✅ YES: Time Dilation (Forward Time Travel)

🔭 What happens:

• Near a black hole, gravity is extremely strong.
• According to Einstein’s General Relativity, time moves slower in stronger gravitational fields.

⏳ So if you:

• Orbit a black hole (especially a rotating one) near the event horizon,
• Then come back to Earth after, say, 1 hour,
• You might find that years have passed on Earth.

This is a kind of forward time travel — proven by both theory and small-scale experiments (like with atomic clocks in airplanes or satellites).

✅ This is real and possible (in theory), though we can’t yet travel near a black hole safely.

❌ NO: Backward Time Travel

• Going back in time is not supported by current physical laws.
• Some solutions to Einstein’s equations (like wormholes or closed timelike curves) suggest it might be possible.
• But these require exotic matter, negative energy, or violate causality — and none of this is proven or physically realistic yet.

🌀 Rotating Black Holes (Kerr Black Holes) & Wormholes

• Theorists like Kip Thorne showed that wormholes might connect two different points in space and time.
• If stabilized, they could potentially be time machines.
• But it’s all speculative — we don’t have the technology or the exotic materials.

🎬 Pop Culture Example

In Interstellar, the character spends time near a supermassive black hole (Gargantua), and when he returns, 23 years have passed outside while only hours passed for him — this is real physics (time dilation).
