If hypothetically a time traveler went back in time and started one,could the laws of Physics stop it?

If in fact time travel is not possible how do we travel forward through it every day?

Let's not worry about paradoxes. They are probably happening all the time - we just aren't aware of them. In other words? Hypothetical particle travels back in time, becomes anti-matter - - and annihilates itself. All before the events were set in motion to send it back in time in the first place.
Sound a little too much like science-fiction? Maybe. Maybe not. If quantum foam exists, wormholes are popping in and out of existence all the time.
If one expanded until it was big enough to engulf an atom?
Then maybe it could ALSO become anti-matter, travel backwards in time, and annihilate itself. Sounds like an interesting experiment.
That's the key word - experiment.
Let's just stop worrying about paradoxes - BUILD A TIME MACHINE - and experiment on things from there. How big would a quantum wormhole have to be, to prove time travel possible? As big as an atom? As big as an electron? As big as a quark?
Building one that's big enough for a human to use, that might take a very long time. But even at this stage of things, in our present knowledge of physics, there are people talking about building microscopic black holes. CERN is an ongoing project. So let's build a MICROSCOPIC WORMHOLE while we are at it - and answer our questions that way.
Then there will be no more speculation.
Everything will be science - not science-fiction.

I'm pretty sure the laws of physics do not allow for time travel in the first place.

If time travel did exist and we will discover it, then how come NO ONE has EVER come back to tell us so? I mean, since time stretches on forever, you get the idea that at least once someone would come back and make it public knowledge. Kinda depressing when you think about it.

No, there are no laws in physics that could stop a paradox, but there are plenty of paradoxes in the laws of physics.
That even confused me, and I wrote it.
