What would Arwen's baby look like?

[The Squatter of Amon Rûdh]

here is what I think and I really don't care if it is contradictory to some research for it is how I interperated the story.

In that case, here's why you're wrong for the benefit of those people who do care about accuracy:

'"What is that doom?" said Aragorn.
'"That so long as I abide here, she shall live with the youth of the Eldar," answered Elrond, "and when I depart, she shall go with me, if she so chooses."
"I see," said Aragorn, "that I have turned my eyes to a treasure no less dear than than the treasure of Thingol that Beren once desired. Such is my fate." Then suddenly the foresight of his kindred came to him, and he said: "But lo! Master Elrond, the years of your abiding run short at last, and the choice must soon be laid on on your children, to part either with you or with Middle-earth."
"Truly," said Elrond. "Soon as we account it, though many years of Men must still pass. But there will be no choice before Arwen, my beloved, unless you, Aragorn Arathorn's son, come between us and bring one of us, you or me, to a bitter parting beyond the end of the world..."

The quotation above is from Appendix A to The Lord of the Rings. Arwen must choose, as must all the Half-elven, whether she will accept the fate of the Elves or of Men. She chooses mortality because of her love for Aragorn, but she would have to make the choice even if she had never met him.

If this isn't enough, there is an example in the Silmarillion of an Elf who marries a Man and does not become mortal: Idril Celebrindal, the wife of Tuor and mother of Eärendil. She has no choice laid before her because she is of entirely Eldarin descent [not to mention that her family has had no special privilege granted - second edit].

Not being interested in what research may reveal does not, I'm afraid, prevent it from proving your opinion wrong; although I'd hardly call reading the books carefully 'research'.

[Second edit: my eccentric capitalisation of 'Half-elven' seems to have caused some confusion, so I've changed it to look more like a title.]
