Is time travel to the past or travel to a multiverse possible?

In summary, there is currently no evidence or advancements in physics that suggest time travel to the past or to alternate universes is possible. The way we have observed the universe to work does not support these ideas, and anyone claiming otherwise would need to provide evidence for these specific phenomena.

And how is it possible or not possible?

Can you also take into consideration the new advancements in physics.

thanks

I am unaware of any new advancements in physics that suggest that time travel to the past is possible. And other than time dilation, the same goes for time travel forwards. Also, there is absolutely no evidence that multiverses exist let alone whether we can travel to them.

These things aren't possible simply because everything we have observed tells us that this does not happen. We cannot explain why it isn't possible, only tell you that it is not the way we have observed the universe to work. Anyone claiming that either of these things is possible would need to provide evidence for this exact phenomena.

Drakkith has given you the answer but if you want to read long, useless discussions about it, just do a forum search ... the topic has been beaten to death here.
 

FAQ: Is time travel to the past or travel to a multiverse possible?

Is time travel to the past possible?

At this time, we do not have the technology or scientific understanding to travel back in time. The laws of physics, specifically the second law of thermodynamics, suggest that time travel to the past is not possible.

Can we travel to a parallel universe or multiverse?

There are various theories and hypotheses about the existence of a multiverse, but at this time, there is no scientific evidence to support its existence. Therefore, we do not have the technology or understanding to travel to a parallel universe.

Is time travel to the future possible?

According to Einstein's theory of relativity, time dilation suggests that an object traveling at high speeds will experience time slower than an object at rest. Therefore, theoretically, time travel to the future is possible, but it would require traveling at extremely high speeds.

How do wormholes relate to time travel?

Wormholes are a theoretical concept in which two distant points in space and time are connected, creating a shortcut or tunnel through space-time. While wormholes are currently only a theoretical concept, they could potentially be used for time travel in the future.

Can we change the past if time travel were possible?

This is a highly debated question among scientists and philosophers. One theory suggests that if time travel were possible, any changes made in the past would create a new timeline or parallel universe, rather than altering our current timeline. However, there is no way to confirm this without the ability to time travel.
