Just before the scene where Mo, Darby and Izzy use stealth mode to turn invisible to sneak past all the bugs, Izzy mentions that she and her grandma used to use stealth mode to play hide and seek all the time, yet she had no idea about the time limit stealth mode has and got caught up in the middle of the swarm of bugs when the timer ended.

During the ending sequence, Buzz and his crew climb into a spaceship, and the ship then gets tilted with the nose facing upwards so that it can blast off. Sox then jumps onto the console of the ship so he can get plugged into it, even though at that angle he definitely should have fallen off, he literally just sat down on a solid vertical surface.

If using crystallic fuel causing time dilation is a known fact in this movie's universe, Buzz should have known that it would have happened before he started doing the first test. Yet it seemed like nobody had any idea that it would have happened until he came back.

Time dilation is real, and can be seen with astronauts and satellites in real life. Someone who spends 10 years traveling at 99% the speed of light will come back about 72 years later on Earth.

However, Buzz's test launches are for seconds at a time- at most, he is "skipping" about 45 minutes per launch, with a maximum of 75 minutes.

Assuming the 10 or so tests we see are all he did, he is "time displaced" no more than a few hours, not the decades seen in the film. Of course, physics may work differently in his universe.

When Buzz is trying to slow down the ship falling through the atmosphere, the hull of the ship is visibly red-hot due to the high velocity and air resistance. However, Buzz suit, moving with the same velocity, does not have the same effect.

Buzz mentions working in "the Galaxy," which in astronomy is a shorthand for the Milky Way, the galaxy that is home to Earth; other galaxies are referred to with specific names. But at a distance of 4.2 million lightyears, Buzz and company are far outside of the Milky Way.

When Buzz begins entering the amounts for the liquid components for the crystal to be made, the amounts he enters are measured in less than one milliliter. One milliliter is about as much as much as an eyedropper holds, so unless this movie takes place in a universe where humans are only a few inches tall, the volume of liquid visibly shown is way too much to be less than a milliliter.

A children's movie made in 1995 very likely would not have LGBTQ representation in it.

The opening text reveals that in 1995, Andy received a Buzz Lightyear toy that was part of this movie's merchandise. However, this movie features computer animation that is too advanced for 1995. It does not look like a movie that was released in 1995.

The hyper speed shown in the movie is extremely slow considering the distances involved. When Buzz is doing the fuel tests his speed is measured in c, with 1c being 100% hyper speed. In physics 1c is the speed of light.

The text at the start of the movie states T'Kani Prime is 4.2 million light years from Earth, which means it would take 4.2 million years to travel that distance at the speed of light. Given the Turnip is supposed to be an exploration ship, an 8 million year round trip does not seem practical.

Since Sox is a robot, he could have simply saved a copy of the crystal formula in his memory, especially since its just a set of 4 different percentages they need to input.

Sox states "at 3 o'clock" but the target is dead ahead (or at 11 o'clock at the most).

Zurg should have no reason to try to pursue Buzz and steal the crystal after his ship got blown up, as he needed his ship to go back in time, which is his whole goal.
