If gravity were too strong, it could cause celestial bodies to collapse into black holes, preventing the formation of stable orbits and potentially leading to a universe devoid of planets and life. Conversely, if gravity were too weak, galaxies and stars might not form properly, leading to a fragmented universe where matter is dispersed and unable to coalesce into the structures necessary for life. In either scenario, the conditions required for life as we know it would likely be impossible, fundamentally altering the nature of the universe.
The orbits of the planets would all be much larger if the sun had less gravity. They might even just fly off free.
Gravity is essential for keeping us grounded on the Earth, enabling objects to have weight, and keeping our planet and solar system in balance. It also plays a crucial role in important phenomena such as tides, orbits, and the formation of galaxies. Without gravity, life as we know it would not exist.
That possibility has been considered before. The basic idea is that the Universe collapses due to gravity, and then expands again in the next Big Bang. However, there are several problems with that. For one, the Second Law of Thermodynamics would still apply. In other words, the next universe would be different from the current one, and the cycle could not continue forever. (Note: If you want to understand astronomy, a basic understanding of the Second Law is a must.) Also, this is not supported by observational evidence. For this to happen, the expansion of the Universe would have to slow down over time. The opposite is actually happening: the expansion of the Universe is accelerating.
If the speed of light traveled at the speed of sound, our entire perception of the universe would drastically change. The fast travel and instant communication enabled by the speed of light would no longer be possible, leading to a significant impact on technology, communication, and our understanding of the cosmos. The universe would appear much different to us due to the altered timeframes and distances involved.
astrophysicists can calculate what would happen to objects, based on mass, in space because of what happens here on earth; however, this actually work when you get to space. things don't behave the way they should. One explanation is that we just don't understand gravity as well as we think we do, but it is more likely that it is due to dark matter.when you do the calculations with extra mass in the universe it all works fine. another good explanation for gravity is when astrophysicists calculate how much mass there is in the universe there just isn't enough stuff! plus the fact that there is really high levels of gravity in some places in space but we can't see anything there we just say it is this dark matter and seen as it cannot be disproved we just have to except it!
If the gravity on the moon decreased significantly, it would have minimal impact on Earth. The pull of Earth's gravity on the moon would still remain unchanged, and our planet's atmosphere, oceans, and ecosystems would continue to function normally.
Without gravity, there would be no largescale structure to the universe. If it simply stopped existing, the moon would fly off from earth orbit; the earth and planets would fly away from the sun into deep space, and not only would the solar system dismantle itself but so would the galaxy. Also, the atmosphere would drift off into space, as would (the shortly thereafter dead) human race, and everything else not fixed to the surface of the planet. However, gravity is very much built into the universe - the structure of the universe is based on it being there (and having the relationship with other fundamental forces that it does). It's a very hypothetical question - the thought that you could "lose" gravity but keep everything else in the universe somehow well-behaved.
No! Of course, there is so much mass that the force of gravity overwhelms everything else in the Universe. Oops, I meant "yes".
The orbits of the planets would all be much larger if the sun had less gravity. They might even just fly off free.
Weight is a function of gravity. Gravity is determined by proximity to mass. At the point of the big bang, all the mass of the universe (which is said to be infinite) was compressed to a single point. Therefore the pull of gravity, and thus the weight of that mass would also be infinite.

Yes, gravity is the weakest of the four fundamental forces in the universe. It is much weaker than the electromagnetic force and the strong and weak nuclear forces.
Everything can be affected by gravity, it just needs to be close enough. Even light can be affected by gravity! But I'm not much of a science person, so if you want a more detailed answer, better ask an expert ^^
By definition, asteroids tend to small objects, Being small they have little or no attraction to or from other asteroids. Gravity only comes into play for much larger objects.
Pretty much nothing. The overwhelming gravitational effect that we feel is from the Earth, and that'd remain the same no matter what happened to the Sun.
