winters. Hotter summers then cooler summers. The distance from the sun alternating. The ice age had come and now we are warming up as the glaciers and ice caps are melting. The form of the water is going from ice and turning into water, but it is just changing and not disappearing. The effects of space junk around the earth have to have some sort of effect but what effect does it have? For where there is an action there has to be an equal reaction, we know that is a fact. Back years ago, people lived easily over 100 years and now if a person lives to 100 it is a rarity. There has been a change in the earth to have this be possible. We as people adapt to the changes but of course with a cost. If the world only had 516 million people in it around the 1600’s and now having 8.24 billion people has to have an effect upon the earth too. 600 years ago, the world was flat and 120 years ago man just learned to fly then around 50 years ago man landed on the moon. How much do we not know?
Albeit off topic, anyone heard of temps rising in Maine winters? Saw a mini documentary about recent winters compared to several years ago in Maine.
Allegedly, the average temps there have risen to a point where the winters have not been cold or snowy enough to kill off most of the ticks.
So the ticks infest the moose so much there, it’s killing the moose slowly inhumanely - the story went. Not a fan of ticks getting on me. So far, two summers in a row, I brought some home, ouch.
Any validity?
