What if Earth's gravity was similar to Venus'?

Venus, the second planet from the sun, has a surface gravity of 8.87 m/s² (29.03 ft/s²), which is about 90% of Earth's gravity. Now imagine what would be like if our planet Earth's gravity was similar to Venus', with a surface gravity of 9 m/s² (29.53 ft/s²). Let's delve into the implications.<br><br>**Effects on the Body**<br><br>* Humans, shoes, buildings, and bridges wouldn't weigh much less than they do on our current Earth. A person who weighs 70 kg (154 lbs) on our current Earth would weigh only about 6-7 kg (13-15 lbs) less on an Earth with Venus-like gravity. In the grand scheme of things, that's not too much.<br>* You might be able to jump slightly higher and your bones would be slightly less dense. But these differences wouldn't be dramatic enough to be immediately noticeable.<br>* Children and teenagers would grow slightly taller on average, because their bones and joints bear less weight. However, this difference would be too small to be noticeable without scientific instruments.<br><br>**Effects on the Environment**<br><br>* Because the atmosphere is slightly less dense due to the weaker gravitational pull, there might be slightly more meteors and slightly more comets coming close to our planet. However, Venus-like gravity is still strong enough to prevent the atmosphere from being slowly stripped away by solar winds.<br>* There would be slightly less erosion in rivers, slightly less wave action in oceans, and slightly less weathering of rocks. With slightly weaker gravity, the ocean tides would be slightly weaker and the atmospheric circulation patterns might be slightly different, resulting in slightly different global and local weather. These differences would be too small to be immediately noticeable without scientific instruments.<br>* Mountains and volcanoes could rise slightly higher before collapsing under their own gravity, because gravity is weaker. But the difference would be too small to be noticeable without scientific instruments.<br><br>**Effects on Technology**<br><br>* The escape velocity from the Earth's surface would be lower. At a gravity of 9 m/s² (29.53 ft/s²), the escape velocity would be about 10.5 km/s (6.52 mi/s). The current escape velocity is 11.2 km/s (6.96 mi/s). This would make it about 7% easier to get to orbit, and slightly more difficult to go beyond orbit into deep space.<br>* The weaker gravity might make it slightly easier to build extremely tall structures, like skyscrapers or bridges, or to construct extremely long tunnels. However, the difference would be too small to be immediately noticeable without scientific instruments.<br>* There would be slightly higher average speeds in the atmosphere due to the effect of gravity on the atmospheric pressure and temperature lapse rate. There could be slightly more lightning. These differences would be too small to be noticeable without scientific instruments.<br><br>**Conclusion**<br><br>If Earth's gravity were similar to Venus', the impact on our daily lives, the environment, and technology would be minimal. The main difference would be a slightly greater ease in escaping the Earth's atmosphere, which could have implications for space exploration.
