I understand that the universe is expanding due to hubble's constant and the proof that this can show that the universe is expanding, i just would like to know what physicists suggest the universe is expanding into?
Thanks

The universe is not expanding into anything. It is expanding within itself.
The current scientific understanding is that the universe is infinite and has no edge or boundary. It is constantly expanding and has no specific endpoint.
Dark energy is the hypothetical force that is believed to be causing the expansion of the universe to accelerate. It is thought to make up about 70% of the total energy in the universe.
Based on current observations and models, it is believed that the expansion of the universe will continue indefinitely and will not reverse or stop. However, new discoveries and theories could potentially change this understanding.
The expansion of the universe cannot be observed directly, but it can be measured through various methods such as studying the redshift of galaxies and the cosmic microwave background radiation.
