The reason is because newer versions have items, blocks, mobs, and changes to NBT data that are not recognized by older versions; since 1.9 the game records the version a world was last loaded in but older versions do not recognize this data for the same reason, so they do not warn you when you try to load them.
If you really want to downgrade a world you have to use a utility like MCEdit to delete or replace all unknown items, blocks, mobs, and anything else, such as tile entities, that have different NBT data. Note that in the case of items this applies to all items because in 1.8 they changed the way they are saved and at the least they will all disappear (the game may also regenerate the chunk they are in). If it is a custom map you downloaded that was made for an older version and you first played it in a newer version you'll have to redownload or replace it. I also recommend that you make a new profile for that version, and use a different game directory (just change .minecraft to something else, or add a new subfolder and run the game once so it creates the directory structure, then you can place the world into the saves folder within it).

Curse PremiumI've tried creating a world in 1.10 and did not get any crash
This is not a problem with your computer - downgrading is NOT supported and WILL corrupt the world.
See:
http://www.minecraftforum.net/forums/minecraft-discussion/recent-updates-and-snapshots/2201993-so-what-happens-if-you-create-something-in-1-8-and
MC-45009 Inventory and container empty/world corrupted after downgrading to older version.
The reason is because newer versions have items, blocks, mobs, and changes to NBT data that are not recognized by older versions; since 1.9 the game records the version a world was last loaded in but older versions do not recognize this data for the same reason, so they do not warn you when you try to load them.
If you really want to downgrade a world you have to use a utility like MCEdit to delete or replace all unknown items, blocks, mobs, and anything else, such as tile entities, that have different NBT data. Note that in the case of items this applies to all items because in 1.8 they changed the way they are saved and at the least they will all disappear (the game may also regenerate the chunk they are in). If it is a custom map you downloaded that was made for an older version and you first played it in a newer version you'll have to redownload or replace it. I also recommend that you make a new profile for that version, and use a different game directory (just change .minecraft to something else, or add a new subfolder and run the game once so it creates the directory structure, then you can place the world into the saves folder within it).
TheMasterCaver's First World - possibly the most caved-out world in Minecraft history - includes world download.
TheMasterCaver's World - my own version of Minecraft largely based on my views of how the game should have evolved since 1.6.4.
Why do I still play in 1.6.4?
