when we lighten a candle on earth the fire point upwards. What if we lighten the candle in a space shutte in space. To where the fire point?

Candle flames in space are spherical.
On Earth, when you light a candle, the burning wax heats the air around it and makes it less dense. Cooler, denser air pushes the warm air upward and gives an Earth-bound candle flame its characteristic upward sweep. This inrushing air also resupplies the oxygen that is consumed by the candle flame.
In the space shuttle you're in a continuous state of free-fall, which simulates having no gravity at all. There is no up or down, so warm air isn't pushed anywhere by cold air. The expanding warm air radiates outward in a spherical pattern from the candle wick, as does the visible flame. But without an influx of cool, oxygen-rich air, the oxygen can only be replenished by diffusion. This happens more slowly, so a candle flame aboard a space shuttle burns with very low intensity.
I hope that helps. Good luck!

The fire will be a ball, moving into all directions at the same tame
