Probably the planets would stop going around the sun and start going around the earth and if the earths gravity was that strong there wouldn't be life because we would all die from the gravitational pressure.
The earth's water would evaporate.
if it was twice as massive, earth probably have burned, noone would be here, and surviving would be a 1 out of 100,000
In that case, the Moon would move in a straight line instead of moving around the Earth; it would quickly get away.
If the moon were to suddenly fall directly on Earth, it would result in catastrophic consequences. The impact would likely cause widespread destruction, massive earthquakes, tsunamis, and potentially wipe out all life forms on Earth. It would be an extinction-level event.

The moon would spiral inward towards the Earth.
Then everything in space would fall for the ground due to the massive gravitational force that it is emitting.
There is no reason why it should. But if it did, there would soon be no life left on Earth.
If the Earth suddenly lost its constant velocity, it would result in drastic changes to our environment causing catastrophic events such as massive earthquakes, tsunamis, and extreme weather patterns. The loss of constant velocity would disrupt ecosystems, potentially leading to widespread destruction and loss of life.
Fish would die. There are species of fish that live off the algae.
If a hole to the center of the Earth suddenly opened up in your backyard, it would likely result in catastrophic consequences. The intense heat and pressure from the Earth's core would cause massive explosions and potentially lead to the collapse of the surrounding area. The release of molten rock and gases could also pose a serious threat to nearby structures and individuals. It is important to note that such a scenario is purely hypothetical and not scientifically possible.
In that case, the Moon would move in a straight line instead of moving around the Earth; it would quickly get away.
If the sun were to suddenly turn into a black hole, it would not affect Earth's orbit or cause it to be sucked in. However, the lack of sunlight would lead to a rapid drop in temperature, causing all life on Earth to perish.
